Cannot delete vlan.dat or any other files in the flash directory 3650

I'm thinking that I have a corrupt IOS.  But if I can't copy an new IOS from USB to flash, I probably will not have any better luck with hyperterm.  Is the switch just worthless??

 

switch:

switch: dir flash:
Directory of flash:/

2 -rwx 2002 <date> config.text
3 -rwx 2356 <date> vlan.dat
4 -rwx 8188 <date> config.old

6 -rwx 1938 <date> private-config.text
7 drwx 512 <date> c3560c405ex-universalk9-mz.122-55.EX 2

  - Try fsck flash0:

Thanks for replying Marce1000, the fsck didn't really state anything useful. I posted the results below.

Hi,

erase startup-config
delete flash:vlan.dat
Reload

You were assuming that I could log in to the switch.  None of the data in the query reflected that I was in the priv exec mode.

So I learned through trial and error that if you are in the SWITCH: mode, to delete files the statement must be written like this:

switch:  del flash: vlan.dat 

DUH moment.

3850 switch does not use the delete flash:config.text or delete flash:vlan.dat like the earlier/simpler IOS does to erase the switch configuration and password. Instead the configuration and password are bypassed in switch: mode with the command SWITCH_IGNORE_STARTUP_CFG=1

switch:SWITCH_IGNORE_STARTUP_CFG=1

switch:reset

 
As Leo Laohoo points out in other posts
 
  1. Power down the switch. 
  2. Hold the Mode button. 
  3. Keep holding the button and apply power. 
  4. Keep holding down the Mode button for another 45 seconds and then release
  5. See if the console goes to ROMMON or not. 
  6. If in console, enter this command:  SWITCH_IGNORE_STARTUP_CFG=1
  7. Reload the switch (use the power cable). 
  8. Go to enable mode and enter the following command:  factory-reset all

WARNING:  This command will delete everything in the flash, including the IOS.
