PBX not responding after installation of a Master 7.7.1 on RedHat 7.2

I have installed a master / media with NetBackup 7.7.1 on a  HP/Proliant Gen9 + RedHat 7.2 platform.

Installation seems OK and there is no error messages in the installation log.

However, console do not start and command such as "nbemmcmd" do not respond.

In the trace, There is a lot of PBX access error, and If I look to "netstat", I do not see PBX port.

I partially corrected the problem by installing the rpm xinetd: pbx starts but does not respond.

I have several question about this problem :

  1. = Is xinetd mandatory on a master NetBackup
  2. = Is there other communication packages and options which are mandatory on a RedHat master server (there is nothing about this in the NetBackup documentation)
  3. = I have installed xinetd after NetBackup...
  4. = Is it possible that the PBX does not work well because xinetd.conf was not configured during installation of NetBackup

thank you in advance for your help

Re: PBX not responding after installation of a Master 7.7.1 on RedHat 7.2

1: no xinetd is not mandatory

2: no

3: Netbackup does not use tcp wrappers

4: no

To verify is PBX is started run command :  /usr/openv/netbackup/bin/bpps -x

Output :

You MUST ensure name resolution work correctly, both forward (name to IP)  and reverse (IP to name).  Proper name resolution is one of the corner stones in Netbackup.

Re: PBX not responding after installation of a Master 7.7.1 on RedHat 7.2

Check PBX is up as Nicolai suggest. I had two new redhat boxes with 7.7.1 on them have issues with PBX not running. I just started the process manually and it worked (still need to check if it survives reboots).

Re: PBX not responding after installation of a Master 7.7.1 on RedHat 7.2

For xinetd, I have a message of support that says the opposite :

The xinetd package is mandatory for a NetBackup server.

 

I do not know if xinetd is used by PBX, but I feel that when I add xinetd, communications via vnetd start to work.

Xinetd was madatory for NBU

Xinetd was madatory for NBU 6.5 and lower. From 7.X both BPCD and VNETD are standalone processes no longer spawned by xinetd.

PBX is started by /etc/init.d/vxpbx_exchanged and not xinetd.

This is my xinetd directory from a NBU 7.7 servers:

No netbackup related services.

Re: PBX not responding after installation of a Master 7.7.1 on RedHat 7.2

Thank you Nicolai...
That is true, I can start NetBackup without xinetd...

However, as Riaan write, PBX does not start automaticaly...
 and when I start it manualy "service vxpbx_exchanged start", I must also restart all the services because nbemm is missing if I just start pbx !

Does anyone known if there is a known issue for NetBackup 7.7.1 and RedHat 7.2 which explain this behaviour  ?

Furthermore, I need to increase "sysctl.conf > fs.max-file" to be able to launch the GUI... but there is no recommandations about this system parameter in the NetBackup documentation !

 

PBX must be started first,

PBX must be started first, then Netbackup. But PBX and Netbackup are two diffrent application, thus having diffrent startup programs.

As I recall RH 7 uses systemd insted of the old Sys V5 init.

Systemd enabled service dependecies :

What is starting PBX and Netbackup today - init or systemd ?

Re: PBX not responding after installation of a Master 7.7.1 on RedHat 7.2

This is my understanding.

NetBackup and PBX install their start up scripts to /etc/init.d/ on Red Hat.

In Red Hat 7.2, they got rid of the /etc/init.d/ in favor of systemd. If you want NetBackup and PBX to start automatically, you'll have to create the systemd scripts/links yourself.

`netbackup start` and `bp.start_all` do not start pbx, you have to use `/opt/VRTSpbx/bin/vxpbx_exchanged start`

Re: PBX not responding after installation of a Master 7.7.1 on RedHat 7.2

But why would NetBackup start up after reboot and not PBX? If they're both in /etc/init.d/. Can you verify if the NetBackup install has placed something in systemd to start up?

What was the fix?

Re: PBX not responding after installation of a Master 7.7.1 on RedHat 7.2

Thank you... I will check this afternoon if there is something in systemd start up (I have no access to the system this morning).

I saw that the PBX launch had been installed in /etc/init.d/, but if it is not activated by RedHat, it's useless.

If PBX is not started at boot, I think it is a mistake in the installation of NetBackup, as RehHat 7.2 is supported.

Re: PBX not responding after installation of a Master 7.7.1 on RedHat 7.2

I have joined the result of some systemctl and chkconfig  commands.

For netbackup service, the "init.d" scripts to start and stop are registered.

For vxpbx_exchanged service, there is nothing ?

Time to log a Support call with Veritas?
