2. Verify that the iSCSI exported volumes have been discovered.
# cat /proc/scsi/scsi

Discovering Devices with RHEL 4
Complete the following steps to discover devices with an iSCSI connection on the RHEL 4 Host:
1. On the RHEL 4 iSCSI Initiator host, use the iscsi-rescan command to rescan for the newly
exported LUN:
# iscsi-rescan
Rescanning host10
Rescanning host11
2. Use the iscsi -ls command to display the scanned iSCSI devices.
3. Verify the contents of /proc/scsi/scsi for the new device:
# cat /proc/scsi/scsi
Attached devices:
Host: scsi2 Channel: 00 Id: 00 Lun: 00
