HP P6000 Enterprise Virtual Array release notes (XCS 10001000) Abstract This document applies to the HP 4400 Enterprise Virtual Array, HP 6400 Enterprise Virtual Array, HP 8400 Enterprise Virtual Array, HP P6300 Enterprise Virtual Array, and HP P6500 Enterprise Virtual Array.

Version: XCS 10001000 Description The information presented within this document applies to the following array models: Array model Controller model Disk enclosure model HP 4400 Enterprise Virtual Array (EVA4400) HSV3001 or HSV300-S1 M6412 or M6412A HP 6400 Enterprise Virtual Array (EVA6400) HSV400 M6412A HP 8400 Enterprise Virtual Array (EVA8400) HSV450 M6412A 1 HP P6300 Enterprise Virtual Array (P6300 EVA) HSV340 M6612 (LFF) or M6625 (SFF) HP P6500 Enterprise Virtual Array (P6500 EVA) HSV36
Enhancements XCS 10001000 contains the same functionality as XCS10000000: • New racks, known as the “Intelligent Series Racks”, have been introduced, offering improved cable management and air flow. Related hardware documentation will be updated in the next release. • EVA management software support—HP Command View EVA 9.4 or later (both server-based management and array-based management) is supported with XCS 10001000.
Controller termination This section describes issues that can result in termination of controller operation. A single controller termination will result in a reduction of redundancy. A dual controller termination indicates a possibility of a data unavailable condition. A recursive termination will require manual intervention to address.
• Fixed an issue where a controller can experience a processor exception termination when two drive failures occur in a narrow window while executing a Vraid5 write with multiple failed drives. Fixed an issue that can result in a recursive controller termination (termination code 0x071a0100) or incomplete leveling activity under rare circumstances. • Fixed the cache prefetching algorithm to prevent multiple watchdog timer terminations (0x0420011f, 0x04800106) from occurring.
• Fixed an issue where back-end transport errors caused the controller software to fail a disk drive unnecessarily. • Fixed an issue where the array would not log any events to indicate the back-end disk enclosures were improperly cabled. • Fixed an issue where the I/O module firmware upgrade gets blocked when a disk enclosure disappears and then remains blocked when the enclosure is accessible again.
• Fixed an issue where a controller can experience a watchdog timeout termination during host port LUN processing. • Fixed an issue where 0x4207001b and 0x420d001b events were not being logged on EVA6400 and EVA8400 controllers. • Added event logging to increase visibility to host port Fibre Channel nameserver logins during DR tunnel creation. • Fixed a Direct Memory Access (DMA) error that occurred when an active controller was physically removed from an enclosure.
• Fixed an issue which causes a controller to experience a stalled state and execute a CSM Reset termination (termination code 0x4238011f) to clear the stalled state due to the tunnel state transitions not calling back the log for failed merge writes. • Fixed an issue where a controller experiences a processor exception termination due to a stack overflow on remote replication write retries when the SCSI-FCP tunnel is open, but the remote replication array discovery data is marked invalid.
Upgrades (controller software, I/O module firmware, disk drive firmware) This section describes issues affecting upgrades involving controller software, I/O module firmware, or disk drive firmware. • Fixed an issue where controllers do not shut down as intended following a situation where disk enclosures overheat and bypass drives. This issue can result in improper array start up, thereby leaving the array vulnerable to cache data loss conditions.
NOTE: For the EVA4400, HP Command View EVA 9.2 is pre-installed on the controller enclosure management module (for array-based management); on the P6300/P6500 EVA, HP P6000 Command View 9.4 is pre-installed. You can still use HP P6000 SmartStart to configure application servers. To bypass the HP P6000 SmartStart interface and manually run the HP P6000 Command View installer, go to the \bin\installers\CV directory on the CD.
Workarounds This section identifies important notes and workarounds for the EVA4400, EVA6400, and EVA8400. If you encounter difficulties with the workarounds, contact HP Services for assistance.
Symptoms of this issue are: • Data replication stops after the upgrade. • There are no visible paths to the destination array. To determine if there are visible paths, select the Data Replication folder in the HP P6000 Command View navigation pane. When the Data Replication Properties Folder window opens in the content pane, select View remote connections. To resolve this issue, you must set the protocol to HP FC Data Replication Protocol in HP P6000 Command View as follows: 1.
Windows 2003 server requires hotfix If the management server is running Microsoft Windows 2003, HP P6000 Command View may not display any array. To resolve this issue, you must install a Microsoft hotfix. Go to the following link for details and the hotfix download: http://support.microsoft.com/kb/945119 If you are using the server for storage only, not as a management server, you do not need to install this hotfix.
