How to expand Solaris Volume Manager filesystem which is exported to zones from Global Zone

Ok, it's been long that no updates on blog... Anyways, Today I'm having some good information on - "How to expand Solaris Volume Manager (Metadevice) filesystem which is exported to zones from Global Zone"

I've a uniqe system which is having little diffrent configuration than other systems. I've SPARC-Enterprise M4000 system and having 2 zones running on it. Here is the zone configuration example for one of them.

# zonecfg -z zone1 info
zonename: zone1
zonepath: /zone1/zonepath
brand: native
autoboot: true
bootargs:
pool: oracpu_pool
limitpriv: default,dtrace_proc,dtrace_user
scheduling-class:
ip-type: shared
[cpu-shares: 32]
fs:
dir: /oracle
special: /dev/md/dsk/d56
raw: /dev/md/rdsk/d56
type: ufs
options: []
fs:
dir: /oradata1
special: /dev/md/dsk/d59
raw: /dev/md/rdsk/d59
type: ufs
options: []
fs:
dir: /oradata2
special: /dev/md/dsk/d62
raw: /dev/md/rdsk/d62
type: ufs
options: []
fs:
dir: /oradata3
special: /dev/md/dsk/d63
raw: /dev/md/rdsk/d63
type: ufs
options: []
[...]


Ok, So here you can see that I've metadevices which are exported to the zone from the global zone. I need to expand one of the filesystem say /oaradata1 by XXG so how am I going to perform this? Take a look at below procedure to understand on how we can do it.

global:/
# zonecfg -z zone1 info fs dir=/oradata1
fs:
dir: /oradata1
special: /dev/md/dsk/d59
raw: /dev/md/rdsk/d59
type: ufs
options: []
global:/
# metattach d59 Storage_LUN_ID 

global:/
# growfs -M /zone1/zonepath/root/oradata1 /dev/md/rdsk/d59


This all operation needs to be performed from global zone.
