I just installed 151a7 on a new system with disks connected directly to an LSI-9207-8i HBA.   The installer correctly located the attached disks, built the rpool and boots fine:

<pre>
root at hcp-dr-zfs01:~# zpool status
  pool: rpool
 state: ONLINE
  scan: none requested
config:

        NAME                       STATE     READ WRITE CKSUM
        rpool                      ONLINE       0     0     0
          c4t5001517972EE63FBd0s0  ONLINE       0     0     0

errors: No known data errors
</pre>

When I attempted to add a second disk to mirror the rpool the zpool command reports: EFI labeled devices are not supported on root pools.

<pre>
root at hcp-dr-zfs01:~# prtvtoc /dev/rdsk/c4t5001517972EE63FBd0s2 | fmthard -s - /dev/rdsk/c4t5001517972EE64A2d0s2
fmthard: Partition 2 specifies the full disk and is not equal
full size of disk.  The full disk capacity is 156273152 sectors.
fmthard:  New volume table of contents now in place.
root at hcp-dr-zfs01:~# zpool attach -f rpool c4t5001517972EE63FBd0s0 c4t5001517972EE64A2d0
cannot label 'c4t5001517972EE64A2d0': EFI labeled devices are not supported on root pools.
</pre>

Seems the installer is supoorting EFI labled disks for rpool but the zpool command is not.
