Bad disk replacement procedure

I have TSM server 3.7.4.0 on AIX 4.3.3.  Have DB and Log mirrored
through TSM and not OS.  The other day we lost one of the internal
SSA disks that the DB is on.  (In all my years of AIX and several years
of TSM, I have never lost a disk - except on a small system that I had
to restore completely.)

I called IBM when the CE showed up with a replacement.  We had to
remove the disk and the filesystem that the DB mirror was on, install
new disk and then recreate the fs and remake the mirrors again!

In one way not a problem because TSM stayed up all this time and
nothing was lost.  But the time spent doing this I thought was long.
I know OS mirroring would have been much simpler to replace disk,
but everything I have read or heard says TSM mirroring is better for
other reasons.

Is there a simpler way to replace a defective disk with TSM mirroring?
