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

At the multipath application level, multipath maps are not getting updated. To update the maps
at application level, run the command multipath -v0. This command may take a few minutes
with heavy I/O running on the system.
• Windows Server 2003 host may hang after failure of a vdisk.
The start menu bar goes away, applications may become slow to close, and the system does not
reboot (shuts down all programs and closes network connections but hangs at gray screen with
mouse cursor still active). Microsoft is working on a QFE hotfix. Power cycling the host corrects
the issue.
• Installing the latest driver in RHEL5.2 with HP Device Mapper (HPDM) and Boot from Storage
configuration may stop the OS from booting.
After installing the 4.00.13.04-2 driver in a boot from storage configuration with HPDM enabled,
the RHEL 5.2 host may no longer boot into the operating system. HP is working on the issue.
Changing to the previous driver (for example, older INITRD) allows the host to boot from storage.
• After a cable move, LSI Logic MPT SAS BIOS loads incorrectly, showing initialization twice on
the server.
After moving SAS cables to a different SAS host bus adapter (HBA) on the server, the MPT SAS
BIOS may incorrectly load and initialize SAS HBA cards, after which the MSA2012sa stops
accepting I/O requests from the server. Use the SMU to reset the host port interface on both
MSA2012sa storage controllers. Log into the SMU and navigate to the Manage > Utilities > host
utilities > reset host channel page and click the Reset Host Port button to initiate the action. Although
the web page returns immediately with a response, it may take up to 1 minute for the MSA2012sa
storage controller to process the request and make the host ports ready for initialization by the
SAS HBA card. A reboot of the server is not required.
• An unanticipated path change may occur on Red Hat Linux 4 Update 6 hosts using HPDM Multipath
software.
In a multi-path configuration using HPDM software during periods of heavy I/O load, Linux Red
Hat 4.6 hosts may experience unanticipated path change due to a SCSI I/O timeout. This issue
does not occur for single path configurations. To reduce the likelihood of occurrence, ensure the
storage array is properly configured and has a balanced I/O load.
• Drives may not be seen by the LSI Logic MPT SAS BIOS when more than one SAS HBA card is
installed on some servers.
After making some configuration changes, the MPT SAS BIOS may not list all available drives for
boot during startup. This message may appear during startup: Adapter configuration may
have changed, reconfiguration is suggested. The MPT SAS BIOS setup utility,
accessed by pressing F8 during boot-up and selecting the SAS Configuration Tool, can be used
to add the HBA back to the boot list. A reboot of the server is required.
• A newly created snapshot volume on a single controller array presented and mapped to a Windows
host may not be detected by the Windows operating system.
Use the Rescan Disks command in Windows Disk Management to force detection of the newly
created snap shot volume. Rescanning disks can take several minutes, depending on the number
of hardware devices installed.
• The SMU may hang after drive failures.
If this condition occurs, access the array using the command line interface (CLI) and restart the
management controller (MC) using the command: restart mc a (single controller) or restart
mc both (dual controller).
