New Features in This Release

This release includes new versions of RAID controller firmware and related enclosure firmware, Sun StorEdge Configuration Service, Sun StorEdge Command-Line Interface (CLI), and Sun StorEdge Diagnostic Reporter. It incorporates requested enhancements as well as fixes to previously known issues.

Note - The Sun StorEdge 3000 Family of storage products, including the Sun StorEdge 3510 FC array and the Sun StorEdge 3511 SATA array, are now referred to as Sun StorageTek storage products. These are identical products. To avoid confusion, the manuals for these products will retain the old Sun StorEdge designation.

New Instructions for Migrating From RAID Controller Firmware 3.2x to 4.x

The RAID controller firmware upgrade procedure has been streamlined and simplified, and additional logging capabilities have been added to the upgrade script. Refer to the Sun StorEdge 3000 Family RAID Controller Firmware Migration Guide , 819-6573, for step-by-step procedures for upgrading RAID controller firmware version 3.2x to version 4.x.

Caution - These procedures must be followed when performing this major upgrade. Minor upgrades from earlier versions of 4.1x firmware do not require the use of this document and can be performed by following the instructions in the firmware patch README file.

Current NVRAM Version Displayed

The RAID controller’s firmware now displays the current NVRAM version installed on the controller in the View System Information window. This helps diagnose any conflicts that might have occurred if a controller was replaced or new firmware installed without resetting NVRAM. Refer to the Sun StorEdge 3000 Family RAID Firmware 4.2x User’s Guide, 817-3711, for instructions on how to use this feature.

Recently Added Clear Core Dump Firmware Menu Option

RAID controller firmware versions 4.23 and beyond include a Clear Core Dump firmware option on the system Functions menu.

In a redundant controller configuration, if an unrecoverable error condition occurs, the affected controller might write debug information to NVRAM. If this happens, an event message will be displayed each time the controller reboots, such as the following:

ALERT: Controller Unrecoverable Error 0001 00000000 00000000 45754677

This message is displayed each time a failed controller is restarted after a redundant controller failure and does not indicate a new controller failure. The date and time of the event message indicates the time the controller was restarted, not the time of the failure.

If the unrecoverable error recurs, clear the core dump only on the advice of your support representative.

Refer to the “System Functions” chapter and “Event Messages” appendix of the Sun StorEdge 3000 Family RAID Firmware 4.2x User’s Guide, 817-3711, for details about clearing core dumps and about unrecoverable error messages.

Consequences of Unsupported Configurations Minimized When Using More Than One Sun StorEdge Configuration Service Monitor Console (ssmon)

Sun StorEdge Configuration Service uses a distributed architecture to monitor RAID arrays. One--and only one--Configuration Service console, a process called ssmon running on a host, gathers information from the array to which it is connected. Up to ten Configuration Service agents communicate this information as needed. Running more than one Configuration Service console is not supported. In previous releases, doing so could cause data loss.

Previous Feature Changes in 4.1x RAID Controller Firmware and 2.x Software

A number of firmware and software changes occurred when RAID controller firmware 4.11 was introduced; they apply to all firmware 4.x versions. TABLE 1 describes these changes.

Performance Implications of Migrating to Firmware Version 4.x

Sun has made changes to the firmware for the StorEdge 3310 and 351x arrays between versions 3.2x and 4.x that can impact performance. The algorithm for aggregating small writes in the cache has been improved so that they can be written to disk at the same time. This results in improved performance under workloads that issue mostly small sequential writes, or many small random writes within the same region. The performance improvement is most dramatic under workloads that queue many commands to the array, giving it the most opportunities to aggregate writes. Users should tune their applications and host driver stacks to queue up to 32 commands whenever possible.

Sun has also added increased error and data integrity checking to firmware 4.11 and later versions that can have an adverse affect on performance for StorEdge 33x0 and 351x arrays when upgrading from firmware version 3.2x. Users might experience a decrease in performance under workloads that primarily issue sequential reads. To mitigate this impact, tune applications and host driver stacks to issue the largest reads and maintain the highest queue depths possible.

Users may also see a small performance decrease under workloads that primarily issue large sequential writes. These users should also tune their host to issue the largest writes possible and maintain a large command queue depth.

Firmware and software changes between 4.15 and 4.2x have no significant impact on performance.

Using cache write-through mode rather than write-back mode can have a significant impact on performance. To ensure that write-back cache is enabled for all LUNs after upgrading RAID controller firmware, from the RAID controller firmware Main Menu choose “view and edit Configuration parameters > Caching Parameters > Write-Back Cache.” If it is disabled, choose 'Yes' to change the setting to Enabled.

Additional safety checks have been added to the 4.x firmware that will disable write-back cache and change the cache to write-through mode under certain error conditions. Conditions that can cause the array to switch to write-through mode include:

• Battery backup failure
• AC power loss
• Fan failure
• Power supply failure
• High temperature in CPU/Enclosure
• Failure of a redundant controller

Once the condition is corrected, write-back cache is automatically re-enabled.

In firmware versions 4.11 and later, these triggering events can be enabled or disabled, and the threshold limits can be set, using the RAID controller firmware’s Main Menu. For more information about write-back cache, refer to Chapter 11, “Configuration Parameters,” in the Sun StorEdge 3000 Family RAID Firmware 4.2x User's Guide.

Optimization Mode and Stripe Size Features

The optimization mode in firmware version 4.x controls cache block size only. This is a significant improvement in functionality and performance over earlier 3.x firmware, where the optimization mode chosen also determined stripe size for all logical drives.

With firmware version 4.x, when you specify sequential or random cache optimization, the controller determines and specifies a default stripe size for newly-created logical drives. However, you can specify a stripe size for each logical drive when you create it, enabling you to maximize performance by matching stripe size with your application requirements. Since different applications can use different logical drives, this functionality provides you with greatly increased flexibility.

Because of this, sequential optimization, which is the default, is almost always the best optimization choice. You should use random optimization only when performance testing in your production environment demonstrates improvement over the default sequential optimization.

For sequential optimization, the cache block size is 128 Kbyte. Available stripe size options include 16 Kbyte, 32 Kbyte, 64 Kbyte, 128 Kbyte, and 256 Kbyte. The default stripe size for sequential optimization is 128 Kbyte for all logical drives except RAID 3, which is 16 Kbyte.

For random optimization, the cache block size is 32 Kbyte. Available stripe size options include 4 Kbyte, 8 Kbyte, 16 Kbyte, 32 Kbyte, 64 Kbyte, 128 Kbyte, and 256 Kbyte. The default stripe size for random optimization is 32 Kbyte for all logical drives except RAID 3, which is 4 Kbyte.

With firmware version 4.x, you can also specify a cache write policy for each individual logical drive, giving you further opportunities for performance tuning.

The following table summarizes the functionality described above:

Known Issues

• CR 6357118: Controller should not mark disks as “bad” after FC errors on one drive channel (loop). In RAID controller firmware 4.21, under certain error conditions the controller firmware can declare disk drives bad and remove them from a RAID volume, resulting in an unnecessary RAID reconstruct and unnecessary disk replacement. This occurs when the controller is unable to identify a few back-end FC communication error conditions and therefore does not failover to the alternate channel. In an extreme case, this can cause multiple disks to be reported as “bad,” which can cause the logical drive to go offline, reported as a “fatal fail.” When the logical drive is failed, unwritten data is purged from cache without being written to media.
  The controller interacts with drives through a redundant back-end fiber channel arbitrary loop. In rare circumstances, a failing component or bad connection on the back-end Fibre Channel loop--such as bad SFPs or bad cables or bad drives--might result in the controller being unable to communicate with some of the drives on one of the channels. Prior to this release, no firmware logic was available to try alternative drive channels if communication through the current drive channel was unsuccessful. In this release, an alternate drive channel is used when one of the drive channel goes bad.
  Workaround: Use the firmware Main Menu to bring the logical drive back online manually. If multiple disks were marked as “bad” and removed from a logical drive by the controller, contact your technical support organization. Have them help identify the cause of the multiple disk failures and provide the necessary actions to rectify the error condition before attempting to reconstruct the logical drive to the state where the error occurred. Since some data might have been lost from the controller's write cache, check the validity of the data on the logical drive after reconstructing it. Successful reconstruction is not guaranteed.
• CR 6890196: Request to document "0" value for Maximum Drive Capacity in serial port menu. Logical drives can be created using either the firmware main menu or the CLI command line interface. Both interfaces enable you to specify a Maximum Drive Capacity if you want to use less than the full capacity of the physical drives in the logical drive. Otherwise, the default is to use the entire available capacity. However, due to a difference in the methods used by the two interfaces, a small size difference can exist between their default sizes. This can cause discrepancies when a logical drive created using one interface is mirrored or recreated using the other interface. This is true for all Sun StorageTek 3000 family RAID controllers since they share the same firmware and software interfaces.
  Workaround: When using the firmware to create a logical drive that uses the full capacity of the physical drives that comprise it, do not accept the default. Instead, specify a Maximum Drive Capacity of 0. This ensures that the resulting logical drive size will be identical with one created using the CLI and accepting the default drive size.

Known Issues Specific to Sun StorEdge 3511 SATA Arrays

• CR 6433420: Mailbox or IOCB interrupt timeout occurred after reset-all with PCI-X HBAs.When testing a V215 server attached to a Sun StorEdge 3511 with expansion unit, issuing a probe-scsi-all command at the OBP prompt caused the server to hang with this error message:
  Mailbox or IOCB interrupt timeout occurred.
  Non recoverable Error: Aborting QLA2422 driver execution (4000 )(0 )(ff00 )(0 )(0 )(0 )(0 )(0 )
  This issue appears to be specific to certain HBAs.
  Workaround: To recover from the hang condition, issue a break sequence and then issue a reset-all command at the OBP prompt prior to a probe-scsi-all command. To prevent this issue from recurring, ensure your HBA is running the latest available firmware and fcode.
