Table 9 Differences between Legacy CFS and Modular CFS (continued)
ModularLegacy
Provides improved manageability of the package by allowing
you to edit the parameters in the package configuration file.
You must not manually edit the packages, but use the
cfs commands to edit the package. The disadvantage
Also, allows online addition, deletion, and/or modification
is that if you have multiple packages, you must edit each
of them using the commands.
of CFS parameters. See “Online reconfiguration of modular
CFS package parameters” (page 215).
The high availability cluster information displayed by the
cmviewcl command output is more compact.
When a large number of packages are configured , the
cluster information displayed by the cmviewcl
command contains too many entries.
Listed below are some of the operational differences in terms of commands used for creating or
managing legacy and modular CFS packages. For usage, syntax, and keyword descriptions, see
the respective Serviceguard man page of each command.
