Noting…unless of course you are me \ud83d\ude42<\/p>\n

Here’s the situation. We are doing user aggregation on a 6509 chassis. Due to cost considerations, we only put a single Sup in. We had a power supply failure which subsiquently killed the super…don’t ask me how, but it did. I quickly threw in a redundant sup720 I had to temporarily replace the dead sup32.<\/p>\n

Luckily I ordered the supervisor from Canvas and they replaced it. I’ve been trying to schedule the replacement install for about 9 months now…my sup32 baby was finally ready to be born, so away I went.<\/p>\n

I backed up the config from the temp sup, then cleared it. I then inserted my replacement sup32 and booted it…when it came up in…CatOS, aww what the poop!<\/p>\n

It’s been a million years since I’ve used CatOS, so I had to google how to put a management IP<\/a> on the thing.<\/p>\n

show interface\r\nset interface sc0 172.16.84.17 255.255.255.0 172.16.84.255<\/code><\/pre>\n
I then googled how one would go about converting from CatOS to IOS<\/a>.  I stepped through the process easily enough.  I uploaded IOS, cleared everything out and configured it to boot to Rommon.  Nice.<\/p>\n
When in rommon I issue the next command:<\/p>\n
dir disk0:<\/code><\/pre>\n
and I get an error.  No big deal, I uploaded my image to bootflash and to disk0…the fact that disk0 won’t read isn’t a deal breaker.  I then issue:<\/p>\n
dir bootflash:<\/code><\/pre>\n
and I get an error with a message stating<\/p>\n
Resetting .......<\/code><\/pre>\n
No matter what I do I can’t get any CF to read in disk0.  I try formatting from another router.  I try formatting then loading IOS…NOTHING WORKS!  I get fun errors like “cannot load the monitor library” and “cannot determine first file name on device “disk0”.
\nI even tried setting the confreg mode to “the boot helper image” and nothing happened.<\/p>\n
After much time and anger, I was pulling the supervisor out and noticed the the bootflash sitting there…So, I replaced it.  I then booted the chassis and issued:<\/p>\n
dir bootdisk:\r\nboot bootdisk:name-of-ios.bin<\/code><\/pre>\n
and BOOM.  There is the image.  Apparently the corrupted bootflash just bricked the router.<\/p>\n
Needless to say that I was relieved, but good lord could that have taken longer or been more frustrating?  Note to self, if bootflash is acting a fool, replace it immediately and save yourself some heartache.  <\/p>\n
