I have check event log error report eventid: 5142, 5120

Cluster Shared Volume 'Volume1' ('Cluster Disk 1') has entered a paused state because of '(c000020d)'. All I/O will temporarily be queued until a path to the volume is reestablished.

I have manually checked bring online csv disk, online, it took about 5 minutes to return the disk back to offline and reported the error as above.

I think the reason for the error is due to one of the Windows 2012R2 March 2021 updates.

    Hi,

    How do the Cluster nodes connect to the storage, ISCSI, FC, or others?

    If we use ISCSI connection, please check if the ISCSI is connected after nodes restart.

    Check if the storage server is online and the network connection between the cluster nodes and the storage is well.

    Thanks for your time!
    Best Regards,
    Anne
