DESCRIPTION

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. 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 boot/.

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 successfully complete.

EXAMPLES

wipe -v mynodes

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