2. Update the ApplicationStartup and AutoRecover values as needed, and then click OK.
3. Click OK to save your changes and close the Properties window or Resource Configuration
tool.
Activating the pair/resync monitor
The pair/resync monitor detects and responds to suspended Continuous Access links if the
ResyncMonitor object is set to YES. If the ResyncMonitorAutoRecover object is set to YES, automatic
disk pair resynchronization is also activated.
When the resource is taken offline, the monitor is stopped for the RAID Manager device/copy
group used for this resource.
CAUTION:
If a resource cannot be taken offline manually, and goes into a failed state, the cluster administrator
must disable monitoring of the device/copy group for this resource. To avoid data corruption, this
task must be part of the recovery procedure when P9000 Cluster Extension is deployed in an MSCS
environment. See “Stopping the pair/resync monitor” (page 73).
You must ensure that the pair/resync monitor does not monitor and resynchronize the disk pair
(device/copy group) from both disk array sites.
To activate the pair/resync monitor from the Failover Cluster Management Parameters tab or the
resource configuration tool:
1. Click Pair ResyncMon to open the Pair/Resync Monitor Properties window.
2. Select the Use pair/resync monitor check box to set the ResyncMonitor object to YES.
3. Select the Pair/resync monitor autoRecovery check box to set the ResyncMonitorAutoRecover
object is to YES.
4. If you want to change the monitoring interval (ResyncMonitorInterval), enter a value in the
Monitor interval box.
5. Click OK to save your changes and close the Pair/Resync Monitor Properties window.
6. Click OK to save your changes and close the Properties window or Resource Configuration
tool.
TIP: You can activate ResyncMonitor from the Microsoft CLI. For example, if your P9000 Cluster
Extension resource is clx_fileshare, enter the following command: C:\>cluster resource
clx_fileshare /privprop ResyncMonitor=yes.
Configuring takeover actions
Pre-executables and post-executables can be defined to be executed before or after P9000 Cluster
Extension invokes its takeover functions.
