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.
For more information, see the HP Smart Array SAS Controllers for Integrity Servers Support
Guide at http://www.hp.com/go/smart-array-raid-docs.
•
HP-UX installation fails.
Installation of HP-UX 11i v3 fails when installing to an array of eight 146 GB SAS disks
configured as a single RAID 0 logical volume.
Corrective Actions:
◦
Option 1: Install patch PHCO_36555. 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
◦
Option 2: Reconfigure the RAID 0 logical drive to use seven or fewer 146 GB disks.
4.3 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.
