Hello ItsFudd

When you are trying to add a new drive to your Preservation Capacity do you have your DDP that you created selected or no? Also are you following the steps in the admin guide on page 101? http://downloads.dell.com/Manuals/common/md32xx_md36xx_administrator%20guide_en%20us.pdf

Please let us know if you have any other questions.

Thanks for the guide, I have followed the guide and it was similar to what I was doing before but when I want to allocate 3 and press OK everything seems fine but when I go in to check only one is allocated.

I don't receive any errors when pressing OK but my changes just don't apply. I am not sure what I am doing wrong. Is there another place where I need to save and confirm changes?

Thanks

Michael

Hello Michael,

No there is not any other place to set Preservation Capacity. You set Preservation Capacity when you create your disk pool & can be changed as outlined in the link I sent you. Have you tried to logout of MDSM & log back in to see if the changes appear? Also what version of firmware are you running on your MD3200i?

Please let us know if you have any other questions.

The current firmware on the enclosures are 1.05 and I have disconnected from the manager and reconnected and there is no visual glitch. is it worth completely removing the Disk pool and re creating it?

I have deleted the virtual disk and tried that and still fails, I have also deleted and recreated the disk pool to attempt to allow more disk prevention to be allocated. Is there a limit to the amount of disk prevention depending on the disks as I can lower it to 0 and increase up to one but not any higher so I feel as if there is a cap which is preventing from increase my disk prevention capacity.

Also I have a different disk pool and I can increase the disk prevention capacity to 3 even though it is currently set to 2 so I don't think there is a firmware issue.

Hello Michael,

I did some checking and there is a limit to the # of drives that you can add to your Preservation Capacity. Since you only have 11 drives in the pool the max is 1 drive for Preservation Capacity. The amount of preservation capacity to be utilized by a Dynamic Disk Pool is fixed depending on the number of drives that were created within the pool. That is why you only have the option of using 1 disk.

Please let us know if you have any other questions.

Hello Michael,

What is the version of firmware on your MD3200i? The firmware version that you provided was for your MD12xx. Also just so I make sure that I am understand you correctly you have a DDP that has 11 disk in?

Please let us know if you have any other questions.

The version of DM is 11.25 and that is correct I have 11 Disks in the newly created disk pool is that what is restricting me on adding more prevention space?

Hello Michael,

Here is the link to the PDF that has the info listed on page 9. https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&uact=8&ved=0ahUKEwiPv-S00b3UAhVLN48KHUO7BtcQFggmMAA&url=http%3A%2F%2Fi.dell.com%2Fsites%2Fdoccontent%2Fshared-content%2Fdata-sheets%2Fen%2FDocuments%2FPowerVault-MD3-Dynamic-Disk-Pools-Technical-Report.pdf&usg=AFQjCNGtzl__ce9BEDI_Qq5dG0I32DFVdA

Please let us know if you have any other questions.

That is great, but i am still not sure how many disks I need for a prevention capacity of 3 as I still don't understand how the ratio works.
