Managing HP Serviceguard A.12.00.00 for Linux, June 2014

NOTE: To verify whether the failure of PKG1 affects any other packages:

#cmsimulatecl --session cmviewcl

• To recover from the last package failure:

#cmsimulatecl --session test_cluster recover -p PKG1

Failure and recovery of an interface

• To simulate an interface failure on a node:

#cmsimulatecl --session test_cluster fail -n test1 -i eth0

NOTE: To verify whether the packages running on test1 failed over or not, and where the

packages are currently running:

#cmsimulatecl --session test_cluster cmviewcl

• To recover the last interface failure on a node:

#cmsimulatecl --session test_cluster recover -n test1 -i eth0

NOTE: Assume that you have failed node1 and node2. You can only recover the failure from

node2, but cannot recover from multiple sequential failures. Also, you can only recover from the

last failure.
