How do I avoid receiving the “Failed to process kickstart image. Pre-Upgrade check failed” error message when upgrading the image on a Nexus 7000 Interruptor de série?

One potential reason for receiving this error message is if the file name specified is not correct.

Por exemplo:

switch#install all kickstart bootflash:n7000-sl-kickstart.5.1.1a.bin system
    bootflash:n7000-sl-dk9.5.1.1a.bin

In this example, the file name contains “sl” (lowercase letter l) instead of “s1” (number 1).
