WIPE(1) LAM TOOLS WIPE(1)
wipe - Shutdown LAM.
wipe [-bdhv] [-n <#>] [<bhost>]
-b Assume local and remote shell are the same. This means that only one remote
shell invocation 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.
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 prop-
erly. 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 variable. 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 exe-
cuting 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 success-
wipe -v mynodes
Shutdown LAM on the machines described in the boot schema, mynodes. Report about
important steps as they are done.
