Restoring a Mirror (Resuming a Copy Operation)
A mirror is a combination of a master journal group and a restore journal group. If you split a
mirror, the copying of data from the master journal group to the restore journal group will be
suspended. To restart the copying of data, you need to restore the mirror. As for mirror in Hold
status, you need to restore the mirror in order to restart the copying of data.
To restore a mirror, follow the procedure below. Only the primary storage system administrator
can perform this operation; the secondary storage system administrator cannot perform this
operation:
