A point-in-time restore of a library manager server can
create inconsistencies between the volume inventories of the library
manager and library client servers. Steps must be taken to prevent
this problem.
About this task
The restore operation removes all library client server
transactions that occurred after the point in time from the volume
inventory of the library manager server. However, the volume inventory
of the library client server still contains those transactions. New
transactions can then be written to these volumes, resulting in a
loss of client data.
Procedure
Complete the following steps after the restore:
- Halt further transactions on the library manager server:
Disable all schedules, migration, and reclamations on the library
client and library manager servers.
- Audit all libraries on all library client servers. The
audits re-enter those volume transactions that were removed by the
restore on the library manager server. Audit the library clients
from the oldest to the newest servers. Use the volume history file
from the library client and library manager servers to resolve any
conflicts.
- Delete the volumes from the library clients that do not
own the volumes.
- Resume transactions by enabling all schedules, migration,
and reclamations on the library client and library manager servers.
