wipe - Shutdown LAM.


SYNTAX

       wipe [-bdhv] [-n <#>] [<bhost>]


OPTIONS

       -b          Assume  local  and  remote shell are the same.
                   This means that only one remote shell  invoca­
                   tion is used to each node.  If -b is not used,
                   two remote shell invocations are used to  each
                   node.

       -d          Turn on debugging mode.  This implies -v.

       -h          Print the command help menu.

       -v          Be verbose.

       -n <#>      Wipe only the first <#> nodes.


DESCRIPTION

       This  command  has been deprecated in favor of the lamhalt
       command.  wipe should only be necessary if  lamhalt  fails
       and  is  unable  to  clean up the LAM run-time environment
       properly.  The wipe tool terminates the  LAM  software  on
       each  of  the  machines  specified  in  the  boot  schema,
       <bhost>.  wipe is the topology tool that terminates LAM on
       the  UNIX(tm) nodes of a multicomputer system.  It invokes
       tkill(1) on each machine.  See tkill(1) for a  description
       of how LAM is terminated on each node.

       The  <bhost> file is a LAM boot schema written in the host
       file syntax.  CPU counts in the boot schema are ignored by
       wipe.   See bhost(5).  Instead of the command line, a boot
       schema can be specified in the LAMBHOST environment  vari­
       able.   Otherwise a default file, bhost.def, is used.  LAM
       searches for <bhost> first in the local directory and then
       in the installation directory under etc/.

       wipe  does  not quit if a particular remote node cannot be
       reached or if tkill(1) fails on any node.   A  message  is
       printed  if  either of these failures occur, in which case
       the user should investigate the cause of failure  and,  if
       necessary, terminate LAM by manually executing tkill(1) on
       the problem node(s).  In extreme cases, the user may  have
       to terminate individual LAM processes with kill(1).

       wipe will terminate after a limited number of nodes if the
       -n option is given.  This is mainly intended  for  use  by
       lamboot(1),  which  invokes wipe when a boot does not suc­
       cessfully complete.

       wipe -v mynodes
           Shutdown LAM on the machines  described  in  the  boot
           schema, mynodes.  Report about important steps as they
           are done.
