CentOS 5.2 x86 and x64 are now supported as a client in NetBackup 6.5.2. This document covers a few known issues when using Centos 5.2 as a client with NetBackup 6.5.2.

Solution



Issue 1
In the default CentOS 5.2 installation, SELinux may prevent /usr/openv/netbackup/bin/bpcd from loading /usr/openv/lib/libnbmangle.so.  

This can result in the client reporting a Status 24 (socket read error) and/or the following message(s):
bpcd: error while loading shared libraries: /usr/openv/lib/libnbmangle.so: cannot restore segment prot after reloc: Permission denied

SELinux is preventing /usr/openv/netbackup/bin/bpcd from loading /usr/openv/lib/libnbmangle.so which requires text relocation.

In order to start bpcd and address this, perform the following steps:

1)  Edit /etc/selinux/config. Modify "SELINUX=enabled" to "SELINUX=disabled".

2)  Run following commands as root to enabled proper access to the necessary libraries:
   chcon -t textrel_shlib_t /usr/openv/lib/libnbmangle.so
   chcon -t textrel_shlib_t /usr/openv/lib/libvxPBXCommon.so
   chcon -t textrel_shlib_t /usr/openv/lib/libvxPBX.so
   chcon -t textrel_shlib_t /usr/openv/lib/libvxPBXVxSS.so
   chcon -t textrel_shlib_t /usr/openv/lib/libvxVxSSIOP.so
   chcon -t textrel_shlib_t /usr/openv/lib/libnbservice.so

3)  Restart the system and client operations should be restored.


Issue 2
The Java NB Console may fail to launch with error "java.lang.UnsatisfiedLinkError: /usr/openv/java/jre/lib/i386/libawt.so: libXp.so .6: cannot open shared object file: No such file or directory".        

LibXp.so.6 may not be installed by default.  If not present, the NetBackup Console will fail to launch. Either xorg-x11-deprecated-libs-6.8.1-12.i386.rpm or libXp-1.0.0-11.fc9.i386.rpm is needed before NBU is installed on this platform.  Both of these packages contain the library of LibXp.so.6.

The rpm command can be used to install the needed libraries:

rpm -i libXp-1.0.0-8.1.el5.i386.rpm



Issue 3
The rsh-server package may not be installed by default.  If not, Rsh-server must be installed separately. Rsh is the default method utilized for NetBackup for remote client installation.
If a remote install is attempted and rsh is not installed, the following messages will be seen:

<client_name> ...
Client <client_name> -- Linux hardware running RedHat2.6
Installing NetBackup software on <client_name>
<client_name>: Connection refused
Client <client_name> is not responding.
<client_name> install failed


The rpm command can be used to install the needed libraries:

rpm -i rsh-server-0.17-38.el5.i386.rpm
