A physical disk resource may unexpectedly fail or go offline when the IsAlive function is executed on a Windows Server 2008 cluster nodeArticle ID: 953652 - View products that this article applies to. On This PageSYMPTOMSConsider the following scenario:
CAUSEWhen the IsAlive function is run while a file in the root folder of a Windows Server 2008
cluster node is
being accessed,
the logic of the IsAlive function is incorrect. For example, Microsoft
SQL Server
and Microsoft
Exchange Server may store temporary files in the root
folder, and
these files are frequently created and deleted. If
these temporary files are accessed while the IsAlive function is being called, the disk resource and any dependent
resources may encounter a failed state. This
triggers the cluster service restart logic. RESOLUTIONHotfix informationA supported hotfix is available from Microsoft.
