I've had trouble with one of those (Dell PERC H200) in a Z68X-UD3H-B3
motherboard.  When it was inserted in any slot, the machine wouldn't
power on.  I put it in a Dell desktop I borrowed for a day and it worked
there.  Any idea as to what might be the trouble?  Couldn't even get it
working long enough to attempt to reflash its BIOS.

The machine would power on for a few seconds and immediately turn off.

 How about reflashing LSI firmware to the card? I read on Dell's spec

 sheets that the card runs an LSISAS2008 chip, so chances are that

 standard LSI firmware will work on it. I can send you all the 
 required

 bits to do the reflash, if you like.

 I got Dell Perc H310 controller for do-it-yourself experiments, I 
 tried to run it on non-Dell PC platforms like Asus P5Q and Foxconn G31MX.
 Without success.

 I will appreciate very much any hint how to get LSI firmware and 
 reflash Dell H310.
 
 
 I've successfully crossflashed Dell H200 cards with this method

PERC H200 are well behaved cards that are easy to reflash and work well (even 
in JBOD mode) on Illumos - they are essentially a LSI SAS 9211. If you can get 
them, they're one heck of a reliable beast, and cheap too!

Do you know if the HBAs in HP controllers be swapped out with any well

I know you didn't ask me, but I can tell you my experience: it depends
on what you mean by warranty. If you mean as in warranty on sales of
goods (as mandated by law), then no, sticking a different HBA in your
servers does not void your warranty (unless this is expressly labeled on
the product - manufacturers typically also put protective labels on
screws then).

When it comes to support services, though, such as phone support and
firmware updates, then yes, using a third-party HBA can make these
difficult and/or impossible. HP storage enclosure and drive firmware,
for example, can only be flashed through an HP-branded SmartArray card.

Depending on what software you are running on the machines it can make
no difference at all, or a lot of difference. For instance, if you're
running proprietary storage controller software on the server (think
something like NexentaStor, but from the HW vendor), then your custom
HBA might simply be flat out unsupported and the only response you'll
get from the vendor support team is stick the card we shipped it with
back in. OTOH if you're running something not HW vendor-specific (like
the aforementioned NexentaStor, or any other Illumos variant), and the
HW vendor at least gives lip service to supporting your platform (always
tell the support folk you're running Solaris), then chances are that
your support contract will be just as valid as before. I've had drives
fail on Dell machines and each time support was happy when I just told
them drive dead, running Solaris, here's the log output, send a new one
please.

This has been covered here, but it works. I typically use LSI-9211 and
9205 controller in G6 and G7 ProLiant systems for ZFS use. I usually
bypass the onboard controller. I don't use the HP expander card since the
LSI cards provide enough ports. That expander card is good for ZFS, though.

[zfs-discuss] pool metadata has duplicate children

2013-01-08 Thread John Giannandrea

I seem to have managed to end up with a pool that is confused abut its children 
disks.  The pool is faulted with corrupt metadata:

  pool: d
 state: FAULTED
status: The pool metadata is corrupted and the pool cannot be opened.
action: Destroy and re-create the pool from
a backup source.
   see: http://illumos.org/msg/ZFS-8000-72
  scan: none requested
config:

NAME STATE READ WRITE CKSUM
dFAULTED  0 0 1
  raidz1-0   FAULTED  0 0 6
da1  ONLINE   0 0 0
3419704811362497180  OFFLINE  0 0 0  was /dev/da2
da3  ONLINE   0 0 0
da4  ONLINE   0 0 0
da5  ONLINE   0 0 0

But if I look at the labels on all the online disks I see this:

# zdb -ul /dev/da1 | egrep '(children|path)'
children[0]:
path: '/dev/da1'
children[1]:
path: '/dev/da2'
children[2]:
path: '/dev/da2'
children[3]:
path: '/dev/da3'
children[4]:
path: '/dev/da4'
...

But the offline disk (da2) shows the older correct label:

children[0]:
path: '/dev/da1'
children[1]:
path: '/dev/da2'
children[2]:
path: '/dev/da3'
children[3]:
path: '/dev/da4'
children[4]:
path: '/dev/da5'

zpool import -F doesnt help because none of the labels on the unfaulted disks 
seem to have the right label.  And unless I can import the pool I cant replace 
the bad drive.

Also zpool seems to really not want to import a raidz1 pool with one faulted 
drive even though that should be readable.  I have read about the undocumented 
-V option but dont know if that would help.

I got into this state when i noticed the pool was DEGRADED and was trying to 
replace the bad disk.   I am debugging it under FreeBSD 9.1 

Suggestions of things to try welcome, Im more interested in learning what went 
wrong than restoring the pool.  I dont think I should have been able to go from 
one offline drive to a unrecoverable pool this easily.

That method that was linked seemed very specific to Dell servers; from my
experience with reflashing various LSI cards, can't I just USB boot to a
FreeDOS environment in any system, and then run sasflash/sas2flsh with the
appropriate IT-mode firmware?

Seems like the M1015 has spiked in price again on eBay (US) whilst the H200

 The D2600 and D2700 enclosures are fully supported as Nexenta JBODs. I run

Yes, I worked on the field qualifications for these… very nice JBODs :-)

 I *could* use an HP-branded LSI controller (SC08Ge), but I prefer the higher 
 performance of the LSI 9211 and 9205e HBA's.

Many of the big-box vendors have to deal with Windows as the target OS. Until 
Server 2012,
the use of JBODs with lots of disks was challenging for Windows. Hence, they 
offer few
options for the folks who want JBOD control.

 I recently posted on Server Fault with the Nexenta console representation of 
 the HP D2700 JBOD. It's already integrated with NexentaStor.

 Good call Saso.  Sigh... I guess I wait to hear from HP on supported IT mode 
 HBAs in their D2000s or other jbods.

  Richard,
 
  Do you know if the HBAs in HP controllers be swapped out with any well
  characterized (by nexenta) HBAs like the 9211-8e or do they require a 
  specific
  'controller HBA' like the SC-08Ge?  IE, does it void the warranty if you 
  open up
  the controller and stick a third party card in there?  Did you ever try to
  'bypass' the controllers at all and just plug into an expander?  I prefer HP
  hardware also but the controller is getting in the way.
 
  Ill be asking HP the same questions in the next few weeks with any luck but 
  your
  opinion and experiences are on another level compared to HPs pre-sales
  department... not that theyre bad but in this realm youre the man :)
 
 I know you didn't ask me, but I can tell you my experience: it depends
 on what you mean by warranty. If you mean as in warranty on sales of
 goods (as mandated by law), then no, sticking a different HBA in your
 servers does not void your warranty (unless this is expressly labeled on
 the product - manufacturers typically also put protective labels on
 screws then).
 
 When it comes to support services, though, such as phone support and
 firmware updates, then yes, using a third-party HBA can make these
 difficult and/or impossible. HP storage enclosure and drive firmware,
 for example, can only be flashed through an HP-branded SmartArray card.
 
 Depending on what software you are running on the machines it can make
 no difference at all, or a lot of difference. For instance, if you're
 running proprietary storage controller software on the server (think
 something like NexentaStor, but from the HW vendor), then your custom
 HBA might simply be flat out unsupported and the only response you'll
 get from the vendor support team is stick the card we shipped it with
 back in. OTOH if you're running something not HW vendor-specific (like
 the aforementioned NexentaStor, or any other Illumos variant), and the
 HW vendor at least gives lip service to supporting your platform (always
 tell the support folk you're running Solaris), then chances are that
 your support contract will be just as valid as before. I've had drives
 fail on Dell machines and each time support was happy when I just told
 them drive dead, running Solaris, here's the log output, send a new one
 please.
 
 Cheers,

 Saso
