Re: 12H AutoRaid
I am using 12H auto in production. No, there is no way to turn off RAID. The RAID will be either 0+1 or 5.

Re: 12H AutoRaid
You have absolutely no control over the physical placement of the data as fas as assigning a given LUN to a certain group of disks.

Re: 12H AutoRaid
I faced this issue little while ago when we needed more space and no redundancy of data! We were using RAID-1 (mirroring) and the best way we could use that converting all to RAID-5. We got around 85% of the disk space available for use instead of 50%. You should take a full backup of the data before you do this and then reconfigure it from scratch.
We didn't try, but if you want you can consider doing a RAID-0 (striping) on disks and set different LUNs and see the difference.

Re: 12H AutoRaid
You can however, take out the disks from their enclosures and disk bays and reseat them in a JBOD disk enclosure and disk bay, but the autoraid controllers themselves cannot be programmed to do anything but raid.

Re: 12H AutoRaid
I am piggy-backing off this thread...
2 Nodes connecting to 2 Controllers on the 12H.
I've read that only 1 controller is ever "really" active at 1 time. You can not benefit from the both X and Y Controllers simutaneously (i.e. No load balancing of throughput). I have also read many threads to the contrary of this. Help on this one...
I am experiencing performance issues and I believe I have an issue with the AUTORAID...
Controller X=1
Controller Y=0
All my LV's are going through the Y Controller but Y is NOT the Primary. Arraydsp -c arrayname shows Y as false for primary. X is the primary.
I want to do an arraymgr -c Y to set Controller Y as the primary. Will this work?
