HP XP Cluster Extension Software Administrator Guide
remote data center are considered DOWN. If the swap-takeover operation leads
to a suspended state for the device/copy group, the Continuous Access links are
considered DOWN.
Because redundant networks and Continuous Access links are necessary to build a
disaster-tolerant environment, this situation can be considered as a data 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 disk status
information can be gathered. If the remote 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, HP XP Cluster
Extension will attempt to recover the PAIR state for the device/copy group. HP XP
Cluster Extension waits until the PAIR state has been established. If this operation
fails, HP 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/copy 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)
