I have inherited an iSCSI configuration that was set as Read10/Write10. That would be okay, but the need right now is to expand the existing volumes using space from an additional disk array that has been joined to the existing array group.
That has been done. I have also expanded the volumes. I was hoping to convert the disks to GPT but interestingly I think I am running into this error. https://blogs.technet.microsoft.com/askcore/2010/02/18/understanding-the-2-tb-limit-in-windows-storage/
I have done some preliminary Googleing but have not come across a definitive answer on if there is a way to convert Read10/Write10 to Read16/Write16 without data loss or needing to restore from a backup. If there is, does anyone know the process to make that change with an iSCSI target running Windows Server 2012 R2 and Dell Equallogic PS6100 disk array?
