WARNINGS

If swapctl() is used for conﬁguring primary swap, other methods for conﬁguring primary swap like

lvlnboot, vxvmboot, and system conﬁguration ﬁles (see lvlnboot(1M), vxvmboot (1M), and system(4)),

and PA HP-UX boot loader mechanism will become ineffective. In other words, if a device is conﬁgured for

primary swap using

swapctl(), then other device(s) that are conﬁgured for primary swap using the

above mentioned methods will not be effective.

The lvlnboot, vxvmboot, and system conﬁguration ﬁle methods for conﬁguring swap are deprecated

and will be obsoleted in future releases.
