3.8.1 Units of SDX Object Operations

There are two types of backup operations (with different copy units for each type):

1. Backup operation in units of logical volumes (method with GDS Snapshot)

2. Backup operation in units of slices (method without GDS Snapshot)

For details on how to confirm and select the type of operation, refer to "3.8.1.1 Configuring Unit of SDX Object Operations"

Note

The two types of operation cannot be performed on the same Managed Server.

3.8.1.1 Configuring Unit of SDX Object Operations

The unit of SDX object operations is normally set as follows:

Units of Logical Volumes

When PRIMECLUSTER GDS Snapshot has been included PRIMECLUSTER GDS

Units of Slices

In cases other than the above

For operation in units of slices in an environment with PRIMECLUSTER GDS installed, use the command described in the stgxfwcmsetsdx command, and then set operation in units of slices by taking action as described in "3.4.4 Fetching Device Information on Managed Server".
