System dump devices should not be mirrored. You usually create 2 of them separate on each hdisk in your rootvg using smit or mklv. One will be your primary, the other the secondary.

Check out this link or check the man page of mirrorvg to read up on it:

IBM Info Center - mirrorvg

Helpful commands are:
Code:
sysdumpdev -l
# etc... or
smitty dump
