I have one IBM DS5020 storage, all the slots are full, and we have big array configured with raid10
we wanted to add some more disk space into the existing RAID10
i have some questions :
1) i need to buy an EXP520 expansion unit to connect to the DS5020, do i have to rebuild the existing RAID10 or not ? i dont want to, because it is in use with all the data on it.
2) if the answer to the above question is NO, how do i do it without reformating the data ?
