manually start the remote copy group between A—B before you proceed with any other SRM
operations.
• During the reprotect operation, SRA triggers delta resync operation from C—A and C—B,
where C is the new primary system after failover. If the SRM recovery operation was performed
when either A—B or B—C or both the remote copy links are down, then as per the remote
copy behavior, reprotect operation triggered by SRM through SRA will initiate a full copy from
C—B only (from C—A delta resync will be initiated).
• SRM recovery operation initiated at C will do a delta sync from B to C and then initiate the
failover operation at C. When the A—C link is down, under certain conditions, as per the
remote copy behavior, the data transfer from B—C will go into full-sync mode during SRM
recovery operation at C.
Workaround: When all the remote copy links are UP, run the SRM Test operation at least once
before executing the disaster recovery at ‘C’ when the A—C link is down to avoid “B—C”
going to FULL SYNC.
