4.1.2 FC Host Port Loop IDs
If the topology is set to loop, you can set up the FC loop ID for each SM’s
host ports. You may need to change the FC loop ID if you want the SM
to be at a specific address or if your system checks addresses in reverse
order (lowest address first). You must restart both SMs after changing
the loop ID.
To set up the host port loop IDs:
1. In SAM, select
Manage EF2800
>
General Config
>
Host Port
Configuration
. The Host Port Configuration page displays .
2. In the Advanced Options panel, click the blue Change FC Loop ID
text.
A second Host Port Configuration page displays. If the Requested
Loop ID drop-down list is different from the Current ID, your
requested change has not yet been processed. Complete the steps
below to make the change.
3. For each SM, select the loop ID you want.
- SOFT: Use this setting if you do not care whether the EF2800’s
Loop ID changes when you power down and power up. This
setting lets the FC loop initialization process determine the
Loop ID.
- Any number between 0 and 125: Select a specific number if you
want the Loop ID to stay the same after you power down and
power up. SAM cannot tell you which loop IDs are available. To
be sure that you have successfully assigned the loop ID you
want, check the loop ID here or from
Monitor EF2800
>
FC Port
Status
after you restart the SM. If the SM cannot get the
specified Loop ID during the loop initialization process, it will
try to get a soft address.
4. Click
Save and Continue
to save your changes and return to the
first Host Port Configuration page.
5. Restart both SM by selecting
Manage EF2800
>
Manage Modules
>
Shutdown/Restart
. (for more information, see 4.3.1 on page 62 ).
