Configuring a Brocade FC switch after site disaster

You must use this Brocade-specific procedure to configure the replacement switch and enable the ISL ports.

About this task

The examples in this procedure are based on the following assumptions:
  • Site A is the disaster site.
  • FC_switch_A_1 has been replaced.
  • FC_switch_A_2 has been replaced.
  • Site B is the surviving site.
  • FC_switch_B_1 is healthy.
  • FC_switch_B_2 is healthy.
You must verify that you are using the specified port assignments when you cable the FC switches:

The examples show two FC-to-SAS bridges. If you have more bridges, you must disable and subsequently enable the additional ports.


  1. Boot and pre-configure the new switch:
    1. Power up the new switch and let it boot up.
    2. Check the firmware version on the switch to confirm it matches the version of the other FC switches: firmwareShow
    3. Configure the new switch as described in the MetroCluster Installation and Configuration Guide, skipping the steps for configuring zoning on the switch.
    4. Disable the switch persistently: switchcfgpersistentdisable
      The switch will remain disabled after a reboot or fastboot. If this command is not available, you should use the switchdisable command.
      The following example shows the command on BrocadeSwitchA:
      BrocadeSwitchA:admin> switchcfgpersistentdisable
      The following example shows the command on BrocadeSwitchB:
      BrocadeSwitchA:admin> switchcfgpersistentdisable
  2. Complete configuration of the new switch:
    1. Enable the ISLs on the surviving site: portcfgpersistentenable port-number
      FC_switch_B_1:admin> portcfgpersistentenable 10
      FC_switch_B_1:admin> portcfgpersistentenable 11
    2. Enable the ISLs on the replacement switches: portcfgpersistentenable port-number
      FC_switch_A_1:admin> portcfgpersistentenable 10
      FC_switch_A_1:admin> portcfgpersistentenable 11
    3. On the replacement switch (FC_switch_A_1 in our example) verify that the ISL's are online:switchshow
      FC_switch_A_1:admin> switchshow
      switchName: FC_switch_A_1
      switchType: 71.2
      switchMode: Native
      switchRole: Principal
      switchDomain:       4
      switchId:   fffc03
      switchWwn:  10:00:00:05:33:8c:2e:9a
      zoning:             OFF
      switchBeacon:       OFF

  3. Persistently enable the switch: switchcfgpersistentenable
  4. Verify that the ports are online:switchshow
