Entering the cache

For the nbu_snap and VxFS_Snapshot methods, you must identify a raw partition that the copy-on-write process uses, in any of the following ways.

To enter the cache

If manually selecting the snapshot method on the Snapshot Client Options dialog, you have two options for specifying the raw cache partition:
- Under Host Properties > Clients > Client Properties dialog > UNIX Client > Client Settings, specify the raw partition in the Default cache device path for snapshots field. For example: /dev/rdsk/c1t0d0s6. This setting applies to the client in all policies.
- Or, under Policies > Attributes > Snapshot Client Options dialog, specify the raw partition in the Cache device path field. This cache setting applies to all clients in the current policy, and overrides the cache setting in the Client Settings dialog.
If you want NetBackup to select the nbu_snap or VxFS_Snapshot methods by means of the auto method, specify the cache on the Host Properties > Clients > Client Properties dialog > UNIX Client > Client Settings.
In a FlashBackup policy: if Perform snapshot backups is NOT selected, you must use a CACHE= directive in the Backup Selections tab.
This cache setting applies to all clients in the current policy and overrides the cache setting in the Host Properties dialog. (This means of configuring the cache will be discontinued in a future release.)
