Patch Name: PHKL_8906 Patch Description: s700 10.10 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 add Equivalent Patch information. Hardware Platforms - OS Releases: s700: 10.10 Products: N/A Filesets: OS-Core.CORE-KRN Automatic Reboot?: Yes Status: General Superseded Critical: No (superseded patches were critical) PHKL_8359: HANG PHKL_7090: PANIC HANG Path Name: /hp-ux_patches/s700/10.X/PHKL_8906 Symptoms: PHKL_8906: "SCSI: Unhandled interrupt" and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_8359: Select timeouts are retried forever, i.e. I/O's never complete when a device is removed. SCSI bus hang and reset. PHKL_7637: Too long request timeout, 2 min. 30 sec. on EISA SCSI. Missing SIOC_ABORT and SIOC_RESET_DEV functionality. Mediainit failure. PHKL_7090: panic: (display==0xb800, flags==0x0) Data page fault panic: (display==0xbf00, flags==0x0) Non-access data TLB miss panic: callout table overflow System hang with empty CD-ROM drive in /etc/fstab. Mediainit fails after two hours. Autochanger devices don't show up in ioscan output. SCSI_DISK2 doesn't work with unmounted QUANTUM PD* disks. (note: it isn't expected to work with mounted ones) TEAC floppy driver doesn't identify 5.25" 360K format. Ioscan shows incorrect s/w, h/w status for sctl driver. Bus hang resets or worse with QUANTUM PD* disks. Bus hang resets with Quantum VP3215 disks. Driver hang for single device on MP systems. Defect Description: PHKL_8906: The c720 driver does not lisc->sclk soon enough. Chip timing parameters are set up incorrectly. PHKL_8359: Select timeouts are retried forever. B_NDELAY should eliminate retries on select timeout. Zalon chip bug results in SCSI bus hang. PHKL_7637: NCR 53C710 and 53C700 chip bug. Missing SIOC_ABORT and SIOC_RESET_DEV functionality. Integer overflow in request timeout calculation. PHKL_7090: De422730, DSDe427313: Greely M/O's missing from non-wide multilun list. DSDe428060, DSDe428124: Dereference NULL pointer returned by scsi_mode_sense. DSDe427385: Dereference bogus DSP in c720_isrMA. DSDe427660: Dereference bogus pointer in isrDumpState script dump. DSDe427441, DSDe428177: Abort NOT averted by deferred command complete. DSDe427619: LSP_ABORT pushback in isrCA deactivates. DSDe428250: Request timeout integer overflow. Related: Bump sd_format_msecs to 24 hours. DSDe426840: km_io_alloc is too soon in open path. DSDe426722: close synchronization bug DSDe426499: QUANTUM/SCSI_DISK2 pass-thru veto even if open_cnt == 1. DSDe426662: Callout table overflow with scsi_retry entries. DSDe427253: Missing return after isrEscape in isrUntaggedReselect. DSDe425386: TEAC floppy driver does not correctly identify 5.25" 360K format. floppy: Add MODE SELECT in sf_set_geometry to work around firmware bug. DSDe428562: ioscan doesn't show correct s/w, h/w status for pass-thru driver. DSDe427008: Assertion failure due to c700_isr during if_reset_bus/c700_queuedone/scsi_cbfn. NODTSstall: Wasn't checking REQ in c700 for stalled phase mismatch. NODTSresid: Bogus scb->data_resid.

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_8906 5a. For a standalone system, run swinstall to install the patch: swinstall -x autoreboot=true -x match_target=true \ -s /tmp/PHKL_8906.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_8906.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_8906. 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_8906.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_8906.depot of=/dev/rmt/0m bs=2k Special Installation Instructions: None
