Configuring RAID 1 for Sunfire V440

We have got 4 internal hard disks in Sunfire V440, Trying to get RAID 1 on these using 'raidctl'

We have done mirroring for c1t0d0&c1t1d0 but when I add the next array :
raidctl -c c1t2d0 c1t3d0 , it is not allowing : Too many arrays.

Is there any way to get RAID 1 on these with internal RAID controller of Sunfire V440?

Thanks,
Vasanth.

With the V440's SCSI controller, you cannot have more than two disks in a single RAID 1 volume. However, you say that you are using
Solaris 10 1/06. If you upgrade to the latest update, instead of using the hardware RAID 0, you can specify a ZFS volume and do just
as well or better. I don't know exactly what you are trying to accomplish, so I can't help you with the configuration directly, but in general
ZFS is the way to go once you are running Solaris 10.

I want to mirror c1t0d0&c1t1d0 and c1t2d0&c1t3d0,
ZFS is new to me..let me know if we can achieve this on Sunfire V440.

Thanks,

Sorry, I am still not sure what you want to do.

Do you want to have two separate volumes, each with two mirrored disks?
Or do you want a single large volume, made up of two mirrored sets, each
mirror with two disks?

The former you can do with raidctl, the latter will require ZFS. However, in
your position, I would use ZFS to create the former as well. ZFS is very simple to
use.

I want to have two separate volmes, how do I do with raidctl..?
Also with ZFS?
