Figure 1 Storing snapshot data for a group
Use the following process to store snapshot data:
1. Issue a request to store snapshot data for a group. To do this, run the raidcom modify
snapshot -snapshot_data create RAID Manager command.
2. The host issues a write request to each P-VOL in the group.
Snapshot data for the volumes are stored.
3. Store snapshot data for a consistency group or a snapshot group using the RAID Manager
command.
NOTE: You can use RWC only to reference consistency groups and snapshot groups.
