HP StorageWorks EVA Cluster Extension Software Administrator Guide (T3667-96045, April 2010)

Description Specifies whether EVA Cluster Extension can disable the failsafe mode configured
for the DR group during a failover, if necessary. This property is used only if
FailsafeMode is enabled for the DR group. Disabling FailsafeMode might leave
the data at the destination site in a noncurrent state; setting FailsafeModeOverride
to YES provides the highest level of data availability with the compromise of data
currency at the destination site. This property applies to synchronous DR groups
only.
Valid values NO (default)
YES
MergeCheckInterval
Format Integer
Descrip-
tion
Specifies the check interval (in seconds) for checking the status of the DR group synchron-
ization (merging). It might take a while to synchronize member vdisks. You can set this
value if the ApplicationStartup property is set to RESYNCWAIT.
Default
value
20
PostExecCheck (Optional)
Format String
Description The PostExecCheck object is used to configure EVA Cluster Extension to gather EVA
disk pair status information after the takeover procedure. That information will be
passed to the post-executable. In case of a remote data center failure, it could be
time consuming to gather that information, especially if your post-executable does
not need any EVA status information. The arguments passed to the post-executable
will include only the local disk status if the PostExecCheck object is set to NO.
Valid values YES
NO (default)
PostExecScript (Optional)
Format String
Description Specifies an executable with its full path name to be invoked after the failover action
or failover procedure.
You can include environment variables in path names.
Do not specify arguments to be passed to the executable.
PreExecScript (Optional)
Format String
