Patch Name: PHKL_8359 Patch Description: s700 10.10 SCSI subsystem cumulative patch Creation Date: 96/08/22 Post Date: 96/09/05 Warning: 96/11/14 - This Critical Warning has been issued by HP. When installed on 710, 715/50, 720 and 725/50 systems this patch may cause "SCSI Unhandled Interrupt" panics. Also "SCSI Unhandled Interrupt" messages may show up in dmesg(1M)'s output. Patch PHKL_7090 will be reposted till a replacement patch is available. It is suggested that the patch be deinstalled from all systems that suffer the particular panic. Since the panic happens before any filesystem, include root "/", is mounted filesystem integrity is not at risk. Hardware Platforms - OS Releases: s700: 10.10 Products: N/A Filesets: OS-Core.CORE-KRN Automatic Reboot?: Yes Status: General Superseded With Warnings Critical: Yes PHKL_8359: HANG PHKL_7090: PANIC HANG Path Name: /hp-ux_patches/s700/10.X/PHKL_8359 Symptoms: PHKL_8359: Select timeouts are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_8359: Select timeouts are retried forever. B_NDELAY should eliminate retries on select timeout. Zalon chip bug results in SCSI bus hang.

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_8359 5a. For a standalone system, run swinstall to install the patch: swinstall -x autoreboot=true -x match_target=true \ -s /tmp/PHKL_8359.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_8359.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_8359. 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_8359.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_8359.depot of=/dev/rmt/0m bs=2k Special Installation Instructions: None
