Cisco DCNM server unresponsive

You’re running a DCNM virtual appliance and when you’re trying to log on, it looks like the appliance’s webserver is no longer active.

Connect to the Linux prompt of the appliance and do the following:

Stop DCNM services:

/usr/local/cisco/dcm/dcnm/bin/stopLANSANServer.sh

Open the psql prompt:

/usr/local/cisco/dcm/db/bin/psql dcmdb

log on with root password (user root is assumed)

Type the command:

VACUUM FULL ANALYZE VERBOSE;

This will produce tons of output, but just let it run and eventually it all ends and you just need to start the DCNM services again.

When done, quit the psql prompt:

dcmdb=> \q

Start DCNM services:

/usr/local/cisco/dcm/dcnm/bin/startLANSANServer.sh

  1. Hi Rob,

    Do you know what information gets purged ? Specific time frame ? I would hate to purge all of my performance stats.

    Thank you
