3. Confirm that the pair status of the P-VOLs of the GAD pairs has changed
to PSUS(Local) and that the pair status of the S-VOLs has changed to
SSUS(Block).
pairdisplay -g oraHA -fcxe -IH0
4. On the primary and secondary storage systems, disconnect the quorum
disks.
raidcom disconnect external_grp -ldev_id 0x9999 -IH0
Note: When you disconnect a quorum disk, SIM (DEF0ZZ*) (quorum disk
blockade) might be issued. If this SIM is issued, delete the SIM after
powering on the storage system and reconnecting the quorum disk.
*ZZ: quorum disk ID
5. On the primary and secondary storage systems, verify that the quorum
disks have been disconnected.
raidcom get path -path_grp 1 -IH0
6. Power off the primary and secondary storage systems and the external
storage system.
Powering on the primary, secondary, and external storage systems
1. Power on the primary and secondary storage systems and the external
storage system.
2. 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.
3. Check for SIMs about path blockage, and delete the SIMs.
4. On the primary and secondary storage systems, establish connections to
the quorum disks.
raidcom check_ext_storage external_grp -ldev_id 0x9999 -IH0
5. 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
6. Confirm that the external volumes of the primary and secondary storage
systems are recognized as quorum disks.
raidcom get ldev -ldev_id 0x9999 -IH0
7. Check for SIMs about quorum disk blockade, and delete the SIMs.
8. 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
9. Wait for more than 5 minutes after completing step 4, and then
resynchronize the GAD pairs from the primary storage system by
specifying the primary volume.
pairresync -g oraHA -IH0
10. 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
