Single node Sun Cluster with zones

How can we add a shared zfs dataset between 2 zones on a same host. I have sun cluster 3.2 installed in a server which has 2 zones. I want to share a zfs data set between these 2 zones how can we do that ?

Just add the dataset mount directory as a lofs filesystem for both zones.

Is it possible to share a ufs file system in global zone in both the zones ?

You can indeed share ZFS, UFS or VXFS filesystems (actually directories) between zones.

But sharing that way give me another problem.I have /u01 on my global zone

Code:
/dev/dsk/c0d1s0        9.8G   6.6G   3.1G    68%    /u01

which has been lofs mounted to zone node1 and zone node2. /u01
has all the oracle stuff.And if create an rg for same db in /u01 between the 2 zones i get following error in alert log
Code:
# clrg status

=== Cluster Resource Groups ===

Group Name   Node Name              Suspended   Status
----------   ---------              ---------   ------
ora-rg       esstll020-u614:node1   No          Online
             esstll020-u614:node2   No          Offline

Code:
ORA-12012: error on auto execute of job 42567
ORA-27468: "EXFSYS.RLM$EVTCLEANUP" is locked by another process

Is it feasible to do this just for testing purpose or not.

That is a different issue. You can share a filesystem between zones but if one application place a lock on it, it will be hopefully enforced.

So i think i cannot go any further than this .. Is is possible to share file system to zone without mounting it in global zone ?
