FastFailbackEnabled (VCS only)
Format String
Description (Optional) Disables VCS service groups for the data center. This allows the immediate
transferring of the service group back to the remote data center. To allow this
operation, the VCS configuration file (main.cf) will be write-enabled and saved
later.
The service group will be disabled for all systems contained in either the
DC_A_Hosts object or DC_B_Hosts object. Then, the VCS configuration file will
be saved (dumped).
Valid values YES (default)
NO
FenceLevel
Format String
Description (Optional) The FenceLevel object specifies the fence level configured for the device/
copy group. P9000 Cluster Extension checks whether the current fence level reported
by the disk array is the same as the configured (expected) fence level. This object
is also used to make sure your configurations are supported based on consistency
considerations. Different failover and recovery procedures are used for different
fence levels.
If you change the FenceLevel object value, also review the values of these objects:
DataLoseMirror, DataLoseDataCenter, and AsyncTakeoverTimeout.
Valid values DATA
NEVER (default)
ASYNC (This is for Journal fence level).
Filesystems (CLI and HACMP only)
Format List
Description Space-separated list of file systems.
JournalDataCurrency
Format String
Description (Optional) Specifies whether a resource should be brought online while there could
still potentially be a large amount of data on P-VOL Journal that cannot be transmitted
to the secondary site due to the Continuous Access link being down.
Used only if the FenceLevel object value is ASYNC and the local device is an S-VOL.
P9000 Cluster Extension checks whether the current Continuous Access link status
is >0 using the minimum active paths (MINAP) value returned by the RAID Manager
pairvolchk command. If the minimum active paths equals 0, this indicates that
the Continuous Access link is unavailable and that any data still located in the
primary journal will not be replicated to the secondary volume. If JournalDataCurrency
is set to YES then P9000 Cluster Extension will not perform the takeover operation
and will not allow the application to access the data.
Valid values YES (default)
NO
