Patch Name: PHNE_9283 Patch Description: s700_800 10.10 2.22 Z7401A ACC X.25 Bundled Product Patch Creation Date: 96/11/24 Post Date: 96/11/29 Hardware Platforms - OS Releases: s700: 10.10 s800: 10.10 Products: HP Z7401A Filesets: ACC.ACC-KRN ACC-X25.ACC-X25-FW ACC-X25ST.ACC-X25ST-KRN Automatic Reboot?: Yes Status: General Superseded Critical: No Path Name: /hp-ux_patches/s700_800/10.X/PHNE_9283 Symptoms: PHNE_9283: SR 4701341719 / DTS TPO0h00745 / DTS TPO0h00804: A system panic can occur when receiving messages greater than 28672 bytes. The long messages can be generated using the X.25 protocol and setting the M-bit (more data) on multiple packets. This problem affects systems with cache coherent I/O such as the C, D, and J-class. The panic is a "Data page fault". The message "DMA buffer mapping failure -1." is written to the system console when this problem occurs. Here is the stack trace for the panic. stack trace for event 0 crash event was a panic panic+0x10 report_trap_or_int_and_panic+0x8c interrupt+0x4e0 $ihndlr_rtn+0x0 eisa_unmap+0x4c nacc0_end_io+0x5c0 eacc0_isr+0x328 eisa_int+0x10c lasi_interrupt+0x18c mp_ext_interrupt+0x280 $RDB_int_patch+0x58 idle+0x344 PHNE_8991: SR 5000716860 / DTS TPO0h00741: A select() call which waits for the file descriptor associated with a program ZLU to become readable is not awakened when a message arrives on the ZLU input queue. The select call returns after the timeout has expired with the read fd mask indicating the ZLU fd is readable. Defect Description: PHNE_9283: SR 4701341719 / DTS TPO0h00745 / DTS TPO0h00804: Within the driver for the EISA ACC, the call to wsio_map() to map the zcom buffer for the inbound data fails and the error is not handled properly. When the DMA operation completes the panic occurs in the wsio_unmap() call. PHNE_8991: SR 5000716860 / DTS TPO0h00741: The driver zcom0 was calling selwakeup() with the wrong argument type. For hp-ux 10.10 the type was changed from (struct proc *) to (struct kthread *), but zcom0 was not updated. SR None: Some errors in setting the spl level for inbound events were corrected in the axin driver.

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 PHNE_9283 5a. For a standalone system, run swinstall to install the patch: swinstall -x autoreboot=true -x match_target=true \ -s /tmp/PHNE_9283.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/PHNE_9283.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/PHNE_9283. 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 PHNE_9283.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/PHNE_9283.depot of=/dev/rmt/0m bs=2k Special Installation Instructions: SUBSYSTEM_SHUT Before installing this patch, use the following command to shutdown the ACC subsystem and kill the ACC daemons. /opt/acc/bin/zmasterd kill The above command kills any of the ACC daemons that are still running, including zmasterd, zx25d, watch, zmlog, zmon, and znode. The kernel will be regenerated and the system will reboot automatically during the patch installation.
