cdslinvchk(8)						      System Manager's Manual						     cdslinvchk(8)

NAME
cdslinvchk - Checks the CDSL inventory of the base operating system and layered applications. SYNOPSIS
/usr/sbin/cdslinvchk [log_file_path] OPTIONS
The path name to a location for the log file. By default this will be /var/adm/cdsl_check_list. DESCRIPTION
Use the cdslinvchk script to verify the current inventory of Context Dependent Symbolic Links (CDSLs) on a running system. CDSLs are spe- cial symbolic links that enable a system to work in a cluster. If CDSLs are accidentally removed, your system will not function correctly in a cluster. While this is not a problem for stand-alone systems, you may not be able to add the system as a member of a working cluster at some future time. You can run this script at any time or configure it to run at system start-up, or as a cron task. When you invoke the script, it checks the CDSLs on the running system against CDSLs of the installed inventory in /usr/.smdb and the addi- tional entries in /var/adm/cdsl_admin.inv, and ensures that each target file exists on the system as a properly-constituted CDSL. If the check is successful, the following message is displayed and the script terminates: Successful CDSL inventory check If the script finds inconsistencies in the inventory, warning messages are displayed on your terminal and logged to the default log file at /var/adm/cdsl_check_list. You can specify an alternate location for the log fill if required. The script locates any modified, missing, or replaced CDSLs. Note that the previous copy of the log file is renamed and retained for reference and is renamed by appending to the filename. Refer to the System Administration guide for information on recreating any missing or broken CDSLs. Refer to the hier(5) reference page for an inventory of CDSLs. MESSAGES One or more of the following messages may be displayed and logged to the log file: Unable to create <pathname> report file -- the script was not able to create a log file. Check the target directory and security. Expected CDSL: <cdsl_pathname> -> <pathname> CDSL Target has been modified to: <pathname> CDSL has been replaced with <pathname> CDSL is missing Failed CDSL inventory check. See details in <log file> FILES
Additional inventory file entries. This file will not exist on all systems. The current and previous log files for inventory errors and messages SEE ALSO
Commands: cron(8) Others: hier(5) See also the System Administration guide for details of CDSLs cdslinvchk(8)
