dedicated crash dump device

Hello Guys,
I need a little help here. I have been studying crash dump and per what I am reading, you can dedicate a slice to use as a dump device. Now when you dedicate this slice, do you have to :

1) create a mount point?
2) add entry in /etc/vfstab?
3) is this slice wu or wm?
4) should it mount at boot?
5) should it be fsck?

I really appreciate your help guys.

Thanks lots

1) no
2) no
3) can be either
4) no
5) no

Just create slice in format and then specify it in dumpadm command. More on this topic can be found here: http://docs.oracle.com/cd/E19253-01/817-0403/tscrashdumps-40145/index.html

@ bartus11 : Good stuff . Really good stuff. Thanks a million.

If you use ZFS you can create separate ZFS dataset on which dump files will be created after dump is created. Using dumpadm(1) command you can change these options.
