migration (OVMM).

-L option is deprecated.-L option is used to create legacy packages
-C option is added to convert the package created using
the HP Integrity VM Serviceguard toolkit (old package) to
the package that uses the SG IVS toolkit (new package).
-C option is not available.
The SG IVS toolkit files and the HP Integrity VM Serviceguard toolkit are installed at different
locations and can coexist. They can be individually upgraded without impacting the other. Also,
the packages created using these toolkits, for two different VMs, can coexist and continue to use
their respective files and commands.
IMPORTANT: HP recommends not to use the hpvmsg_move and hpvmsg_package commands
with new package (package created using the SG IVS toolkit) and cmmovevpkg and
cmdeployvpkg commands with old package (package created using the HP Integrity VM toolkit).
NOTE:
• If you use the cmmovevpkg command with the old package, the Online VM migration succeeds
but the package must be re-enabled manually on the target node (that is the node specified
with the -h or -n option). The cmmovevpkg command displays the following error:
ERROR (cmmovevpkg): Unable to start package <package_name>
• If you use the hpvmsg_move command with the new package, the hpvmsg_move command
might fail on execution.
• Both the monitoring scripts, vswitchmon and vswitchmgr, provided by the HP Integrity
VM toolkit and SG IVS toolkit respectively, to manage the vswitch continues to monitor the
vswitch. If there is a LAN switchover, one of the scripts reconfigures the vswitch and the
other script logs the following warning in a syslog. The script that logs the warning message,
accepts the configuration done by the other script.
WARNING! IP Address mis-match : <ip-address> found on interface <from_lan_id> expected
<to_lan_id>
HP recommends that you convert the old package to the new package.
For more information on converting an old package to a new package, see “Converting packages”
