It would be reasonable to think of a Sun Fire V480 as old hardware yes, but
not *very* old. I do have *very* old if you would like me to test there?
The server runs fine, is patched up to date. The UFS filesystem that was
used is actually the root filesystem and it is a metadevice mirror of
the two internal disks.

However I do also have :

Since I have a pile of fibre disks I can perhaps isolate one of
them and test with UFS on a single disk.
This one may do fine :
jupiter-sparc-SunOS5.10 # luxadm display 2000000087b10c29

I can try to isolate that and use it with UFS but no hurry, I have other
things to do also.
