Configuring SRP
Configuring ITLs with Element Manager while Global Policy Restrictions Apply
This section describes how to configure ITLs with Element Manager while global policy restrictions
apply. These instructions apply to environments where the portmask policy and LUN masking policy are
both restricted. To verify that you have restricted your policies, enter the show fc srp-global command
at the CLI prompt. View the default-gateway-portmask-policy and default-lun-policy fields. If
restrictions apply to either field, restricted appears in the field output.
To configure ITLs with a Linux SRP host while your port masking and LUN masking policies are
restricted, perform the following steps:
Step 1
Log in to your host.
Step 2
Display the host GUID by entering the hca_self_test | grep -i guid command at the host CLI.
Note
Bring up the Fibre Channel gateways on your server switch with the following steps:

Note
Step 4
From the Fibre Channel menu, select Storage Manager.
Step 5
Click the SRP Hosts folder in the Storage navigation tree in the left-hand frame of the interface. The
SRP Hosts display appears in the right-hand frame of the interface.
Step 6
Click Define New in the SRP Hosts display. The Define New SRP Host window opens.
Note
Step 7
Select a GUID from the Host GUID drop-down menu in the Define New SRP Host window. The menu
displays the GUIDs of all available hosts that you have not yet configured as initiators.
Step 8
(Optional) Type a description in the Description field in the Define New SRP Host window. If you do
not enter a description, your device will assign a description.

Record the GUID value. You are required later to enter it repeatedly.
Launch Element Manager.
Double-click the Fibre Channel gateway card that you want to bring up. The Fibre Channel Card
window opens.
Click the Up radio button in the Enable/Disable Card field, and then click Apply.
(Optional) Repeat this process for additional gateways.
The Fibre Channel gateway automatically discovers all attached storage.
Discovered LUs remain gray (inactive) until an SRP host connects to them. Once a host connects
to an LU, its icon becomes blue (active).
If your host includes multiple HCAs, you must configure each individual HCA as an initiator.
When you configure one HCA in a host, other HCAs in the host are not automatically
configured.
