Migrating a Single Chassis System to a Multi Chassis System (1+1)
The following upgrade procedure is for migrating a SC system to a 1+1 MC system. The MC system comprises, one LCC (LCC0) and one FCC (FCC0).
Before you begin
The following tasks need to be carried out for uprading a single chassis system to a 1+1 multi chassis configuration.
Login to Admin-VM using the root-system username and password.
Verify the status of the LCC0. The commands to be run on the XR VM are: show redundancy , show platform , show platform vm . The commands to be run on the Admin VM are: show platform , show chassis , show vm .
Verify the SMUs (for the upcoming release). The commands to be used are: show version , show install commit , show install active , show install inactive .
Verify the FPD. The commands to be used in the Admin VM are: show hw-module fpd .
If any FPD state indicates NEED UPGD or RLOAD REQ, then an FPD upgrade must be performed using the FPD upgrade commands.
Check the FCC0.
Connect the control ethernet cables between LCC0 and FCC0.
Add the chassis serial number in system admin configuration mode of LCC0 using the chassis serial serial-number rack rack-id command.
Switch on FCC0.
Verify the 1+1 MC chassis state using the show chassis and show platform commands in admin mode and the show platform command in XR mode.
Perform plane by plane upgrade of the fabric planes. The upgrade for plane 0 is discussed here in detail. Follow the same steps for plane 1, plane 2, plane 3.
