ECO NUMBER: VAXBACK03_062 ----------- PRODUCT: OpenVMS VAX Operating System 6.2 -------- UPDATED PRODUCT: OpenVMS VAX Operating System 6.2 ---------------- APPRX BLCK SIZE: 414 ---------------- COVER LETTER 1 KIT NAME: VAXBACK03_062 2 KITS SUPERSEDED BY THIS KIT: VAXBACK02_062 3 KIT DEPENDENCIES: 3.1 The following remedial kit(s) must be installed BEFORE installation of this, or any required kit: VAXY2K02_062. 3.2 In order to receive all the corrections listed in this kit, the following remedial kits should also be installed: VAXSYSA02_062 VAXMTAA03_062 VAXDISM02_062 VAXINIT01_062 VAXMOUN03_062 4 KIT DESCRIPTION: 4.1 Version(s) of OpenVMS to which this kit may be applied: OpenVMS VAX V6.2 4.2 Files patched or replaced: o [SYSEXE]BACKUP.EXE (new image) o BACKUP.CLD (file to update DCLTABLES.EXE) 5 PROBLEMS ADDRESSED IN VAXBACK03_062 o A possible system crash occurs during Host Based RAID Unbinds with MME code enabled. A mailbox read synchronization problem causes the crash. -- COVER LETTER -- Page 2 20 November 1998 This problem only occurs when a host-based RAID UNBIND command is done while an MME-based application is running. The problem may occur in several different code areas of the operating system. In order get eliminate all known instances of this problem, the following remedial kits (or their supersedants) will also need to be installed: VAXSYSA02_062 VAXMTAA03_062 VAXDISM02_062 VAXINIT01_062 VAXMOUN03_062 o A process using MME could potentially "miss" the VOL1 label on a tape. Also, a process could "hang" trying to send a message to the MME process. 6 PROBLEMS ADDRESSED IN VAXBACK02_062 KIT o The VAXBACK01_062 remedial kit should have included the BACKUP.CLD file to update DCLTABLES.EXE. After installing the VAXBACK01_062 kit, users saw error messages due to a missing /NO_INCREMENTAL qualifier. If systems in the cluster utilize different DCLTABLES, even if booting from a common system disk, this kit must be installed on those systems to update the DCLTABLES.EXE. 7 PROBLEMS ADDRESSED IN VAXBACK01_062 KIT o Incremental restores may get an INCDELERR error message and loop continuously when attempting to perform a directory tree delete on a specific DIR filespec. The following text is an example of the message syntax: %BACKUP-E-INCDELERR, error deleting $4$DUA153:[GHONEY.WINDATA.NETSCAPE.CACHE]CACHE.DIR;1 -SYSTEM-W-NOSUCHFILE, no such file o A possible ACCVIO (access violation) can occur when backing up volume sets, particularly individual relative volumes. o A possible loss of device cacheability when volume labels are overwritten could occur. Tape subsystems behave differently. Re-initializing a tape device cache value on volume switches may result in the loss of characteristic. The type of tape subsystem and it's stickiness of characteristic aggravates the -- COVER LETTER -- Page 3 20 November 1998 problem. o One cannot append to a non-expired tape on saveset appends when using the /EXACT_LABEL qualifier. Tape_expiration logic has a check specifically for the (/EXACT_LABEL) qualifier. o BACKUP may invoke a Restart operation during a network RESTORE operation when the link breaks. BACKUP was treating the network saveset read as if it were a tape device. o A new qualifier was added to invoke pre-OpenVMS V6.2 /SINCE behavior. After enhancements to INCREMENTAL restores was done, feedback from customers and Customer Support Centers (CSCs) indicated that not everyone was completely pleased with the new /SINCE behavior. o After installing VAXMOUN02_062, BACKUP/NOASSIST no longer works. However, BACKUP/ASSIST works fine. 8 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_3 : To be installed by customers experiencing the problems corrected. 9 INSTALLATION INSTRUCTIONS: Install this kit with the VMSINSTAL utility by logging into the SYSTEM account, and typing the following at the DCL prompt: @SYS$UPDATE:VMSINSTAL VAXBACK03_062 [location of the saveset] The saveset location may be a tape drive, or a disk directory that contains the kit saveset. No reboot is necessary after successful installation of the kit. Copyright (c) Compaq Computer Corporation, 1998 All Rights Reserved.
