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.

Steps

  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 following topics, skipping the steps for configuring zoning on the switch.

      Fabric-attached MetroCluster installation and configuration

      Stretch MetroCluster installation and configuration

    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 this example) verify that the ISL's are online:

      switchshow

      FC_switch_A_1:admin> switchshow
switchName: FC_switch_A_1
switchType: 71.2
switchState:Online
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

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.

Steps

  1. Configure the switch:

    1. Refer to Fabric-attached MetroCluster installation and configuration

    2. Follow the steps for configuring the switch in 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.

    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.

    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

    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

  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 fc1/11 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.

    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

    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

    Note AFF A700 and FAS9000 systems support four FC-VI ports. You must remove all four ports from the FC-VI zone.

    • 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

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

    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

  2. Verify that the zoning is properly configured: show zone

    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
