Adding more information.

scan: none requested
config:

Hi all, I've been trying to solve an issue where there was a disk failure causing all sorts of issues including the df -h command hange at the rpool mount. I try using strace df -h and get the error: > sol10 # strace df -h
ERROR: tracer already exists
Hangs on rpool.
# df -h
rpool 134G 106K 51G 1% /rpool
^c
(hanging)

# zpool list homepool
NAME SIZE ALLOC FREE CAP HEALTH ALTROOT
homepool 99.5G 20.1G 79.4G 20% UNAVAIL -

replaced the bad disk with another one named:
# df -h /home-new/
Filesystem size used avail capacity Mounted on
/dev/dsk/c3t524A93780142DE18d13s6
123G 1.4G 120G 2% /home-new

Any ideas from anyone would be appreciated as this is a major production system and I need to clear the /export/home mount
