ECO NUMBER: VAXMSCP01_071 ----------- PRODUCT: OpenVMS VAX Operating System -------- UPDATED PRODUCT: OpenVMS VAX Operating System 7.1 ---------------- APPRX BLCK SIZE: 1000 ---------------- COVER LETTER 1 KIT NAME: VAXMSCP01_071 2 KITS SUPERSEDED BY THIS KIT: None. 3 KIT DESCRIPTION: 3.1 Version(s) of OpenVMS to which this kit may be applied: OpenVMS VAX V7.1 3.2 In order to receive the full fixes listed in this kit the following remedial kits also need to be installed: None. 3.3 Files patched or replaced: o [SYSEXE]TMSCP.EXE (new image) o [SYSEXE]MSCP.EXE (new image) 4 PROBLEMS ADDRESSED IN VAXMSCP01_071 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$L_ONLINE_HQB field, it returns SUCCESS status with an ALONL subcode even though the HQB is not for the requesting host. -- COVER LETTER -- Page 2 9 June 1997 When the client processes the successful ONLINE end message it issues a GUS. The server returns a unit-available for this command which causes the client TUDRIVER to reissue an ONLINE which starts the process all over again. It stays in this loop forever. o System crash (INVEXCEPTN) when TMSCP does not get a message buffer during configuration time when a connection to MSCP$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. 5 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.
