Operating System InstallationΒΆ

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:

xcatdebugmode 0 1 2
