WARNINGS

On systems running VxVM 3.5, the swap volumes to be conﬁgured for system crash

dumps should be created with the usage type as swap during the creation of the

swap volume. Not doing so will cause dump corruption. You could use the -U option

of vxassist (1M) to do the same.

The output of crashconf is not designed to be parsed by applications or scripts, but

only to be read by humans. The output format may change without notice. Applica-

tions which require crash dump conﬁguration information should retrieve that infor-

mation using pstat(2).

Dump devices created by lvcreate(1M) must be contiguous (-Cy option) with bad

block relocation turned off (-rn option).
