volcheck(1)							   User Commands						       volcheck(1)

NAME

       volcheck - checks for media in a drive and by default checks all floppy media

SYNOPSIS

       volcheck [-v] [-i secs] [-t secs] pathname

DESCRIPTION

       The  volcheck  utility tells volume management to look at each dev/pathname in sequence and determine if new media has been inserted in the
       drive.

       The default action is to volcheck all checkable media managed by volume management.

OPTIONS

       The following options are supported:

       -i secs	  Set the frequency of device checking to secs seconds.  The default is 2 seconds.  The minimum frequency is 1 second.

       -t secs	  Check the named device(s) for the next secs seconds.	The maximum number of seconds allowed is 28800, which is 8 hours. The fre-
		  quency of checking is specified by -i. There is no default total time.

       -v	  Verbose.

OPERANDS

       The following operands are supported:

       pathname    The path name of a media device.

EXAMPLES

       Example 1 A sample of the volcheck command.

       The following example

		 example% volcheck -v /dev/diskette
		 /dev/diskette has media

       asks volume management to examine the floppy drive for new media.

       The following example

		 example% volcheck -i 2 -t 600 /dev/diskette1 &

       asks volume management if there is a floppy in the floppy drive every 2 seconds for 600 seconds (10 minutes).

FILES

       /dev/volctl    volume management control port

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

WARNINGS

       Due  to a hardware limitation in many floppy drives, the act of checking for media causes mechanical action in the floppy drive.   Continu-
       ous polling of the floppy drive will cause the drive to wear out. It is recommended that polling the drive only be performed during periods
       of high use.
