Looking at upgrading the Os from SLES to RHEL per blade, have a H/W RAID active on the BL. Looking at two options
- disk swap ( replace both disk with preloaded RHEL in our lab and install at customer site)
- RAID split
I was made aware that disk swap would not work if preloaded in our lab due to H/W RAID and that RAID split no real CLI available would have to obtain S/W. I was wondering if anyone has had field experience with either approach?
