[SUMMARY] Problem mounting RAID volume at boot on V880z

I would like to publicly acknowledge those who can't seem
to properly configure their auto-responders:

Original question follows.

First of all, those warnings about failed forcemod can be ignored,
that's just Solaris Volume Manager trying to load the kitchen sink.
You can comment out entries in /etc/system to avoid the warnings.
Sorry about the RTFM question.

   You can find the explanation in metaroot's manpage

   WARNING: forceload of misc/md_hotspares failed might  appear
     during boot if root is on a metadevice and no hot spares are
     specified. This can be eliminated by defining an  empty  hot
     spare pool.

     WARNING: forceload of misc/md_trans failed might  appear  if
     no trans devices have been configured.

     WARNING: forceload of misc/md_raid failed might appear if no
     RAID5 devices have been configured.


My problems with my volume not having a device, and hence not being
mountable, on boot is because it is set up as a "disk set" using
-s with metainit. Eugene Schmidt nailed this:

  The problem is that you have created the volumes in set (-s) option. 
  Metaset require RPC calls. In the bootup sequence, this is after the 
  mount in /etc/rc2.d.

  I suggest destroying all volumes and metadb's, then restart - without
  creating metasets.

  1) create "metadb -f -a cXtYdNsZ", etc till all metadbs are created ( -f
     only with first)
  2) metainit d1 ...... (no -s) etc

I had already made sure that the rpc.meta* entries in /etc/inetd.conf
were not disabled, as suggested by several people.

Some more helpful info from Eric van de Meerakker:

  You always need the system to explicitly take ownership of a diskset
  at boot-up. Non-diskset devices will be automatically mounted and can be
  specified as usual in /etv/vfstab, diskset devices cannot be mounted
  directly from /etc/vfstab.
  
Other general suggestions were to check if the state database replicas
are set up properly (metadb -i) as well as the stripe (metaset).
