center failure. The DataLoseDataCenter object is used to allow/prohibit automatic
application service startup in this particular case.
The combination of setting the DataLoseMirror object to YES and the
DataLoseDataCenter object to NO are contradictory.
Valid values YES (default)
NO
DataLoseMirror
Format String
Description (Optional) Specifies whether a resource should be brought online while the disk
pair is suspended or deleted.
Used only if the FenceLevel object value is DATA and local and remote XP disk
status information can be gathered. If the remote XP disk state information is not
available (remote state EX_ENORMT), the setting of the DataLoseDataCenter object
will be used.
Depending on the value configured for the AutoRecover object, XP Cluster Extension
will attempt to recover the PAIR state for the device group. XP Cluster Extension
waits until the PAIR state has been established. If this operation fails, XP Cluster
Extension returns a global error. Because the DATA fence level ensures no loss of
concurrency, manual intervention is required to recover the PAIR state. The PAIR
state must be re-established for all disks in the device group before you can start
the application service.
The combination of setting the DataLoseMirror object to YES and the
DataLoseDataCenter object to NO are contradictory.
Valid values YES
NO (default)
