As noted by another, Veritas is capable of this. I've included an
excerpt from the docs, below:
[begin vxassist man-page]
NAME
vxassist - create, mirror, backup, grow, shrink, and move
volumes
[...]
shrinkto and shrinkby
Decrease the length of the named volume to the length
specified by newlength (shrinkto), or by the length
specified by lengthchange (shrinkby). The new length
or change in length is specified as a standard Volume
Manager length [see vxintro(1M)]. The shrinkto opera-
tion fails if the new length is not less than the
current volume length.
[...end]
Of course, this only shrinks the whole volume, but it is my
understanding that at that point, you can re-arange the plexes so that
the disk you want to remove no longer has any plexes on it. It's ugly
and complex, but possible. It strikes me as very strange that a system
that's otherwise so flexible does not allow this. We've really hosed
ourselves because on one Filer (while attempting to set up a volume
that we could volcopy to), we accidentally added disks to the root
volume. So, now we have to do what? Re-install?
