must be a valid ID. The valid IDs can be found in the Affinity list for any cartridge in the robot. Use the
command “mtlib -l <device name> -qV -V<volume name>” to obtain the Affinity list for a cartridge.
Polling Interval (tape only). The number of seconds to wait between polling requests performed by the
PVL to determine if any media is present in the drive. Use -1 to disable polling. Values of 0 to 14 are not
valid.
Advice - The value for tape drives located within robotic libraries should be set higher than for
manually mounted drives. It is recommended that this field be set to 15 seconds for operator-mounted
tape drives and 900 (15 minutes) for library-managed tape drives.
Mounted Volume (disk only). The 8-character name of the volume mounted on the disk drive.
Drive Pool ID (tape only). If non-zero positive integer value, the Drive Pool ID will restrict this drive to
only be scheduled for tape read requests specifying this value. The default Drive Pool ID is 0 to indicate
that the drive is not restricted to a particular drive pool. Negative values are not allowed. See Section 7.3:
Drive Pools on page 218.
Comment. This field provides a 128 character buffer in the PVL drive metadata which gives the
administrator the opportunity to associate miscellaneous text with a device/drive. For example, a site may
want to place a comment in this field that the drive is out of service or being used by another system, etc.
