Device pools

The HCL OneDB™ Primary Storage Manager pool is a named group of disk devices that you use as a repository for backups.

When storing backup objects, the OneDB Primary Storage Manager selects particular devices from the pool and moves automatically from one device to another when devices are full or when they fail. You maintain pools by using the onpsm utility to add, modify, view, and drop devices in the pool.

Three pools are available:

DBSPOOL

Holds online backups of dbspaces, blobspaces, and sbspaces

LOGPOOL

Holds online backups of logical logs

EXTPOOL

Serves as a staging area for exporting a backup set of objects to a single large, external logical object or for importing the backed up objects. You can move specific backups or backups generations in this pool to permanent storage or onto a different computer. Files in the EXTERNAL pool are offline. The files are not visible to ON-Bar, and the OneDB Primary Storage Manager does not track them.
