raid controller on rx6600

Donald Thaler — Fri, 05 Dec 2008 16:50:24 GMT

For the two internal drives on my rx6600 i show an 'HP Core IO SAS Controller RAID1' on the configuration list. How can i tell if the controller supports hardware mirroring ?

AFAIK the base MPT controller that comes bundled in with the rx6600 supports hardware RAID-1 mirroring. I think you can't configure it once your OS is installed, so better do it as soon as you boot your server for the first time.

you have to check with rgmanager command

or you can control in EFI mode.

you have to check with rgmanager command

or you can control in EFI mode with ORCA.

Don,

God knows what rgmanager is - I've certainly never heard of it.

Anyway - chances are what you have is a Standard SAS HBA in your rx6600 (although some systems ship with full SAS based Smart Array cards).

The manual is here:

http://docs.hp.com/en/J6369-90071/J6369-90071.pdf

As has already been indicated, if the system isn't already HW mirrored, you will probably have to re-install to get it HW mirrored.

Use:

ioscan -fnkd sasd

To identify the controller on the system, and then:

sasmgr get_info -D /dev/sasd0

or whatever it's identified as to get some data on its current configuration.

HTH

Example for a configured hardware RAID using the default LSI chip:

# sasmgr get_info -D /dev/sasd0 -q raid

---------- LOGICAL DRIVE 5 ----------

Raid Level : RAID 1
Volume sas address : 0x9ad0b1234567
Device Special File : /dev/rdsk/c1t0d0
Raid State : DEGRADED
Raid Status Flag : ENABLED RESYNC IN PROGRESS
Raid Size : 69878
Rebuild Rate : 0.00 %
Rebuild Progress : 0.18 %

Participating Physical Drive(s) :

SAS Address Enc Bay Size(MB) Type State

0x500000e014123456 1 7 70007 PRIMARY ONLINE
0x5000c50123456789 1 8 70007 SECONDARY ONLINE

ioscan:

/dev/dsk/c1t0d0 /dev/rdsk/c1t0d0

/dev/dsk/c1t0d0s2 /dev/rdsk/c1t0d0s2
/dev/dsk/c1t0d0s3 /dev/rdsk/c1t0d0s3

...

example for "plain" disks without hardware raid:

# sasmgr get_info -D /dev/sasd0 -q raid

---------- PHYSICAL DRIVES ----------

ioscan:

/dev/dsk/c2t0d0s2 /dev/rdsk/c2t0d0s2
/dev/dsk/c2t0d0s3 /dev/rdsk/c2t0d0s3
...

Note the "HP IR Volume" for the configured RAID.

these command don't return anything..
ioscan -fnkd sasd0
sasmgr get_info -D /dev/sasd0

is it possible that i should be using something other than sasd0

Yes, it could be the upgrade - a smartarray P400.

Please post your

# ioscan -fn

update... had to use >ioscan -fnkd ciss command followed by >sautil /dev/ciss1, and this showed that there were two drives Participating in the mirroring:
Physical Disk(s)...... Ct:Enc:Bay:WWID 2I:1:8:0x500000e0173fb4d2 2I:1:7:0x500000e0173fc852

sorry 'bout dat. It was sasmanager.

If this command

sautil /dev/ciss1

returns with information, you have a smartarray controller.

try

# saconfig /dev/ciss1

too.
