Direct server I/O to the secondary storage system.
Using the multi-path software, stop I/O from the servers to the primary storage system.
- On the secondary storage system, suspend the GAD pairs (swap suspension) by changing the pair status of the S-VOLs to SSWS.
pairsplit -g oraHA -RS -IH1
-
Confirm that the pair status of the P-VOLs of the GAD pairs has changed to PSUS(Block) and that the pair status of the S-VOLs has changed to SSWS(Local).
pairdisplay -g oraHA -fcxe -IH1
-
On the primary and secondary storage systems, disconnect the quorum disks.
raidcom disconnect external_grp -ldev_id 0x8888 -IH1
Note: When you disconnect a quorum disk, SIM (def0zz) (quorum disk blockade) might be issued (zz: quorum disk ID). If this SIM is issued, complete the SIM after powering on the storage system and reconnecting the quorum disk. -
On the primary and secondary storage systems, verify that the quorum disks have been disconnected.
raidcom get path -path_grp 1 -IH1
- Power off the storage system at the primary site and the external storage system.
