    Hello there,

    There are definitely some connectivity issues between that one host and the SAN that lead to iSCSI connection instability and following storage I/O delays. Are you using multiple network connections from each server?

    Have you checked the Event Viewer for any trace?

    If you cannot find anything in Event Viewer I would suggest you use tools like Procmon to find the root cause for this behaviour.

    Hope this resolves your Query !!

    The issue might be related to network connectivity to a shared storage. It could be also related to a shared storage issues.

    I would recommend you to check Event logs and connectivity to your SAN.

    You can test your iSCSI network using an alternative options. StarWind VSAN can be used to create iSCSI storage for your cluster.
