Configure the iSCSI initiators to connect to the ME4 Series storage system
For RHEL 7
1. From the server terminal or console, run the following iscsiadm command to discover targets (port A0):
iscsiadm –m discovery –t sendtargets –p <IP>
Where <IP> is the IP address. For example:
iscsiadm –m discovery –t sendtargets –p 172.1.100.128
2. With the discovery output, log in to each portal by running the iscsiadm command:
a) Run iscsiadm –m node –T <full IQN > -p <IP>
Where <full IQN> is the full IQN listing from the output in step 1 and <IP> is the IP address. For example:
iscsiadm –m node –T iqn.1988-11.com.abcc:01.array.bc305bb0b841-p 172.1.100.128
b) Repeat the login for each controller host port using the discovery command output in step 1.
c) Reboot the host to ensure that all targets are automatically connected.
For SLES 12
1. From the server terminal or console, use the yast command to access YaST Control Center.
2. Select Network Service > iSCSI Initiator.
