Before replacing a failed disk, note its Device Special File (DSF) information.
If you shut down a server to replace a failed disk offline, the DSF of the failed disk is not
visible in the ioscan utility when the server restarts. The DSF is required by the
replace_tgt command to rebuild the array with the new disk.
Corrective Action: Before you shut down the server, run the ioscan utility and note the
DSF information for the failed disk.
For more information on replacing disks, see the HP 8 Internal Port SAS Controller and HP
Multi-Port Internal SAS Controller Support Guide at:

4.2 AH303A PCIe SC44Ge SAS Host Bus Adapter
•
Virtual Partitions do not boot in multi-initiator configurations.
Virtual Partitions (vPars) using an HP StorageWorks MSA60 or MSA70 enclosure does not
boot if AH303A cards assigned to multiple virtual partitions are connected to the same JBOD.
Under the vPars I/O resource assignment rules, a host bus adapter cannot be shared among
multiple virtual partitions.
Corrective Action: None. This issue is corrected in vPars A.05.03 (B.11.31.0803).
•
There is a setboot command issue on specific servers.
The setboot -p/-a/-h command fails when issued on an AH303A adapter installed in
slots 3 or 4 on HP Integrity rx3600 and rx6600 systems.
Corrective Action: Install AH303A adapters in nonswitched slots. This issue is corrected in
patch PHKL_37278.

Unnecessary reboot occurs when removing the sasd driver.
If you use swremove to remove the dynamically loaded sasd driver, the Critical Resource
Analysis (CRA) can fail. This causes the swremove command to incorrectly reboot the
system.
Severity: Low
Corrective Action: To avoid this CRA failure, before running swremove install patch
PHCO_36356 (or a superseding patch). Patches are available from the HP IT Resource Center
at:
http://itrc.hp.com/
Under “Maintenance and Support,” click the Patch Database link, then search for the patch
number. For more information on how to manage and install patches, see the Patch
