Hi all I'm using RHEL 6.1 (fully patched, 2.6.32-131.12.1.el6.x86_64 with iscsi-initiator-utils-6.2.0.872-21.el6.x86_64) on HP BL460c G7 blades talking to a P4500 14.4TB Virt SAN (two clustered P4500 boxes).
As the blade has two FlexHBA (iSCSI) interfaces I want to do multipathing. Is the following valid? (Spefically, should both ifaces have the same iqn?) --- iscsiadm -m iface default tcp,<empty>,<empty>,<empty>,<empty> iser iser,<empty>,<empty>,<empty>,<empty> be2iscsi.00:17:a4:77:10:01 be2iscsi, 00:17:a4:77:10:01,<empty>,<empty>,iqn.2011-08.scada.benvir2p be2iscsi.00:17:a4:77:10:00 be2iscsi, 00:17:a4:77:10:00,<empty>,<empty>,iqn.2011-08.scada.benvir2p --- In this setup, I can only login to the LUN on iface be2iscsi. 00:17:a4:77:10:01. When I attempt to login with the other iface I get 'iscsiadm: No records found'. I have other servers where I'm only using a single FlexHBA (be2iscsi) and they are having their own troubles. For example, dmesg is reporting lots of: --- scsi: host 0 channel 0 id 0 lun4194304 has a LUN larger than allowed by the host adapter device-mapper: table: 253:7: multipath: error getting device device-mapper: ioctl: error adding target to table device-mapper: table: 253:7: multipath: error getting device device-mapper: ioctl: error adding target to table scsi: host 0 channel 0 id 0 lun4194304 has a LUN larger than allowed by the host adapter device-mapper: table: 253:7: multipath: error getting device device-mapper: ioctl: error adding target to table device-mapper: table: 253:7: multipath: error getting device device-mapper: ioctl: error adding target to table --- cat /proc/scsi/scsi Attached devices: Host: scsi0 Channel: 00 Id: 00 Lun: 00 Vendor: HP Model: P410i Rev: 3.66 Type: RAID ANSI SCSI revision: 05 Host: scsi0 Channel: 00 Id: 00 Lun: 01 Vendor: HP Model: LOGICAL VOLUME Rev: 3.66 Type: Direct-Access ANSI SCSI revision: 05 Host: scsi1 Channel: 00 Id: 00 Lun: 00 Vendor: LEFTHAND Model: iSCSIDisk Rev: 9000 Type: Direct-Access ANSI SCSI revision: 05 cat /proc/partitions major minor #blocks name 8 0 586029016 sda 8 1 512000 sda1 8 2 585515008 sda2 253 0 2097152 dm-0 253 1 50331648 dm-1 253 2 4194304 dm-2 253 3 4194304 dm-3 253 4 4194304 dm-4 253 5 4194304 dm-5 8 16 1073741824 sdb 253 6 1073741824 dm-6 This is all standard data iSCSI, I'm not attempting to do iSCSI booting at all. I've been trying to make this work for a while now and I'm wondering if I should just use software iSCSI?
