4) Acquire the iSCSI initiator name for your SLES server:

# cat /etc/iscsi/initiatorname.iscsi

InitiatorName=iqn.1994-05.com.default:6891f663d4ce

5) At this point, the two Ethernet interfaces should be accessible to the iSCSI initiator

software running on the SLES server. In order to utilize both connection paths, the

iSCSI volume must have appropriate iSCSI Access settings. Use the PS Group

Manager to create a new volume with these settings:

 Volume name = mpio

 Size of 50G

 Access set to ’iscsi initiator’ (use name from above ‘cat’ command)

6) Discover the new volume from the SLES server:

# iscsiadm –m discovery –t sendtargets –p 10.10.5.7

10.10.5.7:3260,1 iqn.2001-05.com.equallogic:0-8a0906-faae66602-

9316e11da434c126-mpio

10.10.5.7:3260,1 iqn.2001-05.com.equallogic:0-8a0906-faae66602-

9316e11da434c126-mpio

Note: two iscsiadm records are listed for the ‘mpio’ volume. This is because there

are two Ethernet interface records in the iscsiadm DB.

7) Login to the newly discovered volume:

# iscsiadm -m node -T <iqn> -p 10.10.5.7 --login

Logging in to [iface: eth2, target: iqn.2001-

05.com.equallogic:0-8a0906-faae66602-9316e11da434c126-mpio,

portal: 10.10.5.7,3260]

Logging in to [iface: eth3, target: iqn.2001-

05.com.equallogic:0-8a0906-faae66602-9316e11da434c126-mpio,

portal: 10.10.5.7,3260]

8a0906-faae66602-9316e11da434c126-mpio, portal:

10.10.5.7,3260]: successful

8a0906-faae66602-9316e11da434c126-mpio, portal:

10.10.5.7,3260]: successful

Note: that both logins succeeded, one on ‘eth2’ and the other on ‘eth3’.

Completion of this step verifies that the multiple connection paths between the

SLES server and the PS Storage array are active.
