Virtual TapeServer 8.3 Configuration Guide

90 | Virtual TapeServer Configuration Guide
l You must set the Trigger Policy If Enabled option when configuring jobs; jobs are responsible
for performing policy actions. For example, a replication jobs and a stacked export job must
exist and the Trigger Policy If Enabled option must be set on the jobs to accomplish the
scenario described above.
l You cannot create multiple policies that are initiated by the same event for the same pool. For
example, you cannot replicate and export a tape in PoolA after the tape is unmounted.
l You cannot define different policy attributes if multiple policies trigger the same action for the
same pool. For example, you cannot replicate to HostA and HostB after tapes in PoolA are
unmounted.
l Be careful not to create "circular" policies, such as if PolicyA triggers a stacked export after
replication and PolicyB triggers replication after a stacked export. These policies will trigger
each other indefinitely.
l If a policy is disabled, it cannot trigger actions. You must enable a policy to allow VTS to
perform an action after the specified event occurs.
Events that trigger policy actions
l export (by tape-to-tape or stacked export job)
l replication
l import (from a tape device or replication target)
l encryption
l decryption
l unmount
Note that an event must complete successfully to trigger a policy action.
Actions that can be triggered
l stacked export
l tape-to-tape export
l replication to a target
l remote export
l mount
l encryption
l erasure
l import from a tape device
l import from a replication target
Before beginning
l Create one or more pools to which the policy can be applied.
