Table 16 Types of Changes to Packages (continued)
Required Package StateChange to the Package
Both packages can be either running or halted.Add or delete a configured
dependency
Special rules apply to packages in maintenance mode; see “Dependency Rules
for a Package in Maintenance Mode or Partial-Startup Maintenance Mode ”
(page 294).
For dependency purposes, a package being reconfigured is considered to be
UP. This means that if pkgA depends on pkgB, and pkgA is down and pkgB is
being reconfigured, pkgA will run if it becomes eligible to do so, even if pkgB's
reconfiguration is not yet complete.
HP recommends that you separate package dependency changes from changes
that affect resources and services that the newly dependent package will also
depend on; reconfigure the resources and services first and apply the changes,
then configure the package dependency.
For more information see “About Package Dependencies” (page 142).
The SG-CFS-pkg package must be running, before a modular CFS package can
be started. For information on modular CFS packages, see “Creating Modular
Disk Group and Mount Point Packages” (page 210).
Add CFS packages
For legacy style packages, before you can add an SG-CFS-DG-id# disk group
package, the SG-CFS-pkg Cluster File System package must be up and running.
Before you can add an SG-MP-id# mount point package to a node, the
SG-DG-id# disk group package must be up and running on that node.
Package can be running. See “Online reconfiguration of modular CFS package
parameters” (page 215).
Change modular CFS package
parameters:
cvm_activation_mode for Disk
group packages
cfs_mount_options,
cfs_primary_policy for Mount
Point packages
ckpt_mount_options,
ckpt_primary_policy for
Checkpoint packages
Package can be running provided the status of the generic resource is not 'down'.
For information on online changes to generic resources, see “Online
Reconfiguration of Generic Resources” (page 141).
Add a generic resource of
evaluation type
during_package_start
Package can be running if the status of generic resource is 'up', else package
must be halted.
Add a generic resource of
evaluation type
before_package_start
Package can be running.Remove a generic resource
Package can be running if the status of generic resource is 'up'.Change the
generic_resource_evaluation_type
Not allowed if changing the generic_resource_evaluation_type causes the package
to fail.
For information on online changes to generic resources, see “Online
Reconfiguration of Generic Resources” (page 141).
Package can be running for resources of evaluation type before_package_start
or during_package_start provided the new up criteria does not cause the resource
status to evaluate to 'down'.
Change the
generic_resource_up_criteria
Not allowed if changing the generic_resource_up_criteria causes the package to
fail.
For information on online changes to generic resources, see “Online
Reconfiguration of Generic Resources” (page 141).
