Volume Group Advanced properties
There is a single page layout for advanced properties of all Volume Groups.
Advanced properties
Pre Load: Pre-Load enabling. Enabling Pre-Load can be useful for the NonStop
restore/recover of multi-volumes tape files, when a restore script must be
executed before the volume can be read by the NonStop.
When Pre-Load is enabled, the load of the next volume is anticipated (and the
restore script initiated) while the previous volume is being read by the NonStop
tape application.
Refer to the Pre-Load section in the product description.
The Pre-Load processing requires two virtual tape drives per NonStop restore
process.
Auto Unload Timeout: Minimum time (in seconds) that a volume will be kept
loaded but unused. A tape loaded by process that is no longer running is
unloaded when resources are searched for a new mount request.
Authorized Access Information
This section defines the default authorizations that are assigned to the volumes each
time they are loaded for output. Refer to “Control of Access to Virtual Volumes” in the
first chapter.
Each element of the section defines a group of user-ids, relatively to the owner of the
volume:
N Any node, any user-id
C Any node, same group number
U Any node, same user-id
