Header and Data Error Detection?

Hello,
I am using globalSAN iSCSI initiator, when I create targets and then connect to them in globalSAN on my OSX machines i get a Warning message:
"Header and Data Error Detection setting was not applied on the target. This may potentially lead to data corruption. It is reccomended to set the values of HeaderDigets and DataDigest ISCSI parameters on the target to 'CRC32C'.
What can I do to rectify this, and can i alter these parameters within starwind?
thanks
Brucifer

With modern converged loss-less Ethernet networks, strong hashes on target side applied to data blocks and controller-level redundancy most of old iSCSI-related attempts to keep data integrity and connection recovery (digests, CRCs and ERL higher then zero) are outdated and don't have much of sense. So... Simply ignore.
