that the file system is mounted:

Mount Point Packages for Snapshot Images using Modular Style Packages
The following example illustrates how to create a snapshot image. Consider that cvm_dg3 is the
disk group configured into a package dg2pkg.
1. Create local storage on which to place the snapshot:
vxdg init cvm_dg3 c4t1d0
vxassist -g cvm_dg3 make vol1 100m
vxvol -g cvm_dg3 startall
2. Create a package configuration file for the snapshot image:
cmmakepkg -m sg/cfs_all snap1.ascii
Package template is created. This file must be edited before it can be used.
3. Edit the following package parameters in the snap1.ascii package configuration file:
package_name snap1
node_name node1
snapshot_mount_point /snap1
snapshot_name cvm_dg3_node1/lvol3
snapshot_cfs_mount_point /mnt2
snapshot_mount_options "node1=ro"
NOTE: By default, the package parameters are commented out. You must uncomment them
and specify the values.
snapshot_mount_point name of the mount point for the snapshot
snapshot_name Diskgroups/Logical volume pair used to store the
snapshot image
snapshot_cfs_mount_point unique name for CFS mount point; supports nested
mount points
snapshot_mount_options the CFS mount options for the snapshot. For detailed
information about the mount options, see the
mount_vxfs (1m) manpage.
4. Configure the appropriate dependencies (if any) of the snapshot image:
