Owner's Manual

• To Install DSET on Microsoft Windows Server 2008 or later, Microsoft Windows Vista or newer,
run the DSET installer with elevated privileges using
"Run As" option.
• To install Remote Provider, Windows Management Instrumentation (WMI) service must be
running.
− If WMI is stopped, DSET starts WMI automatically and continues with installation.
− If WMI is disabled, installation of DSET terminates with an error message.
For Linux
• You need to be logged in as the root user.
• Enable SSH services for remote report collection from Linux systems.
• Make sure that the user credentials supplied for remote report collection can initiate SSH
connection and have root privileges.
NOTE: For Linux CIMOM, the default port 5988 (for http) or 5989 (for https) is used by the system to install Remote
Provider. If custom ports are used, update the configuration file available at /opt/dell/advdiags/dset/config/dset.cfg.
For silent installation:
On Linux Operating system for Silent installation of DSET application, CIMOM (SFCB or Open Pegasus) should
already be installed.
To install SFCB:
1. Locate the SFCB rpm from the Operating System Media.
2. Install SFCB rpm using "rpm -ivh sblim-sfcb-*.rpm"
3. Try to perform DSET silent installation.
To install Top-Pegasus:
1. Locate the Tog-Pegasus rpm from the Operating System Media.
2. Install Tog-Pegasus using "rpm -ivh tog-pegasus-*.rpm"
3. Start the Pegasus services.
4. Try to perform DSET silent installation.
Probable reasons for provider installation failure
The DSET installation or collection is blocked on Red Hat Enterprise Linux operating system and CentOS, because
the SELinux option is enabled by default.
Resolution
Modify the security enforce feature using the command, setenforce 0.
Credential-less CIMOM authentication
When installing the DSET or collecting DSET report using DSET version 3.5.0 and earlier, you must enter password at
the command line interface on systems running Linux. If the credentials are correct and the CIMOM (SFCB or
OpenPegasus) authenticates, the installation or report collection process is successfully completed.
From DSET version 3.5.1 and later, DSET supports single sign-on for the logged-in user. That is, DSET does not
anymore require a password for its functioning. CIMOM accepts a client certificate while establishing the HTTPS
connection. If the certificate is signed by a trusted authority, a network connection is started. During installation,
DSET generates and deploys its own certificate and key which is used later. The access to these files is limited only
to the root user.
A brief description about the DSET installation or report collection process:
1. Collecting DSET report without providing any username or password: DSET tries for CIMOM connections
through certificates.
1. If the connection is successful, the report collection continues without prompting for a password.
2. If the connection is unsuccessful, DSET asks whether or not you want to provide password and
continue.
