Updating Host Information after Modifying the MV Pool
Validating Media 9-3
Validation Types
Stopping a Validation
If a host requests a cartridge currently being validated, the validation stops. You can
also stop the validation using SLC.
1.
Log in as the user who initiated the validation.
2.
In SLC, select Tools > Media Validation .
3.
Select the Media Validation tab.
4.
Click Stop .
Once validation stops, the cartridge is returned to its source location. If the source
location is lost, the library moves the cartridge to a system slot for host recovery.
Updating Host Information after Modifying the MV Pool
■
For ACSLS, you must initiate re-configuration after modifying the MV pool. Use
the
config drives <panel_id>
utility. For more information, see the ACSLS
Administrator's Guide .
■
For ELS, no action is required after modifying the MV pool. ELS hosts
automatically reconfigure.
Effect on HLI Hosts of Modifying the MV Pool
After adding drives to the MV pool, the library (or affected partition) will go offline.
The affected hosts receive "Configuration Changed", "LSM Ready", and then "Not
Ready" messages from the library. ELS automatically removes drives moved to the MV
pool from its configuration. ACSLS automatically updates drives moved to the MV
pool to an offline state, but ACSLS requires you to initiate re-configuration.
After removing drives from the MV pool, the library and partitions remain online. For
a non-partitioned library, the drive slots are available to hosts immediately. ELS hosts
begin re-configuration, but ACSLS hosts require you to initiate re-configuration. For a
partitioned library, you must allocate the drive slot removed from the MV pool to a
