[SunHELP] adding/removing metadb replicas

[listmail]

I'm looking to get rid of c1t0d0sX metadb replicas, since the c1t0d0 
disk is no longer being used for my root mirror config. The "p,l,o" 
flags have me concerned since they do not show for the t4 and t5 drives 
as well.  The c1t5d0 and c1t4d0 replicas were added with metadb -a (no 
-f) after a local disk (c1t1d0) had failed.

Is there anything I need to do manually?  Will metadb -d c1t0d0s5 
c1t0d0s6 c1t0d0s7 suffice?

metadb -i
