I have a 6513 Sup2 MFSC2. I am upgrading from 12.1(26) to 12.2(18). The flash is 64M ram is 256M. Flash is ATA.
Image requires 64M, so it must go into the flash card. You must format the card using the current version of 12.1(26) and then copy ftp: disk0: with the 12.2(18) image.
You clear the "boot system" variable and put in the pointer to the new image in flash.
The image couldn't be booted. I then booted from an old 12.1(19) in the bootflash. At this point the flash couldn't be read with a "dir" command. ROMMON itself couldn't read it either.
I formated the flash using another 6513 running 12.2(18) image and then both the rommon and 12.1(19) could read the flash (I just couldn't boot the image at that point.
It got late last night and I just recovered the old IOS version and got the switch back up.
Has anyone seen this problem?
