Table 7 HP-UX 11i v3 March 2009 fixes RAID-01 B.11.31.0903 SR Number QXCR1000875017 The sautil utility does not display interrupt statistics when using the stat option. There were no defects or fixes included in RAID-01 version B.11.31.0809. 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 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. 6

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 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. Special considerations apply when upgrading a server with an MSA2300 Series enclosure to HP-UX 11i v3 Application Release 0909. HP-UX 11i v3 Application Release 0909 (AR0909) contains the RAID-01 B.11.31.0903 bundle. Servers with an MSA2300 Series enclosure as part of the configuration have RAID-01 version B.11.31.0906 installed. Updating the server with update-ux will not downgrade the RAID-01 driver, but running AR0909 with RAID-01 B.11.31.0906 is not a supported configuration. To run AR0909 on a server with an MSA2300 enclosure, you must install the RAID-01 B.11.31.0909 bundle after updating the operating system. The 11.31.0909 bundle will be available as a web release on the HP Software Depot website in September 2009. RAID-01 11.31.0909 provides support for HP StorageWorks MSA2300 Series enclosures, and defect fixes. No special considerations apply when upgrading servers that are not configured with an MSA2300 Series enclosure to AR0909. You can download the RAID-01 B.11.31.0909 bundle from the HP website at: http://www.hp.com/go/softwaredepot Search for RAID-01. Special considerations apply when performing a clean installation of HP-UX 11i v3 Application Release 0909 on a server configured with an MSA2300 Series enclosure. HP-UX 11i v3 Application Release 0909 (AR0909) contains the RAID-01 B.11.31.0903 bundle. Servers configured with an MSA2300 Series enclosure require RAID-01 version B.11.31.0906. Performing a clean installation of AR0909 on a server with an MSA2300 Series enclosure connected will cause a system panic. To perform a clean installation of AR0909 on a server with an MSA2300 Series enclosure, follow these steps: 1. Power off the system. 2. Disconnect the MSA2300 Series enclosure. 3. Power on the system. 4. Install HP-UX 11i v3, Application Release 0909. 5. Install RAID-01 B.11.31.0909. 6. Connect the MSA2300 Series enclosure. No special considerations apply when performing a clean installation of AR0909 on servers that are not configured with an MSA2300 Series enclosure to AR0909. You can download the RAID-01 B.11.31.0909 bundle from the HP website at: http://www.hp.com/go/softwaredepot Search for RAID-01. 4 Known problems and limitations 7

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 P400 and P800 Controller Support Guide at: http://www.hp.com/go/hpux-iocards-docs Click the link for your HP-UX version. Support guides are listed alphabetically in the User guide section. 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. Corrective Action: Reconnect the cables or reinsert the disks, then reset the Smart Array controller using the sautil reset_ctlr command. After the controller is reset, ioscan correctly reports the status of the disks as CLAIMED. Disconnected external storage enclosures are not properly detected by ioscan. If you disconnect all cables connecting a Smart Array controller to external storage enclosures, saconfig and sautil show the status of the logical drives as FAILED. However, ioscan continues to report the status of the disks as CLAIMED. Corrective Action: Reset the Smart Array controller using the sautil reset_ctlr command. When the controller is reset, ioscan correctly reports the status of the disks as NO_HW. Controller fails when two connectors are used on the same channel. Each channel has two connectors (one internal and one external), but only one connector can be used per channel at any given time. If you attempt to boot the system with storage devices connected to the internal and external connectors on the same channel, the controller fails. 8

Corrective Action: Shut down and power off the system, fix the cabling issue, and power on the system. 5 Compatibility and installation requirements This section describes the compatibility information and installation requirements for this release.
