DC_A_StorageCellWWN (Required)
Format String
Description The WWN of the EVA storage system located in data center A. This is the node
WWN value indicated in the Storage System Properties page in P6000 Command
View.
DC_B_StorageCellWWN (Required)
Format String
Description The WWN of the EVA storage system located in data center B. This is the node
WWN value indicated in the Storage System page in P6000 Command View.
DeviceGroup (Required)
Format String
Description EVA Continuous Access DR group, containing the application service disk set.
FailsafeMode (Optional)
Format String
Description Specifies the failsafe mode configured for the DR group. Use this object to ensure
that your configurations are supported based on consistency considerations. Different
failover and recovery procedures are used for different failsafe modes. If you change
the FailsafeMode object value, review the value of the FailsafeModeOverride object.
This property applies to synchronous DR groups only.
NOTE: P6000 Command View displays two failsafe modes for the EVA4400. The
FailSafeMode property in EVA Cluster Extension corresponds to Failsafe on
unavailable member on the EVA4400. See the P6000 Command View
documentation for more details.
Valid values Disabled (default)
Enabled
FailsafeMode Override (Optional)
Format String
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
Description Specifies the check interval (in seconds) for checking the status of the DR
group synchronization (merging). It might take a while to synchronize member
vdisks. You can set this value if the ApplicationStartup property is set to
RESYNCWAIT.
