Known Issues

The following sections provide information about known issues and bugs filed against this product release:

If a recommended workaround is available for a bug, it follows the bug description.

iSCSI Issues

NEBS Compliance of ST 2510 Array

The ST 2510 array is not currently NEBS Level 3 compliant. It will become compliant approximately 8 weeks post-RR. Customers relying on this NEBS certification should check with their Sun representatives before acquiring this array for NEBS-specific applications to verify that the ST 2510 is certified.

Out-of-Band Management May Lose Connectivity

Bug 6615356 - SYMbol task ServsymRpcHandle periodically dies, causing the management software to lose communication with the array.

The cause has been identified and will be corrected in future releases.

Workaround - Rebooting the array corrects the problem.

Negative Values Returned for iSCSI Statistics Counters

Bug 6611655 - Negative counter values display for iSCSI Statistics large counter values. The values should be unsigned.

Workaround - Resetting the baseline under Administration->Performance in the management software resets the values.

Initiator with the Same Name as a Host Creates an Error

Bug 6624755 - For iSCSI on the 2510 Array only, creating an initiator with the same name as a host returns error message 57: “The operation cannot complete because the identifier or name you provided already exists. Please provide another identifier or name and then retry the operation.”

Workaround - Do not create an initiator with the same name as a host.

2510 Array Shows as Host Board Type “Unknown”.

Bug 6620100 - For the 2510 Array, the Controller Summary page of the management software shows the Host Board Type as UNKNOWN. For example:

public static final int HB_TYPE_UNKNOWN 1

Workaround - Keep a manual record of iSCSI host boards.

IPv6 Statistics Display on iSCSI TCP/IP Page

Bug 6651908 - IPv6 performance statistics display on the iSCSI Performance - Ethernet - TCP/IP page in the management software. They should not.

Workaround - Ignore the IPv6 performance statistics on this page.

SAS Issues

SAS Ports Link Status May Be Incorrect

Bug 6560293 and 6650124- The SAS port link status in the management software may be incorrect.

Workaround - None.

Removing a SAS Controller Results in False Status

Bug 6522947 - Removing a SAS controller results in outdated information on the Controller Details page in the management software. The status correctly reports the controller as removed. Replacing the controller corrects the state.

For SAS, Creating New Volumes During Heavy Input-Output Can Result In Errors

Bug 6522938 - For SAS, using the CLI to create a new volume on an array with high data input and output returns in a timeout and an error code of 4.

Workaround - Verify if the new volume was created and if not try the operation when there is less I/O traffic.

Hardware and Firmware Issues

This section describes general issues related to the Sun StorageTek 2500 Series Array hardware and firmware.

World Wide Port Names Cannot be used as Initiators

Bug 6527155 - Do not use World Wide Port Names as names for initiators. Doing so will result in serious problems in array operations. The Common Array Manager software will prevent you from doing this.

Service Required LED Lights After Data Host Power On

Bug 6587720- The Array Service Required LED will light after powering down a data host, connecting FC cables between the HBA and controllers, and powering up the host server.

This is working as designed. Under a Direct Connect environment, rebooting the connected data host will cause a FC link down alarm. This is an expected alarm and the Amber Service Required LED is expected to illuminate. As soon as the link is back up, the Alarm should clear and the LED should turn off. The same behavior would be expected if a cable were unplugged form the HBA, or if there was a error with the HBA port or the HBA itself.

Under a switch environment, this will not occur unless a cable is unplugged from the switch, the switch is rebooted, or is having errors. Rebooting the host will not cause the link to go down because the link from the controller SFP to the switch will remain 'up'.

Plugging Cable into Wrong Port on a Hot System Can Cause a Panic

Bug 6541881 - A cable pull returned to the wrong HBA port can cause a panic. The cause is known and a fix is being worked on.

Workaround - Try to ensure that you plug the cable back into the port it was originally in if your system is running. If you need to move the cable to a different port, try to do so when the system is not online.

Disabled Snapshot can be Re-enabled after a Firmware Update

Bug 6529172 - A snapshot volume that is disabled can be automatically re-enabled after a firmware update occurs. If the snapshot volume is full, it can start generating warning events.

Workaround - Disable the snapshot again after the firmware update.

Adding Expansion Unit with Existing Storage Domain Info can Cause Event

Bug 6550702 and 6547615 - If you migrate an expansion module with licensed storage domains into an array that has a different number of licenses, an alarm will be generated.

Workaround -For a mismatch of license numbers, disable the licenses on the expansion module. Then disable the storage domains on the expansion module. The array will return to the licenses for the array (which is compliant), and the alarm will clear. Add any new licenses, if needed.

Port Speed should be ”Unknown” for a Link that is in a Down State

Bug 6560279 - When a FC port is not connected to a Fabric or FC-AL topology, the Port Summary table reports the speed as 4Gbps. The port speed should read “Unknown” in the Summary page.

Array Returns Drive Type as "All" if One of the Removed Disk is Configured as a Hotspare

Bug 6581396 - The sscs list fru command displays Disk Type and Description as "All" and "All disk drive" respectively for a removed disk drive which was configured as a hotspare.

It should display "Unknown" as a drive type and "Unknown disk drive" in the Description field.

Upgrading IOM Firmware Can Result In Failback Failure

Bug 6509762 - After a firmware upgrade to an Input-Output Module (IOM), the array will display a Check Condition - Microcode Changed message on all hosts.

After a firmware upgrade, an automatic failback was generated. When the switch port connecting the data host was enabled, the auto failback failed, indicating that it did not process the MICROCODE_CHANGED message.

Workaround - There are two workarounds:

1) Perform a manual failover. The issue will not happen.

2) After updating the IOM firmware, manually forcing a failover and failback of all effected LUNs on any mapped Solaris host will clear out the condition.

Failover May Generate False Error Messages

Bug 6509331 - In Solaris, under heavy data traffic, host-initiated failover may generate error messages in /var/adm/messages even though the failover is successful.

Workaround - In the CLI, use the Solaris luxadm command to verify that the failover was successful.

Pushing Drive Housing Too Far Unseats Drive

Bug 6514411 - Inserting a disk drive into a tray by pushing on its housing until it is all the way in causes the drive to stop without being fully inserted and with the drive handle protruding.

Workaround - The correct way to insert a disk drive into the tray is as follows:


procedure icon  Remove and Replace a Disk Drive

1. Push the release button next to the disk drive to release the latch handle.


Figure 1 The Drive's Release Button and Latch/Handle.

FIGURE 1 Releasing the Latch Handle



caution icon Caution - Potential loss of data access - Data might be lost if an active disk drive is removed. If you remove an active disk drive accidentally, wait at least 30 seconds before reinserting it.


2. Use the latch handle to slowly pull the failed disk drive out of the tray.



caution icon Caution - Use care when handling any disk drive. Make sure all ESD precautions are being followed.


3. When the drive is removed push the latch handle in to protect the failed disk drive from damage.

4. Unpack the new disk drive and do one of the following:

5. Wait 30 seconds after the failed disk drive has been removed.

6. On the new disk drive, push the release button to release the latch handle.

7. Partially insert the drive into desired slot location. See FIGURE 2.



caution icon Caution - In some drive bays, full insertion at this point without controlling the motion of the lever may cause the lever to bind.


Figure 2 Inserting the Drive

FIGURE 2 Inserting the Drive.

8. Grasp the lever and continue inserting the drive until you can easily rotate the lever toward the closed or latched position. See FIGURE 3.



FIGURE 3 Pushing the Disk Drive Latch.

9. Press firmly on the lever until it latches and the drive is fully inserted. See FIGURE 4.



Note - Pressing harder should not cause additional inward motion of the drive.


The latch handle will click into place when the drive is fully inserted.


Figure 4 Pressing the Lever to Fully Insert the Drive.

FIGURE 4 Fully Inserting the Drive.

10. After the disk drive is fully inserted, the green Ready/Active LED will flash and then remain on to indicate a ready state.

A flashing Ready/Active LED indicates that data is being restored to the new disk drive.



Note - Depending on your configuration, the array might automatically reconstruct data to the new disk drive. If the array uses hot spares, it might need to complete reconstruction on the hot spare before it copies the data to the new disk drive. This could increase the time required to complete this procedure.



procedure icon  Verify and Complete the Disk Replacement

1. Access the Service Advisor software and verify that the State value is Enable and Status value is OK for the new disk drive

If the State and Status values are not Enable and OK, contact your Sun Service provider or your next level of technical support.

2. From the Service Advisor software, do the following:

On x86 Platform, luxadm probe Command Displays Entries of UTM (Management) LUNs

Bug 6482519 - The luxadm probe command displays UTM LUNs on x86 platforms. The UTM (Management) LUN is a reserved space, normally hidden, where the specific configuration settings for your array are stored.

Recharging a Battery in a Controller Results in a Failed Battery Event

Bug 6502673 - A battery replaced in a controller reports a failed battery event, while it is recharging. After the battery is fully recharged, this alarm will go away.

Battery Events Do Not Identify the Battery’s Controller Location

Bug 6503171 - Battery event messages do not specify which of the two controllers the referenced battery is in.

For battery events, the array only reports the tray where it occurs, not the slot.

Workaround - For non-critical events, collect the support data and find the corresponding event in the MEL log. For critical events, the third amber LED lights on the front of the controller with the failed battery.

A Bad SFP May Not Generate a Fault Indicator

Bug 6514739 - If a bad SFP is inserted in the FC port of a 2540 array, there may not an indication in the fault list that it is bad.

Certain failure modes of an SFP may not be detected by the array firmware immediately upon insertion and the management software could report the link state as optimal.

However, when you initiate I/O on the channel with the damaged SFP, it will be reported as failed.

Workaround - Check the fault LED and link LED for link failure. Check the event log for a failure event at the time of the SFP insertion and when you initiate I/O.

Insufficient Reserve Space Fails Resnap

Bug 6523608 - Refreshing a snapshot does not update the filesystem if there is insufficient reserve space, yet a message displays indicating success. The array’s event log says the resnap completed successfully.

Workaround - In the snapshot feature of the management software, configure snapshots to fail if sufficient reserve space is not available. The fail message will prompt you to increase the reserve space.

Array Does Not Timeout and Clear Pending Firmware Download Session of Previous Failure

Bug 6523624 - If a firmware upgrade to an expansion module fails, the array may not clear the failed session automatically.

Workaround - After 20 minutes, retry the upgrade. If the upgrade fails again, power cycle the array to clear the failure.

Increased Common Array Manager Response Time

A busy array can increase the management software’s response time.

Service Advisor Does Not Verify Disk is Ready to be Removed

Bug 6501029 - When the management software lists a disk as failed and the Service Advisor procedure for replacing drives is followed, the step to verify that the disk is ready to remove may not list the failed disk.

Workaround - Use an alternative menu option, Array Troubleshooting and Recovery, to view the status of the disk.

Documentation Issues

This section describes known issues and bugs related to the Sun StorageTek 2500 Series Array release documentation.

Third Expansion Tray (48 Drive) Cabling

A patch is available for Release 6.0.1 that adds support for a third expansion tray and 48 drives. Cabling instructions for the third expansion tray has not yet been added to Sun StorageTek 2500 Series Array Hardware Installation Guide or Service Advisor.

Array Configuration Naming Convention

The configuration naming convention is “controllers x trays” where the first number is the controller tray and the second is the sum of the controller tray and the number of expansion trays. For example, 1x1 is a standalone controller tray, 1x2 is the controller tray and one expansion tray, 1x3 is the controller tray and 2 expansion trays, 1x4 is the controller tray and 3 expansion trays (TABLE 13).

Note - Do not add more expansion trays than the array supports.


Use the following instructions to connect the dual-RAID controller tray to one or more expansion trays.

Connecting Expansion Trays

Keep the following points in mind when adding expansion trays to your storage array:

Cabling an Expansion Tray to a Controller Tray

A Controller tray has two expansion ports, one on the Controller A module and one on the Controller B module. To connect an expansion tray, connect an SAS cable from each expansion port on the controller to each In port on the expansion tray. TABLE 14 shows a 1x2 array configuration consisting of one controller tray and one expansion tray. Two SAS cables are required.

Figure showing interconnection cables between a CRM and a single CEM.

TABLE 14 1x2 Array Configuration Cabling Example

 

To cable a 1x2 array configuration:

1. Locate the Controller A and Controller B expansion ports at the back of the controller tray (TABLE 14).

2. Locate the In and Out expansion ports at the A-side and B-side back of the expansion tray (TABLE 14).

3. Connect one SAS cable between the Controller A expansion port and the A-side In port on the expansion tray (TABLE 14).

4. Connect one SAS cable between the Controller B expansion port and the B-side In port on the expansion tray (TABLE 14).

Cabling Additional Expansion Trays

Each additional expansion tray is added to the preceding expansion tray by connecting SAS cables from the Out ports of the first tray to the In ports of the next tray. TABLE 15 illustrates a 1x3 array configuration consisting of one controller tray and two expansion trays. The cable connections on the B-side are reversed (the cable from the controller A expansion port goes to the In port of expansion tray 1; the cable from the controller B expansion port goes to the In port on expansion tray 2) for maximum redundancy. This pattern continues for each additional tray you add. Two more SAS cables are required for each additional tray.

Figure showing interconnection cables between 2 expansion trays and one controller tray.

TABLE 15 1x3 Array Configuration Cabling

 

To cable a 1x3 array configuration for maximum redundancy:

1. Locate the Controller A and Controller B expansion ports at the back of the controller tray (TABLE 15).

2. Locate In and Out expansion ports at the A-side and B-side back of the expansion tray (TABLE 15).

3. Connect one SAS cable between the Controller A expansion port and the A-side expansion In port of expansion tray 1 (TABLE 15).

4. Connect one SAS cable between the Controller B expansion Out port and the B-side expansion In port of expansion tray 2 (TABLE 15).

5. Connect one SAS cable between the expansion tray 1 Out port and the A-side expansion In port of expansion tray 2 (TABLE 15).

6. Connect one SAS cable between the expansion tray 2 B-side Out port and the B-side In port of expansion tray 1 (TABLE 15).

Figure showing interconnection cables between 2 expansion trays and one controller tray.

TABLE 16 1x4 Array Configuration Cabling

To cable a 1x4 array configuration for maximum redundancy:

1. Locate the Controller A and Controller B expansion ports at the back of the controller tray (TABLE 16).

2. Locate In and Out expansion ports at the A-side and B-side back of the expansion tray (TABLE 16).

3. Connect one SAS cable between the Controller A expansion port and the A-side expansion In port of expansion tray 1 (TABLE 16).

4. Connect one SAS cable between the Controller B expansion Out port and the B-side expansion In port of expansion tray 3 (TABLE 16).

5. Connect one SAS cable between the expansion tray 1 Out port and the A-side expansion In port of expansion tray 2 (TABLE 16).

6. Connect one SAS cable between the expansion tray 3 B-side Out port and the B-side In port of expansion tray 2 (TABLE 16).

7. Connect one SAS cable between the expansion tray 2 Out port and the A-side expansion In port of expansion tray 3 (TABLE 15).

8. Connect one SAS cable between the expansion tray 2 B-side Out port and the B-side In port of expansion tray 1 (TABLE 15).

 

Solaris 8 Not Supported For Data Hosts

The Sun StorageTek 2500 Series Array Hardware Installation Guide, part number 820-0015-10, lists Solaris 8 as supported for data hosts. Only Solaris 9 and/or 10 are supported, depending on the application.

Add Expansion Modules with Array Power On.

Bug 6538943 - The Sun StorageTek 2500 Series Array Hardware Installation Guide, Part No. 820-0015-10, states in Chapter 2:

“Expansion trays must be added with the power to the array and I/O data transfer turned off.”

This is incorrect. It is best to add an expansion tray to a running array instead of one that is powered off. Limiting I/O traffic is recommended for the duration of the reconfiguration.

1x3 Cabling Procedure Error

Step 6 on page 51 of Sun StorageTek 2500 Series Array Hardware Installation Guide states, “Connect one SAS cable between the expansion tray 2 B-side Out port and the B-side In port of expansion tray 2.” This is incorrect. You should connect the cable between the expansion tray 2 B-side Out port and the B-side In port of expansion tray 1.

Corresponding Figure 19 is correct.

Default IP Address Netmasks

The Sun StorageTek 2500 Array Hardware Installation Guide documents the default IP addresses (Configuring IP Address of the Array Controllers), but does not include the netmask. The netmask for the default addresses is 255.255.255.0.

Flathead Screwdriver Required

Bug 6515249 - In Chapter 2 of the Sun StorageTek 2500 Array Hardware Installation Guide the list of tools needed for the array installation in a rack does not list a flathead screwdriver, which is required if you need to loosen the rail extension screws.

Service Life of Battery is Three Years

The service life of the battery pack is three years, at the end of which the battery pack must be replaced. The Sun StorageTek 2500 Array Hardware Installation Guide incorrectly lists the life as two years.

Operational Information

This section provides useful operational information not documented elsewhere.

In-band Requirements for Linux

In-band for Linux requires Linux Red Hat Enterprise v5.1.

Wait 60 Seconds Before Replacing Drives

When a drive fails, wait 60 seconds after removing the failed drive before you put in a new drive.

License Required for Storage Domains

The 2500 Series array includes two storage domains. You must purchase a premium license to use additional storage domains.

When Performing an Array Import, Do Not Modify Configuration

Configure management objects while an import array job is running might interfere with the import. Be sure that everyone who uses the destination array does not configure any objects (including volumes, initiators, mappings, etc.) while the import is in progress.

Using a Volume Before It Is Fully Initialized

When you create a volume and label it, you can start using the volume before it is fully initialized.

Controller Tray Battery Information

During boot-up, the battery light might flash for an extended period. The battery charger performs a series of battery qualification tests before starting a battery charge cycle. This series of tests occurs at subsystem power-up. The tests are automatically reinitialized approximately every 25 hours by a timer.

Each controller tray contains a user-replaceable lithium ion battery pack for cache backup in case of power loss. The on-board battery is capable of holding a 2-gigabyte cache for three days (72 hours). The service life of the battery pack is three years, at the end of which the battery pack must be replaced (it is field-replaceable).
