Dual scsi on V480 with no Veritas using Solstice
 

Has anyone managed to set up SCSI load balancing or at least failover to a dual channel scsi raid unit?

I can see both controllers, but can't figure out how to set up the meta device to see it as a single controller with failover/balancing. In Veritas this is simple, but Solstice is just plain confusing.

equip:

Sunfire V480
dual channel Sun scsi U320 controller
Winchester Flashdisk RAID

The CLI interface of DiskSuite is probably less confusing than the GUI. In short the procedure is something like:
- Slice the first disk like you normally would using format. Remember that you need extra small slices somewhere to keep your meta DB.
- Slice the second disk disk to match.
- Init the DBs with meta init.
- Create the mirrors or what ever like with the metainit command.
- Attach the devices.
- Edit /etc/vfstab to point to the correct devices.

This like gives the basics for mirroring the root disk:

I've already got sds mirroring the root drives. My question is on a high performance raid array. What is the best way to interface with the dual controller, use just one? Or is there a way to balence between the 2, like with veritas. Right now I'm setting up a transmeta db for journalling, but can only hit one of the controllers.

Cheers for the input.

How did you configure the volumes in the RAID array? Are they distributed across drives on both controllers? Unfortunately DiskSuite doesn't have all of the functionality the Veritas software, but it is moving in the right direction. You could do something like put a file system on each controller then mirror them, then using the logging option in /etc/vfstab. At least then all copied of the file system will have logging. Also, do you have multiple copies of the metadb?

Did WinSys happen to supply an management software or drivers with the hardware to enable more complex configurations?
