I am trying to configure a 3750G that has been sitting on the shelf for several months and am getting the following error -
% Error: Unable to create flash:/microcode_update % Error: It must not already exist
Normally, getting an error during POST isnt a good thing. My first thought was that flash was corrupted or flagged RO somehow. I did fsck flash: with no change. I next tried fsck /test flash:. It tested 77 blocks and performed 0 erasures. It had been running for about 15 minutes with no problems reported so far. Multiple reboots of the switch still report the same error.
I have reviewed the history of what I have done on this switch and finally think I found the problem. I noticed a microcode_update directory that I am not used to see on a 3750. Deleted the directory using the rmdir command and rebooted the switch. On reboot, I noticed that a front_end/ directory was listed as being created as well as fe_type_1 and fe_type_2 were created. The switch now boots up without any errors.
Hope this helps some others who encounter this error.
Just edited my initial post about the same time as I found the problem and fix. Thanks for the confirmation.
What started all this was I was trying to do a password recovery because none of the passwords we have used in the past would get me into the switch. What I found after I got in was that this switch was part of a stack at some point because I see references to a second switch in the stack but only config details for the ports for the switch I have. Cleaning that up now.
