Lock by third-party monitoring tools on shared volumes

Some third-party monitoring tools (such as Compaq Insight Manager) hold an exclusive lock or have an open file handle on the shared volumes they monitor. This lock may prevent VCS from offlining a service group that includes the volume as a resource. VCS requires a lock on resource in a service group when taking the group offline.

Workaround: Arctera recommends adding a custom resource as the topmost parent for an affected service group. Use the custom resource to manage onlining, monitoring, and offlining of the third-party monitoring tool.
