244 Administering FICON fabrics
• Some 1-Gbit/sec storage devices cannot auto-negotiate speed with the 4/256 SAN Director or SAN
Switch 4/32 ports. For these types of devices, configure ports that are connected to 1-Gbit/sec storage
devices for fixed 1-Gbit/sec speed.
Preparing a switch
To verify and prepare a switch for use in a FICON environment, complete the following steps:
1. Connect to the switch and log in as admin.
2. If not in a cascaded environment, proceed to step 3 .
If in a FICON cascaded environment, enter the following commands:
•
licenseShow
to verify that required licenses (Secure Fabric OS and Zoning) are activated
•
secModeShow
to determine if Secure Fabric OS is enabled; if it is disabled, enable it
•
secPolicyShow
to verify that the SCC_POLICY is active
•
pkiShow
to determine the existence of PKI objects, such as switch private key, private key
passphrase, CSR, root certificate, and switch certificate. If none of these objects exists, refer to the
Secure Fabric OS Administrator’s Guide for information about creating the PKI objects and
obtaining the digital certificate file.
3. Enter the
switchShow
command to verify that the switch and devices are online.
4. Change the routing policy on the switch from the default exchange-based policy to the required
port-based policy for those switches with FICON devices directly attached. For the SAN Switch 4/32,
refer to the Fabric OS Command Reference Manual for details about the
aptPolicy
command. For
the 4/256 SAN Director, refer to the Web Tools Administrator’s Guide .
5. Enter the
ficonshow rnid
command to verify that the FICON devices are registered with the switch.
6. Enter the
ficonshow lirr
command to verify that the FICON host channels are registered to listen
for link incidents.
7. Optionally, refer to ” Using FICON CUP ” on page 248 for details about using FICON CUP.
Configuring a single switch
Single-switch configuration does not require IDID or fabric binding, provided that connected channels are
configured for single-byte addressing. However, you should configure IDID to ensure that domain IDs are
maintained.
Configuring a high-integrity fabric
To configure a high-integrity fabric (cascaded configuration):
1. Disable each switch in the fabric.
2. For each switch:
a. Enable the IDID flag.
b. Set the domain ID.
c. Install security certificates and keys.
3. Enable the switches; this builds the fabric.
4. Set up security on the primary FCS switch.
Use the
secModeEnable
command. The security policies are distributed to each switch in the fabric.
(For details on the Quickmode procedure, refer to the Secure Fabric OS Administrator’s Guide .
