My client has a DL380 G5 with a Smart Array P400 controller. Currently I have three RAID 1+0 arrays configured, all using SATA drives. This is a highly used server and we're starting to see drive failures. I'm recommending going to SAS drives for better performance and lifespan. The question now is how to change the drives. Can I simply replace one drive in the mirror, allow the rebuild to take place, then replace the second drive? This would be the easiest approach. If not, any recommendations on how to replace the drives without data loss? I can schedule some downtime if necessary.
Thanks,
Joe
