CAUTION

The Linux iSCSI driver gives the same name to all NICs in a server. This name identifies the server, not the individual NICs, to a storage-system SP. This means that if multiple NICs from the same server are connected to an SP only one NIC is actually used. Other NICs are in standby mode. The server will use one of the others if the first NIC fails.

STEP 1. For an existing storage system with initiator CHAP already configured, stop the iSCSI service:

/etc/init.d/iscsi stop

STEP 2. Define a discovery address and other parameters in the iSCSI driver configuration file:

a.Open the /etc/iscsi.conf file on your server with vi or another editor.

b.Under Discovery Address Category, after the line

#DiscoveryAddress=10.4.100.0,

add a new, uncommented DiscoveryAddress= SP_port_ip_address line for each 1-Gbit iSCSI data port on each storage-system SP to which the NICs in that server have access. For SP_port_ip_address, use the data port addresses from section B on the Administration Worksheet (see Procedure 3, "Planning Your iSCSI Storage System Configuration," on page 15) that you completed. For example,

#DiscoveryAddress=10.4.100.0

DiscoveryAddress=172.31.1.100

DiscoveryAddress=172.31.2.100 Under Digest Settings , uncomment HeaderDigest=never DataDigest=never

Under PORTAL FAILOVER SETTINGS, uncomment PortalFailover=no

Under MULTIPATH SETTINGS, uncomment Multipath=yes

Under LUN SETTINGS, uncomment LUNs=0-255

Under SESSION TIMEOUT SETTINGS, uncomment the following parameter and change <number> to 10: DiskCommandTimout=10

Under CONTINUOUS DISCOVERY SETTINGS, uncomment Continuous=yes

Under iSCSI OPERATIONAL PARAMETER SETTINGS, uncomment InitialR2T=yes

ImmediateData=yes

Any other changes to the non-CHAP part of the configuration file are not supported.

STEP 3. After you edit the configuration file, start the iSCSI service:

/etc/init.d/iscsi start
