How vmphyinv processes cleaning media

If the following conditions are all true, vmphyinv does not try to mount the media and the next media in the list is mounted:

  • You do not specify the vmphyinv slot range or list option.

  • The robot contains cleaning media.

  • The media type is specified as cleaning media in the volume record (such as 4mm_clean or dlt_clean).

If the robot contains cleaning media and any of the following conditions are true, vmphyinv tries to determine if the media is cleaning media:

  • You use the slot range or list option and the media type of volume record in the EMM database is not a cleaning media type.

  • You use the slot range or list option, and the EMM database does not contain a volume record that corresponds to the cleaning media.

  • You do not use the slot range or list option, and the EMM database does not contain a volume record that corresponds to the cleaning media.

The vmphyinv utility tries to determine if the media is cleaning media. It uses the SCSI parameters (sense keys, tape alert flags, and physical (SCSI) media types) returned by the robot. If vmphyinv cannot determine if the media is cleaning media, it tries to mount the media until the mount request times out.

Note:

NetBackup may not detect the presence of cleaning media for all drives. Some drives report the presence of cleaning media in a manner NetBackup cannot read.
