In order to provide as much room as possible on the disk, one can remove old files from the disk. This
may include files which the operator has placed on the disk device such as PIE files or temporary
directories that have been created.
When preparing for the upgrade to the next version of the operating system, any old, non-operational
versions should be removed.
Step 2 Remove old SMUs and old versions of the operating system files by executing the following admin
commands:
RP/0/RP0/CPU0:router(admin)# show install inactive
Node 0/0/CPU0 [LC] [SDR: Owner]
Boot Device: mem:
Inactive Packages:
disk0:hfr-fit-px-4.0.0.63I
disk0:hfr-infra-test-px-4.0.0.65I
disk0:hfr-upgrade-px-4.0.0.65I
disk0:hfr-fit-px-4.0.0.65I
disk0:hfr-cgn-px-4.0.0.63I
disk0:hfr-mpls-px-4.0.0.63I

disk0:hfr-diags-px-4.0.0.63I
disk0:hfr-diags-px-4.0.0.65I
Execute the install remove inactive test sync command first to show which packages will be removed
from the disk.
RP/0/RP0/CPU0:router(admin)#install remove inactive test sync
Info: This operation will remove the following packages:
Info: disk0:hfr-diags-px-4.0.0.65I
Info: disk0:hfr-diags-supp-4.0.0.65I
Info: disk0:hfr-doc-px-4.0.0.65I
Info: disk0:hfr-doc-supp-4.0.0.65I
Info: disk0:hfr-fit-px-4.0.0.65I

The install operation will continue asynchronously.
RP/0/RP0/CPU0:router(admin)#Install operation 192 completed successfully
Step 3 Ensure all active packages are 'committed', then issue the install commit command
RP/0/RP0/CPU0:router(admin)#install commit

Install operation 193 completed successfully at 07:10:46 UTC Wed Oct 13 2010.
If any node is not booting properly it has to be replaced or shut down using the hw-module power
disable location 0/1/cpu0 command executed while in admin mode
RP/0/RP0/CPU0:router(admin-config)#hw-module power disable location 0/1/cpu0
Step 4 Copy the running-configuration and admin-configuration to a temporary storage location. This could be
on a remote TFTP server or a device such as the harddisk: or disk0: present on the RP.
router#copy running-config tftp://…running_config.txt
