Automigration/Replication Issues
Although Automigration is configured and managed through the Automigration/Replication tab
on Command View VLS, errors and events are reported through the usual notification alerts. See
Notification Alerts .
IMPORTANT: If a destination library is directly connected to the VLS (
LOOP
mode), and you
disconnect the destination library to change its connection to be via a SAN (
FABRIC
mode), you
will need to reboot the VLS in order for this change to work. If you do not reboot, the destination
library will be marked as
FAILED
after you disconnect and reconnect it.
NOTE: The “mirror_broken” state can occur when there is not enough room on the virtual tape
to create the copy, there are no available slots to create the copy, the library cannot read the
header of the physical tape, the library cannot determine that a tape without a header is blank,
or the library cannot successfully write the header to the virtual tape.
Destination library status icon
While the device status icon in the Command View VLS status banner indicates the overall VLS
device health on other tabs, the icon on the
Automigration/Replication tab indicates the status of
the destination libraries.
A destination library status icon can be one of five states:
Error —An error occurred while the system was determining the status of the destination libraries.
Unknown —A destination library's operating condition is unknown. Contact HP Technical Support.
Normal —All destination libraries are operating normally.
Warning —At least one destination library is in a good state while at least one destination library
is any state other than good.
Warning for All —All destination libraries are in any state other than good.
Replacing a library
When a library fails, or when the library robotics card must be changed, the replacement will
have a different serial number from the original. To assign it the same pools, mapping, etc. as the
original:
NOTE: While the virtual tapes are in the firesafe, scheduled backups for those tapes will not
occur.
1. Make a note of all pool configuration information for pools associated with the library to be
replaced.
2. Delete all pools associated with the library (see Deleting a Copy Pool ).
NOTE:
Deleting the pools automatically moves all virtual cartridges from within the pool to the firesafe.
3. Unmanage the physical library to be replaced (see Managing and Unmanaging a Destination
Library ).
4. Replace the library or robotics card.
5. Manage the new physical library (see Managing and Unmanaging a Destination Library ).
