Migrating packages from legacy to modular style

Figure 8: Modular package configuration after migration

Troubleshooting

• If you use cmeasymigrate only to migrate or consolidate CFS MP & DG packages it will display some warning messages

telling that you have to change the dependency condition in the application packages which are dependent on

consolidated CFS packages. Display of these warnings doesn’t mean that the command has failed. For example,

consider a scenario where an application package is dependent on a CFS Mount point package which in turn depends

on a CFS Disk group package.

• If you use cmeasymigrate to consolidate the legacy mount point and disk group package into a single modular

package it will display a message as follows.

Note: Change the dependency in the following packages from the package <mp_pkg_name> to <consolidated_pkg_name>:

<application_pkg_names>

• In the same scenario as above, if you can use cmeasymigrate to migrate only the CFS legacy disk group package, it will

display a warning message as follows.

WARNING: Legacy CFS package <mp_pkg_name> is dependent on <dg_pkg_name> which is migrated to modular now

<mp_pkg_name> must also be converted to modular.

This message gets displayed because cross dependencies (legacy mount point package dependent on modular disk

group package (or) modular mount point package dependent on legacy disk group package) are not supported with

CFS packages and you have to migrate the CFS legacy mount point package also to modular.

cmeasymigrate can fail for the following reasons:

• cmeasymigrate will fail if the toolkit legacy package has any dependencies other than a Serviceguard shipped toolkit

package(s) or CFS mount point and disk group package(s).

• If a toolkit legacy package and CFS mount and disk group packages are specified on the command line then the toolkit

package must be dependent on those CFS mount point and disk group packages. Otherwise error will be thrown and

migration will not be done.

• For consolidation of multiple CFS packages, common package parameters like auto_run, node_name etc should be

same across the packages specified for consolidation.
