Hi,

the file is introduced on 11.16 and you need to re-create it if it is not exist...

# touch /etc/cmcluster/cmknowcmds
# chmod 400 /etc/cmcluster/cmknowcmds
# chown bin:bin /etc/cmcluster/cmknowcmds

GOOD LUCK!!

thanks for commands

but i confused
why does this file(a cmknowncmds file) be used in service guard

what's role?

[Peter Godron]

Hi,
all the ServiceGuard documentation states is that this file is an internal file. Maybe for planned enhancements?? The new version apparently has a comment in the file warning against removal.

Could you please complete the thread by awarding points to helpful answers and summarising the solution for you.
This will help resolution of similar problems in the future.

As I put in the parallel thread

Hi

I presume you are on 11.16

You need to install patch
PHSS_32731 or later.

Patch Name: PHSS_35302

Patch Description: s700_800 11.11 Serviceguard A.11.16.00


The patch refers to the problem in its doc:

5. A new internal file called cmknowncmds now exists in
in /etc/cmcluster. T he file was originally shipped as
an empty file giving the customer no idea the
importance of the file. If this file is accidentally
deleted the cluster can fail to start and messages
are logged in syslog that say: "Error opening
/etc/cmcluster/cmknowncmds

This is an internal file and should not be edited or deleted
