Default

300 seconds
UseNonCurrentDataOk (Optional)
Format String
Description When the replication link is down, this property specifies whether HP 3PAR Cluster
Extension can fail over to the destination site when the data at the destination site
might not be current.
If a HP 3PAR Remote Copy link goes down, and the resource is moved to the remote
data center:
• Setting this value to YES means that, regardless of whether or not the data is
current in the remote data center, the resource will come online.
• Setting this value to NO means that the resource will not come online on the
remote data center since data might not be current.
Valid values YES (default)
NO
Sample configuration file
The following is a sample UCF.cfg file:
COMMON
#LogLevel info # error|info default: error (optional)
#HP3PARCLICommandTimeout 60
#HP3PARRCPeriodicLinkDownTimeout 250
# The APPLICATION part defines failover information for the application specified
# as value of the APPLICATION tag. For example, the command - clx3PARrun CLXSer -
# will use the below settings to check and allow access to the disk set specified
# as volume Group CLX_VG.
# Necessary object when clx3PARrun is used are:
# APPLICATION, DC_A_InServStorage_SerNum, DC_B_InServStorage_SerNum,
#RCVolumeGroupA, RCVolumeGroupB, DC_A_Hosts and DC_B_Hosts
APPLICATION CLXSer # package/service/cluster group test_application
DC_A_InServStorage_SerNum 1302871 # 1302871 is the data center A HP 3PAR
array serial number
#DC_B_InServStorage_SerNum 1302835 # 1302835 is the data center B HP 3PAR
array serial number
#RCVolumeGroupA CLX_VG # CLX_VG is the data center A HP
3PAR Remote Copy volume group name
#RCVolumeGroupB CLX_VG.r2835 # CLX_VG.r2835 is the data
center B HP 3PAR Remote Copy volume group name
#DC_A_Hosts clx_node1 clx_node2 # clx_node1, clx_node2 are data centre A cluster
nodes
#DC_B_Hosts clx_node3 clx_node4 # clx_node3, clx_node4 are data centre B cluster
nodes
#ApplicationStartup resyncwait # values: fastfailback | resyncwait # Setting the
fastfailback property will behave as resyncwait property when clx3parrun is used
#UseNonCurrentDataOk yes # values: yes | no #Default value is yes which causes the
failover operation to succeed at the destination site when the data at the
destination site might not be current. On setting the value to No the resource
will not come online at the destination site since the data might not be current.
NOTE:
• When you configure a UCF file, remove the # symbol for the properties you want to configure.
• CLX property name and values are case sensitive.
