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.
