7.5.1.1 Rules for a Package in Maintenance Mode or Partial-Startup Maintenance Mode
IMPORTANT: See the latest Serviceguard release notes for important information about version
requirements for package maintenance.
• The package must have package switching disabled before you can put it in maintenance
mode.
• You can put a package in maintenance mode only on one node.
The node must be active in the cluster and must be eligible to run the package (on the
package's node_name list).
◦
◦ If the package is not running, you must specify the node name when you run cmmodpkg
(1m) to put the package in maintenance mode.
◦ If the package is running, you can put it into maintenance only on the node on which it
is running.
◦ While the package is in maintenance mode on a node, you can run the package only
on that node.
• You cannot put a package in maintenance mode, or take it out maintenance mode, if doing
so will cause another running package to halt.
• Since package failures are ignored while in maintenance mode, you can take a running
package out of maintenance mode only if the package is healthy.
Serviceguard checks the state of the package’s services and subnets to determine if the package
is healthy. If it is not, you must halt the package before taking it out of maintenance mode.
• Generic resources configured in a package must be available (status 'up') before taking the
package out of maintenance mode.
• You cannot do online configuration as described under “Reconfiguring a Package” (page 240).
• You cannot configure new dependencies involving this package; that is, you cannot make it
dependent on another package, or make another package depend on it. See also “Dependency
Rules for a Package in Maintenance Mode or Partial-Startup Maintenance Mode ” (page 223).
• You cannot use the -t option of any command that operates on a package that is in
maintenance mode; see “Previewing the Effect of Cluster Changes” (page 226) for information
about the -t option.
7.5.1.1.1 Additional Rules for Partial-Startup Maintenance Mode
• You must halt the package before taking it out of partial-startup maintenance mode.
• To run a package normally after running it in partial-startup maintenance mode, you must take
it out of maintenance mode, and then restart it.
