SWAP(ADM) UNIX System V
Name
swap - swap administrative interface
Syntax
/etc/swap -a swapdev swaplow swaplen
/etc/swap -d swapdev swaplow
/etc/swap -l
Description
The swap command 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
the 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 multiuser mode.
-d Delete the specified swap area. swapdev is the name of
a 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. 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.
Notes
No check is done to see if a swap area being added overlaps
with an existing swap area or file system.
