Switch a Volume from iSCSI to Fibre Channel Protocol

Before changing access to a volume from iSCSI to Fibre Channel protocol:
  • You must quiesce any applications on the host that access the volume.
  • You must also disconnect the volume from hosts. This ensures that all I/O to the volume has been stopped, thus ensuring data consistency.
A volume can be accessed by only one protocol at a time. You can switch the protocol by which a volume is accessed if both protocols are enabled for a group. Hosts lose volume access during the switch.
  1. Remove ACL records from the volume.
    vol --removeacl vol_name

    Repeat for each ACL and initiator group associated with the volume.

  2. Configure Fibre Channel initiator groups and ACLs.
    See Fibre Channel Initiator Groups and Initiator Group Access Control Lists.

From the hosts, perform a target rescan to be sure the hosts discover the volume.
