You can allocate secondary swap to logical volumes or disk
sections dynamically, using either SAM or the swapon
command. See swapon(1M) for more information.
Dynamic allocation means that you can make these changes while the
system is running without configuring them into the system. However,
you cannot modify or remove device swap without rebooting. You remove
device swap with SAM, or by editing /etc/fstab
to remove the swap entry, followed by a system reboot. You modify
device swap by re-adding a new entry into /etc/fstab
after having removed the original entry.
In order to configure secondary swap, use SAM to set up file
system swap. File system swap is always secondary swap.
