Patch Name: PHKL_15292 Patch Description: s700 10.20 VME Services Cumulative Patch Creation Date: 98/05/14 Post Date: 98/05/29 Hardware Platforms - OS Releases: s700: 10.20 Products: N/A Filesets: VME-Services.VME-BPN VME-Services.VME-KRN Automatic Reboot?: Yes Status: General Superseded Critical: Yes PHKL_15292: PANIC System will panic on 747/742 if "bpn" driver is configured and "vmebpn_sockets" is not set to 0. Path Name: /hp-ux_patches/s700/10.X/PHKL_15292 Symptoms: PHKL_15292: 1) If the system is not rebooted after installing PHKL_12876 the lanscan command does not output any information. 2) File mode access permissions for /usr/lib/lanscan/libpebp0.1 are set incorrectly. PHKL_12876: 1) System will panic on 747/742 if the VME BPN pipes driver is active ("VME Backplane AF_VME_LINK Domain Driver") This driver is configured into the system by SAM when the "bpn" driver is selected and the tunable "vmebpn_sockets" is set to the default state specified by the master file /usr/conf/master.d/vmebpn ( vmebpn_sockets = 1). 2) System will not support a 742/747 diskless boot over backplane networking("VME Backplane TCP/IP driver"). This driver is configured into the system by SAM when the "bpn" driver is selected and the tunable "vmebpn_tcp_ip" is set to the default state specified by the master file /usr/conf/master.d/vmebpn ( vmebpn_tcp_ip = 1 ). 3) System will encounter failures with VME DMA and mapping services on a 744. 4) The lanscan command will not work properly for VME_BPN PHKL_11224: 1) Use of system V shared memory shmat() or file based shared memory mmap() call will cause the vme2_ioctl() command VME2_USER_COPY to fail. 2) vme_dma_setup() may cause VME bus errors if invoked with the VME_USE_IOMAP option active. 3) VME2_USER_COPY transfers the SAME 256k bytes for data transfers larger than 256K. 4) VME_USER_COPY does not limit transfers to MAXPHYS length Defect Description: PHKL_15292: 1) Patch PHKL_12876 did not specify that a reboot is required after installation. 2) Access control for the libebp0 lanscan library was improperly set by PHKL_12876 postinstall script. PHKL_12876: 1) VME Backplane AF_VME_LINK Domain Driver requires hardware capabilities not supported on a 747/742 and should therefore be disabled in this platform. 2) The "VME Backplane TCP/IP driver" link layer access functionality required by the 742/747 boot protocol (rbootd) was prematurely omitted from this driver for 10.20. It is not supported at 10.30 and beyond. 3) VME services must update the kernel variable niopdir with information from the vme_io_estimate tunable ( plus an additional esimate factor ). On a 744 The VME_SV module is reported in a different location in the HP-UX io tree from a 743, causing this update code not to be run. The consequent shortage of available io pages may cause failures with the DMA and mapping functions. 4) VME BPN does not correctly update the hwift structure necessary for proper functioning of the lanscan command PHKL_11224: 1) VME Services makes invalid assumptions about kernel space id values with respect to shared memory, not exposed until shared memory used in a 10.X environment. 2) Detected at 9.05 ( but problem is present at 10.X). VME Services does not lock VME bus when accessing slave mapper configuration registers in vme_dma_setup(). Failure to do this may cause bus errors. 3) Kernel data pointer not properly updated 4) Incorrect checking for MAXPHYS.

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_15292 5a. For a standalone system, run swinstall to install the patch: swinstall -x autoreboot=true -x match_target=true \ -s /tmp/PHKL_15292.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_15292.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_15292. 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_15292.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_15292.depot of=/dev/rmt/0m bs=2k Special Installation Instructions: None
