Hello Hugh,

I am going to send you a private message and if you can provide me with the serial# for the controllers of your Compellent I can use secure console to look into the error.  Here is the link to enable secure console if you need it. https://www.dell.com/support/article/us/en/04/how12050/dell-storage-sc-how-to-send-supportassist-and-enable-secure-console?lang=en

Please let us know if you have any other questions.

Sam,

We don't have support on the system, hence why I'm posting in the forum.

Regards,
Hugh McDaid

Per a very old guide: Foreign Managed: A disk that is recognized by this Storage Center system but not managed by it. A Foreign Managed disk could have been managed previously by another Storage Center system or another manufacturer. When the disk is assigned, it becomes Managed.

I am not certain this is true any longer. 

After I "managed" the disk. It appears to be stuck in the "Transitioning" control type, and never becomes available for user data. If I try and unmanage the disk, it gets stuck doing that too. And the only option is to revert back to managed.

Andrew,

I have not been able to clear the state on this drive. I have swapped out other drives since this one, and it has successfully removed the foreign disk state. I think maybe I added the first drive incorrectly, and now it's stuck in that state. I have not tried replacing it with a difference drive, but maybe that will fix it.

Regards,

Hugh

Hi McDaid,

I too have a disk stuck in the transitioning stage on my old Compellent.  Do you recall how you resolved your issue?  I did not have the same original issue, but am at the same point as you.

I have a compellant sc5020 and the drives apart from the header show foreign. Does anyone know the command to revert these back to normal.

Help!! 

I really am not fussed about the data its only backup storage i just need the cli commands to revert the disks back

Thanks Josh for your help so far

Steven

Hi,

 Do you have a validated backup of the data? Since this is a potential data loss situation it is recommended that you call phone support.  

https://dell.to/3yYZIhW Page 67 I would start with a restart, I don’t see any CLI commands that allow clearing the foreign state. You may also want to physically reseat a drive and see if it picks it back up.
