Restrictions and Known Issues

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

• Installation and Initial Configuration Issues
• Hardware and Firmware Issues
• Documentation Issues
• Operational Information

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

Installation and Initial Configuration Issues

This section describes known issues and bugs related to installing and initially configuring the Sun StorageTek 6140 Array.

Single Path Data Connections

In a single path data connection, a group of heterogeneous servers is connected to an array through a single connection. Although this connection is technically possible, there is no redundancy, and a connection failure will result in loss of access to the array.

Caution - Because of the single point of failure, single path data connections are not recommended.

Auto-Negotiation of Ethernet Switches Must be Set to On

Bug 6538927 - The Ethernet ports of the array auto-negotiate for standard 10 and 100 Mbits/second full duplex connectivity. The Ethernet switch that the array’s management path connects with must have auto-negotiation turned on. If it is not set, the array will eventually lose visibility from the management host.

Hardware and Firmware Issues

This section describes general issues related to the Sun StorageTek 6140 Array hardware and firmware.

Expansion Tray Requirements

When you add a new expansion tray to an existing array in a production or active environment, you must cable and add the trays while the RAID controller module is powered on.

Failed Drive Maintenance LED Remains Illuminated After Volume Deletion

Bug 6590564 - When a drive has failed and is part of a volume being deleted, it is possible for the failed drive’s blue maintenance LED to illuminate and remain illuminated despite the drive no longer being assigned to a volume.

Workaround - A reboot of the controller will clear the maintenance LED.

Cannot Boot From System With a 6768A Direct Attached HBA

Bug 6358173 - The 6768A (QLogic 2342) 2-Gb dual-port adapter cannot be used in direct attach mode, and you cannot boot from it.

Workaround - To use 6768A in direct attach mode, move the jumpers from pins 2-3 to pins 1-2. To boot using this HBA, move the 6768A jumpers from pins 2-3 to pins 1-2 or put a switch between the host and array.

Errors From Expansion Tray 2A and 2B Ports

Bug 6417872 - When Small Form-factor Plugs (SFPs) are installed in ports 2A and 2B of an expansion tray, the front amber fault LED turns on and the IOM displays an H8 error.

Workaround - Do not install SFPs into these slots.

Documentation Issues

This section describes known issues and bugs related to the Sun StorageTek 6140 Array documentation.

Installation Documentation Correction Regarding Sun Cluster Support

The note on page 77 of the Sun StorageTek 6140 Array Hardware Installation Guide, p/n 817-7497, incorrectly states the configuration in Figure 3-4 is not supported for use in a Sun Cluster environment.

Correction--Change the text of the note to read:

Reset Battery Age Procedure Omitted from Guide

Bug 6887119--The Sun Storage 6000 Series Hardware Upgrade Guide, p/n 820-7003-10, is missing a step for resetting the battery age.

Correction--After installing the new controller tray and reconnecting the cables, use the Service Advisor Battery Replacement procedure to reset the battery age.

Cable Changes in Installation Guide

The Sun StorageTek 6140 Array Hardware Installation Guide has not yet been updated for:

• The addition of one RJ45-DB9 adapter with null modem to the contents of the controller tray box.
• A change from copper cables to 2-meter optical FC cables and SFPs in the expansion module box.

Operational Information

This section provides useful operational information not documented elsewhere.

Sharp Edges on Chassis

Caution - On both the controller and expansion trays, the rear of the chassis has very sharp edges.

Controller FRU Handle Can Be Hazardous

Caution - Be careful using the FRU handle on the controller tray. It can snap shut when pushed hard during reinsertion, pinning fingers between the tray and handle edges.

Replacing Failed Disk Drives From Another Array

If a volume failure on a Sun StorageTek 6140 Array results from failed disk drives, you must be careful when introducing replacement drives that were part of a volume in use by another Sun StorageTek 6140 Array.

Workaround - To avoid having the array incorrectly initiate a volume migration process with the newly introduced replacement drives, perform one of the following tasks:

• Verify that the volume on the Sun StorageTek 6140 Array with the failed disk drives has not been deleted. You should leave the volume in a failed state and not delete the volume.
• Verify that the disk drives being taken from the inactive Sun StorageTek 6140 Array are not part of an active volume. If the disk drives are part of an active virtual disk, delete all volumes residing on that virtual disk before removing the disk drives.

Controller Tray ID Numbering Is Unrestricted

Controller tray IDs can be set to any number between 0 and 99. 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.

The Expansion Module Must Be Set to the Same Interface Speed As the Controller

The controller and expansion modules must be set to the same interface speed. If the 2/4Gb switch is set to 2Gb on one and it is set to 4Gb on the other, the expansion module will appear inoperative with no indication of the cause.

The controller is set to 2Gb at the factory. An expansion module is set at the factory to whatever its disk drives are. You can determine the interface speed of the disks in the tray by removing one of the disks and examining the label. Next to the disk name on the label there is a number indicating the spindle speed and interface speed of the disk. For example, the number 15k.4 indicates the disk is 15,000 RPMs and 4Gb.

Cable Adapters

The array ships with two RJ-45 to miniDIN cables, a RJ45-DB9 adapter, and a RJ45-DB9 adapter with a null modem. The two adapters allow users to connect to the array from most Sun workstations, portable PCs, and terminal servers. If your ship kit does not include the RJ45-DB9 adapter with a null modem and you cannot connect with the RJ45-DB9 adapter, either supply your own adapter or contact Sun Service.

To connect from a portable PC without a serial port, you will need to purchase a USB to serial adapter, available from most computer stores.

When Performing an Array Import, Do Not Modify Management Objects

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.

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 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 approximately every 25 hours by a timer.

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-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).

Status Codes

The following is a list of the meanings of the status and diagnostic codes that may display on the numerical LEDs on the controller and expansion modules.
