Symptom

A Nexus 5000/5500 switch which has Fibre Channel(FC) license grace-period expired might boot to bash prompt after a reboot/reload/power cycle or a software crash. Following output would be seen on the console of the switch.

System is coming up ... Please wait ... System is coming up ... Please wait ... System is coming up ... Please wait ... bash-3.2#

Conditions

Usually seen after a reboot/reload/power cycle or a software crash in a switch which has Fibre Channel(FC) license grace-period expired.

Workaround

The switch gets into this state due to process not getting spawned. The switch can be recovered by breaking into boot sequence, getting into loader prompt and booting the system with fixed NX-OS versions(both kickstart and system images). Contact TAC if assistance is needed
