pprc灾难切换命令

本实验验示了做了存储系统容灾后,发生灾难时切换操作.

Summary of the failover procedure
Briefly, this is the procedure we followed to switch to the recovery site:
1. Stop applications at the production site.
2. Verify the Metro Mirror volume pairs.
3. freezepprc and unfreezepprc (optional).
4. failoverpprc B to A (to DS8000#2).
5. mkpprcpath B to A (to DS8000#2).
6. Start applications at the recovery site.

Summary of the failback procedure
Briefly, this is the procedure we followed to switch to the production site:
1. Verify paths status B to A.
2. Eventually mkpprcpath B to A.
3. failbackpprc B to A (to DS8000#2).
4. Wait for volume pairs synchronization.
5. Quiesce applications at the recovery site (B).
6. failoverpprc A to B (to DS8000#1).
7. mkpprcpath A to B.
8. failbackpprc A to B (to DS8000#1).
9. Wait for volume pairs synchronization.
10.Start applications at the production site (A).
11.Eventually rmpprcpath B to A.
