OK to add different manufacturer/revision physical drives to existing RAID5 array?

Hello, this may help:

Online Capacity Expansion (OCE) is a process that allows users to add storage capacity to an existing virtual disk. In most cases, this can be done without taking the system offline

Thank you, but I know how to add a disk to the array and expand the volume. What I am asking is if the different manufacturer and revision level presents any risk? They both have the same Dell P/N...

Hello yert33,

Could you post picture of the drive labels showing the Dell part number (DP/N)?

We do have same drive by different manufacturer but typically they get different part numbers.

Generally speaking if the drives are the same technology and they are the same or larger capacity you can add them in to the array. If it is larger capacity then the remainder of the drive would be unusable.

Thanks for the reply Charles R. I got the Dell P/N from plugging in the Service Tag into Dell and looking at the System Configuration. We have not modified this R720 since purchase. Here is the screen shot of that:

The new ones are the same capacity, etc and show up in OSMA as candidates for adding to the array.

Thanks, Charles. I can't pull them out the originals as they are in production and there are no spares.
