I just installed some new SATA drives in my 2010 MacPro and when I formatted them, it created Logical Volume Groups for each drive and now I have a drive named "Untitled" There does not appear to be any way to rename this drive, only the Logical Partition. How do I rename the Volume Group to something more descriptive? Thanks in advance.
Mac Pro, OS X Yosemite (10.10.4), 2010 6 Core
I also seem to have lost the ability to set up a RAID array with these new drives. What gives?
Open the OS X Terminal Utility (in Applications > Utilities) and run the following command:
diskutil cs listWhen you do this, a tree-like output will show (expand the window to see it all, if needed). Then notice the name of the Logical Volume Group, which should be the "Name: groupname" entry under the bar of equals signs that underscore the words "Logical Volume Group: UUID_NUMBER".
Yours is likely called "Untitled" so I will use that in this following command which is the one to use for renaming the drive:
diskutil cs renameLVG Untitled NewNameIf you want a space in the name (such as "My LVG Name") then use double-quotes around the name.
Thanks. That worked well in renaming the Logical Volume Group!
Any suggestions on how to get back the ability to set up a RAID array now that the option is missing on the two new drives and I only have First Aid, Erase and Restore?
Cheers
Booting from the 10.6 original installation disk, I was able to reformat the drives properly and now have full functionality returned, including access to RAID capabilities. Cumbersome, but a definite usable work around to this issue of 10.10 not fully recognizing drives greater than 2TB.
