As of SFRAC/SFCFS 4.1MP1 Veritas will not support CFS in local zones.
However if NAS/NFS is available you could try the following:
The following sequence, "hack", might help: 1. Mount the zoneroot
directories, 2. mount the NFS directories, 3. Start the local zone,
4. start the application.
This sequence should be in 1 or more service groups depending on
parallel usage.
hares -add GroupName_MNT_NFS_Mount_Point1 Mount ZServiceGroup
hares -modify GroupName_MNT_NFS_Mount_Point1 Critical 0
hares -modify GroupName_MNT_NFS_Mount_Point1 ResourceOwner FOO_GROUP
hares -modify GroupName_MNT_NFS_Mount_Point1 MountPoint “/zone/jbos1/
root/jbos”
hares -modify GroupName_MNT_NFS_Mount_Point1 BlockDevice “nfsserver:/
share_
hares -modify GroupName_MNT_NFS_Mount_Point1 FSType nfs
hares -modify GroupName_MNT_NFS_Mount_Point1 Enabled 1
hares -online GroupName_MNT_NFS_Mount_Point1 -sys startup_system
hares -add GroupName_MNT_NFS_Mount_Point2 Mount ZServiceGroup
hares -modify GroupName_MNT_NFS_Mount_Point2 Critical 0
hares -modify GroupName_MNT_NFS_Mount_Point2 ResourceOwner FOO_GROUP
hares -modify GroupName_MNT_NFS_Mount_Point2 MountPoint “/zone/jbos2/
root/jbos”
hares -modify GroupName_MNT_NFS_Mount_Point2 BlockDevice “nfsserver:/
share_
hares -modify GroupName_MNT_NFS_Mount_Point2 FSType nfs
hares -modify GroupName_MNT_NFS_Mount_Point2 Enabled 1
hares -online GroupName_MNT_NFS_Mount_Point2 -sys startup_system
Create the local zones resources, then, just as with the VxDG and
VxFS for the local zone,
have the NFS part mounted before starting the local zone and it's
applications.
zone1 requires GroupName_MNT_NFS_Mount_Point1
zone2 requires GroupName_MNT_NFS_Mount_Point2
app_jbos1 requires zone1
app_jbos2 requires zone2
In a nut shell, the NFS directory will just "show up" under each
local zones path. Make sure to create the /zone/jbos[1-2]/root/jbos
directory ;)
Hope this helps.. it's pre-coffee for me, so feel free to let me know
something is unclear.

Dear all,
I have an ISV who are proposing to have this scheme :
a. hardware are 2 nodes of Sun Fire V490
b. running Veritas Cluster, the data services is Oracle RAC, run
on both
nodes inside global zone, VxVM with CVM feature is used.
c. 2 instances of JBOSS apps running on each node, total 4
instances.
These instances will be run under 4 Container Manager. CPU and memory
usage will be managed.
The challenge is, those 4 instances of JBOSS apps inside the non-
global
zones, need to have a *read and write* to the same data location
in the
disk. Using NFS server managed by the Veritas Cluster will not work
since the non-global zones cannot mount NFS share from the global
zones.
In that case, the ISV is asking me whether if cluster file system
produced by CVM is able to be imported to the non-global zones
using lofs.
Anybody ever tried to match up the VxVM with CVM to the non-global
zones
like this?
Many thanks in advance,
Dedhi
