Patch Name: PHKL_8908 Patch Description: s700 10.20 HSC/GSC+/WSIO SCSI Patch Creation Date: 96/12/06 Post Date: 96/12/06 Repost: 97/01/09 The patch documentation was modified to remove references to the s800 equivalent patches: PHKL_8905, PHKL_8907, and PHKL_8909. The problem addressed by this patch does not affect the s800 platform so these patches will not be released. Hardware Platforms - OS Releases: s700: 10.20 Products: N/A Filesets: OS-Core.CORE-KRN Automatic Reboot?: Yes Status: General Superseded Critical: Yes PHKL_8908: PANIC CORRUPTION Panic should occur only if root volume is LVM on built-in SCSI in 710, 720, 715/50, 725/50. Corruption should only occur on QUANTUM LPS525S on built-in SCSI in 710, 720, 715/50, 725/50. PHKL_8187: HANG PHKL_7987: HANG Path Name: /hp-ux_patches/s700/10.X/PHKL_8908 Symptoms: PHKL_8908: "SCSI: Unhandled interrupt" and resulting bus reset can cause panic during boot of 710, 715/50, 720 and 725/50 workstations if root disk is LVM and on built-in SCSI bus. It's theoretically possible for the bus reset to cause data corruption on QUANTUM LPS525S disks on the bus. Some M/O drives will not work on the above systems plus 705, 715/33, 730, 735 and 755. PHKL_8187: Select timeouts are retried forever, i.e. I/O's never complete when a device is removed. SCSI bus hang and reset. PHKL_7987: System hang. Select timeouts with EMC/Symmetrix disk array. Defect Description: PHKL_8908: The c720 driver does not lisc->sclk soon enough. Chip timing parameters are set up incorrectly. PHKL_8187: Select timeouts are retried forever. B_NDELAY should eliminate retries on select timeout. Zalon chip bug results in SCSI bus hang. PHKL_7987: Bug in scsi_schedule_retry causes hang. 10 ms select timeout period is too short.

Back up your system before installing a patch. 2. Login as root. 3. Copy the patch to the /tmp directory. 4. Move to the /tmp directory and unshar the patch: cd /tmp sh PHKL_8908 5a. For a standalone system, run swinstall to install the patch: swinstall -x autoreboot=true -x match_target=true \ -s /tmp/PHKL_8908.depot 5b. For a homogeneous NFS Diskless cluster run swcluster on the server to install the patch on the server and the clients: swcluster -i -b This will invoke swcluster in the interactive mode and force all clients to be shut down. WARNING: All cluster clients must be shut down prior to the patch installation. Installing the patch while the clients are booted is unsupported and can lead to serious problems. The swcluster command will invoke an swinstall session in which you must specify: alternate root path - default is /export/shared_root/OS_700 source depot path - /tmp/PHKL_8908.depot To complete the installation, select the patch by choosing "Actions -> Match What Target Has" and then "Actions -> Install" from the Menubar. 5c. For a heterogeneous NFS Diskless cluster: - run swinstall on the server as in step 5a to install the patch on the cluster server. - run swcluster on the server as in step 5b to install the patch on the cluster clients. By default swinstall will archive the original software in /var/adm/sw/patch/PHKL_8908. If you do not wish to retain a copy of the original software, you can create an empty file named /var/adm/sw/patch/PATCH_NOSAVE. Warning: If this file exists when a patch is installed, the patch cannot be deinstalled. Please be careful when using this feature. It is recommended that you move the PHKL_8908.text file to /var/adm/sw/patch for future reference. To put this patch on a magnetic tape and install from the tape drive, use the command: dd if=/tmp/PHKL_8908.depot of=/dev/rmt/0m bs=2k Special Installation Instructions: None
