To view the current state of the IDM and verify it is online, use the show chassis slot_number command. To display
information about the CSS hard disk, use the show disk command. The information includes the size of the disk, the
space available, and the number of files, directories, and bad clusters on it.
Internal Disk Module Structure
The Internal Disk Module (IDM) contains the CSS software, which consists of the files to run the CSS including boot files,
directories for archiving and logging files, and MIB information. This software is pre-installed on the CSS IDM.
The CSS software is approximately 50 Mbytes in size. You can install a maximum
of four versions on your CSS. To view all versions installed on the CSS, use the
show installed-software command. To view the version currently running on
the CSS, use the version command.
From an FTP server, you can view the following directories on the IDM:
• The log directory contains the following log files:
-
boot.log - ASCII log of boot process
-
boot.bak - Backup of the previous boot log
-
sys.log - ASCII log of system events (logging to disk is enabled by default to subsystem all and level info)
-
sys.log.prev - Backup of the previous system log file (if any)
• The scripts directory contains default, profile, and sample scripts
• The core directory contains any core dumps created by the CSS
• The MIB directory contains MIB files which you can load into SNMP-compliant network management software
applications
Note:
When you view the CSS software directories installed on a network drive, more directories are listed than
those you can view on an IDM. These additional directories are reserved for internal use. Do not manipulate
the files in these directories.
