NAME
swap - swap administrative interface
SYNOPSIS
/etc/swap -a swapdev swaplow swaplen
/etc/swap -d swapdev swaplow
/etc/swap -l
DESCRIPTION
swap provides a method of adding, deleting, and monitoring
the system swap areas used by the memory manager. The
following options are recognized:
-a Add the specified swap area. swapdev is the name of
block special device, e.g., /dev/dsk/1s0. swaplow is
the offset in 512-byte blocks into the device where the
swap area should begin. swaplen is the length of the
swap area in 512-byte blocks. This option can only be
used by the super-user. Swap areas are normally added
by the system start up routine /etc/rc when going into
multi-user mode.
-d Delete the specified swap area. swapdev is the name of
block special device, e.g., /dev/dsk/1s0. swaplow is
the offset in 512-byte blocks into the device where the
swap area should begin. Using this option marks the
swap area as "being deleted." The system will not
allocate any new blocks from the area, and will try to
free swap blocks from it. The area will remain in use
until all blocks from it are freed. This option can
only be used by the super-user.
-l List the status of all the swap areas. The output has
four columns:
DEV The swapdev special file for the swap area if one
can be found in the /dev/dsk or /dev directories,
and its major/minor device number in decimal.
LOW The swaplow value for the area in 512-byte blocks.
LEN The swaplen value for the area in 512-byte blocks.
FREE The number of free 512-byte blocks in the area.
If the swap area is being deleted, this column
will be marked (indel).
WARNINGS
No check is done to see if a swap area being added overlaps
with an existing swap area or file system.
