Patch Name: PHNE_10814 Patch Description: s700_800 10.01-[12]0 2.2X ACC X.25 Protocol FW (EISA) Patch Creation Date: 97/04/28 Post Date: 97/06/06 Hardware Platforms - OS Releases: s700: 10.01 10.10 10.20 s800: 10.01 10.10 10.20 Products: Z7401A 2.21 2.22 2.23; Z7434AA 2.21 2.22 2.23; Filesets: ACC-X25.ACC-X25-FW Automatic Reboot?: No Status: General Superseded Critical: Yes PHNE_10814: PANIC PHNE_9285: PANIC Path Name: /hp-ux_patches/s700_800/10.X/PHNE_10814 Symptoms: PHNE_10814: SR 4701349928 / DTS TPO0h01198: System panic or DMA timeout occurs occasionally during ACC start up while downloading EISA ACC card. PHNE_9288: No ACC X.25 Protocol FW (EISA) related symptoms for this patch. PHNE_9285: SR 4701344473 / DTS TPO0h00994: DMA timeouts and system panics can occur when the EISA ACC is used and the onboard LAN interface is busy on some D-class and C-class systems. PHNE_9284: No ACC X.25 Protocol FW (EISA) related symptoms for this patch. 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: No ACC X.25 Protocol FW (EISA) related symptoms for this patch. PHNE_8833: No ACC X.25 Protocol FW (EISA) related symptoms for this patch. Defect Description: PHNE_10814: SR 4701349928 / DTS TPO0h01198: The EISA ACC firmware was not checking for an empty fifo condition while using programmed I/O to read an immediate mode command from the hp-ux host. PHNE_9288: No ACC X.25 Protocol FW (EISA) related defects were fixed in this patch. PHNE_9285: SR 4701344473 / DTS TPO0h00994: The ACC firmware was not correctly setting up the logic which controls the data transfers from the EISA bus into the ACC card memory for host to card transfers. The logic would fail to stop writing to the ACC card memory when the data transfer over the EISA bus was paused. When the onboard LAN was busy, the transfers to the EISA ACC card could be slowed causing the problem to appear. PHNE_9284: No ACC X.25 Protocol FW (EISA) related defects were fixed in this patch. 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: No ACC X.25 Protocol FW (EISA) related defects were fixed in this patch. PHNE_8833: No ACC X.25 Protocol FW (EISA) related defects were fixed in this patch.

Supersedes: PHNE_8833 PHNE_8991 PHNE_9283 PHNE_9284 PHNE_9285 PHNE_9288 Equivalent Patches: None Patch Package Size: 130 Kbytes Installation Instructions: Please review all instructions and the Hewlett-Packard SupportLine User Guide or your Hewlett-Packard support terms and conditions for precautions, scope of license, restrictions, and, limitation of liability and warranties, before installing this patch. ------------------------------------------------------------ 1. 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_10814 5a. For a standalone system, run swinstall to install the patch: swinstall -x autoreboot=true -x match_target=true \ -s /tmp/PHNE_10814.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_10814.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_10814. 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_10814.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_10814.depot of=/dev/rmt/0m bs=2k Special Installation Instructions: After installing this patch relink any custom firmware download files (.zabs) that have been created. The ACC subsystem must then be stopped and restarted using zmasterd in order to download the new firmware.
