OpenVMS ALPBACK02_062 Alpha V6.2 Backup Utility ECO Summary
TITLE: OpenVMS ALPBACK02_062 Alpha V6.2 Backup Utility ECO Summary
Modification Date: 29-NOV-1999
Modification Type: Updated Article to remove incorrect information
regarding ALPMOUN04_062.
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 BACKUP on OpenVMS Alpha V6.2 through V6.2-1H3
This kit addresses the following problems:
PROBLEMS ADDRESSED IN ALPBACK02_062 KIT:
o MailBox Read synchronization problem in MME_MBX_COMM
A possible system crash occurs during Host Based RAID Unbinds
with MME code enabled. A mailbox read synchronization problem
causes the crash.
This problem only occurs when a host-based RAID UNBIND command
is done while an MME-based application is running.
This problem may occur in several different code areas of the
operating system. In order to eliminate all instances of this
problem, the following remedial kits (or their supersedants)
will also need to be installed:
o ALPSYSA02_062
o ALPDISM02_062
o ALPINIT01_062
o ALPMOUN04_062
o ALPMTAA02_062
PROBLEMS ADDRESSED IN ALPBACK01_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
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 ALPMOUN02_062, BACKUP/NOASSIST no longer
works. However, BACKUP/ASSIST works fine.
INSTALLATION NOTES:
The system does not need to be rebooted after this kit is installed.
However, if you have other nodes in your OpenVMS VMScluster, they should
be rebooted or you should install this kit on each system in order to
make use of the new image(s).
