RPM-PR Bootflash Precautions

Chapter 5 Configuring the MGX RPM-PR

Booting the RPM-PR

The RPM-PR bootflash is used to store boot image, configuration and “run time” files. The Flash stores and accesses data sequentially, and the RPM-PR boot image must be the first file stored to successfully boot the card. Erasing the boot image or moving it from the first position on the Flash will cause the card to not boot.

The RPM boot image, which comes loaded on the Flash, will work for all RPM IOS images. Therefore, there is no reason to ever delete or move the factory installed boot image.

Note Erasing or moving the boot image can cause RPM-PR boot failure. When this happens, the RPM must be returned to Cisco and reflashed.

In order to avoid this unnecessary failure, requiring card servicing, you should

•Never erase the boot file from the RPM Flash

•Never change the position of the boot file on the RPM Flash

•Use care when “squeezing” the Flash to clean it up.

As long as the boot file remains intact in the first position on the flash, the RPM will successfully boot.

Verifying the IOS Files on Bootflash

Enter the show bootflash command to verify the IOS files on the bootflash. The following screen displays the RPM-PR command sequence.

Router#show bootflash:

Verifying the IOS Files on the PXM-45 x: Drive

The IOS image can be stored on the PXM-45 hard drive. To confirm this, make sure you are in the C:FW directory. Enter the ll command to list the contents of the directory. You should see a file with a name beginning with rpm-js-mz, which is the IOS image.

Tip Copy the RPM-PR Cisco IOS image into the RPM C: directory (not the E: directory) of the PXM-45 hard disk with the filename specified in the RPM-PR boot command.

The following screen displays the PXM C:FW content listing.

M8850_LA.8.PXM.a > cd FW

M8850_LA.8.PXM.a > ll
