    Can you provide additional details about your storage and if possible attach a vmkernel.log from the host that experienced disconnection.

    Hi Richard,

    Good day to you and sorry late to updates.

    - we use the IBM Storwize V7000 and Storwize V7000 Unified Disk Systems.

    - I can not find the file VMkernel on ESXi 6.0 host that experienced disconnection. but I take the summary logs of the ESXi experienced disconnect.

    Please find the information below :
