Oracle x86 Platforms: Keeping the Solaris HOSTID Permanent (Doc ID 1003919.1)

Last updated on MAY 09, 2022

Applies to:

Solaris Operating System - Version 9 9/02 U1 to 11.0 [Release 9.0 to 11.0]
All Platforms


In releases of Solaris[TM] Operating System for x86 Platforms, the hostid is generated by the operating system (O/S) during installation and stored in the /kernel/misc/sysinit (/kernel/misc/amd64/sysinit for 64-bit) archive for Solaris 10 and below and the /etc/hostid binary file for Solaris 11 and above. Hostid will thus change if the O/S is ever re-installed. In some cases it is necessary to keep the hostid permanent in order to have License(s) based on the hostid to work properly (ie: VxVM or Symantec Netbackup License).

This document describes the way to keep the hostid permanent.
