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 that you do not use the hpvmsg_move and hpvmsg_package
commands with the package created using the SG IVS toolkit. Similarly do not use cmmovevpkg
and cmdeployvpkg commands with package created using the HP Integrity VM toolkit.
NOTE:
• If you use the cmmovevpkg command with the package created using the HP Integrity VM
toolkit, the Online VM migration succeeds, but you must manually re-enable the package 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 package created using the SG IVS toolkit,
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 appropriate warning in the /var/adm/syslog/syslog.log. The
script that logs the warning message, accepts the configuration done by the other script.
HP recommends that you convert the package created using the HP Integrity VM toolkit to the
package using the SG IVS toolkit.
For more information on converting the package created using the HP Integrity VM toolkit to the
package using the SG IVS toolkit, see “Converting packages” (page 18).
