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 For All Smart Array Controllers

• Unnecessary reboot when removing the ciss driver.

If you use swremove to remove the dynamically loaded ciss driver, the Critical Resource

Analysis (CRA) can fail. This causes swremove 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

Management User Guide for HP-UX 11.x Systems at:

http://docs.hp.com/en/oshpux11iv3.html

NOTE: If you remove the dynamically-loaded ciss driver while it is in use, or if you remove

the statically-loaded ciss driver at any time, you must perform a reboot. This is normal

behavior under these conditions, and is not affected by patch PHCO_36356.

• Automatic hot-plug issue.

The HP Smart Array Controllers do not automatically detect the hot-plug of internal disks.

Corrective Action: After replacing a physical disk, run the sautil command with the scan

option.

4.2 For Parallel SCSI Smart Array Controllers

• Partially disconnected disks and external cables are not properly detected by ioscan.

If you remove all but one cable connecting external storage enclosures, or if you remove

physical disks that are part of a logical drive from the enclosures, saconfig and sautil

show the status of the logical drive as FAILED. However, ioscan reports the status of the

disks incorrectly.
