Facilità d'uso
4.1 For all Smart Array controllers
•
A newly-created logical volume might not be available.
When you create a new logical volume on a Smart Array controller, you must run the ioscan
command to make the volume available for use.
•
Unnecessary reboot occurs when removing the ciss driver.
If you use the swremove command 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://www.hp.com/go/hpux-core-docs.
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 is not detected.
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 SAS (Serial-Attached SCSI) Smart Array controllers
•
SATA disks are not supported when the controller is in HBA mode.
•
New Smart Array P700m controller installations should be on HP-UX 11i v3 March 2010
release or later.
If you are considering a new installation of an HP Smart Array P700m Controller, HP
recommends that you configure it on HP-UX 11i v3 March 2010 release or later.
New installation of a P700m controller is not recommended on HP-UX 11i v3 releases prior
to March 2010. HP-UX 11i v3 releases prior to March 2010 might not guarantee that P700m
Device Special Files (DSFs) persist between releases. This can cause data on arrays to become
unavailable when you upgrade to the March 2010 (or later) release of HP-UX 11i v3.
•
SAS Storage Enclosure Status display issue in sautil command output.
SAS storage enclosures (SES devices) and their status appear in the outputs of sautil
/dev/cissX (extensive output) or sautil /dev/cissX -s (shortened output) commands.
Devices appear in the SAS/SATA DEVICE SUMMARY section, and in the detailed information
provided for each DISK device and SES device in the command output.
The status of a SAS SES device is always FAILED. The FAILED status does not indicate that the
enclosure is not functioning. It means that it is not a DISK device.
Corrective Action: None. You can continue to use the SAS storage enclosures. You can also
use sautil to download enclosure firmware when needed.
