This is a zinger not even IBM has not been able to answer. We have an IBM e server x345 model 8670 6cg with a server raid 6m adapter. We are also hooked up to an exp400 expansion box, It is a live system which currently contains 4 drives under RAID10, We need to grow 2 more drives into it on the fly without destroying the RAID10 or our data. Please let us know if this is possible using server raid software. Everything has been updated and we are in a windows environment. It is also possible that we will have to expand again in the future so it is imperative that we can do this without breaking RAID10 or destroying data, backups aside.
