* To restore a path, delete and then add the path again. It may be necessary to delete and then add the secondary
system again.
To delete the secondary system or path, see “Deleting the Cnt Ac-J Z relationship ” (page 101) or “Deleting remote
paths ” (page 100) . To re-register, see “Configuring primary and secondary systems for Cnt Ac-J Z ” (page 62) . If you
cannot restore the path after performing these operations, contact HP for assistance.
Troubleshooting by suspension type
Troubleshooting information for suspended pairs by suspension type is provided in the following
