MC/Service Guard hangs up - HELP

Ionut Grigorescu_2 — Thu, 26 Sep 2002 07:28:02 GMT

Hi,

I have an HPUX 11.00 server with MC/SG. I have performed a
#cmhaltcl -fv
I have 3 packages: comm (communication package, omcdb - O&M package and db - database package)
After halting omcdb the system hangs up in trying to halt comm package. I cannot interrupt the process - what can I do?

look at the /etc/cmcluster/comm/comm.cntl.log (I suppose that you name thus) file in the server that owns comm package...

what says?

...it says

..HALTING PACKAGE COMPLETED but with cmviewcl I can see
STATUS - halting
STATE - halting
??

Hi,
Also see /var/adm/syslog/syslog.log
Is it due to NFS server not responding ?

I tried to telnet to a workstation with NIS to this server and I have this message NFS server not responding still trying, but in syslog on the server I have only

Whats happend if I try now to halt the db package (this supervises the ORACLE processes)? and then reboot the server?

If u try to halt the db pkg now it will also look for nfs server.
Give us some picture how is your setup? like how many nodes and which nodes runs which pkg?
after pkg halt, nfs server not responding is quite "normal".
A reboot will definately solve your problem.

Hi,
You can again add the pkg IP using cmmodnet command.
look details syntex of cmmodnet command.

Re: MC/Service Guard hangs up - HELP

Animesh Chakraborty — Thu, 26 Sep 2002 08:29:15 GMT

the syntex is
#cmmodnet -a -i 15.44.49.77 15.44.48.0
IP =15.44.49.77
subnet: 15.44.48.0

Hi,

cmmodnet should be used only on a halted packege (it says in the man page..)
I have a node which is comm server on which runs comm package and another node which is the database server on which run db and omcdb package. I decide to trust the log file who told me that comm pkg is halted and I have halted also db package with cmhaltpkg then I have performed a reboot on both servers - now I'm waiting...

Hi,

#shutdown -r -y 0 doesn't work!!
It halts at
Stop High Availability Cluster ....

I have tried also cmhaltnode ... nothing!

What can I do more?

Re: MC/Service Guard hangs up - HELP

Joaquin Gil de Vergara — Thu, 26 Sep 2002 09:17:33 GMT

is the other node running?

if it has stopped cluster services the other node can wait for it to form cluster

Re: MC/Service Guard hangs up - HELP

With cmviewcl I can see that PKG_SWITCH is disabled for all packages. Both nodes are up and running despite my cmhaltnode command. I performed also this shutdown with no success...:-(

Hi,

case closed. I have killed MC/SG's processes and then I have succsesfuly rebooted. Not so elegant but practical...
