Hitachi G1000 - Planned Power Off;On of the Secondary and External Storage Systems; Powering off the Secondary and External Storage Systems

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 1-2 -IH1
6. Confirm that external volumes of the primary and secondary storage
systems are recognized as quorum disks.
raidcom get ldev -ldev_id 0x8888 -IH1
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(Block) and that the pair status of the S-VOLs is SSWS(Local).
pairdisplay -g oraHA -fcxe -IH1
9. Wait for more than 5 minutes after completing step 4, and then
resynchronize GAD pairs from the secondary storage system by reversing
the primary and secondary volumes (swap resync).
pairresync -g oraHA -swaps -IH1
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 -fcx -IH1
11. Using the alternate path software, resume I/O from the servers to the
storage system at the primary site.
12. If necessary, reverse the primary and secondary volumes.
Planned power off/on of the secondary and external storage
systems
Powering off the secondary and external storage systems
1. Direct server I/O to the storage system at the primary site.
Using the alternate path software, stop I/O from the servers to the
secondary storage system.
2. On the primary storage system, suspend the GAD pairs by specifying the
primary volume.
pairsplit -g oraHA -r -IH0
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.
