these are the steps you need to follw.

Scan new disks (ioscan + insf)
Create new vgs & lvs
Export vg to map file
Import vg in all failover nodes
Deactivate vg (vgchange â a n vgname)
Make vg cluster aware (vgchange â c y vgname )
Active vg exclusively (vgchange â a e vgname )
Mount new new lvs manually with mount command
Take copy of /etc/cmcluster/pkg/pkg.cntl file
Edit /etc/cmcluster/pkg/pkg.cntl & add new vg, lv details
Copy pkg control files to all failover nodes

> I need to add one new lvol in one package

No problem.

- Create new lvol
- Update vgconfiguration in standby node (vgexport, vgimport)
- Modifiy control script in both nodes
- Mount FS in prymary node

Following steps need to perform on your active node (where currently pkg is running).
-----------------------------------------
Check whether do you have enough space in VG or not, if not please add more disk in the VG.
Create new LV.
Create mount point.
Mount the file system.
Update pkg control script.
Create the map file for VG
Vgexport -p -s -m
