Patch Name: PHKL_8361 Patch Description: s700 10.01 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_6547 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Platforms - OS Releases: s700: 10.01 Products: N/A Filesets: OS-Core.CORE-KRN Automatic Reboot?: Yes Status: General Superseded With Warnings Critical: Yes PHKL_8361: HANG PHKL_6547: HANG PHKL_6027: PANIC HANG in general, this patch is not needed on s700 unless you experience the panic with scsi floppy installed or you are adapting s700's to high availability (HA) environments. note that this patch may slow down some operations on devices which are not ready to be accessed (e.g., devices with no media installed). Path Name: /hp-ux_patches/s700/10.X/PHKL_8361 Symptoms: PHKL_8361: Select timeouts are retried forever, i.e. I/O's never complete when a device is removed. SCSI bus hang and reset. PHKL_7827: Incorrect geometry determination for 5.25" 360K floppy. Too long request timeout, 2 min. 30 sec. on EISA SCSI. Missing SIOC_ABORT and SIOC_RESET_DEV functionality. PHKL_6547: auto retries of open on CD-ROM with no media can cause hang PHKL_6027: scsi problems, including 743 w/scsi floppy panic on boot and potential subsystem hangs Defect Description: PHKL_8361: Select timeouts are retried forever. B_NDELAY should eliminate retries on select timeout. Zalon chip bug results in SCSI bus hang. PHKL_7827: TEAC floppy firmware bug. NCR 53C710 and 53C700 chip bug. Missing SIOC_ABORT and SIOC_RESET_DEV functionality. PHKL_6547: a kmio struct was allocated even if the open failed. see the SR for the reproduction methods. PHKL_6027: 743 w/floppy panic on boot occurs if iodc search is performed prior to booting hp-ux -- this leaves scsi bus in hung state. potential subsystem hangs occur following request timeouts from drives that the driver does not recover from properly.

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_8361 5a. For a standalone system, run swinstall to install the patch: swinstall -x autoreboot=true -x match_target=true \ -s /tmp/PHKL_8361.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_8361.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_8361. 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_8361.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_8361.depot of=/dev/rmt/0m bs=2k Special Installation Instructions: None
