I also tried expanding the array and after the transformation was completed at 100 percents nothing happened, restarted the server but not the storage array and still the same, was told I need to do some command to activated it in windows since the transformation is ready as I was using the HP storage array utils in windows to this. Do I need to change it to dynamic disc since it is simple disc.
Solved! Go to Solution.

SolutionNow that you have expanded your array, you have added the new disk to the array, and your excisting Logical Drive has been destributed over 4 disks.
Now you have got some empty, unused space on your array.
You can Extend your excisting LUN or can create new LUN(s)
If you extend the LUN, windows will see it as a lager disk, and you will need to extend partition, or you can create a new parttion.
If you create new LUN(s), windows will see it as new disk(s),but windows will not see any difference, where you are now

Prakash

Re: MSA Raid 5 disk expansion
Create a logical drive using the ACU? And then see if I can use the Windows disc management in windows to extend it?
If not do I create a logical drive in Acu and try the extend again using the array utils?
Or do I convert the Basic disc to dynamic from disc management in windows and then use the acu to create a logical drive and then go back to disk management in windows and see if I can extend it since it is now dynamic disc?
Or once I convert it to dynamic disc in windows I do all this in the array utils?

Re: MSA Raid 5 disk expansion
If you want a larger disk. Then you select the Logical drive, and extend it.
From the ACU.
If you want an addtional disk, then you create a new logical drive using the ACU.
Untill you do one of the aboave, windows will see no change.
When you have got a RAID controller, windows do not see the physical disks.
Windows see the logical disks.

Re: MSA Raid 5 disk expansion
Your current RAID 5 is 558 GB, using 33 drives.
That means your data is 279Gb + 279GB = 558GB.
Which means whenever you add a disk, min 279 Gb or larger you can extend your logical drive to 279GB. And in the remaining space, you can create a new logical drive.
Here is an example:
Lets say:
You have got 1 x 100 GB disk and 2 x 150 GB disk.
You want to use this for a RAID 5.
Then you can create a RAID 5 of 200 GB.
100 GB + 100 GB of data + 100 GB of parity.
The smallest disk decides the size of your RAID
In this theory, you use 100 GB on all 3 disks. Leaving you with 2 x 50 GB unused space. You can use that for a 50 GB RAID 1 or 100 GB RAID 0.
In you case, You are for some reason limitted to 279 GB per disk.
In windows If you extend the logical drive.Windows will see it as a larger disk.
You can extend your partition, which can be a challenge, on the boot/system partition.
I will not be of much help on that part. Or would suggest you to create a new partition.

Re: MSA Raid 5 disk expansion
Do I need to convert my drive from Basic to dynamic first in the Windows disk management before I extend the logicial drive in ACU?
The drive has share data on it and no OS is installed with it.

Re: MSA Raid 5 disk expansion
You can extend the logical drive rescan device manager then check you have got a bigger drive in diskmanage
open a command window
run diskpart.
This should help you for the disk part.

Re: MSA Raid 5 disk expansion
1. Physically hot install the disk.
2. Add new disk to array, using ACU
(expand array)
3. Extend logical drive using ACU.
4. Extend windows partion using diskpart
