Field Tips
Switchback
Type
You must select intelligent switchback. This means that after a
failover to the backup server, an administrator must manually switch
the Multi-Site Cluster resource back to the primary server.
CAUTION: This release of SteelEye DataKeeper does not support
Automatic Switchback for DataKeeper resources. Additionally, the
Automatic Switchback restriction is applicable for any other
LifeKeeper resource that becomes part of the Multi-Site Cluster
hierarchy. This includes anything sitting above the hierarchy or
becomes a child within the hierarchy.
Server
Select the name of the server where the NetRAID device will be
created (typically this is your primary server). All servers in your
cluster are included in the drop down list box.
