may include files which the operator has placed on the disk device such as PIE files or temporary

When preparing for the upgrade to the next version of the operating system, any old, non-operational
versions should be removed.
Remove old SMUs and old versions of the operating system files by executing the following admin
Step 2
commands:
RP/0/RP0/CPU0:router(admin)# show install inactive
Node 0/0/CPU0 [LC] [SDR: Owner]
