Computer Drive User Manual

This window allows the user to import tape volumes into the HPSS system, making them known to the
PVL server. To make them known to the Core Server so they can be used by HPSS, storage resources
must then be created for the volumes via the Create Tape Resources window.
When the Max Number of Drives is set to 1, the volumes are processed one at a time in sequence. If an
error occurs, processing stops. The window completion message will report the number of successful
imports, from which the volume causing the failure can be found. For example, if you requested import
of 100 volumes, and the completion message showed that 37 imports were successful, then the 38th
volume in the Volume List caused the failure.
When the Max Number of Drives is greater than 1, the SSM System Manager effectively starts multiple
import jobs (equal to Max Number of Drives) which run at the same time. Each job independently
processes part of the Volume List, and stops when its part of the list is done or when an error occurs. The
window completion message shows only the total of all successful imports from all of these jobs. It is
therefore impossible to tell from this number which volume caused the failure. In this case it is important
to review the Alarms and Events window to get more information on the failures.
If you request the import of a volume which was previously imported, the System Manager counts this as
