- Power on the primary and secondary storage systems and the external storage system.
-
Confirm that the primary and secondary storage systems and the external storage system for the quorum disks 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 primary and secondary storage systems, establish connections to the quorum disks.
raidcom check_ext_storage external_grp -ldev_id 0x9999 -IH0
-
On the primary and secondary storage systems, verify that the connections to the quorum disks have been established.
raidcom get external_grp -external_grp_id 1-1 -IH0
-
Confirm that the external volumes of the primary and secondary storage systems are recognized as quorum disks.
raidcom get ldev -ldev_id 0x9999 -IH0
- Check for SIMs about quorum disk blockade at the primary and secondary sites, and complete the SIMs.
-
Confirm that the pair status of the P-VOLs of the GAD pairs is PSUS(Local) and that the pair status of the S-VOLs is SSUS(Block).
pairdisplay -g oraHA -fcxe -IH0
-
Resynchronize the GAD pairs from the primary storage system by specifying the primary volume.
pairresync -g oraHA -IH0
-
Confirm that the pair status of the P-VOLs and S-VOLs of the GAD pairs has changed to PAIR (Mirror (RL)).
pairdisplay -g oraHA -fcxe -IH0
- Using the multi-path software, resume I/O from the servers to the storage systems at the primary and secondary sites.
