Unsetting the Boot Parameter from ROMMON Using Console

Unsetting the Boot Parameter from ROMMON Using Console

This procedure provides instructions to unset the boot parameter variables from ROMMON using Supervisor Engine 7-E console.

The following are the boot parameters available:

  • BootParam1
  • BootParam2
  • BootParam3
  • BootParam4
  • BootMode

Note


The boot parameters can also be changed from IOS-XE CLI with certain releases by following the procedures mentioned in the Unsetting the Boot Parameter Using IOS Command Line Interface document.


Important:

You must perform this procedure on both active and standby Supervisor Engine 7-E card because this procedure is applicable only for the current active Cisco RF Gateway 10 Supervisor Engine 7-E. Hence you need to repeat this procedure on the standby Supervisor Engine 7-E card as well.

Before You Begin
  • Ensure that you have access to the Cisco RF Gateway 10 Supervisor Engine 7-E Slot 1 and Slot 2 console ports.
  • Verify if the Cisco RF Gateway 10 IOS XE software image exists and is accessible.
    
    RFGW-10#dir bootflash:*.bin
    RFGW-10#dir slavebootflash:*.bin
    
    
    

    Note


    The Cisco RF Gateway 10 IOS XE software image can be loaded from bootflash: or remote server.
Procedure
    Step 1   Connect to Cisco RF Gateway 10 Supervisor Engine 7-E slot 1 and slot 2 through console.
    Step 2   enable
    Enables privileged EXEC mode in the active supervisor console.
    • Enter your password if prompted.


    Example:
    RFGW-10> enable
    
    
    Step 3   Verify if the boot parameter with ip=::::nova:eth0:off rw disableautoreboot is set using the show platform environment variables command.

    Example:
    RFGW-10# show platform environment variables 
    PS1="rommon ! >" 
    SupportedFeatures="1" 
    SkipDiagsAlways="1" 
    CodeSignDisable="1"
    BootParam1="ip=::::nova:eth0:off rw disableautoreboot"
    BootParam2="BootMode=0" 
    ConfigReg="0x2102" 
    DiagMonitorAction="Normal"
    RommonVer="15.0(1r)SQ(315)"
    BOOT="slot0:rfgwk10-entservicesk9.03.03.01.SQ.150-2.SQB1.
    bin,12;bootflash:rfgwk10-entservicesk9.03.02.00.SQ.150-2.SQA.bin,12;"
    RET_2_RTS="01:07:15 EST Tue Feb 4 2014"
    BootedFileName="slot0:rfgwk10-entservicesk9.03.03.01.SQ.150-2.SQB1.bin"
    ReqClearAutoboot="1"
    BootStatus="Success"
    RET_2_RCALTS=""
    
    
    
    
    Step 4   If the Cisco RF Gateway 10 Supervisor Engine 7-E is in the redundancy mode then ensure that the standby Cisco RF Gateway 10 Supervisor Engine 7-E is operational before reloading the current active Cisco RF Gateway 10 Supervisor Engine 7-E. Reload the active Cisco RF Gateway 10 Supervisor Engine 7-E using the reload or redundancy force-switchover command.

    Example:
     RFGW-10#  reload 
    Proceed with reload? [confirm]
    
    
    Note    After executing the reload command, the standby Cisco RF Gateway 10 Supervisor Engine 7-E becomes the active Cisco RF Gateway 10 Supervisor Engine 7-E. The reload command triggers the active Cisco RF Gateway 10 Supervisor Engine 7-E reboot and not the full chassis reload.

    or



    Example:
    RFGW-10# redundancy force-switchover
    
    This will reload the active unit and force switchover to standby [confirm]
    Preparing for switchover..
    
    
    
    
    Step 5   Press Ctrl-C on the Cisco RF Gateway 10 Supervisor Engine 7-E console to stop the boot process to enter ROMMON mode in console connection.

    Example:
    Restarting system.

    Step 6   Unset the boot parameter using the unset bootparamvariable command.
    • BootParamvariable - The boot parameter variables. The following are the boot Parameter variables available:
      • BootParam1
      • BootParam2
      • BootParam3
      • BootParam4
      • BootMode


    Example:
    rommon1> unset BootParam1
    rommon2> unset BootParam2
    rommon3> unset BootParam3
    rommon4> unset BootParam4
    
    
    
    Step 7   Ensure that the boot parameter variables are unset using the set command.

    Example:
    rommon> set

    Step 8   Boot the Cisco RF Gateway 10 IOS XE software image from the bootflash:

    Example:
    rommon5> boot bootflash:rfgwk10-entservicesk9.03.03.01.SQ.150-2.SQB1.bin
    
    Step 9   Repeat steps Step 1 to Step 8 on new active supervisor console.
    Step 10   Verify if the correct version of IOS is on both Supervisor Engine 7-E cards, they are in SSO Redundancy mode.
