3PAR storage is Solaris Cluster's newest enterprise class storage partner and is now officially listed on the Solaris Cluster 3rd party storage matrix:

3PAR is a leading provider of utility storage a category of highly virtualized and dynamically tiered storage arrays. The inclusion of 3PAR support on Solaris Cluster adds another dynamic storage option for Solaris Cluster customers to deploy.

One of the common issues I face is having many pools with the same name. This happens many times I reinstall the OS for a new build of Sun Cluster software is out to test.  I use standard naming conventions and hence when I create a new pool without checking if there is already one with the same name, then I get an error on import:

bash-3.00# zpool import app
cannot import 'app': more than one matching pool
import by numeric ID instead

So how to find out which pools are available?  There are 2 way.  You can either use the ZFS manager GUI if you aren't too comfortable using the CLI or you can execute zpool import command which will list all the potential pools that can be imported:

bash-3.00# zpool import
  pool: app
    id: 17303573419851088164
 state: ONLINE
status: The pool was last accessed by another system.
action: The pool can be imported using its name or numeric identifier and
    the '-f' flag.
   see: http://www.sun.com/msg/ZFS-8000-EY
config:

    app         ONLINE
      raidz1    ONLINE
        c2t1d3  ONLINE
        c2t1d2  ONLINE

  pool: app
    id: 13179891989473835286
 state: ONLINE
status: The pool is formatted using an older on-disk version.
action: The pool can be imported using its name or numeric identifier, though
    some features will not be available without an explicit 'zpool upgrade'.
config:

    app         ONLINE
      c2t1d1    ONLINE

  pool: mysql
    id: 6396206132307901430
 state: ONLINE
status: The pool is formatted using an older on-disk version.
action: The pool can be imported using its name or numeric identifier, though
    some features will not be available without an explicit 'zpool upgrade'.
config:

    mysql       ONLINE
      c2t1d0    ONLINE

  pool: post
    id: 11620670201616239827
 state: ONLINE
status: The pool is formatted using an older on-disk version.
action: The pool can be imported using its name or numeric identifier, though
    some features will not be available without an explicit 'zpool upgrade'.
config:

    post        ONLINE
      c2t0d2    ONLINE

Now that I know the pools and their IDs,

bash-3.00# zpool import 13179891989473835286
bash-3.00# zpool destroy app

Voila!
