Brocade switch firmware upgrade hung with firmware version reporting as "Unknown"
Applies to
Brocade 6510 Switch
Issue
- While performing FOS upgrade from v7.4.1d -> v8.1.2k2 -> 8.2.3b, the switch stopped responding.
- Rebooting the switch will bring it up temporarily but not long enough to collect a supportsave.
- Switch cli is getting into hung state while running any commands.
-
The switch goes into not responding state during the process of firmware download and below error was observed after restarting the ssh
connection:
Raslog Module Initialisation failed
rc=-1
**************************************************************
