Verifying new device recognition
1. Verify that the HBA driver is installed using the lsmod command.
2. View the device information in the /proc/scsi/scsi file.
Example
#cat /proc/scsi/scsiAttached devices:
Host: scsi0 Channel: 00 Id: 00 Lun: 00
Vendor: HP Model: OPEN-9 Rev: 2105
Type: Direct-Access ANSI SCSI revision: 02
Host: scsi0 Channel: 00 Id: 00 Lun: 01
Vendor: HP Model: OPEN-9 Rev: 2105
Type: Direct-Access ANSI SCSI revision: 02
Host: scsi0 Channel: 00 Id: 00 Lun: 02
Vendor: HP Model: OPEN-9 Rev: 2105
Type: Direct-Access ANSI SCSI revision: 02
Host: scsi0 Channel: 00 Id: 00 Lun: 03
Vendor: HP Model: OPEN-9 Rev: 2105
Type: Direct-Access ANSI SCSI revision: 02
3. Verify that the system recognizes the disk array partitions by viewing the /proc/partitions
file.
Example
#cat /proc/partitions

In the above example, the “sd” devices represent the XP disk partitions and the “cciss” devices
represent the internal hard drive partitions on an HP Proliant system.
