Lost Media report
The Lost Media report lists expired media that has not been returned from the off-site vault vendor.
Media that appear on the Lost Media report have the following:
An assigned date of 0 or are frozen.
A robot number value of null.
A vault sent date value that is non-null.
A non-null return date.
Media can get lost for various reasons, as follows:
A volume appears on the Picking List for Vault only once. If a volume from that report is missed and is not returned to the robot, it never again is listed for recall.
Frozen backup media never expires. Media that does not expire does not appear on the Picking List for Vault and is not recalled from the vault.
You change or rename your off-site volume groups and pools. For example, if you begin using a new media type, you have to use a new volume pool name. Cohesity recommends that you do not change or rename group or pool names.
You must generate the Lost Media report; it is not generated when you eject media. You do not have to configure your profiles for the Lost Media report. Usually, the media that are included in the Lost Media report should be returned from off-site and injected back into the appropriate vault in the robot.
A good practice is to run the Lost Media report periodically, such as weekly or monthly (depending on your operations).
Column descriptions in the Lost Media report are as follows:
DENSITY | Density of the volume. |
LAST MOUNT | The date the volume was last mounted. |
MEDIA ID | The ID of the media. |
REQUESTED | Date when the volume is requested back from the off-site vault. |
