Connecting the SAN I/O Module to the Ethernet network 2
Connecting the SAN I/O Module to the Ethernet network
Once you have successfully set the appropriate IP address of the SAN I/O Module, you can
establish an Ethernet connection through the Chassis Management Controller (CMC) to a remote
management workstation for any additional configuration. The management workstation must be
on the same Ethernet subnet as the CMC.
NOTE
Ensure that the SAN I/O Module is not being modified from any other connection until configuration
is complete.
Connecting the SAN I/O Module to the fabric
NOTE
Refer to “Cabling guidelines” on page 8 before beginning the following procedure.
Before beginni ng the followi ng steps, dete rmine whether the SAN I/O Module is in Access Gateway
or Full Fabric Switch mode. This affects the configuration process. Using the SAN I/O Module CLI,
you can enter the ag ––modeShow command to determine the current operating mode.
1. If the SAN I/O Module is in Full Fabric Switch mode, continue with step2 and step 3. If the
Module is in Access Gateway Mode, go on to step4.
2. Log onto the SAN I/O Module through a Telnet connection, using the admin account.
3. Modify the domain ID if required using SAN I/O Module CLI commands.
The default domain ID is 1. If the SAN I/O Module is not powered on until after it is connected
to the fabric and the default domain ID is already in use, the domain ID for the new SAN I/O
Module is automatically reset to a unique value. If the SAN I/O Module is connected to the
fabric after it has been powered on and the default domain ID is already in use, the fabric
segments.
To find the domain IDs that are currently in use, run the fabricShow command on another SAN
I/O Module in the fabric. Identify an unused domain ID:
a. Disable the SAN I/O Module being configured using the switchDisable command.
b. Enter the configure command.
The command prompts display sequentially. Enter a new value or press Enter to accept
each default value. The SAN I/O Module now has a unique domain ID and can join the
fabric. Following is an example of command output.
