474 Configuring and monitoring FCIP extension services
Example: Disabling FC Fastwrite on a switch
switch:admin> fastwritecfg --disable 7
!!!! WARNING !!!!
Disabling FC Fastwrite will require powering off and back on the and it may take
up to 5 minutes. For non bladed system, the switch will be rebooted. Data traffic
will be disrupted.
Continue (Y,y,N,n): [ n] y
Slot 7 is being powered off
Disabling FC Fastwrite on a port
1. Connect to the switch and log in using an account assigned to the admin role.
2. Enter the following command:
switch:admin> portcfg fastwrite [slot/]port --disable
where
slot
is the slot in which the B-Series Multi-Protocol Router Blade is installed, and port is the port
number. A slot number is not required for the BHP StorageWorks 400 Multi-Protocol Router.
FCIP services configuration guidelines
There are multiple configuration requirements and options associated with FCIP services. The following
general guidelines may be helpful. The steps are presented in an order that minimizes the number of times
ports need to be disabled and enabled. In practice, the steps do not have to be taken in this order.
1. Determine if you are implementing IPsec.
IPsec configuration may be done at any time, but defining IPsec policies first ensures that they will be
available when FCIP tunnels are configured. See ” IPsec configuration ” on page 461 for specific
instructions.
2. Determine which FCIP tunnel you want to configure.
Each FCIP tunnel is associated with a specific virtual port, and a specific Ethernet port, as shown in
Table 90 on page 457. For example, if you want to configure FCIP tunnel 0, you need to configure
virtual port 16, and define an IP interface and one or more IP routes over ge0.
3. Persistently disable the virtual ports before you configure them.
Ports on a new HP StorageWorks 400 Multi-Protocol Router or B-Series Multi-Protocol Router Blade are
persistently disabled by default. On an HP StorageWorks 400 Multi-Protocol Router or FC4-18i blade
that has already been installed and configured, check the EX_Port status using the
portCfgShow
command, and persistently disable the ports using the
portCfgPersistentDisable
command
before you configure them. See ” Setting persistently disabled ports ” on page 475 for a description.
4. The Ethernet port associated with the tunnel should also be disabled. Before disabling an Ethernet port,
be sure there are no other tunnels active on the port. If there are, disabling the port will disable the
tunnel or tunnels.
5. Determine if any of the virtual ports should be VEX_Ports, and configure them using the
portCfgVEXPort
command. See ” Configuring VEX_Ports ” on page 475 for specific instructions.
6. Create an IP interface using the
portCfg ipif
command. See ” Creating IP interfaces and routes ” on
page 476 for specific instructions.
7. Create one or more IP routes using the
portCfg iproute
command. See ” Creating IP interfaces and
routes ” on page 476 for specific instructions.
8. If you are implementing VLAN tagging, create a static ARP entry for the IP interface using the
portCfg
arp
command. See ” Creating IP interfaces and routes ” on page 476 for specific instructions.
9. Test the IP connection using the
portCmd
--
ping
command. See ” Creating IP interfaces and routes ”
on page 476 for specific instructions.
10. Create an FCIP tunnel using the
portCfg fciptunnel
command. See ” Creating an FCIP tunnel ” on
page 478 for specific instructions.
