SUNWzfsr, SUNWzfskr, and SUNWzfsu. Note that ZFS has dependencies on

ZFS uses relies on three SMF services:
1) svc:/system/filesystem/local:default
2) svc:/system/device/local:default
3) svc:/system/fmd:default
The last service maybe disabled but you lose your ability to receive FMA
events.

-l /dev/dsk/C_t_d. I''d like to know what they mean each line. I have
some idea what it means but not every line.

Take a look at chapter 1 of the Ondisk format guide (specifically pages
9-14) as they include the majority of the lines above.
