Configuring a Cisco FC switch after site disaster

You must use the Cisco-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.

  1. Configure the switch:
    1. Download the Fabric-attached MetroCluster Installation and Configuration Guide.

      Fabric-attached MetroCluster installation and configuration

    2. Follow the steps for configuring the switch in the Configuring the Cisco FC switches section, except for the Configuring zoning on a Cisco FC switch section.

    Zoning is configured later in this procedure.

  2. On the healthy switch (in this example, FC_switch_B_1), enable the ISL ports.

    Example

    The following example shows the commands to enable the ports:

    FC_switch_B_1# conf t
    FC_switch_B_1(config)# int fc1/14-15
    FC_switch_B_1(config)# no shut
    FC_switch_B_1(config)# end
    FC_switch_B_1# copy running-config startup-config
    FC_switch_B_1#
  3. Verify that the ISL ports are up by using the show interface brief command.
  4. Retrieve the zoning information from the fabric.

    Example

    The following example shows the commands to distribute the zoning configuration:

    FC_switch_B_1(config-zone)# zoneset distribute full vsan 10
    FC_switch_B_1(config-zone)# zoneset distribute full vsan 20
    FC_switch_B_1(config-zone)# end
    FC_switch_B_1 is distributed to all other switches in the fabric for vsan 10 and vsan 20, and the zoning information is retrieved from FC_switch_A_1.
  5. On the healthy switch, verify that the zoning information is properly retrieved from the partner switch: show zone

    Example

    FC_switch_B_1# show zone
    zone name FC-VI_Zone_1_10 vsan 10
      interface fc1/1 swwn 20:00:54:7f:ee:e3:86:50
      interface fc1/2 swwn 20:00:54:7f:ee:e3:86:50
      interface fc1/1 swwn 20:00:54:7f:ee:b8:24:c0
      interface fc1/2 swwn 20:00:54:7f:ee:b8:24:c0

    zone name STOR_Zone_1_20_25A vsan 20
      interface fc1/5 swwn 20:00:54:7f:ee:e3:86:50
      interface fc1/8 swwn 20:00:54:7f:ee:e3:86:50
      interface fc1/9 swwn 20:00:54:7f:ee:e3:86:50
      interface fc1/10 swwn 20:00:54:7f:ee:e3:86:50
      interface fc1/11 swwn 20:00:54:7f:ee:e3:86:50
      interface fc1/8 swwn 20:00:54:7f:ee:b8:24:c0
      interface fc1/9 swwn 20:00:54:7f:ee:b8:24:c0
      interface fc1/10 swwn 20:00:54:7f:ee:b8:24:c0
      interface fc1/11 swwn 20:00:54:7f:ee:b8:24:c0

    zone name STOR_Zone_1_20_25B vsan 20
      interface fc1/8 swwn 20:00:54:7f:ee:e3:86:50
      interface fc1/9 swwn 20:00:54:7f:ee:e3:86:50
      interface fc1/10 swwn 20:00:54:7f:ee:e3:86:50
      interface fc1/11 swwn 20:00:54:7f:ee:e3:86:50
      interface fc1/5 swwn 20:00:54:7f:ee:b8:24:c0
      interface fc1/8 swwn 20:00:54:7f:ee:b8:24:c0
      interface fc1/9 swwn 20:00:54:7f:ee:b8:24:c0
      interface fc1/10 swwn 20:00:54:7f:ee:b8:24:c0
      interface fc1/11 swwn 20:00:54:7f:ee:b8:24:c0
    FC_switch_B_1#
  6. Determine the worldwide names (WWNs) of the switches in the switch fabric.

    Example

    In this example, the two switch WWNs are as follows:

    • FC_switch_A_1: 20:00:54:7f:ee:b8:24:c0

    • FC_switch_B_1: 20:00:54:7f:ee:c6:80:78

    FC_switch_B_1# show wwn switch
    Switch WWN is 20:00:54:7f:ee:c6:80:78
    FC_switch_B_1#
            
    FC_switch_A_1# show wwn switch
    Switch WWN is 20:00:54:7f:ee:b8:24:c0
    FC_switch_A_1#
  7. Enter configuration mode for the zone and remove zone members that do not belong to the switch WWNs of the two switches: no member interface interface-ide swwn wwn

    Example

    In this example, the following members are not associated with the WWN of either of the switches in the fabric and must be removed:

    • Zone name FC-VI_Zone_1_10 vsan 10

      • Interface fc1/1 swwn 20:00:54:7f:ee:e3:86:50

      • Interface fc1/2 swwn 20:00:54:7f:ee:e3:86:50

    • Zone name STOR_Zone_1_20_25A vsan 20

      • Interface fc1/5 swwn 20:00:54:7f:ee:e3:86:50

      • Interface fc1/8 swwn 20:00:54:7f:ee:e3:86:50

      • Interface fc1/9 swwn 20:00:54:7f:ee:e3:86:50

      • Interface fc1/10 swwn 20:00:54:7f:ee:e3:86:50

      • Interface fc1/11 swwn 20:00:54:7f:ee:e3:86:50

    • Zone name STOR_Zone_1_20_25B vsan 20

      • Interface fc1/8 swwn 20:00:54:7f:ee:e3:86:50

      • Interface fc1/9 swwn 20:00:54:7f:ee:e3:86:50

      • Interface fc1/10 swwn 20:00:54:7f:ee:e3:86:50

      • Interface fc1/11 swwn 20:00:54:7f:ee:e3:86:50

    The following example shows the removal of these interfaces:

     FC_switch_B_1# conf t
     FC_switch_B_1(config)# zone name FC-VI_Zone_1_10 vsan 10
     FC_switch_B_1(config-zone)# no member interface fc1/1 swwn 20:00:54:7f:ee:e3:86:50
     FC_switch_B_1(config-zone)# no member interface fc1/2 swwn 20:00:54:7f:ee:e3:86:50
     FC_switch_B_1(config-zone)# zone name STOR_Zone_1_20_25A vsan 20
     FC_switch_B_1(config-zone)# no member interface fc1/5 swwn 20:00:54:7f:ee:e3:86:50
     FC_switch_B_1(config-zone)# no member interface fc1/8 swwn 20:00:54:7f:ee:e3:86:50
     FC_switch_B_1(config-zone)# no member interface fc1/9 swwn 20:00:54:7f:ee:e3:86:50
     FC_switch_B_1(config-zone)# no member interface fc1/10 swwn 20:00:54:7f:ee:e3:86:50
     FC_switch_B_1(config-zone)# no member interface fc1/11 swwn 20:00:54:7f:ee:e3:86:50
     FC_switch_B_1(config-zone)# zone name STOR_Zone_1_20_25B vsan 20
     FC_switch_B_1(config-zone)# no member interface fc1/8 swwn 20:00:54:7f:ee:e3:86:50
     FC_switch_B_1(config-zone)# no member interface fc1/9 swwn 20:00:54:7f:ee:e3:86:50
     FC_switch_B_1(config-zone)# no member interface fc1/10 swwn 20:00:54:7f:ee:e3:86:50
     FC_switch_B_1(config-zone)# no member interface fc1/11 swwn 20:00:54:7f:ee:e3:86:50
     FC_switch_B_1(config-zone)# save running-config startup-config
     FC_switch_B_1(config-zone)# zoneset distribute full 10
     FC_switch_B_1(config-zone)# zoneset distribute full 20
     FC_switch_B_1(config-zone)# end
     FC_switch_B_1# copy running-config startup-config

  8. Add the ports of the new switch to the zones.

    Example

    The following example assumes that the cabling on the replacement switch is the same as on the old switch:

     FC_switch_B_1# conf t
     FC_switch_B_1(config)# zone name FC-VI_Zone_1_10 vsan 10
     FC_switch_B_1(config-zone)# member interface fc1/1 swwn 20:00:54:7f:ee:c6:80:78
     FC_switch_B_1(config-zone)# member interface fc1/2 swwn 20:00:54:7f:ee:c6:80:78
     FC_switch_B_1(config-zone)# zone name STOR_Zone_1_20_25A vsan 20
     FC_switch_B_1(config-zone)# member interface fc1/5 swwn 20:00:54:7f:ee:c6:80:78
     FC_switch_B_1(config-zone)# member interface fc1/8 swwn 20:00:54:7f:ee:c6:80:78
     FC_switch_B_1(config-zone)# member interface fc1/9 swwn 20:00:54:7f:ee:c6:80:78
     FC_switch_B_1(config-zone)# member interface fc1/10 swwn 20:00:54:7f:ee:c6:80:78
     FC_switch_B_1(config-zone)# member interface fc1/11 swwn 20:00:54:7f:ee:c6:80:78
     FC_switch_B_1(config-zone)# zone name STOR_Zone_1_20_25B vsan 20
     FC_switch_B_1(config-zone)# member interface fc1/8 swwn 20:00:54:7f:ee:c6:80:78
     FC_switch_B_1(config-zone)# member interface fc1/9 swwn 20:00:54:7f:ee:c6:80:78
     FC_switch_B_1(config-zone)# member interface fc1/10 swwn 20:00:54:7f:ee:c6:80:78
     FC_switch_B_1(config-zone)# member interface fc1/11 swwn 20:00:54:7f:ee:c6:80:78
     FC_switch_B_1(config-zone)# save running-config startup-config
     FC_switch_B_1(config-zone)# zoneset distribute full 10
     FC_switch_B_1(config-zone)# zoneset distribute full 20
     FC_switch_B_1(config-zone)# end
     FC_switch_B_1# copy running-config startup-config
  9. Verify that the zoning is properly configured: show zone

    Example

    The following example output shows the three zones:

     FC_switch_B_1# show zone
       zone name FC-VI_Zone_1_10 vsan 10
         interface fc1/1 swwn 20:00:54:7f:ee:c6:80:78
         interface fc1/2 swwn 20:00:54:7f:ee:c6:80:78
         interface fc1/1 swwn 20:00:54:7f:ee:b8:24:c0
         interface fc1/2 swwn 20:00:54:7f:ee:b8:24:c0
     
       zone name STOR_Zone_1_20_25A vsan 20
         interface fc1/5 swwn 20:00:54:7f:ee:c6:80:78

         interface fc1/8 swwn 20:00:54:7f:ee:b8:24:c0
         interface fc1/9 swwn 20:00:54:7f:ee:b8:24:c0
         interface fc1/10 swwn 20:00:54:7f:ee:b8:24:c0
         interface fc1/11 swwn 20:00:54:7f:ee:b8:24:c0

       zone name STOR_Zone_1_20_25B vsan 20
         interface fc1/8 swwn 20:00:54:7f:ee:c6:80:78
         interface fc1/9 swwn 20:00:54:7f:ee:c6:80:78

         interface fc1/8 swwn 20:00:54:7f:ee:b8:24:c0
         interface fc1/9 swwn 20:00:54:7f:ee:b8:24:c0
         interface fc1/10 swwn 20:00:54:7f:ee:b8:24:c0
         interface fc1/11 swwn 20:00:54:7f:ee:b8:24:c0
     FC_switch_B_1#
