  • 1.  3 Datastores have become unmountable on all hosts

    Posted Aug 16, 2020 06:13 PM

    Hi community

    I have a large VMWare esxi environment with multiple hosts and clusters and multiple datastores.

    3 of my datastores have suddenly become unmountable\inaccessible.

    I have made sure the mapping and zoning on the storage is correct and all the hosts are mapped to all the datastores.

    I dont know what else i can do to access these datastores again. I have multiple VMs that are now also inaccessible because of this and I cannot migrate them or do anything at all to bring them back online

    If this is a production business environment, you should be opening a support request with GSS right about now.

    Check vmkernel.log when  executing  esxcfg-rescan -A.   Post the active lines of the log here.
