50 iSCSI Cluster Setup for EqualLogic Storage Systems
# iscsiadm -m iface -I eth0-iface --op=update -n
iface.hwaddress -v 00:18:8B:4E:E6:CC
eth0-iface updated
6 Verify that the interfaces are created and associated properly:
iscsiadm -m iface
7 Modify the CHAP information in /etc/iscsi/iscsid.conf on the host.
node.session.auth.authmethod = CHAP
node.session.auth.username = username
node.session.auth.password = password
discovery.sendtargets.auth.authmethod = CHAP
discovery.sendtargets.auth.username = username
discovery.sendtargets.auth.password = password
where, username is the CHAP username defined in the EqualLogic
storage, and
password is the CHAP password defined in the EqualLogic
storage.
8 Modify the replacement timeout value located in the /etc/iscsi/iscsid.conf
file from 120 to 30:
node.session.timeo.replacement_timeout = 30
9 Restart the iSCSI service for the new configuration to take effect.
service iscsi stop
service iscsi start
10 Discover the targets from all ifaces created in step 5.
iscsiadm -m discovery -t st -p group_ip_address --
interface=iface_name1 --interface=iface_name2 --
interface=iface_name3 --interface=iface_name4
,
where, group_ip_address is the IP address of the EqualLogic storage
group,
iface_name1 , iface_name2 , iface_name3 , iface_name4 , etc, are the
network interfaces (as defined in
step 5) on the host that is used for iSCSI
traffic.
For example, the following command discovers four volumes at group
IP
address 10.16.7.100 , from a host with two interfaces named as
eth0-iface and eth1-iface :
# iscsiadm -m discovery -t st -p 10.16.7.100 --
interface=eth0-iface --interface=eth1-iface
10.16.7.100:3260,1 iqn.2001-05.com.equallogic:0-
