output of lspci -v? The marking of LUN 2, how does it exactly appear in /sys/class/scsi_device/? GM Michal Ludvig wrote:
Hi all, I've got RHEL5.3 (x86) server with dual-port QLA2342 HBA (kernel module qla2xx) connected using FibreChannel to HP VA7410 disk array, one HBA port to each of the two SAN controllers. I've got three LUNs created on the array: LUN 0: Capacity: 1.0 GB RGID: 1 LUN 1: Capacity: 301.4 GB RGID: 1 LUN 2: Capacity: 100.0 GB RGID: 2 RGID is a "redundancy group" - RGID 1 is "owned" by the first SAN controller, RGID 2 by the second ctrlr. However when I modprobe qla2xxx only LUN0 and LUN1 are attached as disks (sd). LUN2 is attached as 'scsi' and not accessible as a disk. The system knows that it exists, because there is an entry in /sys/class/scsi_device/ but is no accessible as a block device. This is the relevant 'dmesg' output: QLogic Fibre Channel HBA Driver ACPI: PCI Interrupt 0000:02:02.0[A] -> GSI 35 (level, low) -> IRQ 74 qla2xxx 0000:02:02.0: Found an ISP2312, irq 74, iobase 0xd0040000 qla2xxx 0000:02:02.0: LIP reset occured (f82b). scsi1 : qla2xxx qla2xxx 0000:02:02.0: LIP occured (f82b). qla2xxx 0000:02:02.0: LOOP UP detected (2 Gbps). qla2xxx 0000:02:02.0: QLogic Fibre Channel HBA Driver: 8.02.00.06.05.03-k QLogic QLA2342 - 133MHz PCI-X to 2Gb FC, Dual Channel ISP2312: PCI (66 MHz) @ 0000:02:02.0 hdma-, host#=1, fw=3.03.26 IPX ACPI: PCI Interrupt 0000:02:02.1[B] -> GSI 34 (level, low) -> IRQ 82 qla2xxx 0000:02:02.1: Found an ISP2312, irq 82, iobase 0xd0042000 qla2xxx 0000:02:02.1: LIP reset occured (f827). scsi2 : qla2xxx qla2xxx 0000:02:02.1: LIP occured (f827). qla2xxx 0000:02:02.1: LOOP UP detected (2 Gbps). qla2xxx 0000:02:02.1: QLogic Fibre Channel HBA Driver: 8.02.00.06.05.03-k QLogic QLA2342 - 133MHz PCI-X to 2Gb FC, Dual Channel ISP2312: PCI (66 MHz) @ 0000:02:02.1 hdma-, host#=2, fw=3.03.26 IPX Vendor: HP Model: A6218A Rev: A140 Type: Direct-Access ANSI SCSI revision: 03 Vendor: HP Model: A6218A Rev: A140 Type: Direct-Access ANSI SCSI revision: 03 SCSI device sdb: 2097152 512-byte hdwr sectors (1074 MB) sdb: Write Protect is off sdb: Mode Sense: af 00 10 08 SCSI device sdb: drive cache: write back w/ FUA sdb: unknown partition table sd 2:0:0:0: Attached scsi disk sdb Vendor: HP Model: A6218A Rev: A140 Type: Direct-Access ANSI SCSI revision: 03 SCSI device sdc: 632164352 512-byte hdwr sectors (323668 MB) sdc: Write Protect is off sdc: Mode Sense: af 00 10 08 SCSI device sdc: drive cache: write back w/ FUA sdc: sdc1 sd 2:0:0:1: Attached scsi disk sdc Vendor: HP Model: A6218A Rev: A140 Type: Direct-Access ANSI SCSI revision: 03 kjournald starting.

I tried all ports on the array as well as swapped the cables on HBA, so a HW problem of this type is unlikely. Any ideas what's wrong? Thanks! Michal
