Configuring Stacker Devices
What Are Stacker
Devices? A stacker is a single device with one drive and sequentially accessed
media. Using stacker devices requires more human media management
than using a small library. Data Protector provides simple configuration
and management of media used in stacker backup devices.
How to Configure
a Stacker Device? To create a stacker device, specify the Stacker device type in the Add
Device wizard. For detailed steps, refer to the online Help index keyword
“configuring stacker devices”.
Stacker Device
Media
Management The operations scan, verify, or format have to be run separately on each
medium in a stacker device. When performing these operations, use the
Eject medium after operation option, in order to have each medium
loaded automatically (only the first medium should be loaded manually).
When all the tapes in the stacker magazine are used, the magazine must
be unmounted manually and the next one inserted.
Stackers load media in sequential order, therefore a Loose media
allocation policy is recommended. A Strict policy would require media
to be loaded in the same order as they are to be used.
Example 1. Manually load the first medium.
2. Run format/verify/scan (with Eject after operation enabled) --
(next tape will be loaded automatically).
3. Repeat step 2 until all tapes are finished.
4. When all the tapes in the stacker magazine are used, unmount the
magazine manually and insert the next one.
NOTE If a medium is not properly loaded, Data Protector will abort the medium
session.
