Installing Your Backup Software
After you set the required CP 3100 configuration values, install your backup software if it is not
already installed (refer to the manual that came with the software for information about installing
and using it). The backup software recognizes your CP 3100 as a DAT 72 or DDS-4 autoloader with
25 slots (tapes).
Verifying Your Installation
After you configure the CP 3100 and install your backup software, use the backup software to per-
form a small backup operation. Refer to the manual that came with the software for information
about performing backup operations.
CP 3100 Operation
The CP 3100 operates as follows:
•
The CP 3100 supports DDS 4 and DAT 72 tape drives.
•
If a DDS 4 is attached, the CP 3100 emulates a DDS 4 autoloader.
•
If a DAT 72 is attached, the CP 3100 emulates a DAT 72 autoloader.
In both cases, the autoloader has 25 slots by default to let you set up tape rotation schemes
with your backup and restore software.
•
If the backup and restore software unloads a virtual tape cartridge at the end of a backup, the
backed up data will be scheduled for archive to tape 5 minutes after the backup completes.
When an archive is started, the CP 3100 raises an Attention for you to insert a physical tape
cartridge, if necessary.
•
Data is automatically migrated (removed from the disk cache) when additional space for new
backups is required. Data will only be migrated if it has been successfully archived (written to
tape) previously. Data is migrated using a least recently used (LRU) algorithm, which migrates
data starting with the oldest backed-up data.
