The SG IVS toolkit is a new product that inherits the functionality from the HP Integrity VM Serviceguard toolkit.

This section identifies the differences between HP Integrity VM Serviceguard toolkit and SG IVS toolkit.

HP Integrity VM Serviceguard toolkit

SG IVS Toolkit

It is part of HP Integrity VM bundle of B.04.30 and earlier versions.

It supports the legacy and modular style packaging of VM. It does not provide any module (ADF file).

It provides the hpvmsg_move command for Online VM migration (OVMM).

It provides the hpvmsg_package command to manage the VM package.

-Loption is used to create legacy packages -Coption is not available.

It is a new product from HP and must be installed separately.

It supports only modular style packaging.

It provides one module of toolkit-with-toolkit specific attributes.

It provides the cmmovevpkg command for Online VM migration (OVMM).

It provides the cmdeployvpkg command to manage the VM package.

-Loption is deprecated.

-Coption is used to perform an online conversion of the package that is created using HP Integrity VM Serviceguard toolkit to the package that uses SG IVS toolkit module.

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 -hor -noption). 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).
