Solution

Problem

I/O to the volumes on the
failover system did not stop
before the synchronization.

1.

Stop I/O.

2.

Manually synchronize the remote-copy pair. On the failover system (SystemB),
enter either of the following commands:

syncrcopy

where represents the reversed volume group (multi.1.r96)

or:

syncrcopy -pat

where -pat represents the pattern of reversed volume group
names (multi*)

4.

To verify that the volume groups are started, issue the following command on the recovered
system (SystemA):

# showrcopy groups

where represents the volume group that should be started (multi.1).

Solution

Problem

The volume groups are not
started.

1.

On the recovered system, issue either of the following commands:

startrcopygroup

or:

startrcopygroup -pat

where -pat represents the pattern of volume group names (for
example, multi*).

2.

Wait for the synchronizations to complete before continuing.
