Solaris 11.2 dump device "kernel without ZFS metadata"

I've never seen this, is it normal for 11.2? Anyway to change it back to dumping metadata or is this simply an overly verbose message I may ignore?

Code:
kernel without ZFS metadata

Code:
:/etc# dumpadm 
Dump content      : kernel without ZFS metadata
Dump device       : /dev/dsk/c7t5000CCA025721FADd0 (dedicated)
Savecore directory: /var/crash
Savecore enabled  : yes
Save compressed   : on
/etc# dumpadm -d /dev/dsk/c7t5000CCA025721FADd0
Dump content      : kernel without ZFS metadata
Dump device       : /dev/dsk/c7t5000CCA025721FADd0 (dedicated)
Savecore directory: /var/crash
Savecore enabled  : yes
Save compressed   : on

I ran the below and feel more comfortable with the results but am still baffled why it was configured not to dump ZFS metadata with the standard command of "dumpadm -d /path/to/device"

Code:
etc# dumpadm -c all
Dump content      : all
Dump device       : /dev/dsk/c7t5000CCA025721FADd0 (dedicated)
Savecore directory: /var/crash
Savecore enabled  : yes
Save compressed   : on

To clarify, this is the output I'm trying to achieve as part of our standard server build. I've ran through the dumpadm -c switches and not been able to accomplish it.

Code:
dumpadm -d /dev/dsk/c0t5000CCA0226F19A4d0
      Dump content: kernel pages
       Dump device: /dev/dsk/c0t5000CCA0226F19A4d0 (dedicated)
Savecore directory: /var/crash
  Savecore enabled: yes
   Save compressed: on

***Update***

I believe that this is new for 11.2 behavior as a colleague who was building an identical server experienced the same output.

Please see this link at Oracle and let me know what you think. I believe that the below from the link is relevant.

Starting with the Oracle Solaris 11.2 release, dump content is organized into sections. By default, dump content includes following two sections:

Core kernel pages

ZFS metadata pages

Look at the "-c" option on the dumpadm man page.

I did, see above. Ultimately, my team lead decided that the new behavior from "dumpadm -d" is acceptable.
