Hello, I have a problem with detecting logical volumes on Compaq Raid Array 4x00 which is connected to my server via Emulex LP8000 Fibre Channel card and FC hub. System is CentOS 4 with kernel 2.6.9 (=RHEL4 clone) I get the following messagen in syslog scsi8 : Emulex LightPulse LP8000 1 Gigabit PCI Fibre Channel Adapter on PCI bus 04 device 20 irq 5 scsi: unknown device type 12 Vendor: COMPAQ Model: ARRAY CONTROLLER Rev: 2.54 Type: RAID ANSI SCSI revision: 00 scsi: unknown device type 12 Vendor: COMPAQ Model: ARRAY CONTROLLER Rev: 2.60 Type: RAID ANSI SCSI revision: 00 The result of discussion in lpfc forum is that there should be a problem the scanning part of SCSI layer. The detected devices should look like the folling output (these messages are from the same system booted into RHEL3 clone (Whitebox, kernel 2.4) with the arrays attached via Compaq FC card). kernel: Starting timer : 0 0 kernel: Vendor: COMPAQ Model: LOGICAL VOLUME Rev: 2.60 kernel: Type: Direct-Access ANSI SCSI revision: 02 kernel: Starting timer : 0 0 kernel: Vendor: COMPAQ Model: LOGICAL VOLUME Rev: 2.60 kernel: Type: Direct-Access ANSI SCSI revision: 02 kernel: Starting timer : 0 0 kernel: Vendor: COMPAQ Model: LOGICAL VOLUME Rev: 2.54 kernel: Type: Direct-Access ANSI SCSI revision: 02 kernel: Starting timer : 0 0 kernel: Attached scsi disk sda at scsi2, channel 0, id 0, lun 0 kernel: Attached scsi disk sdb at scsi2, channel 0, id 0, lun 1 kernel: Attached scsi disk sdc at scsi2, channel 0, id 1, lun 0 Thank you Dan Horak - : 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
