Upgrading to HP Serviceguard 11.17 with Cluster Volume Manager/Cluster File Systems, December 2005

Appendix A
The following slides illustrate various upgrade scenarios and the relevant storage management
options.
This is a typical pre-upgrade scenario. CVM support is provided by the VxVM-CVM-pkg SMNP, the
application package is configured with STORAGE_GROUP attributes, and the package control script
declares CVM_DG[*] and CVM_DISK_ACTIVATION variables to specify storage.
