Hitachi G1000 - Planned power off;on of the external storage system (I;O at primary site)

2. On the storage system at the primary site, suspend the GAD pairs by
specifying the primary volume.
pairsplit -g oraHA -r -IH0
3. Confirm that the pair status of P-VOLs of GAD pairs has changed to
PSUS(Local) and the pair status of the S-VOLs has changed to
SSUS(Block).
pairdisplay -g oraHA -fcxe -IH0
4. Power off the storage system at the secondary site.
Powering on the secondary storage system
1. Power on the storage system at the secondary site.
2. Confirm that the primary and secondary storage systems and the external
storage system for the quorum disk 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. 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
5. On the storage system at the primary site, resynchronize the GAD pairs
by specifying the primary volume.
pairresync -g oraHA -IH0
6. 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
7. Using the alternate path software, resume I/O from the servers to the
storage system at the secondary site.
Planned power off/on of the external storage system (I/O
at primary site)
Powering off the external storage system (I/O at primary site)
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
storage system at the secondary site.
2. On the storage system at the primary site, suspend the GAD pairs by
specifying the primary volume.
pairsplit -g oraHA -r -IH0
3. Confirm that the pair status of 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.
