Reviewing Cluster and Package States with the cmviewcl Command
Chapter 3 81
PACKAGE STATUS STATE AUTO_RUN NODE
pkg1 up running enabled ftsys9
pkg2 up running enabled ftsys9
NODE STATUS STATE
ftsys10 up running
Both packages are now running on ftsys9 and pkg2 is enabled for
switching. Ftsys10 is running the daemon and no packages are running
on ftsys10.
Status After Halting a Node
After halting ftsys10, with the following command:
# cmhaltnode ftsys10
the output of cmviewcl is as follows on ftsys9:
CLUSTER STATUS
example up
NODE STATUS STATE
ftsys9 up running
PACKAGE STATUS STATE AUTO_RUN NODE
pkg1 up running enabled ftsys9
pkg2 up running enabled ftsys9
NODE STATUS STATE
ftsys10 down halted
This output is seen on both ftsys9 and ftsys10.
Viewing RS232 Status
If you are using a serial (RS232) line as a heartbeat connection, you will
see a list of configured RS232 device files in the output of the cmviewcl
-v command. The following shows normal running status:
CLUSTER STATUS
example up
NODE STATUS STATE
ftsys9 up running
