Patch Name: PHNE_17026 Patch Description: s700_800 10.20 2.40[.01] X.25/ACC Protocol Product Patch Creation Date: 98/11/29 Post Date: 98/11/30 Hardware Platforms - OS Releases: s700: 10.20 s800: 10.20 Products: Z7404AA APZ Filesets: ACC-X25.ACC-X25-FW ACC-X25.ACC-X25-KRN ACC-X25.ACC-X25-MAN Automatic Reboot?: Yes Status: General Superseded Critical: No Path Name: /hp-ux_patches/s700_800/10.X/PHNE_17026 Symptoms: PHNE_17026: SR 5003437947 For NIO 8-port ACC cards, DMA timeout was occurring during ZCOM/ACC subsystem startup in HP K class systems (and potentially any T series) with 2 or more ACC cards installed. The problem is faster to reproduce if 2 ACC cards have failing ports and/or the ACC cards are not numbered consecutively (0, 1, 2, etc.) in the user's ACC .answ file. PHNE_15354: DTS NONE Inbound Call indication packet is lost when the packet arrives *immediately* after a Restart exchange resulting in "Application timeout on inb. call" message in ZCOM log file. DTS TPO0h02042: 4-ch card: LAPB/LAPD loses timers in the timer download control request. DTS TPO0h01946: 4-ch card: LAPB/LAPD layer can get frames out of sequence after receiving a REJ. SR 5003398362 / DTS TPO0h01774: A large number of short packets received with the M-bit set can lead to a firmware failure (ACC card restart). SR None / DTS TPO0h01974: X25 firmware can corrupt queues on cable disconnect and reconnect. The X25 link can no longer manage calls correctly once this has happened. SR 4701391862 / DTS TPO0h01966: No current method to determine hardware revision TPO0h01893: Man page for x25stat has an incorrect library reference PHNE_14011: SR NONE / DTS TPO0h01833 8-channel NIO card crashes, with the use of the frame protocol and hdlcabm protocol together on the same port. SR NONE / DTS TPO0h01640 The following trace shows that the 2-ch ACC card transmits a bad frame (search for BAD) at the beginning of link setup. 10:03:45/310.3 1- TD D1 FRAME len=0034 flg=0002 01 44 10 01 13 00 f1 01 59 01 3f 01 3f 01 3f 01 BAD! 3f 01 3f 01 3f 01 3f 01 3f 01 3f 01 3f 01 3f 01 01 3f 10:03:45/546.9 1- RD D1 FRAME len=0002 flg=9999 01 0f SR NONE / DTS TPO0h01755 This problem was spotted in dump files In addition to the incorrect REJ, the retry mechanism for the unsatisfied REJ is incorrect. SR NONE / DTS TPO0h01641 Trace shows unrecogised frame is received the response is a FRMR, as it should be (see BAD). 18:29:26/739.4 1- RD D1 FRAME len=0002 flg=9999 D2 (01) DISC P/F=0 18:29:26/739.8 1- TD D1 FRAME len=0005 flg=9999 D2 (03) FRMR P/F=0 cmd=43 vr=007 vs=000 c/r=1 wxyz=0000 BAD! 18:29:27/378.0 1- RD D1 FRAME len=0002 flg=9999 D2 (01) DM P/F=0 Defect Description: PHNE_17026: SR 5003437947 The system part of the firmware was not verifying whether the LO-QUIX chip (responsible for managing backplane transactions) on the ACC card was ready before requesting another I/O operation. PHNE_15354: DTS NONE The X.25 driver uses a completion status message to signal when the Restart Exchange is complete. If an inbound call arrived before the completion status was passed by the firmware to the driver, the inbound call would be lost. This would appear as through the application was not acknowledging the inbound call. DTS TPO0h02042: 4-ch card: When timers are downloaded to the LAPB/LAPD protocol in the CW_TIMERS control write request, a system timer entry is wasted. Eventually the ACC card can run out of timers. DTS TPO0h01946: 4-ch card: When the HDLCABM or X25 protocol receives a REJ frame while it is in the process of retransmitting frames, it can get transmitted frames out of sequence. SR 5003398362 / DTS TPO0h01774: There was a bug in the X.25 firmware code, which caused queue corruption on the ACC whenever a short DATA packet was received (that's one which is less than the full packet size but with the M-bit set and without the D-bit set). The error handling causes the queue corruption. The ACC firmware can survive for some time with this queue corruption, but a lot of these errors will eventually cause the card to fail. SR None / DTS TPO0h01974: The level-2 LAPB layer could mistakenly leave frames on a transmit queue after the link has gone down. These frames then corrupt the processing after the link is re-established. A second bug causes the same symptom by allowing a level-3 flow-control packet to be transmitted after the SABM/UA exchange, with an incorrect sequence number. SR 4701391862 / DTS TPO0h01966 Enhancement to detect hardware revisions of ACC cards. A standard interface has been defined to identify hardware revisions of all ACC cards. The 'mx' command of zmntr has been enhanced to include the display of the hardware revision. TPO0h01893: Reference to library "libzx25.a" has been added to the x25stat man page. PHNE_14011: SR NONE / DTS TPO0h01833 Firmware failures with FRAME and HDLCABM concurrently in use SR NONE / DTS TPO0h01640 2ch card transmits bad frame on link startup SR NONE / DTS TPO0h01755 hdlcabm sends REJ on I-frame with duplicate N(s) SR NONE / DTS TPO0h01641 frame reject cause information is bad on unknown frame type SR: 4701380667 4701391862 5003398362 5003437947 Patch Files: /opt/acc/protocol/hdlcabm.zrel /opt/acc/share/man/man3.Z/x25stat.3x /opt/acc/protocol/zx25.zrel /opt/acc/z7350a/x25.zabs /opt/acc/z7350a/x25.zmap /opt/acc/z7200a/x25.zabs /opt/acc/z7200a/x25.zmap /opt/acc/z7400a/x25.zabs /opt/acc/z7400a/x25.zmap /opt/acc/z7330a/x25.zabs /opt/acc/z7300a/x25.zabs /usr/conf/lib/libzx25d.a what(1) Output: /opt/acc/protocol/hdlcabm.zrel: ZCOM HDLC ABM Protocol ACC Rel B.02.40/B.02.40.01 for B.10.20 PHNE_17026 a bm.cp ZCOM HDLC ABM State Tables Rev:1.12 981123.1126 ACC Rel B.02.40/B.02.40.01 for B.10.20 PHNE_17026 a bmfsm /opt/acc/share/man/man3.Z/x25stat.3x: None /opt/acc/protocol/zx25.zrel: ZCOM X.25 Protocol ACC Rel B.02.40/B.02.40.01 for B.10.20 PHNE_17026 z x25.z ZCOM X.25 Level 2 ACC Rel B.02.40/B.02.40.01 for B.10.20 PHNE_17026 a bm.cp ZCOM HDLC ABM State Tables Rev:1.12 981123.1126 ACC Rel B.02.40/B.02.40.01 for B.10.20 PHNE_17026 a bmfsm /opt/acc/z7350a/x25.zabs: ZCOM System Firmware (ROM) Rev 01.T5 ACC Rel B.02.40/B.02.40.01 for B.10.20 PHNE_17026 z 7350_ ZCOM Z7350A System Software ACC Rel B.02.40/B.02.40.01 for B.10.20 PHNE_17026 z 7350_ CPU clock 32MHz ZCOM LEVEL1 Protocol ACC Rel B.02.40/B.02.40.01 for B.10.20 PHNE_17026 l evel1 ZCOM X.25 Protocol ACC Rel B.02.40/B.02.40.01 for B.10.20 PHNE_17026 z x25.z ZCOM X.25 Level 2 ACC Rel B.02.40/B.02.40.01 for B.10.20 PHNE_17026 a bm.cp ZCOM HDLC ABM State Tables Rev:1.12 981123.1126 ACC Rel B.02.40/B.02.40.01 for B.10.20 PHNE_17026 a bmfsm ZCOM HDLC ABM Protocol ACC Rel B.02.40/B.02.40.01 for B.10.20 PHNE_17026 a bm.cp ZCOM HDLC ABM State Tables Rev:1.12 981123.1126 ACC Rel B.02.40/B.02.40.01 for B.10.20 PHNE_17026 a bmfsm ZCOM Monitor Module ACC Rel B.02.40/B.02.40.01 for B.10.20 PHNE_17026 m onito ZCOM Port Diagnostic Module ACC Rel B.02.40/B.02.40.01 for B.10.20 PHNE_17026 t estpr ZCOM Protocol Module Entry Point Table ACC Rel B.02.40/B.02.40.01 for B.10.20 PHNE_17026 p mentt /opt/acc/z7350a/x25.zmap: ZCOM System Firmware (ROM) Rev 01.T5 ACC Rel B.02.40/B.02.40.01 for B.10.20 PHNE_17026 z 7350_ ZCOM Z7350A System Software ACC Rel B.02.40/B.02.40.01 for B.10.20 PHNE_17026 z 7350_ CPU clock 32MHz ZCOM LEVEL1 Protocol ACC Rel B.02.40/B.02.40.01 for B.10.20 PHNE_17026 l evel1 ZCOM X.25 Protocol ACC Rel B.02.40/B.02.40.01 for B.10.20 PHNE_17026 z x25.z ZCOM X.25 Level 2 ACC Rel B.02.40/B.02.40.01 for B.10.20 PHNE_17026 a bm.cp ZCOM HDLC ABM State Tables Rev:1.12 981123.1126 ACC Rel B.02.40/B.02.40.01 for B.10.20 PHNE_17026 a bmfsm ZCOM HDLC ABM Protocol ACC Rel B.02.40/B.02.40.01 for B.10.20 PHNE_17026 a bm.cp ZCOM HDLC ABM State Tables Rev:1.12 981123.1126 ACC Rel B.02.40/B.02.40.01 for B.10.20 PHNE_17026 a bmfsm ZCOM Monitor Module ACC Rel B.02.40/B.02.40.01 for B.10.20 PHNE_17026 m onito ZCOM Port Diagnostic Module ACC Rel B.02.40/B.02.40.01 for B.10.20 PHNE_17026 t estpr ZCOM Protocol Module Entry Point Table ACC Rel B.02.40/B.02.40.01 for B.10.20 PHNE_17026 p mentt /opt/acc/z7200a/x25.zabs: ZCOM System Firmware (ROM) Rev 04.B 921106.1200 ACC Rel B.02.40/B.02.40.01 for B.10.20 PHNE_17026 z 7200_ ZCOM System Software (WMUX1) ACC Rel B.02.40/B.02.40.01 for B.10.20 PHNE_17026 w mux1.

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_17026 5a. For a standalone system, run swinstall to install the patch: swinstall -x autoreboot=true -x match_target=true \ -s /tmp/PHNE_17026.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_17026.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_17026. 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_17026.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_17026.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.
