NetBackup PBX does not automatically start upon reboot

Problem

After upgrading Linux CentOS 7.2 server, Private Branch Exchange (PBX) does not start automatically.

Error Message

# cat /var/log/messages | grep -i pbx
Apr 25 14:16:11 xxxxxxx systemd-sysv-generator[2784]: stat() failed on /etc/rc.d/init.d/vxpbx_exchanged: No such file or directory
Apr 25 14:19:30 xxxxxx pbx_exchange: Mgr_SOCK_Acceptor::shared_open, IPV6_V6ONLY socket option could not be set
 

Cause

Known Issue with Redhat 7.2 and SLES 12 SP1

The problem discussed in this document was a known systemctl defect in many Linux distributions around the release time of RHEL 7.2 and SLES 12 SP1. The use of a symlink in /etc/init.d should now work on modern Linux releases.

REDHAT
systemctl can't read symlinks to SysVinit service scripts in /etc/init.d after upgrading to RHEL 7.2's systemd-219-19.el7

Solution / Workaround

The default install path for PBX is /opt/VRTSpbx. If /opt is a separate filesystem or located on a different volume from root ( / ),  systemctl is unable to locate the target script to start PBX. 

Prior to applying the workaround, test the status of the PBX Service with systemctl to show the current state and confirm the issue exists.

# systemctl status vxpbx_exchanged.service

1.  Change to the boot volume which shows the startup location for vxpbvx_exchanged:
# cd /etc/init.d
# ls -l

lrwxrwxrwx  1 root root    32 Nov 28 08:50 vxpbx_exchanged -> /opt/VRTSpbx/bin/vxpbx_exchanged

2.  Remove the symbolic link for vxpbx_exchanged:
# rm vxpbx_exchanged

3.  Copy the start up file to /etc/init.d rather than using a link.
# cp /opt/VRTSpbx/bin/vxpbx_exchanged ./vxpbx_exchanged

# ls -l

-r-xr-x---  1 root root 11008 May  1 14:07 vxpbx_exchanged

4.  Reboot the system.  After reboot check that  vxpbx_exchanged and NetBackup services have started (see example outputs below):
# systemctl status vxpbx_exchanged
This output should show active (running) for PBX.


After workaround applied:

[root@chsxbkpsys014 ~]# systemctl status vxpbx_exchanged
