Network Management

hi

i am not able to connect to airwave using https or http. the server is running and it is sending alert message. but i am not able to connect to the interface. any help on this will be appreciated.

can you SSH as root to the server?  Issue the command "daemons" There should be a long list.  Try restarting them with the command "rd"

Though restarting daemons is like hammering your way through the problem.  If you want to debug and find out the cause, it'd be worth opening a case with support.  Any crashes in the apache logs (/var/log/httpd/error_log or access_log)?

[root@bhusd mercury]# daemons ?
  PID  PPID  PGID %CPU %MEM   RSS     ELAPSED CMD

i dont see a long list just the above

What is the output of # df -h

i guess the server is out of disk space

[root@bhusd mercury]# df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/mapper/VolGroup00-LogVol00
                       65G   14G   48G  23% /
tmpfs                 3.8G     0  3.8G   0% /dev/shm
/dev/sda1              97M   36M   57M  39% /boot

have enough disk space

Did you try 'restart daemons' ('rd' command) already?  If not, go ahead and do so and open a support case to see if they can help find the root cause.

i did and below is the output

 and also i am able to connect to the interface .. thanks a lot for the help...and how do i enable autoboot...i restarted the server before running rd.. but the server is not doing autoboot. it stops in the boot prompt then i need to press enter to boot..please help me on this too.

It would seem that none of the other daemons are currently running on your server.  Check to see if the disk drive of the AMP is full:

# df -h

If it's not, then doing the 'rd' that Seth suggested could possibly get you back up and running.  But the fact that apache/pound are not visible explains why the UI was unreachable.  There may be better clues to the outtage in /var/log/low_level_service_watcher or service_watcher logs.
