Could someone tell me the answer. There may be several of them and brief explanation. What I know is that this should be basic disk.
Thanks a lot!

    Hi,

    The cluster witness disk must be a cluster disk, so the cluster disk condition needs to be met cluster disk requirements.

    It must be dedicated LUN that stores a copy of the cluster database, fc lun and iscsi lun is normal cluster disk witness.

    For more information, please see:

    Best Regards,
    Daniel

    A quorum disk is disk shared among all nodes of a cluster and is defined as a cluster disk. It can be connected in any manner, FC, iSCSI, SCSI, SAS, etc., that a cluster allows. It is not a CSV; just a cluster disk. It needs to be at least 512 MB in size. It is dedicated, i.e. you cannot use it for any other purpose within the cluster. There is no need to assign a letter to it; in fact, it is best not to assign a letter lest someone inadvertently try to use that letter for some purpose.
