Managing Directories

Procedure

• Run cd directory

  A directory is changed to a specified directory.

• Run pwd

  The current directory is displayed.

• Run dir [ /all ] [ filename ]

  Information about all files or a specified file is displayed.

  Either an absolute or relative path can be specified in this command.

  The following table describes files displayed in the command output.

  

  Files displayed depend on the system software version and service configurations. The following table lists only common files.

  The wildcard "*" can be used in the command.

  Table 1 Files displayed in the command output

  File Name	File Description
  $_checkpoint	File in which configuration rollback point information is saved.
  **.cc	Software version file.
  $_install_hpg	Directory where patches released with the software version are saved.
  $_install_mod	Directory where dynamic module packages are saved.
  $_license	Directory where activated licenses are backed up.
  $_security_info	Directory where the historical AAA user data is saved.
  $_system	Linux system-predefined directory where system scripts are saved.
  backup_bkp_elb.txt	Backup file of the backplane electronic label (E-label).
  backupelb.txt	Backup file of the E-Label of a specific board, which is generated after the board's E-Label is automatically read most recently.
  backupelable.txt	Backup file of the E-Label of a specific board, which is generated after the board's E-Label is read manually most recently.
  dbupgrade.log	Log file containing logs generated during each database upgrade.
  device.sys	System hardware configuration file.
  lcsbox	File that saves the names and content of activated GTL license files.
  lpustat	Directory where the statistics about discarded packets on interface board chips are saved. Interface boards periodically collect such statistics and report them to the main control board. The statistics are then saved in this directory.
  pmdata	Directory where the service performance data file is saved.
  security	Directory where SSL certificates are stored.
  logfile	Log file, occupying independent storage space.
  KPISTAT	Used to store collected KPI data.
  said	Used to store information generated during fault detection, diagnosis, and rectification on the SAID node.
  lost+found	File management module's file that is damaged and then restored during a device restart.
  **.zip/**.cfg/**.dat	System configuration file. For details, see the save command. After being compressed, log files are suffixed with .zip. Compressed log files are classified as follows: log_slot ID_time.log.zip: a common log file that is greater than or equal to a specified size. diaglog_slot ID_time.log.zip: a diagnostic log file that is greater than or equal to a specified size. To set the size of a log file, run the info-center logfile size command.
  *.pat	Patch file.
  lpustat.dat	Log file containing logs generated when packets are discarded due to a forwarding engine fault. The device automatically records data about lost packets in this case and saves the data to the lpustat directory on the CF card of the main control board as a structured hexadecimal file named lpustat.dat. As the lpustat.dat file is stored in hexadecimal format, it cannot be directly opened for viewing. To view this file, ask Huawei engineers to convert it into an lpustat.csv file in which data is displayed by time, slot ID, module, chip, fault ID, and fault information. When the remaining space of the CF card is less than or equal to 110 MB, the device no longer records packet loss logs.
  insegdroplog.log	Log file containing logs about packet loss during MPLS forwarding. The device automatically records packet loss data generated due to label table query failures that occur during label-based service forwarding. The device saves the data to the insegdroplog directory on the CF card of the main control board as a file named insegdroplog.log. When the insegdroplog.log file is greater than 8 MB, the device automatically compresses the file into an insegdroplog_timestamp.rar package and deletes the insegdroplog.log file. If new packet loss occurs, the device creates another insegdroplog.log file to record the data. The insegdroplog directory provides a maximum of 10 MB for log files. When the size of all log files in the directory exceeds 10 MB, the device deletes earliest log files to store new ones.

  The backcc directory is used to save backup files which can be used in case the primary files fail to be read. The backup file information is shown in Table 2.

  Table 2 Description of files in the backcc directory

  File Name	File Description
  *.pat	Patch file
  *.cfg	Configuration file
  *.cc	Software version file
  device.sys	Persistent data related to hardware configuration
  monlist_history.txt	Backup list file
  *.dat *.xml	License file
  persisSafMedia*.txt	Encrypted license data
  snmpsystemruninfo.bin	SNMP persistent information (engineboots record)
  vrpcfg.ini vrpfile.ini	Persistent data related to the startup software package, patch, configuration, PAF, or license file

• Run mkdir directory

  A directory is created.

• Run rename source-filename destination-filename

  The directory is renamed.

• Run rmdir directory

  A specified directory is deleted.
