Use the following procedure to power on the primary storage system.
- Power on the primary storage system.
-
Confirm that the storage systems do not have any blocked parts.
If any parts are blocked, recover them.
- Check for SIMs about path blockage, and complete the SIMs.
-
On the GAD secondary storage system, resynchronize the GAD pair by specifying the S-VOL (swap resync).
Command example: pairresync -g oraHA -swaps -IH1
A volume on the primary storage system changes to an S-VOL, and a volume on the secondary storage system changes to a P-VOL.
-
Confirm that the pair statuses are changed as shown in the following table.

Keep updating I/O to the P-VOL or GAD S-VOL for two minutes.
The information on the system configuration is reported among the primary, GAD secondary, and UR secondary storage systems. At the time, the UR delta resync pair status is changed from PSUE to PSUS. The mirror status of the journal is displayed as PJNS. Confirm that no failure SIMs are displayed.
