Device Swap | HP-UX 11i Internals

Device swap is dedicated physical or logical disk volumes. These raw volumes are configured for exclusive use by the swap system. If logical volumes are used, you should attempt to have only one swap space per physical disk controller. It is much better to have one large volume than two smaller ones sharing the same spindle.

It is a common practice to also configure swap devices as dump devices; this may be done either through inclusion in the kernel's "system" file when the kernel is being built or through lines placed in the /etc/fstab file. The use of the /etc/fstab file gives you more control and makes it easier to modify your configuration. If a swap area is added to /etc/fstab it may be activated by issuing the swapon a command. If a swap area definition is being removed from /etc/fstab a system reboot is required to halt its use. There is no swapoff command for HP-UX.
