In HP ProLiant ML-370 G6 (Windows Server 2008 R2). I have three HDD 147 GB each in my existing array RAID 5. Now I want to extend the existing array by adding two more 147 GB each extra HDD but I don't want to lose my current data or go through the process of setting everything up again from scratch. Can any one help me?

  • My math says you have a max of 300gb of data, and a 2tb hdd is $54 approx. Backup and go, problem solved?? Why are you wasting time with 147gb hdd? A single SSD will probably beat the performance of all of them. A 1tb ssd will offer more capacity than the drives you have plus the drives you are adding. 3 sdd sata = 1500mb/s your array is left in the dust. Plus you will save a lot of electricity. – cybernard Apr 18 '17 at 13:40

You can extend like that / migrate only if you have BBWC or FBWC. Otherwise, those options are not available in the Array Configuration Utility.

  • Is there any other tool available like Hp array configuration utility, to expand the current array ? @Overmind – Faisal Apr 18 '17 at 12:39
  • Unfortunately the tools are quite exclusive. – Overmind Apr 19 '17 at 5:28
