This section describes the main features of the Sun StorageTek 6540 Array, including the following:
The following new features are available for the Sun StorageTek 6540 Array
Auto Service Request (ASR) is a new feature of the array management software that monitors the array system health and performance and automatically notifies the Sun Technical Support Center when critical events occur. Critical alarms generate an automatic Service Request case. The notifications enable Sun Service to respond faster and more accurately to critical on-site issues.
The Auto Service Request capability in Sun StorageTek Common Array Manager software allows you to register devices to participate in the ASR service. Refer to the Sun StorageTek Common Array Manager Release Notes, Release 5.1.3 or higher, for more information.
Controller firmware 06.19.25.10 or higher allows tray mixing of 6540, 6140 and 6130 array controllers modules and the Sun StorageTek CSM100, CSM200, FLA200, FLC200, and FLA300 Expansion Modules.
| Note - To add trays with data already on them, contact your service representative for assistance to avoid data loss. |
Refer to “Upgrading Firmware for Adding Expansion Trays” in the Sun StorageTek Common Array Manager Release Notes, v.5.1.3 or higher, for more information on the procedure to upgrade trays without data. Also refer to Best Practices for Adding Expansion Modules
TABLE 1 lists the supported expansion modules.

Supported Expansion Modules with Controller Firmware 06.19.25.10 or higher |
||
|---|---|---|
Only Sun Service should install expansion modules with data. Refer to the Sun StorageTek Common Array Manager Release Notes, Release 5.1.3 or higher, for more information about supported expansion modules by array.
When you add a new CSM200 expansion module to an existing array in a production or active environment, it is best practice to cable and add the trays while the RAID controller module is powered on, in order to avoid a variety of issues including those listed below.
Before connecting any replacement drive or additional expansion module to an existing functioning array, it is best practice to contact Sun Microsystems Support Services. One reason for this is to avoid issues related to DACstore, the configuration and status database maintained by the array firmware, that stores its information on each of the disk drives.
Contact Sun Microsystems Support Services promptly upon experiencing any of the following symptoms:
The Sun StorageTek 6540 Array is a 4-Gb/2-Gb/1-Gb Fibre Channel (FC) array that offers both direct attached and storage attached network (SAN) access. The Sun StorageTek 6540 Array includes the following features:

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.
This section describes known issues and bugs related to installing and initially configuring the Sun StorageTek 6540 Array.
Bug 6455157 - In the x-option case, the array controller reads in Sun StorageTek 6140 NVSRAM from the I/O Modules and is then listed and detected as a Sun StorageTek 6140 controller. As a result, the Sun StorageTek Common Array Manager software fails to update the firmware properly. This problem occurs only with controllers for the Sun StorageTek 6540 Array that are connected in the field with Sun StorageTek CSM2 expansion trays. It does not apply to factory-installed Sun StorageTek 6540 Arrays.
Workaround - Use the CLI to upgrade the array firmware, as follows:
On a Solaris management host, use the CLI to enter the following commands:
cd /opt/SUNWstksm/bin ./csmservice -i -p 117856-35:121540-02:121540-02
On a Windows management host, use a terminal window to enter the following commands:
C:> cd \Program Files\Sun_Microsystems\StorageTek_Mgmt\Component\SunStorageTekSoftwareManager C:> .\csmservice -i -p 117856-35:121540-02:121540-02
The script prompts you with a list of the registered arrays. Select only the IP for the Sun StorageTek 6540 controller that you are trying to upgrade. When the firmware upgrade is complete, unregister (remove) the array in the software and then register the array again.
Bug 6418696 - Controller tray IDs can be set to any number between 0 and 99. Because expansion trays use the values 0 to 79, controller trays should use the values 80 to 99 (except 85) to avoid duplicate tray IDs. If tray IDs are duplicated, the array will not be able to detect the drives on one of the two trays that have the same ID (which one is arbitrary). Do not use ID 85 for the controller tray, as this number is the default setting that indicates everything is operating as expected.
Workaround - Use the values 0 to 79 for expansion trays and 80 to 99 (except 85) for controller trays and ensure that any assigned tray ID value is not a duplicate.
Bug 6449021 - Removing a battery does not light (as amber) the corresponding LED in the upper corners of the interconnect module.
Bug 6451036 - With the patch installed, changes with the cfgadm command are lost upon rebooting.
Workaround - Force the configuration update (of the /etc/cfg/fp/fabric_WWN_map) with the following commands:
cfgadm -c configure -o force_update cx
This section describes general issues related to the Sun StorageTek 6540 Array hardware and firmware.
|
Caution - The front and back doors of the system cabinet must be closed for compliance to domestic and international EMI regulations as well as proper equipment cooling. |
Do not block or cover the openings of the system cabinet.
Cabinet airflow is from front to back. Allow at least 30 inches (76.2 cm) in front of the cabinet, and at least 24 (60.96 cm) inches behind the cabinet, for service clearance, proper ventilation, and heat dissipation.
Bug 6371462 - The switch setting 2 Gb/s or 4 Gb/s applies to the speed of the internal FC data path to disk drives. When a 2-Gb/s drive is set to 4 Gb/s, the drive enters a status of Bypassed.
Volumes on Bypassed drives are marked as Missing and lose their pool assignment. They are displayed on a separate Ghost Volumes list, with minimal info available.
Workaround - Power off the arrays and set the link rate switch back to 2 Gb/s.
Bug 6430195 - If you power off, remove, or experience a failure of either of the power cooling units, the system generates battery alerts for both batteries as “transitioning to an unknown state.”
Even though the batteries are listed as being in an unknown state, they are still providing protection in the event of a cache failure. No workaround is required.
Bug 6430195 - If you power off, remove, or experience a failure of either of the power cooling units (which also house the controller’s battery packs), the system generates battery alerts for both batteries as “transitioning to an unknown state.”
Workaround - You should not lose data unless the batteries fail, or unless you do not have adequate charges remaining in the batteries for cached data to finish being written to disk.
Bug 6438824 - There is a module on the array, physically labeled ESM, that is identified by Sun StorageTek Common Array Manager software as an input/output module (IOM).
Bug 6411928 - Switch ports used for the dedicated link in a remote replication are not automatically usable as regular ports when the replication link is removed.
Workaround - Disable and re-enable the switch port to make it usable for regular data access.
Bug 6417872 - When Small Form-factor Pluggables (SFPs) are installed into the I/O Module (IOM) 2A and 2B ports, the front amber fault LED lights and the IOM displays an “H8” error.
Workaround - Do not install SFPs into these slots; they are reserved for future use.
Bug 6180131 - Using a faulty expansion cable causes the management software to report the array health as Degraded and causes the management software to report the error Drive tray path redundancy lost. However, the status LED on the front of the chassis does not signal an error and remains green instead of turning amber, as expected.
If a volume failure on a Sun StorageTek 6540 Array results from failed disk drives and you introduce replacement drives that were part of a volume in use by another Sun StorageTek 6540 Array, the array might incorrectly initiate a volume migration process with the replacement drives.
Workaround - Perform one of the following tasks:
Bug 6444767 - The procedure to remove and replace a power cooling unit in the Service Adviser section of the Sun StorageTek Common Array Manager software applies to the controller tray, not the expansion trays.
Workaround - Use the following procedure to replace a power cooling unit in the expansion tray.
From the rear, power cooling unit A is located in the upper right corner of the tray and power cooling unit B is located in the lower left corner of the tray.
1. Locate the failed power cooling unit by checking the fault lights. If a fault is detected, the Service Action Required LED (amber) will be on and the Service Action Allowed LED (blue) should be on.
Important: Never remove a power cooling unit unless the blue Service Action Allowed LED is On. Otherwise, you could lose data access by removing the power cooling unit.
2. Push the power switch on the failed power cooling unit to the Off position.
3. Unplug the power cord from the failed power cooling unit.
4. If power cooling unit A is being replaced, lift the latch handle up to unlock the unit and pull it out of the tray. If power cooling unit B is being replaced, pull the latch handle down to unlock the unit and pull it out of the tray. FIGURE 1 shows the removal of power cooling unit B.
FIGURE 1 Sample Removal of Power Cooling Unit B
5. Unpack the new power cooling unit, and save the packing materials for the failed unit. Use care when handling both the new and the failed power cooling units.
6. Ensure that the power switch on the new power cooling unit is in the Off position.
7. Insert the new power cooling unit until it connects with the midplane connector, and push the latch handle into the locked position.
8. Plug the power cord into the new power cooling unit.
9. Push the power switch to the On position.
10. The green power-fan LEDs should now be on. If this is not the case, contact your Customer Service representative.
The patch panel modem power cord is not connected to the cabinet power strip from the factory. To use the modem, power up the system before connecting the modem power cord to the cabinet power strip.
Bug 6451036 - These patches attempt to update the /etc/driver_aliases file using the add_drv command to cause UTM LUNs to bind to the SCSI Enclosure Services (SES) driver. If the SES driver is already loaded on the system when the add_drv command occurs, the /etc/driver_aliases file is not updated.
In addition, a patch is included for the SCSI Disk (SD/SSD) drivers that causes them to reject UTM LUNs. If the above driver_aliases file addition fails, the UTM LUNs do not bind to the SES driver.
The following issues are related to the SAN driver.
Bug 6362850 - The cfgadm -c unconfigure command unconfigures Universal Transport Mechanism (UTM) LUNs only and not other data LUNs. When this happens, you will not be able to unconfigure LUNs.
Workaround - Obtain Solaris 10 patch 118833-20 (Sparc) or patch 118855-16 (x86) to fix this issue.
Bug 6443017 - The UTM LUNs for the Sun StorageTek 6540 Array appear in the format command output. To avoid confusion, these LUNs should not appear in the output.
Workaround - In Solaris 8 and 9 OSs, the UTM LUN shows up under the SD driver. In Solaris 10 OS, for the Sun StorageTek 6540 Array, mask the LUN by adding the following entry into the /etc/driver_aliases file:
ses “scsiclass,00.vSTK.pUniversal_Xport”
This section provides useful operational information not documented elsewhere.
If you create management objects while an “import array” job is running, it might interfere with the import. Be sure that everyone who uses the destination array does not modify or create any objects (including volumes, initiators, mappings, and so on) while the import is in progress.
When you create a volume and label it, you can start using the volume before it is fully initialized.
During bootup, 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 by a timer approximately every 25 hours.
Each controller tray contains a hot-pluggable lithium ion battery pack for cache backup in case of power loss. The on-board battery is capable of holding a 2-GB cache for up to 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).
The Solaris data host format command might render one or more of the following listings:
STK-FLEXLINE380-0616 and STK-UniversalXport-0616
These are not data volumes and should be ignored.
The Sun StorageTek 6540 Array Site Preparation Guide (819-6524-nn) incorrectly cites the following information in Chapter 2 under cabinet Power Requirements:
This should state the following:
|
Four 20 Amp circuits are required for the 6540 cabinet to insure full redundancy. (UL allows the planned use of only 16A from each of those 20A circuits.) |
All components in the cabinet should operate on only two of the 20A circuits (16A loaded each), but in this case no AC redundancy would be in place (power only A0/A1 or B0/B1).
With all four 20A circuits powered (A0, A1, B0, B1), the cabinet will draw a maximum total of 32A from the four circuits. If the system were to draw more than that 32A, then full AC redundancy cannot be present.
The Sun Rack 1000-38 cabinet power distribution systems work at 180-264VAC only. Internal components will never be operated below 180V (200V nominal) when in this cabinet.
