IOS upgrade of WS-C4500X-32 in VSS

Noovi

Hello Guys,
I am having WS-C4500X-32 which are deployed in VSS and i am planning IOS upgrade.
I have checked few community forums and cisco document and i am bit confused now, I found 2 options, can you please help to suggest which one is good?

Option1
 1.Copy the IOS from the TFTP server to the active unit using the command "copy tftp://<TFTP IP address>/IOS_filename.bin bootflash:";
2.  Copy the IOS from the TFTP server to the standby unit using the command "copy tftp://<TFTP IP address>/IOS_filename.bin slavebootflash:";
3.  Remove the old boot variable string:  no boot system flash
4.  Change to the new boot variable string:  boot system flash bootflash:IOS_filename.bin
5.  Change the config-registry value to 0x2102:  config-registry 0x2102
6.  Save the config.
7.  Reboot.  ( will reboot from active switch will upgrade both active and member switch?)

Option2
Same steps but during reboot , need to use below
1)Standby switch will be reloading for IOS upgrade in standby device.

  • redundancy reload peer
  • show module (after peer come up)

     we will verify current IOS in peer switch with show module command

2) Now master device will be reloaded for IOS upgrade.

  • redundancy force-switchover
    This will reload the active unit and force switchover to standby[confirm]

Any issues if do separate reload?

I am familiar with Option 1 because, if I am not mistaken, that is my procedure.  

Hi Leo,
Yes, but just want to confirm
Reboot.  ( will reboot from active switch will upgrade both active and member switch?)

When I upgrade VSS (4500 &/or 6500) I always use the "reboot" command.  I will never use the Cisco-recommended "redundancy" commands.  

When the "reload" command is used, both the Active and the Standby until will reload.  However, if both units are within the same location, I strongly recommend cold-reboot both units because it will clean out a lot of stuff that would remain in a "reload".
