This is a different scenario than what this thread addresses, but to answer your question: Yes, you can remove one 1TB SAS disk and replace it with another SAS disk to rebuild.
We are upgrading the hard drives in our Dell Poweredge T110 outfitted with a PERC-H200A and two 1TB SATA drives in mirrored RAID. We run the Dell T110 version of ESXi 5.1 and a single Windows Server Essentials 2012 VM. We wanted to double our Hard Drive capacity and the Dell Support sold us 2x 342-1020 (2TB 7.2K NL SAS,6G,3.5,CB,CK) Drives. What is the easiest way to replace the existing SATA drives in the RAID with these new drives in the same configuration and EXSi / VM / OS? Does the RAID Controller handle creating the new RAID and copying the data over somehow?Do I add the New Drives in a second DiskVolume and Build a Second (SAS) RAID and then somehow clone or copy the original (SATA) RAID over to the New one then switch the boot device to the new (SAS) RAID? Thank you,Dan
