5–10 Compaq StorageWorks Data Replication Manager HSG80 ACS Version 8.5P Operations Guide
NOTE: Be sure that the units you see (listed under “Initiator State”) are at the target site and not
the initiator site units.
4. To verify that the target hosts can connect to the LUNs, use this command:
SHOW UNITS FULL
In the Access field of the display, all units should show that the target hosts are
enabled. This should also show the initiator controller connections.
5. For Windows NT, reboot the server at the target site, and log in as Administrator. You
should be able to see all of the drives in My Computer.
6. For OpenVMS, if the target site hosts are shut down, boot them at this time. Booting
the hosts enables OpenVMS to recognize the drives. If the target site hosts are not shut
down, use the following command from a privileged account to enable OpenVMS to
recognize the drives:
MCR SYSMAN I0 AUTOCONFIGURE/LOG
Simple Failback Procedure
This procedure is used with the Planned Failover Procedure.
Status Comparison
■ Before performing the failback procedure, locate your record of SHOW command
output that details the initiator configuration. Verify that your target controller
configuration is the same as your initiator controller configuration.
■ Compare the status of the controllers, association sets, remote copy sets, units, and
connections by following the procedure outlined below.
Simple Failback Initiator Preparation
1. Shut down the initiator hosts if they are still up and running. (This is not necessary for
OpenVMS.)
2. The controllers should have been powered down since the failover procedure. If this is
not the case and it is possible that writes have occurred to the units since the failover
procedure was executed, use the full failback procedure on page 5-19 of this chapter.
3. Power up the controller cabinet(s).
