SWAP(1M)  —  

 

NAME

swap − swap administrative interface

SYNOPSIS

/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. 

WARNINGS

No check is done to see if a swap area being added overlaps with an existing swap area or file system.
