Upgrade IOS VSS 6509

good afternoon

i need you help

I have 2 switch 6509-E running vss

I need to update the ios version of the sxi4 to sxi14,,,,,, the problem is I have no redundancy with the remote host that manages the vss.

ie the host is connected to the switch 1 only

I am asking me to update them via console each separate chassis.

please what would be the most correct way ---- FSU --- eFSU ,,,,  please what would be the most correct way.

Hi,

If the hosts are connected to only one of the switches, there is no way to upgrade and not to have down time.  The 6509 takes about 10 minutes to reboot.  So, you will have down time during that window.  The best way is to have a maintenance window and do it during off hours.

Hi!

This is possible. Please refer to the following steps:

- Copy IOS image to each supervisor bootdisk. (Active supervisor and the standby one).

- Now point the boot variable of both supervisors to the new IOS image.

- Redundancy reload the standby supervisor.

- When the standby comes back reload the active supervisor.

There should be a brief downtime, so it is always recommended to do it in a maintenance window.

If you need a more detailed instructions please let me know.

Hope it helps, best regards!
