A volume that shows as raw in Windows Disk Management means the file system structure on the drive is corrupted. The possible reason being the iSCSI LUN unexpectedly disconnected from the iSCSI initiator due to a network disconnection or an abnormal shutdown.

You may try to fix the file system error on the disk in question by chkdsk utility in Windows

Open Windows Command Prompt

Run the command chkdsk <drive letter>: /f (For example: chkdsk E: /f)

Note: there is still a possibility that the file system can't be repaired after running the command.
