Removing MPI Manually

Occasionally a situation will develop where MPI either fails to install correctly or is corrupted in such a way that pkgrm (SVR4), or custom --> remove (SCO) cannot remove the package successfully.

The following procedure will remove MPI from the system manually.

  1. Remove the Device Drivers

    cd /etc/conf/bin

    if ISA or EISA Xi or Xe cards were installed:

    ./idinstall -d pcxx
    ./idinstall -d pcx1

    if Microchannel Xi or Xe cards were installed

    ./idinstall -d mcxx
    ./idinstall -d mcx1

    if Xr cards were installed

    ./idinstall -d pcxr
    ./idinstall -d pcr1

    if EPC/X C/X or X/em were installed

    ./idinstall -d epca [epc(b-h) may exist on some systems]

    ./idinstall -d epc1

  2. Remove the parts of MPI

    cd /usr/bin
    rm ./mpi ./dpa.Z ./dscreen ./ditty

    cd /etc
    rm ./dsinfo ./epcadl ./pcxrdl ./pcxxdl
    rm ./digi/*

    for SVR4

    cd /usr/include/sys
    rm ./stdigi.h rm ./dgdscr.h
    cd /usr/share/man
    rm ./man1/ditty.1
    rm ./man4/dsinfo.4

    for SCO

    rm /usr/include/sys/digi.h
    rm /usr/spool/lp/model/dumb.dg

  3. Relink the kernel

    cd /etc/conf/bin
