Chapter 1 Software Packaging and Architecture Processes Overview If you run into a file system not listed in Table 1-3, enter the? help option or see the copy command reference for additional information on that file system. Autogenerated File Directories and Files This section discusses the autogenerated files and directories that might appear on your Cisco ASR 1000 Series Routers, and how the files in these directories can be managed. Table 1-4 provides a list and descriptions of autogenerated files on the Cisco ASR 1000 Series Routers. Table 1-4 Autogenerated Files File or Directory Description crashinfo files A crashinfo file may appear in the bootflash: or harddisk: file system. These files provide descriptive information of a crash and may be useful for tuning or troubleshooting purposes, but the files are not part of router operations and can be erased without impacting the functioning of the router. core directory The storage area for.core files. If this directory is erased, it will automatically regenerate itself at bootup. The .core files in this directory can be erased without impacting any router functionality, but the directory itself should not be erased. lost+found directory This directory is created on bootup if a system check is performed. Its appearance is completely normal and does not indicate any issues with the router. tracelogs directory The storage area for trace files. Trace files are useful for troubleshooting; if the IOS process fails, for instance, users or troubleshooting personnel can access trace files using diagnostic mode to gather information related to the IOS failure. Trace files, however, are not part of router operations and can be erased without impacting the router's performance. Important Notes About Autogenerated Directories The important information about autogenerated directories include: • Any autogenerated file on the bootflash: directory should not be deleted, renamed, moved, or altered in any way unless directed by customer support. Altering autogenerating files on the bootflash: can have unpredictable consequences for system performance. • Crashinfo, core, and trace files can be deleted, but the core and tracelog directories that are automatically part of the harddisk: file system should not be deleted.
