How vmphyinv updates the EMM database

After all of the media are mounted and the tape headers are read, vmphyinv displays a list of recommended changes. Accept or reject the changes. If you accept the changes, vmphyinv updates the EMM database.

Table: vmphyinv criteria and actions

Criteria or action

Description

The vmphyinv update criteria

For valid media types, vmphyinv performs the following actions:

  • Changes the residence fields and description fields of any NetBackup media record if those fields do not match the media header.

  • Conditionally changes the media type of an unassigned NetBackup volume record. The media type is changed only if the new media type belongs to the same family of media types as the old media type. For example, the media type DLT can only be changed to DLT2 or DLT3.

  • Never changes the volume pool, media type, and ADAMM_GUID of an assigned record.

  • Never unassigns an assigned NetBackup volume.

How vmphyinv updates NetBackup media

The vmphyinv utility searches the EMM database. It checks if the media ID from the tape is present in the media ID field of any record in the EMM database. If the media ID exists, vmphyinv updates the NetBackup volume record that corresponds to the media ID. If the media ID does not exist, vmphyinv creates a new NetBackup volume record that corresponds to the NetBackup media.

vmphyinv error cases

The vmphyinv utility may not be able to update the EMM database correctly in the following cases. These cases are reported as errors.

If any of the following cases are encountered, you must intervene to continue:

  • Duplicate media IDs are found.

    Two or more media in the same robot have the same media ID.

  • A NetBackup volume record that belongs to a different robot is found.

    It contains the same media ID as the media ID read from the tape header.

  • The media type, media GUID, or volume pool of an assigned volume record needs to be changed.

  • The barcode of an existing volume record needs to be changed.
