8 Release Notes – Data Replication Manager HSG80 ACS Version 8.6-4P
Rolling Upgrade
The rolling upgrade procedure is documented in the SANworks by Compaq Data
Replication Manager HSG80 ACS Version 8.6-4P Configuration Guide. The
procedure is designed to allow an array controller software upgrade without the need
for a server reboot. However, you must ensure that all the latest drivers, and if
applicable, the latest release of Secure Path are installed prior to this upgrade.
Installing the latest drivers may require the server to be rebooted. Information on the
latest supported drivers and Secure Path can be found in the Software Support
Matrix at:
http://www.compaq.com/products/sanworks/drm/softwaresupport.html.
Scripting
Scripting for automated failover and failback procedures are supported for Windows
2000/NT, Compaq OpenVMS, Compaq Tru64 UNIX, IBM AIX, and Sun Solaris
operating systems. For more information on automated procedures, refer to the
Compaq SANworks Data Replication Manager HSG80 ACS Version 8.6-1P Scripting
User’s Guide. For manual procedures, refer to the Compaq SANworks Data
Replication Manager HSG80 ACS Version 8.6-4P Failover/Failback Procedures
Guide.

Performance Considerations—Adding Target Unit Back to
Remote Copy Sets
When you add back the target unit to the remote copy sets with the following
command,
SET RemoteCopySetName ADD = TargetRemoteCopyName\UnitName
Example: set rcs1 add = buildngA\d1
it forces each remote copy set into a full normalization. In some cases this will have an
impact on data replication performance and, as such, should not be performed during
periods of high target site I/O activity. You may wish to stagger the startup of the
normalization of each remote copy set to minimize the performance impact.
