Upgrade Procedures for RPM-PR and RPM-XF Cards
The boot software is stored in bootflash memory on the RPM card. To manage the software in bootflash,
you access it as if it were a hard disk. For example, in copy and delete file commands, files are identified
as bootflash:filename (which is similar to x:filename).
The following example shows a directory of bootflash contents:
Router(boot)#show flash:
-#- ED --type-- --crc--- -seek-- nlen -length- -----date/time------ name
1 .D config D4F7352A 40330 18 686 Jan 30 2001 18:18:41 auto_config_slot09
2 .D config CBF007C1 40660 9 688 Feb 22 2001 15:33:11 slot9.cnf
3 .. image F596869A 2973E8 27 2452744 Feb 28 2001 03:16:05
rpm-boot-mz_002.001.000.000
Note Although you can display directory contents with the dir bootflash: command, the show flash:
command provides more detail. Although bootflash and flash are separate entities on other Cisco
Routers, both terms refer to the same entity on the RPM.
In the example above, the numbers in the left column indicate the order in which the RPM will try to
load software. The second column shows that the first two files are marked for deletion (D). The last
column lists the names of the files stored in bootflash.
When managing the bootflash, consider the following facts:
• If the BOOTLDR variable is set and the RPM card is reset, the RPM card attempts to load the boot
software specified.
• If the BOOTLDR variable is not set and the RPM card is reset, the RPM card tries to load the first
bootable image in bootflash. The first bootable image is the image that appears first in the show
flash: command display, and this is usually the oldest file in bootflash. Therefore, if you do not use
the BOOTLDR variable, the bootflash contents must be reorganized each time you upgrade boot
software.
• The RPM card will not attempt to boot from automatic configuration files, which are named using
the format auto_config_slotnn, where nn represents a slot in which an RPM card is installed.
• If the image that RPM tries to load does not load, you can reset the RPM from the active PXM card
using the resetcd <slot> command.
• Files are not removed from bootflash until the squeeze flash: command is entered. If you delete a
file and do not enter squeeze flash:, the RPM card will still attempt to boot from the first image it
finds, whether it is marked for deletion or not.
Caution If all bootable images are deleted from bootflash, the card must be returned to the factory to be
reprogrammed.
