i have 6 disks, can i create Raid1 configuration with 3D+3P?and how much total space i get for that configuration?
fyi..i'm not in customer site right now, so..can't try it.
welcome for any solution.thanks.

Something is wrong here:

SAS3080X-HP

PN:AD348A

The first (SAS built-in controller) cannot do RAID5 - only RAID1) - the second (smartarray P400) can, but looks like you don't have it?

At least it is not connected to the disks ...

Please post an "ioscan -fn" first!

... BTW, the built-in controller can only manage 2 pairs of mirrored disks + spare - that's it. Other disks have to be managed by LVM only.

Francisco,

If this is really a P400 Smart Array (and not just a SAS HBA which can only do RAID 1), then you are using the wrong command - sasmgr is used with the SAS HBA - the command for configuring a P400 Smart Array is saconfig not sasmgr.

But the device file you are seeing (/dev/sasd0) looks like its for a SAS HBA rather than a P400. Do you get anything back from:

ioscan -kfnd ciss

That will give you the device file for the P400 (if you have one). Then use saconfig to configure - see the manual here:

http://docs.hp.com/en/J6369-90072/J6369-90072.pdf

If you do an ioscan, a smartarray controller looks like this:

ext_bus 0 0/5/0/0/0/0 ciss CLAIMED INTERFACE PCIe S
AS SmartArray P400 RAID Controller
/dev/ciss0

To get information use

# saconfig /dev/ciss0

The built-in SAS looks like this:

escsi_ctlr 0 0/1/1/0 sasd CLAIMED INTERFACE HP PCI/PCI-X SAS MPT Adapter
/dev/sasd0

Fransisco Aris — Mon, 15 Sep 2008 06:21:25 GMT

the bad is..in support matrix they don't mention which Raid level match in which OS :(

aniway...i have P400 too, yes it can do raid5. from customer side they want do raid1 with configuration 3D+3P (6 disks), possible?and how much total capacity can i get?
below my ioscan output.
thanks lot.

Do you have disks on the P400?

# saconfig /dev/ciss1

and post.

Looks like you already have what you want - a RAID1 (2 disks) + RAID5 (6 disks).

Re: rx6600 raid5 creation failed

Fransisco Aris — Mon, 15 Sep 2008 06:45:38 GMT

from controller 1 (/dev/scsi0) it's ok.
but from controller 2 (/dev/sasd0) how to configure that disk (6 new disks), for best practice and best perfomance.thanks

Re: rx6600 raid5 creation failed

Torsten. — Mon, 15 Sep 2008 06:53:14 GMT

As said before - the controllers are different. sasd0 cannot do RAID5!

Only 2 pairs of mirrored disks + spare or plain disks with LVM.

thanks Torsten and all for participating. give me more confidence. tommorow i'll update this thread.
