Snapshot Resources pane
The Snapshot Resources pane (on the policy's Snapshot Options dialog box) is available only for certain disk array snapshot methods on UNIX clients.
The Snapshot Resources pane provides the most control over Instant Recovery snapshots. You can specify which devices to use for the snapshots, and the order in which the devices are used. Click the option to display the following:
The serial number of the array is specified in the field. Contact your array administrator to obtain the disk array serial numbers and designators (unique IDs) for the array.
The unique ID snapshot resource or source LUN containing the primary data is specified in the .
The maximum number of snapshots to retain is determined by the number of configured devices in the field. For example, if you enter two devices, only two snapshots can be retained. The above example specifies three devices (0122;0123;0124), so three snapshots can be retained. When the maximum is reached, the fourth snapshot overwrites the first one.
The particular devices to use for the snapshots are those named in the field.
The order in which the devices are listed in the field determines their order of use. Device 0122 is used for the first snapshot, 0123 for the second, and 0124 for the third.
Preconfiguration of the snapshot devices may be required.
See the appropriate topic for your disk array and snapshot method.
