NAME

prescripts - a table in the xCAT database.

SYNOPSIS

prescripts Attributes: node, begin, end, comments, disable

DESCRIPTION

The scripts that will be run at the beginning and the end of the nodeset(Linux), nimnodeset(AIX) or mkdsklsnode(AIX) command.

prescripts Attributes:

node

The node name or group name.

begin

The scripts to be run at the beginning of the nodeset(Linux), nimnodeset(AIX) or mkdsklsnode(AIX) command.

The format is:

[action1:]s1,s2…[| action2:s3,s4,s5…]

where:

• action1 and action2 for Linux are the nodeset actions specified in the command. For AIX, action1 and action1 can be ‘diskless’ for mkdsklsnode command’ and ‘standalone for nimnodeset command.
• s1 and s2 are the scripts to run for action1 in order.
• s3, s4, and s5 are the scripts to run for actions2.

If actions are omitted, the scripts apply to all actions. Examples:

myscript1,myscript2 (all actions) diskless:myscript1,myscript2 (AIX) install:myscript1,myscript2|netboot:myscript3 (Linux)

All the scripts should be copied to /install/prescripts directory. The following two environment variables will be passed to each script:

NODES a coma separated list of node names that need to run the script for ACTION current nodeset action.

If ‘#xCAT setting:MAX_INSTANCE=number’ is specified in the script, the script will get invoked for each node in parallel, but no more than number of instances will be invoked at at a time. If it is not specified, the script will be invoked once for all the nodes.

end

The scripts to be run at the end of the nodeset(Linux), nimnodeset(AIX),or mkdsklsnode(AIX) command. The format is the same as the ‘begin’ column.

comments
