44 Post Installation Tasks
5
Configure the IP protocols and addresses for the iSCSI ports.
6
Specify the CHAP authentication method.
7
Apply the settings after reviewing a summary.
8
Repeat the process starting from step 2 to configure additional arrays.
Host Configuration (Host Connectivity Configuration)
After you have completed configuring your iSCSI-based storage arrays, the
next task is to run this utility on all hosts that need to access the storage
arrays. Depending on your network configuration, your host may be the same
machine you use to manage your storage arrays, or it may be on a completely
separate network.
The option to configure a host is disabled if the machine the utility is running
on does not have an iSCSI initiator or the required driver components
installed. When the option is disabled, the utility also displays an
informational message. If you are running the utility on a host which is not
connected to the iSCSI–based storage array (or which you do not wish to
connect to the array), the informational message can be ignored.
The task generally involves the following steps:
1
Discover available storage array(s) for connection.
2
Select a storage array to connect to.
3
Specify the CHAP secret.
4
Select the iSCSI ports the host's initiator uses to log on.
5
Repeat the process starting from step 2 to connect to additional arrays.
6
Repeat these steps on each host that needs access to the storage array(s).
Before Starting the Configuration Process
Keep the following guidelines in mind for the storage array and host
configuration:
• For optimal performance, ensure your network configuration is valid by
consulting the storage array's support matrix.
• If your host has multiple network interfaces, it is recommended that each
network interface uses a separate subnet.
