Upgrading to the PRP

Upgrading to the PRP With Rebooting the Router

If for any reason you cannot use High Availability, you should use the following procedure to upgrade from a GRP to a PRP.

Step 1 Remove the Flash disk from the PRP card and install it into slot 1 of the active GRP. The following message will be displayed; do not format the disk.

22:21:31: %PCMCIAFS-5-DIBERR: PCMCIA disk 1 is formatted from a different router or PC. A format in this router is required before an image can be booted from this device

Step 2

Verify the disk contents using the dir disk1: command.

 

Router# dir

disk1:

 

 

Directory of disk1:/

 

 

1 -rw-

17329392

Dec 3 2003 11:44:46 +00:00

 

c12kprp-p-mz.120-27.S

 

63832064 bytes total (46465024 bytes free)

Step 3 If the Cisco IOS version is not the one you need, delete the image from the disk using the delete disk1: filename command. If the image is correct, continue with Step 6.

Step 4 Use the copy tftp: disk1: command to copy onto the Flash disk the appropriate PRP image. PRP images are titled c12kprp-<feature set>-<compression>.120-<release id>. You will receive an error that the PRP image is not executable on the GRP. When prompted to abort the copy, type n.

Router# copy tftp: disk1:

Address or name of remote host [172.16.16.254]?

Source filename [c12kprp-boot-mz.120-26.4.S]? c12kprp-p-mz.120-26.4.SDestination filename [c12kprp-p-mz.120-26.4.S]?

Accessing tftp://172.16.16.254/c12kprp-p-mz.120-26.4.S...

%Warning: File not a valid executable for this system Abort Copy? [confirm] n

Step 5 To verify that the image has been copied correctly, verify the MD5 hash for the new image on disk1:. To do this, use the command verify /md5 disk1image-name. The resulting string should be compared against the MD5 hash value posted on the Software download page on Cisco.com.

Step 6 Remove any existing boot system commands from the running configuration by using the command no boot system.
