HP NL40 (previously ZFS for esxi): only 2 of 6 ssd's visible in windows 2012

Hi,

Please see previous post (http://www.experts-exchange.com/Software/VMWare/Q_28347213.html) for more info.

Currently my NL40 is on latest HP Bios firmware. Now I succesfully installed Windows 2012 by setting SATA controller mode to IDE (previously it was AHCI, RAID is also an option).
I also installed the megaraid tool (http://www-947.ibm.com/support/entry/portal/docdisplay?lndocid=MIGR-5077712) which allows me to configure raid.

However, now only 2 out of 6 ssd's in sharkoon are visible in Windows. All sata drives are drives but only 2 ssd 's (60 GB OCZ's Agile 3) can be seen, the other drives: Kingston 120 GB are not visible. Probably something in BIOS, but not sure what.

Please advise. In BIOS harddiskdrives all show.

J.

How are your SSD drives connected to your Host Server?

The LSI connector, only supported 4?

So do you have 4 connected to LSI, and 2 SSDs connected to motherboard?

Motherboard BIOS should really be set to AHCI or RAID not IDE, this is for old legacy drives.

I have an LSI LSI SAS 9211-4i | LSI00190.
Sata s are connected to motherboard indeed. 1 ssd via esata (bios fix), other on motherboard but those disks it cannot see. It are only two of four connected to lsi (sharkoon), it can see.  

When on AHCI, it could see all drives but Windows couldn't install(?!)
When on IDE, it can install to the drives but it can only see 2?
Now when I switch back to AHCI ... Windows boots up ... and sees them all.

Damn, do I really need this trick to install?

You must have AHCI and all RAID disabled.  You do NOT want a megaraid controller. You want a plain, vanilla non-RAID LSI controller.   The megaRAID firmware will virtualize the I/O and not only kill performance, but defeat all the advantages of ZFS in the first place.

Your disk configuration is simply a non-starter.   Get the right controller for the job.

Oeps, not correct, it sees one disk more, 1 of 120 GB but that's it.

Okay, so you have

4 x SSDs - connected to LSI controller.

2 x SSDs - connected to Motherboard. (please note now that you have un-done the BIOS-FIX both these SSDs will only operate in legacy IDE mode, AHCI is not available, unless you have hacked your new BIOS!)

AHCI will only affect the disks connected to the motherboard.

AHCI BIOS enabled on motherboard will not alter LSI config.

Clarification, you must have AHCI on, and a non-RAID controller.  Legacy mode will kill performance also, as it restricts use of many of the low-level ATA commands that one needs for large block I/O and queued commands.

@dlethe This is a standard Windows 2012, no VMs, no ZFS!

also as the mapping of the LSI Storage BIOS is not working, it's unlikely you will be able to BOOT an OS, from any RAID configuration or disks on this controller.

So you will need to BOOT your OS from the disks attached to motherboard, and they will only be in IDE mode, because eSATA and CDROM SATA port, and restricted to IDE only. (without hacking your BIOS!)

Buy another controller if you have to, strictly for the SSDs.  Legacy mode is absolutely unacceptable or you leave a great deal of performance on the table.  Use host-based software mirroring on them.  In perfect world you'll get 2X the read performance.

Damn, do I really need this trick to install?

with you current configuration, and motherboard BIOS, yes this is what is required.

I did recommend another server, you would not have ALL this hassle with!

(PS We've already been there, and feel your pain with the Microserver!)

The config costed me quite some money. Can t switch for now.  Thanks for all the answers but what should I do then to make it work on Windows 2012? Flash the bios to hack? Then use software mirroring? No use of lsi then?

LSI and connected disks will work in Windows 2012, but you will not be able to boot from these disks.

Software Mirror in the OS on SSDs, probably will work as well as RAID (which you cannot configure!).

if you flash back - no support for Windows 2012 R2.

Please clarify. What is the conclusion then?
I do have all disks on software raid now, my only option I guess(?) so performance should not be less then hw/lsi raid?

If you are happy with the performance "leave as is".

I might consider buying another machine after all then. Esxi on it this time and ZFS for vm's and NAS functionality. The one you proposed seems interesting, but why not 64 GB instead of 32 GB (to not bump into limits a few years from now ... again). And I'd also like to built in my Shakroon with SSD's .... Now I have a mixture of ssd's, lsi, rac. Hope to recuperate at least some of it.

The server listed is entry level, not designed for Hypervisors!

If you want a large Hypervisor system, use a desktop and add 64GB of memory.

Off the record: raid created with megaraid software (windows), will it persist? Then I can use it for my zfs vm on esxi.

No it was not, unfortunately. Back to ZFS now. Flashed the bios. I've set the steps: http://homeservershow.com/hp-microserver-n40l-build-and-bios-modification.html but the 6 th disk is not visible ...

Yes, that site references my site.

Use another N40L, maybe the newer bios has changed something, and this server will no longer correctly, apply this hack.

Did you factory reset the CMOS.

Never mind, I only need 5 disks, 2 for OS, 3 for cache & logs. Thanks anyway.

And a black screen after reboot. This never ends.
Sounds familiar though, this blinking cursor. Had it before but no clue what it was.

And here it is: http://www.experts-exchange.com/Software/VMWare/Q_27976696.html

but I'm installing from USB from external usb drive.

Though I yanked the cd drive out, that's true. I'll try to reinstall and remove cd-rom instead of usb of cd drive.

No luck this time. Reinstalled Nexenta with cd usb drive. After succesfull install I rebooted, ejected the cd when on boot screen ... blinking cursor. Nothing happens.

No lights are blinking on the sharkoon. I removed all but the two laptop disks on which I installed the Nexenta OS. No lights blink, it's just not looking at the ssd's in the sharkoon.
