Creating Target Based Snapshots
ASM provides application consistent snapshots for Windows volumes (VSS). For
other operating systems you must use the command line utility to perform snapshot
operations. You can also snapshot logical devices using ASM, for non-Windows
operating systems. To perform a snapshot, launch ASM, right-click a logical device
and select the snapshot option. ASM will allow the user to create the snapshot
immediately or schedule the snapshot to occur at a later time.
To create a target based snapshot:
Note
Ensure to disconnect all the initiators before creating a target based snapshot.
1
Create a logical device using manual provisioning from ASM.
2
Set the authentication type to either CHAP or None and assign to any initiator.
3
Login to the new logical device and store data in it.
4
Log off the initiator.
Note
Always log off the parent before creating a target based snapshot, as target
based snapshots are not application consistent snapshots.
5
Select the target in the Enterprise View and right-click the logical device and
select Create Snapshot .
6
Provide a description to the target based snapshot.
7
Select the Access Type .
• Read Only
• Read Write
8
Select the Authentication Type .
• CHAP
• None
Note
By default the authentication type is set to be same as the parent.
9
Assign to the initiator.
Note
Assign to the provisioned system if you want to mount the TBS using mount
option.
10
When the target based snapshots are created the snapshots will be listed under
ASM snapshots in the Enterprise View.
Note
If you create CLI snapshots, they will be listed under third party snapshots.
