Installation Credentials used for system configuration no longer valid – causing problems with node actions in HPC Cluster Manager RRS feed

  • Question

  • Hello,

    The user who originally installed and configured our Windows HPC Server 2008 cluster is no longer with the company and the installation credentials he used are no longer valid. Therefore, Node Actions in HPC Cluster Manager such as “Reboot” and “Shut Down” fail because the account is currently disabled. For some reason, the only Node Actions that do work are “Take Offline” and “Bring Online”.

    How can we correct this issue without impacting user jobs which are running successfully? How will this impact a possible upgrade in the future?

  • Hi Kent,

    Could you try to reset the install credential from the to do list via admin console and see if it works?

  • Hi Yutong,

    Thanks for the suggestion...I am fairly new to this environment and want to make sure that if we reset the install credentials that it won't negatively impact any jobs or cluster operations. Is there a danger of anything negative happening if we reset the install credentials?

    One of my colleagues states that when we upgrade the cluster from HPC Server 2008 we will do a "new" install instead of an upgrade. Is there any recommendation or documentation that you can provide for such an install and how we can avoid problems with install credentials in the future?

    Many thanks,

  • Hi Kent,

    The install credentials is used to configure new compute nodes for installing the operating system, adding nodes to the Active Directory domain, running diagnostic tests etc. Reseting the install credential doesn't have any negative impact on the cluster. Only make sure the new install credential is already in the administrators group.

    For upgrading from HPC Server 2008 to HPC Server 2008 R2, please refer to the HPC Server 2008 R2 release notes @ https://technet.microsoft.com/en-us/library/ee783542%28v=ws.10%29.aspx . I strongly recommeded to a new installation. Besides, the latest HPC Pack 2012 R2 Update 1 @ https://technet.microsoft.com/library/dn864737.aspx would be recommended.
