NAME

presto_chango − Legato Prestoserve installation and removal script. 

SYNOPSIS

presto_chango [ −i ] [ −r ] [ −n ] [ −q ] [ −p prefix ]

DESCRIPTION

presto_chango is an interactive script that installs or removes the Prestoserve software.  The user is asked a series of questions (with suggested defaults), which direct the installation or removal process.  Unless you have a non-standard installation, simply press <RETURN> at each prompt. 

presto_chango automaticly selects the mode of operation, and shows all commands that modify the filesystem.  The first time presto_chango modifies a file, the original is saved with .prepresto appended to its name.  The installation process will accelerate the standard SunOS disk devices(xy, xd, and sd).  If you interrupt this script, you should rerun it, choosing the mode which was interrupted to complete the operation, or removal to clean up. 

OPTIONS

−i Force installation mode. 

−r Force removal mode. 

−q Do not show commands being executed which modify the filesystem. 

−n Do not actually modify any files--just show what would have been done.  The output generated does not always completely match what would have happened if the −n flag had not been specified, since some changes are dependent on others. 

−p prefix Only affect the disk devices with the specified prefix.  This option is used for configuring non-standard controllers, but can also be used for the standard controllers.  Only one −p can be specified per run of this script, but with this flag, both installation and removal is a cumulative process.  For example, to accelerate two devices, with prefixes "rf" and "rs", you would run:

% presto_chango -i -p rf

% presto_chango -i -p rs
