Replace disk to increase capacity of RAID 6

[FedericoCoppola]

Hi All,
I need to increase capacity of a server.
The server model is ProLiant DL360 Gen10 with just four slot for hard drive.
At the moment all slots are busy with 900GB  drive using RAID 6.

The RAID controller is "HPE Smart Array P408i-a SR Gen10".
Is it possible to replace one disk at a time to increase the capacity of the raid?
Can this controller manage this stuff?

After that, is possible expand RAID volume?

Thanks so much!

Yes, this is possible.

Thanks so much for your reply.

How can I know if my RAID controller can do it?

Thanks

Yes this can be done using the server and controller you have listed.  You will need to weigh the time and effort of expanding the array vs yank and rebuild from scratch.

To expand the array, you will need to replace each drive individually and wait for it to finish rebuildong each drvie in teh current array configuration. Once this is complete, you then exapnd the array in SSA to reclaim the new extra unused space. Once this is complete you then use tools in the OS to expand tthe OS partitions, or create new partitions with the unused space.

Anytime your going to change or modify a controller or disks, make sure you have a valid data backup

Hi @Jimmy Vance,

Thanks for your confirm about this task.
I can not rebuild the raid from zero due to it is production server.
 I will keep all steps that you suggested!

Thanks
