'zpool attach' or 'zpool replace' Return "EFI labeled devices are not supported on root pools."

(Doc ID 1494415.1)

Last updated on JULY 29, 2016

Applies to:

Solaris Operating System - Version 10 3/05 and later
Information in this document applies to any platform.


The following 'zpool attach' or 'zpool replace' command results in an semi-ambiguous message

The message could be interpreted as 'c0t5000CCA02A1BFC9Cd0' already having an EFI label which is not supported for root pools.  This is not the case even if the disk did have a valid EFI label.


The change is trying to add a whole disk to an rpool using the 'zpool attach' or 'zpool add' command
