OpenVMS VMS712_SHADOWING-V0100 Alpha V7.1-2 Shadowing ECO Summary
TITLE: OpenVMS VMS712_SHADOWING-V0100 Alpha V7.1-2 Shadowing ECO Summary
Modification Date: 27-JAN-2000
Modification Type: New Kit
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 Shadowing on OpenVMS Alpha V7.1-2. This kit
addresses the following problems:
o When a copy operation that interrupts a merge operation is
terminating, it finds that there are no members marked for the
merge and the thread crashes the system with a SHADDETINCON
bug check.
Images Affected:
- [SYS$LDR]SYS$SHDRIVER.EXE
- [SYSEXE]SHADOW_SERVER.EXE
o SHOW DEVICES shows zero percent merged status although the
shadow set status does not indicate that a merge is required.
Images Affected:
- [SYS$LDR]SYS$SHDRIVER.EXE
- [SYSEXE]SHADOW_SERVER.EXE
o Bit 16 in SHADOW_SYS_DISK can be set by the user to eliminate
using remote members of the shadowset for reads. Occasionally,
use of bit 16 fails to eliminate remote members from being used.
Images Affected:
- [SYS$LDR]SYS$SHDRIVER.EXE
- [SYSEXE]SHADOW_SERVER.EXE
o A CPUSPINWAIT bug check can occur if the read of the SCB of
a shadow set member cannot pass the checksum test.
Images Affected:
- [SYS$LDR]SYS$SHDRIVER.EXE
- [SYSEXE]SHADOW_SERVER.EXE
o DCD (Disk Copy Data) will not always be initiated properly.
During an assisted copy operation, if the source member was
dismounted or otherwise removed from the shadow set, the
connection to the controller would not clean up correctly.
Images Affected:
- [SYS$LDR]SYS$SHDRIVER.EXE
- [SYSEXE]SHADOW_SERVER.EXE
o A full copy operation that is interrupted for a mini-merge
will not complete the full copy operation correctly.
Images Affected:
- [SYS$LDR]SYS$SHDRIVER.EXE
- [SYSEXE]SHADOW_SERVER.EXE
o Typing incorrect commands results in a system crash.
Images Affected:
- [SYS$LDR]SYS$SHDRIVER.EXE
- [SYSEXE]SHADOW_SERVER.EXE
o When two disks are added to a shadowset in the same mount
command, the copies are done sequentially instead of in
parallel. This causes the copies to take twice as long as
they should.
Images Affected:
- [SYS$LDR]SYS$SHDRIVER.EXE
- [SYSEXE]SHADOW_SERVER.EXE
INSTALLATION NOTES:
The images in this kit will not take effect until the system is
rebooted. If there are other nodes in the VMScluster, 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 rolling re-boot may be performed.
