38 Post Installation Tasks
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.
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
Before you start configuring the storage array or host connectivity, it is
recommended that you fill out the iSCSI configuration worksheet to help you
plan your configuration. You may need to use several worksheets depending
on your configuration.
Keep the following guidelines in mind for the storage array and host
configuration:
• For optimal performance, ensure your network configuration.See the
storage array's
Support Matrix
at dell.com/support/manuals.
• If your host has multiple network interfaces, it is recommended that each
network interface uses a separate subnet.
• For redundancy in a dual controller (duplex) configuration, ensure each
host network interface is configured to connect to both storage array
controllers.
• For optimal load balancing, ensure each host network interface that is used
for iSCSI traffic is configured to connect to each storage array controller.
• It is recommended that each host network interface only establishes one
iSCSI session per storage array controller.
NOTE: The utility tries to follow the guidelines for the host connectivity whenever
possible based on the available host network interfaces and their connectivity with
the iSCSI host ports of the storage array.
