Configuring SRP
This section contains information on how to configure your IB fabric to connect an SRP host to a SAN
and includes the following topics:
• Configuring ITLs when Using Fibre Channel Gateway, page 4-2
• Configuring SRP Host, page 4-6
Note If you intend to manage your environment with Cisco VFrame software, do not configure ITLs.
Configuring ITLs when Using Fibre Channel Gateway
This section describes how to configure ITLs when using Fibre Channel gateway. When you configure
initiators, you assign Fibre Channel WWNNs to SRP hosts so that the SAN can recognize the hosts.
Steps to configure initiators are provided in this section.
To configure initiators that you have not yet connected to your fabric, enter the GUID of the initiator into
the CLI or Element Manager so that the configuration works when you connect the SRP host.
You must configure ITLs for your initiators to communicate with your storage. You can configure ITLs
with the CLI or the Element Manager GUI.
• If you restricted port and LUN access when you configured global attributes, proceed to the
“Configuring ITLs with Element Manager while Global Policy Restrictions Apply” section on
page 4-4.
• If you have not configured access, perform the steps as appropriate in “Configuring ITLs with
Element Manager while No Global Policy Restrictions Apply” section on page 4-2 or in
“Configuring ITLs with Element Manager while Global Policy Restrictions Apply” section on
page 4-4.
Note If you enter a Fibre Channel command and receive an error message that reads Operation temporarily
failed - try again
, give your Fibre Channel gateway time to finish initializing, and then retry the
command.
Configuring ITLs with Element Manager while No Global Policy Restrictions Apply
This section describes how to configure ITLs with Element Manager while no global policy restrictions
apply. To configure ITLs with a Linux SRP host while your port masking and LUN masking policies are
unrestricted, 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.
Note Record the GUID value (always similar format 00:00:00:00:00:00:00:00). You are required later
to enter it repeatedly.
