Figure 37 Legacy Style of Packaging
Figure 38 illustrates an example in which all the disk group and mount point packages used by
Application 1 are consolidated into a single modular package as compared to four separate
packages in the legacy style of packaging.

Use Case 2: Migration of two different applications using checkpoint and snapshot packages
Figure 39 illustrates a cluster with two applications independent of each other. The mount points,
SG-CFS-MP-1 and SG-CFS-MP-2, are created on the cvm_dg1 and cvm_dg2 disk groups with two
logical volumes, lvol1 and lvol2, respectively. The cluster file systems /mnt1 and /mnt2 are mounted
on the mount points. Note that the storage check point package, SG-CFS-CK-1, and the snapshot
package SG-CFS-SN-1 have a dependency on the mount point package.
