You can release the assignment of S-VOLs
from snapshot data of
Thin Image Advanced pairs.
Note: If the
amount of snapshot data in selected P-VOLs or the total number of pairs in selected
snapshot groups exceeds 32,768, an error message appears when attempting to perform
pair tasks.
The pages allocated to the S-VOL of the pair are
not released even if you perform this task. Therefore, when you view the capacity of
the pages allocated to the S-VOL after performing this task, you might find that the
value is not zero. To release the pages allocated to the S-VOL, format the S-VOL
after performing this task. Also, if you plan to use the volume as a volume other
than the Thin Image Advanced S-VOL, format the S-VOL after performing this
task
- You must have the Storage Administrator (Local Copy) role.
- Thin Image Advanced pairs must be in the PAIR status, PSUS status, or PSUE
status.
Releasing the assignment of S-VOLs
using CCI
commands
The following is an example of releasing the assignment of snapshot data from the
S-VOL (LDEV number 20:00):
raidcom unmap snapshot -ldev_id 0x2000
The following is an example of releasing the assignment of snapshot data from the
S-VOL (LDEV number 10:10) in the snapshot group (db1):
raidcom unmap snapshot -ldev_id 0x1010 -snapshotgroup db1
The following is an example of releasing the assignment of snapshot data from an
S-VOL by specifying the P-VOL (LDEV number 10:10, MU number 10):
raidcom unmap snapshot -ldev_id 0x1010 -mirror_id 10
Releasing the assignment of S-VOLs
using HDvM - SN
- In the Explorer pane, click Storage Systems, expand the storage system tree, expand Replication, and then click Local Replication.
- In the Local Replication window, select a P-VOL in the TI Root Volumes tab or a snapshot group in the Snapshot Groups tab.
- Click Operate TI Pairs.
- In the TI Pairs window, select the S-VOL pairs you want to delete, and then click .
You can specify P-VOLs in Device Manager - Storage Navigator until the total number of snapshots reaches 32,768. In
addition, you can specify snapshot groups until the total number of pairs
reaches 32,768.
