ECO NUMBER: VAXMSCP03_062 PRODUCT: OpenVMS VAX OPERATING SYSTEM 6.2 UPDATE PRODUCT: OpenVMS VAX OPERATING SYSTEM 6.2 COVER LETTER 1 KIT NAME: VAXMSCP03_062 2 KITS SUPERSEDED BY THIS KIT: VAXMSCP02_062 3 KIT DEPENDENCIES: 3.1 The following remedial kit(s) must be installed BEFORE installation of this kit: VAXCLUSIO01_062 3.2 In order to receive the all the corrections listed in this kit, the following remedial kits should also be installed: None 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]TMSCP.EXE (new image) o [SYSEXE]MSCP.EXE (new image) 5 PROBLEMS ADDRESSED IN VAXMSCP03_062 KIT o The VAXMSCP02_062 remedial kit required that the VAXCLUSIO01_062 kit be installed. If the user tried to install the VAXMSCP02_062 kit on a system that had both the VAXCLUSIO01_062 and OpenVMS VAX Y2K remedial kits installed, the VAXMSCP02_062 kit did not recognize that the VAXCLUSIO01_062 kit had been installed. This caused the VAXMSCP02_062 installation to fail. -- COVER LETTER -- Page 2 10 February 1998 There are no new ECO problem corrections in this kit. If you have installed the VAXMSCP02_062 remedial kit, you do not need to install the VAXMSCP03_062 remedial kit. 6 PROBLEMS ADDRESSED IN VAXMSCP02_062 KIT o If a customer upgraded their system to V6.2 from V6.1, the KITINSTAL.COM procedure, in kits that require the VAXCLUSIO01 remedial kit to be installed first, did not properly verify that the VAXCLUSIO01_062 remedial kit had been installed. 7 PROBLEMS ADDRESSED IN VAXMSCP01_062 KIT o TMSCP does not restore R2 properly before using the register as an MSCP message. This misuse has manifested either in a corrupted TMSCP$ERR_TBL which is the cause of the devices not being accessible or the system crashes are possible depending on the value in R2. This misuse IS manifested AS either a corrupted TMSCP$ERR_TBL, which is the cause of the devices not being accessible, or as a system crash, depending on the value in R2. o Mount issues a packack for the device. The client then issues a subsequent ONLINE command. During TMSCP/ONLINE processing, if the server finds an HQB address in the UQB$L_ONLINE_HQB field, it returns SUCCESS status with an ALONL subcode even though the HQB is not for the requesting host. When the client processes the successful ONLINE end message it issues a GUS. The server returns a unit-available for this command which causes the client TUDRIVER to reissue an ONLINE which starts the process all over again. It stays in this loop forever. o System crash (INVEXCEPTN) when TMSCP does not get a message buffer during configuration time when a connection to MSCP$TAPE is broken. o An inconsistent transfer count occurs when encountering a forced error on a drive. A drive directly attached (or HSx served) reports a different transfer count from the same drive served via the MSCP server. Code that attempts to determine the LBN of a forced error block by looking at the byte count in the IOST/IOSB will arrive at different values on the same drive when directly accessed or MSCP served. -- COVER LETTER -- Page 3 10 February 1998 8 PROBLEMS ADDRESSED IN VAXMSCP01_070 KIT o The problem occurs when ERASE commands with history logging are issued on MSCP clients for large numbers of blocks to MSCP devices served by an OpenVMS MSCP server. On an Alpha server, an "Illegal Command" entry will be posted in the system error log and the command will be aborted. Typically, if the affected device is part of a shadow set, the set will enter mount verification and the I/O request will eventually fail with a "Fatal Controller Error". On a VAX server, no immediate problem is noticed but the possibility of corrupting a shadow set exists should there be a failure during the execution of the ERASE command and a mini-merge is performed when the set becomes available. o A satellite node will not boot after a preferpath/forcepath command is issued on the server. o Word instructions are used to reference a byte field. 9 KIT INSTALLATION RATING: The following kit installation rating, based upon current CLD information, is provided to serve as a guide as to which customers should apply this remedial kit. (Reference attached Disclaimer of Warranty and Limitation of Liability Statement) INSTALLATION RATING: INSTALL_2 : To be installed by all customers using the following feature(s): Customers who are MSCP serving disks and tapes need to install this kit. 10 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 VAXMSCP03_062 [location of the saveset] The saveset location may be a tape drive, or a disk directory that contains the kit saveset. The images in this kit will not take effect until the system is rebooted. If you have other nodes in your VMS 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 -- COVER LETTER -- Page 4 10 February 1998 rolling re-boot may be performed.
