Likewise....I always run an extendlv before performing a chfs. However,
even performing those steps in my scenario it still does not control
where the mirror will extend its copies to if there is not enough space
currently on the pv. We will try the map file feature in future lv
endeavors...thanks for the suggestion.

For an existing mirror, you can use a map file with extendlv to specify
the locations of new partitions added to both copies of the LV.
If you are using chfs directly to extend both the filesystem and the
underlying LV then it is not possible to control precisely where new
space will be allocated.
With mirrored filesystems, I nearly always do an extendlv followed by a
chfs.

you can use map-files with mklvcopy, too
or remove the mirror before extending and use the physical
volumes as a parameter when using mklvcopy again
as a third possibility you could use chpv -a n to prevent some
pv to be used for placement of mirrors

Subject: Mirroring question
Scenario: You have a created a logical volume. After the
creating the lv on one physical volume you then mirror that physical
volume to another physical volume. Say 2 months down the road you have
extended that logical volume to the point where it spills onto another
physical volume therefore extending your mirror over another pv as well.
Question: How can you control which pv the mirror is
extended to? Is this even possible?
