raid controller on rx6600

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 ?

Re: raid controller on rx6600

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.

Re: raid controller on rx6600

you have to check with rgmanager command

or you can control in EFI mode.

Re: raid controller on rx6600

does anyone have the syntax for the rgmanager, when i key in rgmanager i get a not found, i searched the entire system for
rgmanager and got no hits ???

Re: raid controller on rx6600

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.

Re: raid controller on rx6600

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:

disk 1 0/4/1/0.0.0.0.0 sdisk CLAIMED DEVICE HP
IR Volume
/dev/dsk/c1t0d0 /dev/rdsk/c1t0d0
/dev/dsk/c1t0d0s1 /dev/rdsk/c1t0d0s1
/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 ----------
LUN dsf SAS Address Enclosure Bay Size(MB)

/dev/rdsk/c2t0d0 0x5000c50001234567 1 7 70007
/dev/rdsk/c2t1d0 0x5000c50001234567 1 8 70007

ioscan:

disk 3 0/1/1/0.0.0.0.0 sdisk CLAIMED DEVICE HP
DH072ABAA6
/dev/dsk/c2t0d0 /dev/rdsk/c2t0d0
/dev/dsk/c2t0d0s1 /dev/rdsk/c2t0d0s1
/dev/dsk/c2t0d0s2 /dev/rdsk/c2t0d0s2
/dev/dsk/c2t0d0s3 /dev/rdsk/c2t0d0s3
...




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

Hope this helps!

Re: raid controller on rx6600

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

Re: raid controller on rx6600

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

Please post your

# ioscan -fn

Hope this helps!

Re: raid controller on rx6600

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

Re: raid controller on rx6600

If this command

sautil /dev/ciss1

returns with information, you have a smartarray controller.

try

# saconfig /dev/ciss1

too.

Hope this helps!
