Microsoft exchange 2003 Cluster failed RRS feed

  • Question

  • Hello everyone

    I have a Windows 2003 failover cluster for MS exchange 2003. After some updates, I lost access to all physical disk resources, including Quorum partition. I folowed the official MS procedure to restore the resources, but it failed.

      The hard-disks are FC HDDs from EMC VNX 5500 storage. In disk management, I am able to see the disks, but in Windows Explorer i don't have access to the disks (F:\ is not accessible). If I try to remove HDD resources from cluster i get an error (probabily because Cluster service is down).

     Does anyone know how to manualy unlock resources from MS Cluster ??? Or how can I get access to the mailbox databases to try to restore the mailbox data on another server?

    Thank you

  • Hi ddamq,

    Since Exchange server 2003 has been out of support, I suggest migrate to Exchange 2007/2010/2013 or Office 365 so that you can get more professional support.

    I have searched on Technet, and get following articles:

    1. Failover and failback

    2. Initiate a resource failure

    More detailed steps to manually failover as below:

    • Open Cluster Administrator.
    • In the console tree, click the Groups folder, and then click the group that contains the resource to fail.
    • In the details pane, click the resource you want.
    • On the File menu, click Initiate Failure.

    Additionally, I notice that you want to unlock resources from Cluster. 

    Please verify whether you type chkdsk /f on a disk, if it is the case, the disk is locked for exclusive use to examine the consistency of the disk.
