Console

Revisar si ctioa0 "is up and running"
( PVM's and VNC 's)
Check out ctioa0 
Revisar si ctioa8 "is up and running"
(PVM's and VNC's)
Check out ctioa8


To check VNC's, the commands and results should look like the following...

  • ON ctioa0

mosaic@ctioa0% ps aux | grep vnc

mosaic 406 0.0 0.8 2244 2984 ? S Apr 14 85:57 Xvnc :9 -desktop X -http
mosaic 408 0.0 0.0 36 0 ? IW Apr 14 0:00 /bin/sh /arc/mosaic/.vnc
mosaic 11581 0.0 0.1 56 232 pb S 11:33 0:00 grep vnc
  • ON ctioa8

mosaic@ctioa8% ps aux | grep vnc

mosaic 6281 0.0 0.1 4304 2720 pts/0 S 10:49 0:01 Xvnc :9 -desktop
mosaic 6541 0.8 0.2 6124 4568 pts/0 S 11:00 0:11 Xvnc :8 -desktop
mosaic 7465 0.0 0.0 1728 592 pts/7 S 11:23 0:00 grep vnc

 

To check that PVM is working and correctly configured on both machines

  • ON ctioa0

mosaic@ctioa0% pvm
pvmd already running.
pvm> conf
2 hosts, 2 data formats

HOST DTID ARCH SPEED
ctioa0 40000 SUN4 1000
ctioa8 c0000 LINUX 1000

pvm> quit

pvmd still running.

  • ON ctioa8

mosaic@ctioa8% pvm
pvmd already running.
pvm> conf
2 hosts, 2 data formats

HOST DTID ARCH SPEED
ctioa0 40000 SUN4 1000
ctioa8 c0000 LINUX 1000

pvm> quit

pvmd still running.


If EITHER does not look like this, it is best to simply start from the beginning. 
This involves killing the pvm processes on BOTH ctioa0 and ctioa8 and then
restarting them.  To do this, follow the instructions on restarting the pvm.
