I have been going through various documents on Cisco to find a procedure to upgrade Cisco 6500 VSS using ISSU. But unfortunately the information available in the documents is little different and thats why I am confused.
Assuming that Switch 1 is active and Switch 2 is standby, Do I need to use the following command
issu loadversion 1/5 sup-bootdisk:xyz.bin 2/5 slavesup-bootdisk:xyz.bin
issu loadversion 2/5 slavesup-bootdisk:xyz.bin
I understand next command will be
issu runversion 2/5 slavesup-bootdisk:xyz
And after accepting the version on 2/5, the last command will be
issue commitversion 1/5 slavesup-bootdisk:xyz
Any help is appreciated!!
You issue the loadversion command to start the upgrade process on the stand-by switch.
Here is the upgrade procedure:
Load the New Image to the VSS Standby Chassis
Enter the issu loadversioncommand to start the upgrade process. In this step, the VSS standby chassis reboots, reloads with the new image, and initializes as the VSS standby chassis in SSO redundancy mode, running the new image. This step is complete when the chassis configuration is synchronized, as indicated by the "Bulk sync succeeded" message.
