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.
For more information on replacing disks, see the HP 8 Internal Port SAS Controller and HP
Multi-Port Internal SAS Controller Support Guide at:
