4 Known Problems and Limitations

This section provides a list of problems and limitations known to HP when these release notes

were published. If workarounds are available, they are included.

4.1 HP 8 Internal Port SAS Controller and HP Multi-Port Internal SAS Controller

• Updating the adapter firmware to version 1.23.33 or later might change the target ID of

disk devices.

This occurs on HP Integrity rx2660, rx3600, and rx6600 servers when an Integrated RAID

volume is configured on the controller and you perform one of the following actions:

— Update the adapter firmware offline using sasflash.efi.

— Boot to an HP-UX or Ignite-UX disk containing the sasd driver from one of the following

releases, which download firmware version 1.23.33 to the adapter during boot:

◦ B.11.23.0712

◦ B.11.31.0712

Changing the target ID might cause physical disks, including the OS boot disk, to become

inaccessible. If some of the disks from the IR volume are inaccessible, the volume can become

degraded or fail.

NOTE: The target ID change does not occur on systems without a RAID-1 volume. It also

does not occur on HP Integrity Bl860c servers with the HP Multiport SAS Controller.

For detailed information on how to avoid or correct this problem, see Updating Internal SAS

Controller Firmware to Version 1.23.33 Or Later at:

• 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 ioscan 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 ioscan and note the DSF

information for the failed disk.

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 under vPars A.4.05.

Virtual Partitions (vPars) version A.4.05 using an HP StorageWorks MSA60 or MSA70

enclosure do 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.
