NAME

online, offline − bring processors online and offline

SYNOPSIS

/etc/online −N

/etc/online −S

/etc/online [ −a ] [ −v ] [ processor-number ... ]

/etc/offline [ −a ] [ −v ] [ processor-number ... ]

DESCRIPTION

Online −N causes the number of currently online processes to be printed.  This is very useful in shell scripts. 

Online −S causes a one line summary on the online processors to be printed.  Also very useful in shell scripts. 

Online causes the given processors to initialize and begin scheduling user processes.  Processors are numbered consecutively upward from zero.  If the −a option is present, all processors in the system are brought online. 

Offline removes the given processor[s] from the pool of processors available for work.  One processor is always left online.  If the −a option is present, all but one of the processors in the system are brought offline. 

Both online and offline display which processors are on and off line.  If the −v option is specified, any resulting changes in state (on or off line) are also displayed. 

Only the super-user can take processors on or off line.
