The following procedure is for recovering from a system down failure of the storage system at the target primary site.
-
If a temporary failure occurs at the target GAD primary site,
turn on the power of the storage system at the target GAD primary site
and then remove the cause of the failure.
The pair status for the P-VOL and S-VOL of the different pairs will be as follows:
- For the target GAD pair: PSUE(Local) for the P-VOL and COPY for the S-VOL
- For the target UR pair: PSUE for both P-VOL and S-VOL
- For the temporary GAD pair for migration: PSUE(Local) for the P-VOL and PSUE(Block) for the S-VOL
-
Delete the target UR pair.
Command example:
pairsplit -g UR10 -S -IH11
-
Delete the target UR delta resync pair.
Command example:
pairsplit -g UR11 -S -IH12
-
Forcibly delete the target GAD pair.
Command example:
pairsplit -g HA10 -RF -IH12 pairsplit -g HA10 -SFV -IH11
-
Resynchronize the temporary GAD pair used for migration.
Command example:
pairresync -g HA20 -IH01
