Table 4-4: Add SCSI Devices

Purpose

Command

Add a device (for

FC-SAN
environments)

When using a QLogic HBA driver on Red Hat Enterprise Linux AS4/ES4 Update 1,

execute the commands in the following order:

# echo "scsi-qlascan" > /proc/scsi/

driver-name

/

n

# cat /proc/scsi/

driver-name

/

n

View the

Id:Lun

part, which is output under

SCSI

LUN

Information:

, of the output

command result, and then execute the following command based on the target ID of

the added device:

# echo "scsi add-single-device

a b c d

" > /proc/scsi/scsi

When using an Emulex HBA driver on Red Hat Enterprise Linux AS4/ES4 Update 1,

execute the following command:

# echo "scsi add-single-device a b c d" > /proc/scsi/scsi

When using any of the following OS and HBA driver combinations:

- Red Hat Enterprise Linux AS4/ES4 Update 3 or later and a QLogic HBA driver
- Red Hat Enterprise Linux 5 or Red Hat Enterprise Linux 6 and a QLogic HBA driver
- SUSE LINUX Enterprise Server and a QLogic HBA driver
- Red Hat Enterprise Linux AS4/ES4 Update 3 or later and an Emulex HBA driver
- Red Hat Enterprise Linux 5 or Red Hat Enterprise Linux 6 and an Emulex HBA
driver
- SUSE LINUX Enterprise Server and an Emulex HBA driver
- Red Hat Enterprise Linux 5 or Red Hat Enterprise Linux 6 and a Brocade HBA driver
- SUSE LINUX Enterprise Server and a Brocade HBA driver
Execute the following command:

# echo "- - -" > /sys/class/scsi_host/host

n

/scan

Execute the following command to check whether the OS has recognized any devices:

# cat /proc/scsi/scsi

If the OS has not recognized any devices, execute the following commands in the order

shown:

# echo "1" > /sys/class/fc_host/hostn/issue_lip

# echo "- - -" > /sys/class/scsi_host/host

n

/scan

If you are using Red Hat Enterprise Linux 5, Red Hat Enterprise Linux 6, SUSE
LINUX Enterprise Server 10, or SUSE LINUX Enterprise Server 11, the devices might

be automatically recognized by the OS hot plug function. If the devices are recognized,

the above procedure is not necessary.

Adding a device

(for IP-SAN

environments)

For a device added to the target for which no session is established with the iSCSI

initiator
Execute the following command to make the OS recognize the target:

# iscsiadm -m discovery -t sendtargets -p

IP-address-of-the-target

Then, log in to the target to establish a session.

# iscsiadm -m node -T

target-name

-p

IP-address-of-the-target

:

port-number-of-the-target

--login

For a device added to the target for which a session is established with the iSCSI

initiator
Execute the following command:

# iscsiadm -m session -R
