Re: Adding additional Hard Disk

Hello,

1) Add two disks to array

2) Change raid level to 5

3) Add last disk to array.

4) Expand logical drive if needed or create new.

Re: Adding additional Hard Disk

Not clear what's the final result you want to achieve...

5 disks in RAID 5?
2 disks in RAID 1 and 3 in RAID 5?
Expand the existing logical drive at the hardware level or create a new one and add it to the existing one using OS tools?

All that is possible...

Check the ACU user guide to see how to expand arrays and extend logical units:

I need to enlarge the logical drive.
I want to add 3 more disks in raid 5.
so to conclude:
I want to have:
1)2 disk in raid 1 ( that is what I currently have )
2) add 3 disks in raid 5
3) in the end to enlarge the disk space and maintain the current disk structure.

Re: Adding additional Hard Disk

Then you can follow my advice using the Array Configuration Utility

Re: Adding additional Hard Disk

this is applied to Linux as well?
since I have Linux os installed.

Re: Adding additional Hard Disk

Aviram, if you create another RAID and another logical unit with the 3 disks in RAID 5, you'll need to use operating system tools to join that space to the filesystem. Then it's a question for Linux forums.

Create a new RAID and logical unit in ACU is the easy part.
