Re: ROMMON Flash_Init not working

mcbrown@eatontown.org · ‎08-19-2019

I have a Cisco 3650 that it booting into ROMMON. In ROMMON, when I run dir I am only seeing these:

switch: dir

xmodem[0]: (read-only)
null[1]: (read-write)
bs[3]: (read-only)
tftp[12]: (read-write)
usbflash0[13]: (read-write)

So I run flash_init and it seems to run successfully:

switch: flash_init
Initializing Flash...

flashfs[7]: 0 files, 1 directories
flashfs[7]: 0 orphaned files, 0 orphaned directories
flashfs[7]: Total bytes: 6784000
flashfs[7]: Bytes used: 1024
flashfs[7]: Bytes available: 6782976
flashfs[7]: flashfs fsck took 1 seconds....done Initializing Flash.

but if I run dir after the flash_init I still don't see flash:

switch: dir

List of filesystems currently registered:

xmodem[0]: (read-only)
null[1]: (read-write)
bs[3]: (read-only)
tftp[12]: (read-write)
usbflash0[13]: (read-write)

I have the bin image on the usb drive and tried booting to that image but get the following:

switch: boot usbflash0:cat3k_caa-universalk9.16.09.03a.SPA.bin
loading usbflash0:cat3k_caa-universalk9.16.09.03a.SPA.bin
Reading full image into memory...read: premature eof
usbflash0:cat3k_caa-universalk9.16.09.03a.SPA.bin: short read: bad mzip file

Error loading "usbflash0:cat3k_caa-universalk9.16.09.03a.SPA.bin"

Interrupt within 5 seconds to abort boot process.
Boot process failed...

Any ideas on how I can get this up?

Thanks.

Hello mcbrown,

try to boot using a TFTP server on your PC connected to the switch with a LAN cable.

follow the instructions on this document

https://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst3650/software/release/16-1/configuration_guide/b_161_consolidated_3650_cg/b_161_consolidated_3650_cg_chapter_01101001.html?dtid=osscdc000283#task_1099467

Once you are able to boot with an IOS image you can try to format the flash: this might recover it or not.

Hope to help

Giuseppe

Error message means the IOS file is corrupt.

Go to the Cisco website and download the firmware again.

IMPORTANT: Make sure you compare the MD5 hash value of the file downloaded against the MD5 hash value found in the Cisco website.

And then read this: Emergency Recovery

Hello Leo,

thanks for having seen the issue with the file image on the USB drive,

I admit I have missed it.

Best Regards

Giuseppe

Organize for an RMA. The switch is dead.
