scsi0 and scsi1 refer to the HBA adapter instances (/proc/scsi/qla2xxx/0 and
/proc/scsi/qla2xxx/1, respectively). The Id refers to the HP 3PAR StoreServ Storage target
port (there are four HP 3PAR StoreServ Storage target ports: Id 0,1, 2, 4).
Discovering Devices with an iSCSI Connection
If the rescan-scsi-bus.sh method fails, complete the following steps to discover devices with
an iSCSI connection on the SUSE Enterprise Linux Host:
NOTE: When VLUNs are exported, they will not appear on the host automatically. After a new
VLUN is exported from an HP 3PAR StoreServ Storage iSCSI port, rescan for new LUNs.
1. Scan for new LUNs using the echo command “- - -” > /sys/class/iscsi_host/
host<host_instance>/scan”.
# echo "- - -" > /sys/class/scsi_host/host1/scan
2. Verify that the iSCSI exported volumes have been discovered.
# cat /proc/scsi/scsi

3. Check the block device file created in the system.
