Compaq StorageWorks Data Replication Manager HSG80 ACS Version 8.5P Operations Guide

Configuring a Data Replication Manager Solution 4–11
22. For OpenVMS: Set the SCSI version, alloclass, and identifier with the following
commands:
SET THIS SCSI_VERSION = SCSI-3
SET ALLOCLASS = 1
SET THIS IDENTIFIER = 99
Setting this switch causes the host to load the SYS$GDRIVER, which provides the
GG devices. The value range is 1 - 99.
23. For OpenVMS and Windows NT: Check to see if mirrored write-back cache is
enabled by using the following CLI command:
SHOW THIS_CONTROLLER
You will see a display similar to the following:
Mirrored Cache:
Not enabled
.
.
.
If it is not enabled, issue the following CLI command:
SET THIS_CONTROLLER MIRRORED_CACHE
The controllers will restart after mirrored write-back cache has been set, and you will
see %LFL and %EVL displays.
NOTE: It may take up to five minutes after restart to check cache. The controllers will reject this
command until cache check is complete. If this command is rejected, don’t restart the
controllers. Wait a few minutes, then retry.
24. After the controllers restart, issue the following CLI command to confirm that
mirrored write-back cache is enabled:
SHOW THIS_CONTROLLER
Notice that mirrored write-back cache is now set:
.
.
.
Mirrored Cache:
256 megabyte write cache, version 0012
Cache is GOOD
No unflushed data in cache
.
.
.
It is not necessary to repeat this step on controller B.
