Here another quick tip: To find out all information on scsi devices linux see’s use this command:
cat /proc/scsi/scsi
Attached devices:
Host: scsi0 Channel: 00 Id: 00 Lun: 00
Vendor: ATA Model: WDC WD2500JB-22R Rev: 20.0
Type: Direct-Access ANSI SCSI revision: 05
Host: scsi0 Channel: 00 Id: 01 Lun: 00
Vendor: ATA Model: WDC WD3200JB-00K Rev: 08.0

Host: scsi2 Channel: 00 Id: 00 Lun: 00
Vendor: ATA Model: Hitachi HDP72505 Rev: GM4O

Or if you want to only see the fiber channel:
cd /proc/scsi/qla2xxx (assuming you are using a qlogic fiber card)
cat 1
cat 2
You may see different numbers under this directory representing the HBA’s this is a great way to check that your adapters see the same storage.
