Resolving failures in multiple locations
If failures occur in multiple locations, use the following recovery procedure:
1. Identify the failure locations from the SIMs issued by the primary and
secondary storage systems and using the SAN management software,
and then recover from the failures.
2. If data has been lost from both volumes, recover from the backup data
using ShadowImage or Thin Image volumes, or backup software.
3. If I/O is stopped, resume I/O from the server.
4. If GAD pairs are suspended, resynchronize the pairs.
If the pairs cannot be resynchronized, delete the pairs and then create
them again.
