For a VSP or HUS using HDP/HDT that has replicated LDEVs (either local or remote), what is the correct procedure to expand the P-VOL and S-VOL using HCS and HRpM?
- Suspend the pair (PSUS state) in HRpM
- Delete the pair (SIMPLEX state) in HRpM. Horcm files remain intact.
- Expand DP Volume within DP Pools screen on HCS for P-VOL and S-VOL (obviously target capacities must be identical)
- Recreate the original pair relationship in HRpM
Or can you omit the pair deletion step and just resync from PSUS after expanding the DP volumes?
Thanks in advance!
