Enable clustered access to
the iSCSI target from multiple
initiators
When enabled, multiple iSCSI initiators can access this target and its LUNs
simultaneously.
Warning
To prevent data corruption, the initiators and LUN
filesystems must all be cluster-aware.
CRC/Checksum Initiators and targets communicate over TCP connections using iSCSI
protocol data units (PDU). The sending device can send a checksum with
each PDU. The receiving device uses this checksum to verify the integrity of
the PDU, which is useful in unreliable network environments. There are two
checksum types, which can be enabled separately.
• Data Digest: The checksum can be used to verify the data portion of
the PDU.
• Header Digest: The checksum can be used to verify the header portion
of the PDU.
