Understanding the Local File System
The Switch Processor Card (SPC)/System Management Card (SMC) provides control and management for the system.
The local file system is made up of files that are stored on one or more of the following:
- A CompactFlash card, located on the circuit board of the SPC/SMC, is the default storage media for
the operating system software image, CLI configuration, and crash log files used by the system.
- This device is available when an ATA Type I or Type II PCMCIA card is inserted into PC-Card
Slot 1 (upper slot) on the front panel of the SPC/SMC.
- This device is available when an ATA Type I or Type II PCMCIA card is inserted into PC-Card
Slot 2 (lower slot) on the SPC‘s front panel. Note that this option is not available for use with the SMC.
/hd-raid: This device is the hard drive installed on the SMC. Disk names ―hd-local1‖ and ―hd-remote1‖ are used
on ASR 5000s. An XFS-formatted RAID disk is mounted on ―/mnt/hd-raid‖. Users can gain access to part of it
from either ―/hd-raid‖ or ―/mnt/user/hd-raid‖.
from either ―/hd-raid‖ or ―/mnt/user/hd-raid‖.
Important:
For this release, local filesystem access is to master SMC only.
File Types Used by the Local File System
The following file types can be located in the local file system:
Operating System Software Image File: This binary file type is identified by its .bin extension. The file is the
operating system that is loaded by the system upon startup or reloading. This is an executable, read-only file
that cannot be modified by end users.
that cannot be modified by end users.
Important:
The ST16 and ASR 5000 platforms require different software image files. The
name of the image file indicates whether it is intended for use on an ST16 or an ASR 5000. A file
intended for use on an ST16 uses the convention xxxxx.st16.bin where xxxxx is the software build
information. Alternatively, a file intended for use on an ASR 5000 uses the convention
xxxxx.asr5000.bin.
intended for use on an ST16 uses the convention xxxxx.st16.bin where xxxxx is the software build
information. Alternatively, a file intended for use on an ASR 5000 uses the convention
xxxxx.asr5000.bin.
CLI Configuration File: This file type is identified by its.cfg extension. These are text files that contain CLI
commands that work in conjunction with the operating system software image. These files determine services
to be provided, hardware and software configurations, and other functions performed by the system. The files
are typically created by the end user. You can modify the files both on and off-line and use descriptive long
filenames.

System File: Only one file identified by a .sys extension is used by the system. The boot.sys file contains
system-specific information, which describes how the system locates, and in what priority it loads, file groups
(paired .bin and .cfg files) from its boot stack.
