swap(ADM) 19 June 1992 swap(ADM) 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 spe- cial device, for example, /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 a block spe- cial device, for example, /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. Note No check is done to see if a swap area being added overlaps with an existing swap area or file system.
