4. Select the LUN Access mode as R/W, SR/W, RO, or IRO.
R/W: Read and writing permission.
IRO (Intelligent Read Only): Even though writing operation succeeded, data wouldn’t be written into
LUN. It is mainly used to test storage system’s performance.
RO: Read only
SR/W (Synchronous Read/Write): It writes the data into disks directly without writing into disk buffer.
A low writing speed makes the data complete.

When multiple iSCSIs share the same LUN, only one iSCSI server’s access mode can be R/W and other servers
should be RO or IRO, or file system may be damaged or data may lose.
