Expand HDD raid 5

[mkhls]

Hi,

I have 5 X 600GB Raid 5 + Spare at HPE DL380
4 HDD Running 1 HDD Spare.

I have new 3 HDD to expand raid 5.
If additional new 3 HDD will result loss of existing data on raid 5?

TQ

Hello,

Array expansion should not result in data loss. however it is recommend to have a valid backup before expansion for worst case scenario.

To expand the array you may refer to the below document & Smart Storage Administrator User guide

Please note that the additional drives must have a capacity no less than that of the smallest drive in the array.

Thanks,
