You can probably run "devfsadm -Cv" in order to clean up the device
names and find any drives which may have new names.
The trailing "d0" is from the Solaris specifications of designating a
hard drive. Hard drive names are written as "cXtXdX", which X replaced
by numbers (0-9 or hex). The lowercase letters are short for
Controller, Tray and Drive (or Disk?), respectively. Before the ZFS
days the names was usually followed by either "pX" or "sX" designating
the partition or slice number, but when ZFS is using an entire drive,
it is left out of the listing.
