Hi,

 

I purchaged 2 Toshiba MG08 enterprise capacity drives (14TB, model MG08ACA14TE (SATA).  1 is used as Parity the other as data disk (which replaces an older disk) in the Array.  The prep went fine (pre-cleared) no issues. 

I tried to follow the @spaceinvaders tutorial for Shrinking the array to the letter, which is ok, until the point where I had to create a new config. 
To remeber which disk is in which slot, and which disk is the parity drive I made a picture as was also advised in the tutorial.

When creating the new config I was confused when I saw the 2 Toshiba drives have the same serial number, as this is shown in the selector, I cannot tell which disk is the Parity and which is the Data disk.  No issue for now, as both drives where new. But certainly a potential problem in the future.

 

I checked the disk identity and I noticed that the "LU WWN device id"  are different for both drives, however this is not shown in the selector when creating a new config.

How should I select the proper parity disk in the future and tell both drives apart?

Is it an idea to use the LU WWN device id field instead of the serial number in the drive selector, or am I doing something wrong?

I run Unraid 6.10.2. 

 

Regards, Richard

Are you sure? Toshiba drives can have the same serial ending, but there are differences in the middle, or just post the diagnostics.

Oh, my god, you are right, it is a very small difference which I have overlooked completely.
