ECO NUMBER: VMS721_MOUNT96-V0300 PRODUCT: OpenVMS Alpha OPERATING SYSTEM V7.2-1 UPDATE PRODUCT: OpenVMS Alpha OPERATING SYSTEM V7.2-1 COVER LETTER 1 KIT NAME: VMS721_MOUNT96-V0300 2 KITS SUPERSEDED BY THIS KIT: None. 3 KIT DEPENDENCIES: 3.1 The following remedial kit(s), or later, must be installed BEFORE installation of this, or any required kit: - VMS721_PCSI-V0100 - VMS721_UPDATE-V0300 3.2 In order to receive all the corrections listed in this kit, the following remedial kits, or later, should also be installed: - VMS721_SYS-V1100 - VMS721_CLIUTL-V0200 - VMS721_FIBRE_SCSI-V0500 4 KIT DESCRIPTION: 4.1 Version(s) of OpenVMS to which this kit may be applied: OpenVMS Alpha V7.2-1 4.2 Files patched or replaced: o [SYSLIB]MOUNTSHR.EXE (new image) o [SYSEXE]SYSINIT.EXE (new image) o [SYSEXE]VMOUNT.EXE (new image) -- COVER LETTER -- Page 2 11 October 2001 5 PROBLEMS ADDRESSED IN VMS721_MOUNT96-V0300 KIT o Some reads to disk devices will occasionally fail as a result of a path failover. If this happens during a read of the home block, then MOUNT will read the alternate home block and continue to MOUNT the device. Depending on which read failed, the MOUNT may mount the disk writelocked or display other warning messages. Images Affected: - [SYSLIB]MOUNTSHR.EXE - [SYSEXE]VMOUNT.EXE o Roxio CD Creator V5.0 for PCs creates a disk that is not compliant to the ISO standard. Attempting to MOUNT these disks on an OpenVMS system will crash the system with an SSRVEXCEPT, Unexpected system service exception bugcheck. Crash Dump Summary ------------------ Bugcheck Type: SSRVEXCEPT, Unexpected system service exception Current Process: DKA400CACP Current Image: $82$DKA0:[SYS0.SYSCOMMON.] [SYSEXE]F11CACP.EXE Failing PC: FFFFFFFF.800ACD10 EXE$QIO_C+00170 Failing PS: 30000000.00000001 Module: IO_ROUTINES (Link Date/Time: 29-MAR-2000 00:52:23.33) Offset: 0001AD10 Images Affected: - [SYSLIB]MOUNTSHR.EXE - [SYSEXE]VMOUNT.EXE o On volumes where the INDEXF.SYS file size exceeds the MAXFILES value for the volume, a volume rebuild operation will ACCVIO. VERIFY shows no problems but the commands to rebuild the volume will consistently fail. Note: To receive this complete change you must also install the VMS721_CLIUTL-V0200 ECO kit. Images Affected: -- COVER LETTER -- Page 3 11 October 2001 - [SYSLIB]MOUNTSHR.EXE o A SET VOLUME/REBUILD command on a volume set, where a node that had it mounted did not update the volume write count on dismount (or a crash), does not reset the volume write count to the correct number of writers in the cluster. A SHOW DEVICE/REBUILD command always shows this volume as needing a rebuild. Even a SET VOLUME/REBUILD=FORCE will not clear this rebuild status. Note: To receive this complete change you must also install the VMS721_CLIUTL-V0200 ECO kit. Images Affected: - [SYSLIB]MOUNTSHR.EXE - [SYSEXE]SET.EXE o o A MOUNT/NOWRITE command on a disk on one cluster will now work correctly even if the disk is mounted with a /WRITE qualifier on another cluster in the SAN (Storage Area Network). Previously, depending on the order in which the mounts were executed, the mount would fail with the error message: DIFVOLMNT - different volume already mounted on this device. o If a disk is mounted with a /WRITE qualifier on one cluster and a /NOWRITE qualifier on another cluster in the SAN, MountVerification will fail with a WrongVolume status error on the system which had the disk mounted /NOWRITE. This change allows MountVerification to complete successfully in this configuration. Note: To receive this complete correction you must also install the VMS721_SYS-V1100 and VMS721_FIBRE_SCSI-V0500 ECO kits. Images Affected: - [SYSLIB]MOUNTSHR.EXE - [SYSEXE]VMOUNT.EXE -- COVER LETTER -- Page 4 11 October 2001 o Read failures during MOUNT that were due to an inability to read the home block and failures that were due to transient errors, such as from a path switch or SCSI bus reset, were following the same failure path. That is, reading the alternate home block and if successful mounting the disk as read only. Failures due to transient errors should not read the alternate home block and should mount the disk as READ/WRITE. For transient error failures, this change will now cause the READ to be re-tried for for 30 seconds (30 re-tries at one per second). If the READ succeeds, the disk will be mounted as READ/WRITE. Images Affected: - [SYSEXE]VMOUNT.EXE - [SYSLIB]MOUNTSHR.EXE 6 KIT INSTALLATION RATING: The following kit installation rating, based upon current CLD information, is provided to serve as a guide to which customers should apply this remedial kit. (Reference attached Disclaimer of Warranty and Limitation of Liability Statement) INSTALLATION RATING: INSTALL_1 : To be installed by all customers. 7 INSTALLATION INSTRUCTIONS: Install this kit with the POLYCENTER Software installation utility by logging into the SYSTEM account, and typing the following at the DCL prompt: PRODUCT INSTALL VMS721_MOUNT96 /SOURCE=[location of Kit] The kit location may be a tape drive, CD, or a disk directory that contains the kit. Additional help on installing PCSI kits can be found by typing HELP PRODUCT INSTALL at the system prompt No reboot is necessary after successful installation of this kit. If you have other nodes in your VMScluster, they should be rebooted or install this kit in each system in order to make use of the new image(s). -- COVER LETTER -- Page 5 11 October 2001 7.1 Special Installation Instructions: 7.1.1 Image Installation If you have other nodes in your VMScluster, an INSTALL/REPLACE command will need to be issued on each node in order to make use of the images in this kit. The commands needed are: INSTALL/RELACE [SYSLIB]MOUNTSHR.EXE/SHARE/OPEN/HEADER/PROT INSTALL REPLACE [SYSEXE]VMOUNT.EXE 7.1.2 Scripting of Answers to Installation Questions During installation, this kit will ask and require user response to several questions. If you wish to automate the installation of this kit and avoid having to provide responses to these questions, you must create a DCL command procedure that includes the following definitions and commands: 1. Define logical NO_ASK$REBOOT as TRUE 2. Add the following qualifiers to the PRODUCT INSTALL command and add that command to the DCL procedure. /PROD=DEC/BASE=AXPVMS/VER=V3.0 3. De-assign the logicals assigned For example, a sample command file to install the VMS721_MOUNT96-V0300 kit would be: $ DEFINE/SYS NO_ASK$BACKUP TRUE $! $ PROD INSTALL VMS721_MOUNT96/PROD=DEC/BASE=AXPVMS/VER=V3.0 $! $ DEASSIGN/SYS NO_ASK$BACKUP $ exit Copyright (c) Compaq Computer Corporation, 2001 All Rights Reserved.
