The ability to access the installer or to collect logs during the installation process can be helpful when debugging installation problems.
A new attribute is provided in the site table called xcatdebugmode.
- xcatdebugmode=0: Diagnostic entries will be shown in corresponding log files.
- xcatdebugmode=1: Diagnostic entries will be shown in corresponding log files and debug port will be opened.
- xcatdebugmode=2: Diagnostic entries will be shown in corresponding log files, debug port will be opened and SSH access is enabled.
Supported OS:
- RHEL: 6.7 and above
- SLES: 11.4 and above
- UBT: 14.04.3 and above
The following behavior is supported during OS installation:
+-----------------+--------------+--------------+--------------+ 0 | 1 | 2 | +-----------------+----+----+----+----+----+----+----+----+----+ | SLESRHELUBT SLES +=================+====+====+====+====+====+====+====+====+====+ | Log Collecting | Y | Y | Y | Y | Y | Y | Y | Y | Y | +-----------------+----+----+----+----+----+----+----+----+----+ N | N | N | Y | Y | Y | Y | Y | Y | +-----------------+----+----+----+----+----+----+----+----+----+ | SSH Access | N | N | N | N | N | N | Y | Y | Y | +-----------------+----+----+----+----+----+----+----+----+----+
- Y - the behavior is supported by OS at specified xcatdebugmode level.
- N - the behavior is not supported.
Next chapter introduces the procedures on how to troubleshoot operating system installation.
