HP 2000 Modular Smart Array Controller Firmware J202P01, J212P01, and J302P01 Release Notes (537811-008, December 2012)

Known issues and workarounds
This is a cumulative list of known issues and workarounds since the initial firmware release.
• How to get out of failure mode:
Pull host cables.1.
2. Power cycle raid-head enclosure.
3. After reboot, wait for disk lights to stop flashing as this indicates de-stage is complete.
4. Plug host cables back in and reconfigure the host to do I/O.
• SSH access to the MSA2000 CLI may fail on repetitive attempts to open and close the connection.
When using telnet and secure shell (SSH) to access the command line interface (CLI), the connection
may fail when multiple sequences or commands are sent from a script. The issue does not occur
if a delay, for example 0.25 to 1 second, is inserted between the ssh close and the subsequent
ssh open commands in the script.
• An initializing vdisk is accessible immediately, but is not fault tolerant.
The "Virtual Disk Initialization" section in the HP 2000 Family Modular Smart Array Reference
Guide states: "If the virtual disk is initializing online, you can start using it immediately," which
may be misleading. As shown in the "Virtual Disk Icons" section in the guide, the vdisk is NOT
fault tolerant while the vdisk is initializing or in a critical state.
• MPIO reporting path fail-over to single LUN on Windows Server 2008 host.
A Windows Server 2008 host may occasionally lose a single path to a single LUN. The Windows
2008 MPIO reports a path fail-over, however, the path may not come back. This issue is fixed
with Microsoft QFE KB957316, which is available from the Microsoft support website at http://
support.microsoft.com/kb/957316. Review the information and download the appropriate QFE
for the Windows Server 2008 operating system. If Microsoft QFE KB957316 is not installed, the
system must be rebooted to correct the issue.
• A failed drive may not be displayed on the Enclosure View page in the SMU.
Should this condition occur, check the drive LED indicator for a solid amber light indicating a
failed drive. If the drive was configured for SMART detection, check for entries in the array system
event log. Note: The failed drive status displays as Missing using the show disks encl command
from the command line interface (CLI).
• Removing all the drives from a JBOD enclosure causes the enclosure to be removed from the SMU
Enclosure View page.
To check the status of the enclosure, access the array using one of the command line interface
(CLI) methods and run the show enclosures command.
• Windows Server 2003 SP2 fails to hibernate causing the system to lock up.
Applying Microsoft hot fix KB940467 corrects the issue for Windows Server 2003 SP2.
To obtain KB940467 from the HP website:
1. Go to http://www.hp.com/support/storage.
2. In the Disk Storage Systems section, select MSA Disk Arrays.
3. Select your product.
4. Select Download drivers and software.
5. Select your product.
6. Select your Windows Server 2003 operating system.
7. In the Operating System — Enhancements and QFEs section, select the KB940467 QFE.
• I/O may not resume to SUSE and Red Hat Linux hosts upon cable reinsertion.
The likelihood of this issue occurring increases with the number of LUNs configured on the storage
array and load. The failover/failback process is working correctly at the multipath driver level.
