Oops - I should have been clearer.
I'm talking about an iSCSI connection. In the target, I enabled CRC for both Header and Data, but I get an error when I connect to the target using the MS iSCSI initiator.
Yes we do support this. Go to the Console and enter CTRL + ALT + W then Tuning options then iSCSI daemon options and target options. Select the Target of choice then you will see to enable the Data and Header Digest. Enable the CRC32C and reconnect from the MS initiator.
