You need to configure WWPNs under /qla2xxx from within the shell, the available qla2xxx target WWPN are shown via: /> qla2xxx/ info Fabric module name: qla2xxx ConfigFS path: /sys/kernel/config/target/qla2xxx Allowed WWNs list (free type): 21:00:00:24:ff:31:4c:49, 21:00:00:24:ff:31:4c:48 Fabric module specfile: /var/target/fabric/qla2xxx.spec Fabric module features: acls Corresponding kernel module: tcm_qla2xxx You'll need to create explict NodeACLs for FC Initiator WWPNs in order for initiators to see WWPN LUNS. So for example, in order for FC Initiator 21:00:00:24:ff:31:4c:4d to access LUN=[0,1] on FC Target WWPN 21:00:00:24:ff:31:4c:48, your configuration should look like: /> ls qla2xxx/21:00:00:24:ff:31:4c:48/luns/ o- luns ............................................................... [2 LUNs] o- lun0 ........ [iblock/scsi_debug1 (/dev/disk/by-id/wwn-0x5001517959269ed1)] o- lun1 ............................................ [iblock/fioa (/dev/fioa)] /> ls qla2xxx/21:00:00:24:ff:31:4c:48/acls/ o- acls ............................................................... [2 ACLs] o- 21:00:00:24:ff:31:4c:4d ................................... [2 Mapped LUNs] o- mapped_lun0 ................................................. [lun0 (rw)] o- mapped_lun1 ................................................. [lun1 (rw)] /> The only part that's not TAB completable currently in the shell is adding the FC Initiator WWPNs for the NodeACL, and these do need to be formatted according to the filter in /var/target/fabric/qla2xxx.spec, eg: cat /sys/class/fc_host/host*/port_name | sed -e s/0x// -e 's/../&:/g' -e s/:$// --nab > acls ...............................................................................................
