• The Data Protector client is installed in a cluster. The Cell Manager (if not installed
in the cluster) in such a case is not fault tolerant; the operations in the cell must
be restarted manually.
The behavior of the Cell Manager after the failover is configurable as far as the
backup session (failed due to the failover) is concerned - the failed session can be:
• restarted as a whole
• restarted only for the failed objects
• not restarted at all
For more information on backup session behavior options on failover of the Data
Protector Cell Manager, see the online Help index: "cluster, backup specification
options".
