Hi Dan,
Can you describe what you are trying to recover from with more details
because we can't quite follow what steps might have lead to this
scenario.
For example, your hdc pool had two disks, c1t0d0s0 and c8t1d0s0,
and your rpool has c8t0d0s0 so s8t0d0s0 cannot be wiped clean.
Maybe you mean c8t1d0s0 is now relabeled (with labelfix) and
reconnected for hdc but c1t0d0s0 is still corrupted so the hdc pool
cannot be re-imported is my guess...
Thanks,
Cindy

I had to use the labelfix hack (and I had to recompile it at that) on 1/2 of an
old zpool. I made this change:
/* zio_checksum(ZIO_CHECKSUM_LABEL, &zc, buf, size); */
zio_checksum_table[ZIO_CHECKSUM_LABEL].ci_func[0](buf, size, &zc);
and I'm assuming [0] is the correct endianness, since afterwards I saw it come up with
"zpool import".
Unfortunately, I can't import it. Here's what happens:
# uname -a
SunOS neuromancer 5.11 snv_130 i86pc i386 i86pc
# zpool import
pool: hdc
id: 18323387294498987089
state: FAULTED
status: The pool was last accessed by another system.
action: The pool cannot be imported due to damaged devices or data.
The pool may be active on another system, but can be imported using
the '-f' flag.
see: http://www.sun.com/msg/ZFS-8000-EY
config:
hdc FAULTED corrupted data
mirror-0 DEGRADED
c1t0d0s0 FAULTED corrupted data
c8t1d0s0 ONLINE
# zpool import -f hdc
cannot import 'hdc': one or more devices is currently unavailable
Destroy and re-create the pool from
a backup source.
# zpool status
pool: rpool
state: ONLINE
scrub: none requested
config:
NAME STATE READ WRITE CKSUM
rpool ONLINE 0 0 0
c8t0d0s0 ONLINE 0 0 0
errors: No known data errors
#
Note that c1t0d0s0 was on the old system, and that it's now the (wiped clean)
c8t0d0s0. Any clues are, as always, welcome. I'd prefer not to restore my
saved zfs-send streams, so I'd like to get the import of the old root pool
(hdc) to work.
Thanks!
Dan McD.
