Failback after SVOL-SMPL takeover
This failover situation occurs, for instance, when:
The original P-VOL status is unavailable
The S-VOL is changed to SMPL and unable to failback.
The Host B (DC1) sequence illustrated by the following figures is required
to change the SMPL volume to pvol_pair and make it suitable for failback.
From the Data Center 1 (DC1) side, the required steps are:
1. pairsplit –S
2. paircreate –vl
3. pairevtwait (wait for PAIR)
From the Data Center 2 (DC2) side, the required steps (not shown) would
be:
1. pairsplit –S
2. paircreate –vr
3. pairevtwait (wait for PAIR)
Refer to the state definitions in the table under the heading “HA control
script state transitions” on page 326.
Initial state:
