Hello, I am having issues to have tgtd to assume specified LUN ID numbers. I did the following procedure: tgtadm --lld iscsi --mode target --op new --tid 1 --targetname iqn.2014-09.local.vclass:tg0 tgtadm --lld iscsi --op new --mode logicalunit --tid 1 --lun 1 --backing-store /dev/sdg tgtadm --lld iscsi --op new --mode logicalunit --tid 1 --lun 2 --backing-store /dev/sdh tgtadm --lld iscsi --op new --mode logicalunit --tid 1 --lun 3 --backing-store /dev/sdi tgtadm --lld iscsi --op new --mode logicalunit --tid 1 --lun 4 --backing-store /dev/sdj tgtadm --lld iscsi --mode target --op new --tid 2 --targetname iqn.2014-09.local.vclass:tg1 tgtadm --lld iscsi --mode target --op new --tid 3 --targetname iqn.2014-09.local.vclass:tg2 tgtadm --lld iscsi --op new --mode logicalunit --tid 2 --lun 5 --backing-store /dev/sde tgtadm --lld iscsi --op new --mode logicalunit --tid 3 --lun 5 --backing-store /dev/sdf tgtadm --lld iscsi --op bind --mode target --tid 2 --initiator-address 172.20.10.61 tgtadm --lld iscsi --op bind --mode target --tid 3 --initiator-address 172.20.10.62 tgtadm --mode target --op show tgt-admin --dump > /etc/tgt/targets.conf and the tgtadm --mode target --op show output was as shown below: [root@iscsi ~]# tgtadm --mode target --op show Target 1: iqn.2014-09.local.vclass:tg0 System information: Driver: iscsi State: ready I_T nexus information: LUN information: LUN: 0 Type: controller SCSI ID: IET 00010000 SCSI SN: beaf10 Size: 0 MB, Block size: 1 Online: Yes Removable media: No Prevent removal: No Readonly: No Backing store type: null Backing store path: None Backing store flags: LUN: 1 Type: disk SCSI ID: IET 00010001 SCSI SN: beaf11 Size: 10737 MB, Block size: 512 Online: Yes Removable media: No Prevent removal: No Readonly: No Backing store type: rdwr Backing store path: /dev/sdg Backing store flags: LUN: 2 Type: disk SCSI ID: IET 00010002 SCSI SN: beaf12 Size: 10737 MB, Block size: 512 Online: Yes Removable media: No Prevent removal: No Readonly: No Backing store type: rdwr Backing store path: /dev/sdh Backing store flags: LUN: 3 Type: disk SCSI ID: IET 00010003 SCSI SN: beaf13 Size: 10737 MB, Block size: 512 Online: Yes Removable media: No Prevent removal: No Readonly: No Backing store type: rdwr Backing store path: /dev/sdi Backing store flags: LUN: 4 Type: disk SCSI ID: IET 00010004 SCSI SN: beaf14 Size: 10737 MB, Block size: 512 Online: Yes Removable media: No Prevent removal: No Readonly: No Backing store type: rdwr Backing store path: /dev/sdj Backing store flags: Account information: ACL information: Target 2: iqn.2014-09.local.vclass:tg1 System information: Driver: iscsi State: ready I_T nexus information: LUN information: LUN: 0 Type: controller SCSI ID: IET 00020000 SCSI SN: beaf20 Size: 0 MB, Block size: 1 Online: Yes Removable media: No Prevent removal: No Readonly: No Backing store type: null Backing store path: None Backing store flags: LUN: 5 Type: disk SCSI ID: IET 00020005 SCSI SN: beaf25 Size: 10737 MB, Block size: 512 Online: Yes Removable media: No Prevent removal: No Readonly: No Backing store type: rdwr Backing store path: /dev/sde Backing store flags: Account information: ACL information: 172.20.10.61 Target 3: iqn.2014-09.local.vclass:tg2 System information: Driver: iscsi State: ready I_T nexus information: LUN information: LUN: 0 Type: controller SCSI ID: IET 00030000 SCSI SN: beaf30 Size: 0 MB, Block size: 1 Online: Yes Removable media: No Prevent removal: No Readonly: No Backing store type: null Backing store path: None Backing store flags: LUN: 5 Type: disk SCSI ID: IET 00030005 SCSI SN: beaf35 Size: 10737 MB, Block size: 512 Online: Yes Removable media: No Prevent removal: No Readonly: No Backing store type: rdwr Backing store path: /dev/sdf Backing store flags: Account information: ACL information: 172.20.10.62 My intention is that all LUN IDs should be different per host, so tg0 will serves shared LUNs 1,2,3 and 4 and tg1 serves LUN 5 to host 172.20.10.61 and tg2 serves LUN 5 to host 172.20.10.62. I am using CentOS 6.5 After reboot tg1 and tg2 presents the LUNs both with LUN ID 1. Also added LUN 5 to both targets in /etc/tgt/targets.conf and after reboot ignores the instruction and still presents with LUN ID 1. /etc/tgt/targets.conf below: Default-driver iscsi backing-store /dev/sdf LUN 5 initiator-address 172.20.10.62 backing-store /dev/sde LUN 5 initiator-address 172.20.10.61 backing-store /dev/sdg backing-store /dev/sdh backing-store /dev/sdi backing-store /dev/sdj Please, can anyone be so kind and help me to fix the LUN IDs? Thank you in advance. -- 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
