i ahve been told to reinstall the IOS to fix a GSR problem i am having..does that mean loading the code from a code server we have to my router one more time...or this is more like reload? i am just wondering what "reinstallation" exactly meant

Give us a 'sh run | i boot' and a 'sh ver' so we can answer as accurately as possible.

Your GRP or PRP has on-board bootflash and some form of swappable flash slots (I know GRP-B has two PCMCIA slots; don't have a PRPx to reference).  You may be booting your image from the bootflash or a slot/disk.  If someone is suggesting that you reinstall the IOS, you probably want to copy the image from CCO to a TFTP server and then onto your GSR into a different spot than the existing image, so that you can compare if the copy worked better.

Your "boot bootldr" and "boot system" commands will tell us how your GSR is booting.

You may also need to switch to a different image; whoever is telling you to reinstall the IOS image may also be suggesting you load an image with certain bugs fixed.

As a reminder, remember that ATA flash disks (and possibly Compact Flash cards, if the PRP takes those instead) are likely not directly bootable.  You'll need a boot loader image on a linear flash device (either the onboard bootflash or a PCMCIA linear flash card) and then have the GSR boot the full image.

Ah, a 6509, NOT a GSR.  You'll get much better help if you tell people the right platform.

One CF slot, no way the bootflash is big enough to hold an SXF image.

Two choices:
copy the image onto your existing disk with a different filename (so you can have old and new on the same card) and boot to that by removing your existing "boot system ..." line, adding a new "boot system <filename>" line, and restoring the old "boot system ..." line.  reload.


buy a new CF card, swap cards, copy the new image onto there, and reload.

The Sup720 can boot straight to a CF (AFAIK), so you don't need a boot loader image.

The GSR GRP can't boot straight to an ATA flash disk (same with the 7500 RSP1/2/4), so a boot loader image is needed IF you don't have enough contiguous linear flash space to store the images.
