Elaine,
Very bizarre problem you're having. I have no problems on either of my
x4500s. One on 10u6 and one on indiana snv_101b_rc2.
Time on Sol 10u6:
- Just running hd
real 0m25.599s
user 0m0.021s
sys 0m2.376s
Time on OS snv_101b_rc2
- Just running hd
real 0m27.565s
user 0m0.050s
sys 0m1.184s
Only running indiana for the up to date cifs server which does ACLs
properly. I haven't done anything but install hd, I did nothing to
'make them work'.
Regards,

I've got a fresh install of 101a on a thumper with 48 disks and zfs
with one large 46 drive raidz2 pool. It has no load at the moment.
My problem is that the SUNWhd tools are excrutiatingly slow, by
excrutiating I mean that the command : "/opt/SUNWhd/hd/bin/hdadm
write_cache display all" takes three hours to iterate over the 48
drives which, I suspect, is not the expected time for such a command
to take.
I've hunted around and, while I've seen a few pointers to certain
thumpers in a SN range having performance issues, this thumper is
not in that range, nor is it running 10u5 or u6.
I've come up empty for an explanation so I thought I'd ask here
since I know there are some issues with zfs and caching, e.g. the
ARC cache, but I'm unclear as to which are currently solved in 101a
and which aren't. It could be a simple configuration issue, but I'm
unfamiliar with the hardware and would welcome any suggestions or
pointers.
