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
