SC4020 delete removed drives
Is there a way to delete removed / missing drives?
Unit is out of warranty. I am trying to set it up in my lab... not production. I have most of the original drives and it can boot fully. My issue is that it originally had an SSD tier (I don't have any of the SSD drives). While I have deleted all of the volumes and servers the SSD disk cannot seem to be removed because "at least one user allocation present". I think it's because the original config had data progression configured and it the drives are still in that disk folder.
All I am trying to do is delete the drives and the tier from the config, so I can use the array.
Also, the existing tier 3 drives are showing 65% allocated even though I deleted all the volumes and emptied the recycle bin. I have tried to "release" some of these drives but they just say "releasing" and it's been over 24 hours.
Any assistance is appreciated.

For those looking for info like this... I figured out how to clear the existing config.
NOTE you must have an active license file tied to the array you are working on. If you don't have this file DO NOT follow this set of steps, you will make your array useless. If you are the owner of the array, even if it's not under warranty, you can ask Dell to generate a license file.
Here is what I did:
Connect using the console cable to the slave unit (usually the bottom controller)
Let unit boot
Log in using Admin account
run the following commands
>Shellaccess developer
>cs purge all
>disk global clobberall
>-reset (note the command has a - in front of the reset)
Connect using the console cable to the Main unit (usually the Top controller)
Log in using Admin account
run the following commands
>Shellaccess developer
>cs purge all
>disk global clobberall
>-reset (note the command has a - in front of the reset)
Disregard any error messages about "downed disks". For me at least, this worked when I rebooted the controllers. The config, which is stored on multiple physical drives in the array were cleared.
When it reboots the config will be gone. The controller IP address for the Main Controller previously set will be still In place (if you need to clear this there are other commands to run first before rebooting). You will need to use the Storage Manager EXE program (this cannot be done from the web interface) to rebuild the config (although it can be done from the CLI).
The Admin password will be reset to "mmm".
Good luck.

Hi,
Are you able to turn off the data progression? Page 135 https://dell.to/3wPLApS
Let us know if you have any additional questions.

Hello,
Thank you for the response. Page 135 of the doc you referenced doesn't seem to talk about "Data Progression", rather it talks about snapshot profiles.
I have paused "data reduction" and SnapShot Creation and I tried to disable all the raid options on the Tier 1 disk settings, hoping to allow the deletion of the missing SSD drives. It will not allow me to completely disable all the Tier 1 options.
