Hannes and co, these patches looks fine to me.. The plan on my side to is start testing the scsi_dh_alua client changes againt the lio-core-2.6.git implict ALUA logical unit group and target port group bits for v2.6.30. Getting the initial optimized <-> non optimize ALUA state transitions up should be done in the next weeks for you to poke at seriously against your scsi_dh_alua nodes using Open/iSCSI. Also from there the first explict ALUA using MO_SET_TARGET_PGS. >From there target_core_mod PR and ALUA fabric against OpenFCoE target ports and all sorts of Linux Cluster clients is not too far away. :-) --nab > > Signed-off-by: Hannes Reinecke <hare@xxxxxxx> -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
