If you attempt to use the Disk Management screen on the web interface to add a disk to a RAID array, you may receive a "No Access" error message. If you observe the array after this error, you will notice the drive has not been added.


You cannot use the web interface to add disks to the RAID array.


The error is encountered any time the GUI is used to add an array member.


All other disk management interfaces work properly. iControl or TMSH can be used to work around this GUI issue. For example, addition of disk HD2 in TMSH would use the command 'tmsh modify sys raid array MD1 add HD2'
