Using Windows Server 2008 Core Version

1) Set the iSCSI initiator service to start automatically:

\\<server_name> config msiscsi

start= auto

2)

Start the iSCSI service:

start msiscsi

3) Add a target portal:

iscsicli QAddTargetPortal

<IP_address_of_iSCSI_port_on_storagearray>

Using Linux Server

Configuration of the iSCSI initiator for Red Hat

®

Enterprise Linux

®

version 4 and SUSE

®

Linux Enterprise

Server 9 distributions is performed by modifying the /etc/iscsi.conf file, which is installed by default when
you installed the iSCSI initiator. The /etc/iscsi.conf file needs to be changed before using the initiator:

1) Edit the /etc/iscsi.conf file and replace the IP address entries shown for

DiscoveryAddress=

with the IP addresses assigned to the iSCSI ports on your iSCSI to SAS bridge:

2) Edit (or add) the following entries to the /etc/iscsi.conf file:

HeaderDigest=never
DataDigest=never
LoginTimeout=15
IdleTimeout=15
PingTimeout=5
ConnFailTimeout=144
AbortTimeout=10
ResetTimeout=30
Continuous=no
InitialR2T=no
ImmediateData=yes
MaxRecvDataSegmentLength=65536
FirstBurstLength=262144
MaxBurstLength=16776192

3) Restart the iSCSI daemon by executing the following command from the console:

/etc/init.d/iscsi restart

4) Verify that the server can connect to the iSCSI to SAS bridge by executing this command from a

console:

iscsi –ls.

If successful, an iSCSI session has been established to each iSCSI port

on the iSCSI to SAS bridge.

Using RHEL 5 or SLES 10 SP1

Configuration of the iSCSI initiator for RHEL version 5 and SLES 10 SP1 distributions is done by
modifying the /etc/iscsi/iscsid.conf file.

1) Edit the following entries in the /etc/iscsi/iscsid.conf file:

a) Edit (or verify) that the

node.startup = manual

line is disabled.

b) Edit (or verify) that the

node.startup = automatic

line is enabled. This will enable

automatic startup of the service at boot time.

c) Verify that the following time-out value is set to 144:

node.session.timeo.replacement_timeout = 144

d) Save and close the /etc/iscsi/iscsid.conf file.

2) From the console, restart the iSCSI service with the following command:

service iscsi

start

3) Verify that the iSCSI service is running during boot using the following command from the

console:

chkconfig iscsi on

4) To display the available iscsi targets at the specified IP address, use the following command:

iscsiadm –m discovery –t st -p <IP_address_of_iSCSI_port>

5) After target discovery, use the following command to manually login:

iscsiadm -m node –l.

This logon will be performed automatically at startup if automatic startup is enabled.

6) Manually log out of the session using the following command:

iscsiadm -m node -T

<initiator_username> -p <target_ip> -u
