 Hello,

Collecting a live coredump with savecore -L requires a dedicated dump device.

In this document:

Collecting System Crash Dump Images on Solaris[TM] 7 and later [ID 1004803.1]

there is an example to add a dumpdevice that is using mkfile but that generates an error that says dedicated dumpd device required.  I got it to work with using /dev/dsk/c*t*d*s* but it would be good to update this document accordingly. It would be also nice to update the title and make sure that the rest is all valid for S10.

# mkfile 5000M /var/tmp/Livecore/dumpdev

Howdy, Stranger!
