*OpenVMS, ABS] ABSE02022 Archive/Backup System for OpenVMS ECO Summary
TITLE: *OpenVMS, ABS] ABSE02022 Archive/Backup System for OpenVMS ECO Summary
ON HOLD: Engineering is currently researching a problem with this
ECO and has requested that it be placed on Engineering Hold.
Modification Date: 08-JAN-99
Modification Type: Updated Kit: Put on HOLD
NOTE: An OpenVMS saveset or PCSI installation file is stored
on the Internet in a self-expanding compressed file.
The name of the compressed file will be kit_name-dcx_vaxexe
for OpenVMS VAX or kit_name-dcx_axpexe for OpenVMS Alpha.
Once the file is copied to your system, it can be expanded
by typing RUN compressed_file. The resultant file will
be the OpenVMS saveset or PCSI installation file which
can be used to install the ECO.

ECO KIT SUMMARY:
An ECO kit exists for Archive/Backup System V2.2 on OpenVMS VAX V6.1
through V7.1 and OpenVMS Alpha V6.1 through V7.1-1H2. This kit
addresses the following problems:
Problems Addressed in ABSE02022:
o If an NT or UNIX save request using a stacker device required a
volume continuation, the save request would fail and the following
error was displayed:
%SLS-E-PARTOFSET
o If ABS restored a file from a save set that spanned multiple volumes
of a volume set, and the last volume in the volume set was involved,
ABS left the volume set locked. If an ABS save or restore attempted
to use that volume set, ABS would wait for the volume to become
unlocked. A message similar to following would be repeated in the
save or restore request log file:
COORDINATOR: Attempting to allocate volume set ABS102...
o When performing a UNIX or an NT incremental save operation using
ABS, if the path name specified in the save request was the same as
the path name specified on a save request for a different UNIX or NT
system, the backup dates selected for the incremental save operation
may not have been correct. Because ABS did not include the node name
of the UNIX or NT system, ABS selected the most recent backup dates
for the incremental save operation, regardless of which system the
file was backed up from.
o During a multi-volume restore operation, ABS would not deallocate
the drives completely. ABS would allocate additional drives to
continue the restore operation. If there were not enough drives
available, the restore operation would wait for a drive and never
complete.
o If a save request for a UNIX or NT system continued onto a new
volume, ABS would not update the volume set record to reflect the
correct length of the volume set. This would cause the next save
request to load the previous volume rather than the correct volume
with the end-of-volume indicator.
o ABS save or restore requests with the file type of VMS Files may fail
while attempting to load the continuation volume of a multi-volume
set. This applies only to magazine loaders (Tx8nn DLT, TLZnL and 4mm
DAT loaders) that automatically eject the current volume and load
the next following a DISMOUNT/UNLOAD function. The problem involves
a hardware feature of magazines loaders where cartridges
automatically eject and load (from the next sequential slot)
following a software DISMOUNT/UNLOAD command. ABS must then eject
the auto-loaded volume and replace it with a volume from the
magazine meeting volume selection criteria. The problem symptoms
occur when ABS fails to wait for completion of the auto-eject-load
before sending commands to load the selected volume.
Symptoms of the problem vary depending on system configuration:
o The device type and controller interface (HSJ controllers
produce different symptoms than directly-connected SCSI
controllers). Device timing of the auto-eject-load also effects
symptoms.
o The sequence of volume selection from the magazine (selection
in the reverse direction may succeed whereas selection in the
forward direction may fail).
Depending on the system configuration, one or more of the following
symptoms may occur:
o Error message %SLS-F-MRD_SLOT_FULL appearing in the log file of
the Save/Restore.
o Error message %SLS-F-MRD_UNLOAD_FAIL.
o One or more entries in the system hardware error log file.
o Device/controller timeout resulting in HSJ controllers setting
the tape device misconfigured and unavailable as
shown by the HSJ command SHOW Unit.
o ABS save and restore requests fail when the output drive is located
in a DCSC-controlled jukebox. The log file of the save or restore
request shows the following failure status message, regardless of
whether there are free volumes in the database:
%SLS-E-NOVOLUME, %SLS-E-NOVOLUME, the volume does not exist in
the SLS database
o The ABS coordinator fails with ACCVIO termination after encountering
end-of-tape during a multi-volume save or restore operation. This
problem occurs on Alpha systems only. The PC of the ACCVIO varies
from system to system, but a consistent footprint is shown in the
following instruction stream at the PC of the ACCVIO (as shown by
ANALYZE/SYSTEM while an ABS process running the file COORDINATOR.EXE
is active):
SDA> SET PROCESS/INDEX= ! Process index
SDA> EXAMINE/INSTRUCTION @422E04-4;10 ! PC=422E04 as an example
00000000.00422DFC: RET R31,(R26)
00000000.00422E00: LDA SP,#xxxxx(SP)
00000000.00422E04: STQ R27,(SP) ! Loc of ACCVIO
00000000.00422E08: STQ R26,#xxxxx(SP)
o Minor Error Messages Removed
o In previous versions of ABS, the following message would be
recorded in the ABS$LOG:POLICY_ENGINE_T.LOG file:
-E- LOG FILE OPEN FAILED
o Minor error messages were displayed during the unpacking of
staging catalogs.
Problems Addressed in ABSE01022:
o The NT Client was not Y2K compliant. The Gtar image used for the
NT client has been fixed to support Y2K.
o ABS SHOW RESTORE was displaying destination twice. The extra display
of destination was removed from ABS SHOW RESTORE.
o ABS SHOW
