HP strongly recommends that a reboot is performed immediately after kit installation to avoid system instability. If you have other nodes in your OpenVMS cluster, they must also be rebooted in order to make use of the new image(s). If it is not possible or convenient to reboot the entire cluster at this time, a rolling re-boot may be performed. 2.3 Version(s) of OpenVMS to which this kit may be applied: OpenVMS ALPHA V7.3-2 2.4 New functionality or new hardware support provided: No 3 KITS SUPERSEDED BY THIS KIT: - VMS732_XFC-V300 4 KIT DEPENDENCIES: 4.1 The following remedial kit(s), or later, must be installed BEFORE installation of this, or any required kit: - VMS732_PCSI-V0300 - VMS732_UPDATE-V1000 Page 2 4.2 In order to receive all the corrections listed in this kit, the following remedial kits, or later, should also be installed: - None 5 NEW FUNCTIONALITY AND/OR PROBLEMS ADDRESSED IN THE VMS732_XFC-V0400 KIT 5.1 New functionality addressed in this kit Not Applicable 5.2 Problems addressed in this kit 5.2.1 Limit the Maximum Number of Closed Files Retained in Cache 5.2.1.1 Problem Description: Excessive use of non-paged pool by XFC closed files could lead to non-paged pool allocation failures and bugchecks. The maximum number of closed files that XFC will retain in the cache is now limited so that XFC will use no more than one half of the original size of non-paged pool (the SYSGEN parameter NPAGEDYN). This value will be approximately 1500 files per megabyte of non-paged pool. For example, if the SYSGEN parameter NPAGEDYN is 30,000,000 then then XFC will retain no more than about 45,000 closed files in the cache. Images Affected: - [SYS$LDR]SYS$XFCACHE.EXE - [SYS$LDR]SYS$XFCACHE.STB - [SYS$LDR]SYS$XFCACHE_MON.EXE - [SYS$LDR]SYS$XFCACHE_MON.STB - [SYSLIB]XFC$SDA.EXE 5.2.1.2 CLDs, and QARs reporting this problem: Page 3 5.2.1.2.1 CLD(s) QXCM1000381194 5.2.1.2.2 QAR(s) 75-109-1201,75-109-1838 5.2.1.3 Problem Analysis: XFC did not limit the number of closed files retained in the cache. Normally this was not an issue, but on some large systems, the number of closed files can exceed 500,000. Since XFC uses a small amount of non-paged pool for each file, in the extreme case, this large number of files could result in non-paged pool allocation failures and bugchecks. 5.2.1.4 Release Version of OpenVMS that will contain this change: Next release of OpenVMS Alpha after V8.3 5.2.1.5 Work-arounds: None. 5.2.2 REFCNTNEG Bugcheck 5.2.2.1 Problem Description: The system can crash with an "REFCNTNEG, PFN reference count is negative" bugcheck. Images Affected: - [SYS$LDR]SYS$XFCACHE.EXE - [SYS$LDR]SYS$XFCACHE.STB - [SYS$LDR]SYS$XFCACHE_MON.EXE - [SYS$LDR]SYS$XFCACHE_MON.STB - [SYSLIB]XFC$SDA.EXE Page 4 5.2.2.2 CLDs, and QARs reporting this problem: 5.2.2.2.1 CLD(s) QXM1000381970 5.2.2.2.2 QAR(s) None. 5.2.2.3 Problem Analysis: XFC was leaving the IRP in a state where I/O post processing was miscalculating the length of the PTE list after an error for a large page I/O (larger than 256 blocks). 5.2.2.4 Release Version of OpenVMS that will contain this change: Next release of OpenVMS Alpha after V8.3 5.2.2.5 Work-arounds: None. 5.2.3 INVPTEFMT Bugcheck 5.2.3.1 Problem Description: The system can crash with an INVPTEFMT bugcheck. Images Affected: - [SYS$LDR]SYS$XFCACHE.EXE - [SYS$LDR]SYS$XFCACHE.STB - [SYS$LDR]SYS$XFCACHE_MON.EXE - [SYS$LDR]SYS$XFCACHE_MON.STB - [SYSLIB]XFC$SDA.EXE Page 5 5.2.3.2 CLDs, and QARs reporting this problem: 5.2.3.2.1 CLD(s) None. 5.2.3.2.2 QAR(s) None. 5.2.3.3 Problem Analysis: The IRP field irp$l_diabuf was not being restored properly when converting a readthrough or writethrough I/O to a readaround or writearound I/O. This only occurred with very large I/Os (larger than about 550 disk blocks). 5.2.3.4 Release Version of OpenVMS that will contain this change: Next release of OpenVMS Alpha after V8.3 5.2.3.5 Work-arounds: None. 6 PROBLEMS ADDRESSED IN PREVIOUS KITS Problems addressed by previously released VMS732_XFC ECO kits can be found in the following files: o VMS732_XFC-V100.RELEASE_NOTES o VMS732_XFC-V200.RELEASE_NOTES o VMS732_XFC-V300.RELEASE_NOTES Before kit installation, these files can be extracted from the kit via the following commands: o To extract all release notes files at once use: PRODUCT EXTRACT RELEASE_NOTES VMS732_XFC/VERSION= - /DESTINATION= destination_directory o To extract a single release notes file use: PRODUCT EXTRACT FILE VMS732_XFC/VERSION= V4.0 - /SELECT=[SYSUPD]release_note_name/DESTINATION=destination_directory Page 6 7 FILES PATCHED OR REPLACED: o [SYS$LDR]SYS$XFCACHE.EXE (new image) Image Identification Information image name: "SYS$XFCACHE" image file identification: "V1.0" image file build identification: "XBH4-0060111013" link date/time: 8-MAR-2007 11:28:48.02 linker identification: "A11-50" Overall Image Checksum: 1346727581 o [SYS$LDR]SYS$XFCACHE_MON.EXE (new image) Image Identification Information image name: "SYS$XFCACHE_MON" image file identification: "V1.0" image file build identification: "XBH4-0060111013" link date/time: 8-MAR-2007 11:28:49.23 linker identification: "A11-50" Overall Image Checksum: 3711538288 o [SYSLIB]XFC$SDA.EXE (new image) Image Identification Information image name: "XFC$SDA" image file identification: "V1.0" image file build identification: "XBH4-0060111013" link date/time: 8-MAR-2007 11:28:50.34 linker identification: "A11-50" Overall Image Checksum: 696137662 o [SYS$LDR]SYS$XFCACHE.STB (new file) o [SYS$LDR]SYS$XFCACHE_MON.STB (new file) 8 INSTALLATION INSTRUCTIONS 8.1 Test/Debug Image Loss In the course of debugging problems reported to OpenVMS Engineering, customers may be given debug or point-fix images to install. Typically, these images do not have the same image generation flags contained in images released via the OpenVMS remedial patch process. Because of this, any debug or point-fix image that is in the SYS$COMMON area, will be replaced by any image of the same name installed by this kit. If this occurs, you will lose any functionality that is provided by the replaced image. If you wish to retain these debug or point-fix images, you can take the following steps: Page 7 o Prior to installing this kit, move the test/debug image(s) to be saved to the SYS$SPECIFIC area. o During kit installation, you will be asked if you wish to delete the image(s) in SYS$SPECIFIC. You should answer NO for each image that you want to keep. o After installation completes, but before rebooting the system (if required), move the image(s) from SYS$SPECIFIC back to SYS$COMMON. 8.2 Compressed File This kit is provided as a Self Extracting ZIPEXE kit. To expand this file to the installable .PCSI file, run the file with the following command: $ RUN VMS732_XFC-V0400.ZIPEXE 8.3 Installation Command 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 VMS732_XFC[/SOURCE=location of Kit] Note that this kit will install with the /SAVE_RECOVERY_DATA option turned on. Using this qualifier will allow easy removal of the kit from the system in the event of problems. If you wish to disable this option you must use the /NOSAVE_RECOVERY_DATA qualifier on the PRODUCT INSTALL command. The /SAVE_RECOVERY_DATA qualifier is optional but highly recommended. Using this qualifier will allow easy removal of the kit from the system in the event of problems. The kit location may be a tape drive, CD, or a disk directory that contains the kit. The /SOURCE qualifier is not needed if the PRODUCT INSTALL command is executed from the same directory as the kit location. Additional help on installing PCSI kits can be found by typing HELP PRODUCT INSTALL at the system prompt. 8.4 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 logical name definitions and commands: Page 8 o To avoid the BACKUP question, define the following: $ DEFINE/SYS NO_ASK$BACKUP TRUE o To avoid the REBOOT question, define the following: $ DEFINE/SYS NO_ASK$REBOOT TRUE o To save replaced files as *.*_OLD define the following logical name as YES. If you do not wish to save replaced files, define the logical name as NO. Note that if you use the /SAVE_RECOVERY_DATA qualifier (recommended) on the PRODUCT INSTALL command all replaced files will be saved as part of that operation. There is no need to also save files as *.*_OLD: $ DEFINE/JOB ARCHIVE_OLD NO o Add the following qualifiers to the PRODUCT INSTALL command and add that command to the DCL procedure. /PROD=DEC/BASE=AXPVMS/VER=V4.0 [/SOURCE=location of Kit] o De-assign the logical names assigned For example, a sample command file to install the VMS732_XFC-V0400 kit would be: $ DEFINE/SYS NO_ASK$BACKUP TRUE $ DEFINE/SYS NO_ASK$REBOOT TRUE $ DEFINE/JOB ARCHIVE_OLD NO $! $ PROD INSTALL VMS732_XFC/PRODUCER=DEC/BASE=AXPVMS/VER=V4.0" $! $ DEASSIGN/SYS NO_ASK$BACKUP $ DEASSIGN/SYS NO_ASK$REBOOT $! $ exit $! 9 COPYRIGHT AND DISCLAIMER: (C) Copyright 2007 Hewlett-Packard Development Company, L.P.
