Dell EqualLogic PS Series Storage Arrays

Firmware Version 9.1.9 Release Notes

This document describes important product information and restrictions for Dell EqualLogic PS Series storage arrays running PS Series

firmware version 9.1. This version of the firmware includes all corrections and enhancements made in prior releases. Unless otherwise

noted, all information in this document applies to version 9.1 of the PS Series storage arrays and all future maintenance releases for version

9.1

CAUTION: Do not convert the initial RAID policy in a PS4210, PS6210, or PS6610 array until you have updated to the General

Availability version of 9.1. RAID policy conversion while running the early (EPA) version of 9.1 might result later in user data

inconsistency and/or failure of controller redundancy.

Additional Access for Pool Administrator and Read-Only Accounts Group Manager now contains new access options for pool administrators with group read permissions. When you create or modify an administrator account, you can select a check box under Account Permissions > Additional Access that enables access to save diagnostics and save configuration. When this feature is enabled, the menu option to collect diagnostics is made available for the user.

Reverting from version 9.1.6 or later to a version earlier than 9.1.6 is not supported. If you want to revert to an earlier version, contact your technical support provider. I/Os Might Fail During a Firmware Update if Members Have Type 7 or Type 10 Controllers In the Group Members with Type 7 or Type 10 controllers in the group show high latency during firmware updates, which can lead to I/O failures. Updating FluidFS Series v3.0+ to v4.0 Fails When Using PS Series v9.1 If the PS Series array is running v8.
PAGE 11
Discrepancy In Replica Count After Performing Promote and Failback to Primary While performing a PS to SC replication, during the DR activation (failover) and failback, Group Manager displays the replica count incorrectly. This replica count issue does not impact the replication process.
PAGE 12
You can run multiple instances of the Group Manager GUI in separate tabs. When running multiple GUI instances, Dell recommends that you launch the GUI instances one at a time to avoid scenarios in which multiple login dialog boxes are displayed at the same time. Otherwise, the Java virtual machine might become unresponsive and the browser application must be restarted. In Firefox, you can run only one instance of Group Manager in a browser window.
PAGE 13
When you move delegated space from one pool to another pool for a partner, the pool mapping entry (if any) does not automatically get updated. You must manually change the pool mapping. Issues Corrected in Version 9.1.9 This version of PS Series firmware includes all the fixed issues that were incorporated into earlier releases. Hardware • Dell may dispatch 4Kn drives as replacement drives for PS Series arrays with 512n drives. PS Series firmware version 9.1.
PAGE 14
• • • • • During a Storage Center (SC) to Peer Storage (PS) volume replication, an SC controller failover resulted in a discrepancy in replicated volume data. After a RAID expansion or an interrupted RAID configuration during setup, the array rebooted. In rare circumstances, a PS65x0 array rebooted due to disk structure deficiency. Cross-platform replications were stopping every 6-8weeks. Support needed to reset iSCSI ports to restart cross-platform replications.
PAGE 15
• Under extremely rare circumstances, a PS6510 array lacked passive control module redundancy, but firmware allowed user to failover. Firmware now warns instead with a message similar to Restart aborted by firmware: cannot proceed due to detected redundancy loss issue on the passive controller. Install/Updates • • [CRITICAL] A change of behavior was introduced with version 9.1.x that resulted in the array being set offline when a volume was detected to have missing pages. Version 9.1.
PAGE 16
• False positive temperature warnings were received through the SNMP reporting program. Replication • • • During synchronous replication, the host sent unaligned data packets after a write command, which led to a failover. A timeout issue occurred while replication cleanup was in progress. This issue prevented all future replication operations from starting.
