HP StorageWorks P9000 Cluster Extension Software Administrator Guide (TB534-96009, February 2011)

Bouncing service or application
P9000 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 “ApplicationStartup” (page 84).
The FastFailbackEnabled property is not used by the P9000 Cluster Extension integration with
MSCS.
Administration
P9000 Cluster Extension administration includes remote management of resources and monitoring
of system resources and logs.
Remote management of P9000 Cluster Extension resources in a cluster (Windows
Server 2008/2008 R2)
You can use the MMC with Failover Cluster Management to manage clusters and configure P9000
Cluster Extension resources. Note the following when configuring P9000 Cluster Extension resources
by using the MMC from a remote management station:
• When you use the MMC to remotely configure P9000 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 P9000 Cluster Extension Parameters tab. For more information about the Properties
tab, see “Setting P9000 Cluster Extension resource properties using the MMC” (page 42).
• When you install P9000 Cluster Extension into a Windows Server 2008/2008 R2 environment,
the resource extension DLL is registered by default, which prevents you from configuring a
P9000 Cluster Extension resource from a remote management station. If you need to remotely
configure a P9000 Cluster Extension resource in a Windows Server 2008/2008 R2-based
cluster, unregister clxmscsex.dll from the cluster node, which allows you to configure the
P9000 Cluster Extension resource using the standard Microsoft Properties tab. Use the command
cluster /UNREGADMINEXT:clxmscsex.dll to unregister the DLL.
CAUTION: Configuring P9000 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 P9000 Cluster Extension Parameters tab for this purpose.
• If you see the customized P9000 Cluster Extension Parameters tab when you try to configure
a P9000 Cluster Extension resource from a remote management station using the MMC, you
must unregister clxmscsex.dll from the cluster node. Use the command cluster
/UNREGADMINEXT:clxmscsex.dll to unregister the DLL. Unregistering the DLL allows you
to configure the resource using the standard Microsoft Properties tab. This situation might
occur if you have a cluster with both Server Core or Hyper-V Server and Windows Server
2008/2008 R2 cluster nodes.
• When you configure P9000 Cluster Extension resource properties from a remote management
station through the MMC, which uses the standard Microsoft Properties tab, the properties
you enter are not validated, so you must enter the property values accurately, and verify them
against the P9000 Cluster Extension documentation.
