Expand RAID 10 on PERCH730 possible?

[fiza]

I have a Dell Server with a PERC H730 controller. The Data is held on a RAID10 array comprising of 4 x 1.2TB disks. Currently running low on space on these so I want to add additional drives to expand the RAID 10 array without losing any data.

 

I have read conflicting articles on the web where some say expanding RAID 10 is not supported on the PERC series controllers without losing data and others saying it is now but wasn't previously.

 

Has anyone done this?

Same configuration as you. Have you checked the options in iDRAC? Edited November 29, 2018 by vimagoes

So you've got spare drive slots you want to use to add more 1.2tb disks to the array? Or you want to replace the existing 1.2tb disks with larger ones without losing the array?

 

The first one may be possible, the second probably not.

 

If it is supported you would have to reboot into the actual PERC BIOS to see if you get the expand option, it can not be done through the windows software.

The server was set up by an external company who are now gone. They never set up the IP for iDRAC access. I am not in a position to take the server down to set iDRAC up yet. Over the Christmas holidays maybe.

There are spare slots available.

So theoretically, yes, you can add disks to the array in pairs and expand it.
