First of all, it is important to understand that the name of a slot of a Catalyst device in Data Protector is equal to the name of the corresponding item on the store. Typically it looks like this: 3ef5dcb2_5645d8f4_11d4_0001. Please note the difference with the “Medium ID” which is looking similar but which is using colons rather than underscores, e.g. 3ef5dcb2:5645d8f5:11d4:0002. Also note the numbers for the slot ID and the Medium ID are looking similar, but are typically slightly different.
Now, when a medium is missing in the IDB, but the related item is still available on the store, it is possible to import the medium (either through the GUI or CLI). However, a slot is needed first. In some situations, the (empty) slot may still be there. The first slot in this picture is an example:
This slot could be imported through GUI or CLI.
If the slot is, for whatever reason, not available then it needs to be created before the import can be executed. Use the following command for the slot creation:
omnimm -add_slots <DP device name> <SlotID>
“DP device name” is the StoreOnce device in DP or the library name. “SlotID” is the item name on the store. The following command can be used to list the items on the store:
omnib2dinfo -list_objects -b2ddevice <DP device name>
