About the vmphyinv list of drives
The list of drives the vmphyinv utility uses to mount the media is obtained from the NetBackup database. The drives do not need to be configured locally.
You cannot specify which drives to use. However, you can specify the maximum number of drives to use, which lets you reserve drives for NetBackup backup or restore operations. Specify the number of drives by using the -drv_cnt drive_count option.
