HP P6000 Cluster Extension Software Administrator Guide (5697-0986, June 2011)

In addition, the service or application's FailoverPeriod value must be higher than the resource's
RestartPeriod value and both must be higher than the resource's PendingTimeout value.
Microsoft Cluster Server provides two properties to adjust state change recognition/resolution:
• IsAlive
• LookAlive
The software automatically calls the IsAlive function whenever the cluster service calls the LookAlive
function. Therefore, both functions must be set to the same value.
NOTE:
For Windows Server 2008/2008 R2, the IsAlive and LookAlive properties are replaced by the
Thorough Resource Health Check Interval and Basic Resource Health Check Interval properties.
Bouncing service or application
P6000 Cluster Extension will alternate (start and fail) between local nodes if the ApplicationStartup
property has been set to FASTFAILBACK and no remote system is available until the service or
application restart limit has been reached. For more information, see APPLICATION objects.
Administration
P6000 Cluster Extension administration includes remote management of resources and monitoring of
system resources and logs.
Remote management of P6000 Cluster Extension resources in a cluster
You can use the MMC with Failover Cluster Management to manage clusters and configure P6000
Cluster Extension resources. Note the following when configuring P6000 Cluster Extension resources
by using the MMC from a remote management station:
• When you use the MMC to remotely configure P6000 Cluster Extension resource properties in a
Server Core or Hyper-V Server cluster node, the Failover Cluster Management GUI on the remote
management station displays the standard Microsoft Properties tab instead of the customized
P6000 Cluster Extension Parameters tab. For more information about the Properties tab, see Setting
P6000 Cluster Extension resource properties using the MMC.
• When you install P6000 Cluster Extension into a Windows Server 2008/2008 R2 environment,
the resource extension DLL is registered by default, which prevents you from configuring a P6000
Cluster Extension resource from a remote management station. If you need to remotely configure
a P6000 Cluster Extension resource in a Windows Server 2008/2008 R2-based cluster, unregister
clxevamscsex.dll from the cluster node, which allows you to configure the P6000 Cluster
Extension resource using the standard Microsoft Properties tab. Use the command cluster /
UNREGADMINEXT:clxevamscsex.dll to unregister the DLL.
CAUTION:
Configuring P6000 Cluster Extension resources using the MMC from a remote management station
is supported using only the standard Microsoft Properties tab. Do not try to use the customized
P6000 Cluster Extension Parameters tab for this purpose.
