Upgrade Procedures for RPM-PR Cards
Step 10 To reorganize the bootflash so that the new boot software is loaded first when the BOOTLDR variable
is not set, complete the following steps:
a. Because all files that precede the new boot image in bootflash have to be deleted, copy bootflash
files you want to save to the PXM45 hard disk using the following command.
Router#copy bootflash:filename c:filename
b. Mark all the files that precede the new boot image in bootflash using the del bootflash: command
as shown in the following example:
Router#del bootflash:
Delete filename []? rpm-js-mz
Delete bootflash:rpm-js-mz? [confirm]
Router#
Tip To unmark a bootflash file so that it won’t be deleted when the squeeze flash: command is run,
enter the undelete <number> command, where number is the file number displayed in the
left-most column of the show flash: command display.
c. To delete all files that are marked for deletion from bootflash, enter the squeeze flash: command as
shown in the following example:
Router(boot)#squeeze flash:
All deleted files will be removed. Continue? [confirm]y
Squeeze operation may take a while. Continue? [confirm]
Squeeze of bootflash complete
d. Copy any previously saved bootflash files you want to use from the PXM45 hard disk using the
following command.
Router#copy c:filename bootflash:filename
You might want to copy previously saved configuration files back to bootflash, or you might want
to copy an older boot image to be used if the newer version becomes corrupt.
e. Enter the show flash: command to verify that the bootflash files are as you want them. The preferred
boot software should appear first in the list.
Caution If all bootable images are deleted from bootflash and the RPM-PR card is restarted, the card must be
returned to the factory to be reprogrammed. When you are done managing the bootflash, the show flash:
command should display at least one bootable image, and the image you want the card to boot from
should be the first bootable image in the list.
Tip If the show flash: command does not display a bootable image, copy a bootable image to
bootflash as described earlier in this procedure. You can continue to manage the bootflash, even
when there are no files in bootflash, until the router is restarted.
Step 11 When you are sure the bootflash is ready for use, you can enter the reload command to restart the
RPM-PR card, or you can upgrade the runtime software as described in the next section.
