Tru64 system stops with fan failure message

Tru64 system stops with fan failure message

Sept 01, 2015

Problem

Cannot boot Tru64 UNIX due to fan failure message.

Tru64 version 5.x shutdown with the message: "The system fan has failed and the system is shutting down now.".

Example:

...

The system fan has failed and the system is shutting down now.

 

Environmental Monitoring Daemon did not start...trying again

/sbin/rc3.d/S51envmon: 730 Terminated

/sbin/rc3.d/S50insightd: 680 Terminated

syncing disks... done

 

CPU 0: Halting... (transferring to monitor)

Solution

Tru64 temperature monitoring should be disabled or better not installed (if installing from scratch)

  • Boot single user

  • Mount / for read-write

  • Mount /usr

  • Force environmental daemon not to start at boot

  • Switch to multiuser mode by either entering "exit" or by pressing <CTRL-D>

    Detailed operations:

    Example1: bcheckrc will mount all filesystemsExample2: only / and /usr will be mounted

    P00>>>boot -flag s
    ....
    # bcheckrc
    # rcmgr set ENVMON_CONFIGURED 0
    # exit

    		P00>>>boot -flag s
    ....
    # mount -u /
    # mount /usr
     # rcmgr set ENVMON_CONFIGURED 0
    # exit
