ctl_isc_lun_sync: Received conflicting HA LUN

[Mikhail Zakharov]

Yes, there is misunderstanding. 
CTL HA setup works for 2 different servers that are accessing right the same drive. It is not like HAST. So if you need replication to a different drive, use HAST, but if you want simultaneous access to the single drive, use CTL HA.

Best regards,
Mike
