I was trying to configure stackwise virtual for c9500-40x switch for new deployment. but command was not available while entering it.
When i checked version of the switch i found it is 16.6.4 version and this not supporting in C9500-40x. so I upgraded it to version fuji 16.9.3 using the procedure
then i applied stackwise-virtual
int range te1/0/39, te1/0/40
stackwise-virtual link 1
first i reloaded first switch then after making sure first switch(active) getting restarted i restarted second one(standby).
but first switch which was supposed to be active didnt boot up as expected
instead it went to switch: mode and stucked there.
second switch booted without any issue.
let me know why this is happened. how to move further?
i checked from this stage dir bootflash: and i can see the fuji files there. which file need to boot if i want to boot.
but fuji i cannot see bin file after installing it....

Alternatively, instead of booting up the IOS from TFTP, one can use a supported USB thumb drive and issue the command "emergency-install usbflash0:IOS_filename.bin".
IMPORTANT: After the switch as rebooted up in Bundle Mode, unpack the IOS into the flash using Install Mode.
sorry i didnt noticed the link. after my collegue checked the logs he was telling motherboard failed.. how come that happened?
If motherboard failed will it go to switch: rommon mode??? he checked the log and telling its some motherboard issue. for me i felt it firmware crashed.
while doing the hardware checking failed switch bootstrap got upgraded to 16.9.X unknowingly and second switch bootstrap is in 16.6 version. will that make problem for stackwise-virtual if it failed switch got up?
As I told you. its suddenly get into switch: thats all. nothing else
So what you're saying is once you apply power, the switches goes straight into "switch:". If this is the case, then raise a TAC Case and organize an RMA.
NOTE: I have never seen a Catalyst 9K go straight into "switch:" without going through ROMMON.
