Switch a Volume from Fibre Channel to iSCSI Protocol

Before changing access to a volume from Fibre Channel to iSCSI 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 all Fibre Channel ACL records from the array group.
    vol --removeacl vol_name

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

  2. Configure iSCSI initiator groups and ACLs.
    See iSCSI Initiator Groups and Initiator Group Access Control Lists.
  3. Verify hosts can discover and log in to iSCSI targets.
  • From the hosts, perform a target rescan to be sure the hosts discover the volume.
