This is a little risky task I want to try. I have a 4 SATA III disks RAID10 array running on LSI (former 3ware) 9750-8i controller with BBU (read and write cache enabled). In case of hardware failure I would like to move the array to older 3ware controller, model 9650SE-8LPML without BBU.
Configuration of that array is:
/c2/u0 status = OK
/c2/u0 is not rebuilding, its current state is OK
/c2/u0 is not verifying, its current state is OK
/c2/u0 is initialized.
/c2/u0 Write Cache = on
/c2/u0 Read Cache = Intelligent
/c2/u0 volume(s) = 1
/c2/u0 name = mons
/c2/u0 serial number = S1DGCBEB159EED0051BF
/c2/u0 Ignore ECC policy = off
/c2/u0 Auto Verify Policy = on
/c2/u0 Storsave Policy = balance
/c2/u0 Command Queuing Policy = on
/c2/u0 Rapid RAID Recovery setting = all
- Is this at all possible?
- Is the lack of BBU in the older controller will not cause failure?
- In such a case (no BBU), only the read and write cache stops working?
