Install the OST Plug-in for Solaris (SPARC 64‑bit and x86 64-bit)

If older OST plug-ins are already installed, existing files can be replaced with newer files.

Note: If you are using the 2.9.1 plug-in or later, you must use Solaris 10 2009 or later. For the Solaris 10 SPARC plug-in, make sure that the host is running Solaris 10 update 7 (2009) or later.

64-bit Solaris SPARC Plug-in Special Instructions

For the 64-bit Solaris SPARC plug-in, the 64-bit gcc3 run-time libraries must be installed before installing the OST plug-in. Solaris 10 includes the gcc3 libraries, but you must create a soft link for the OST plug-in to locate them.

To create a soft link to the gcc3 libraries:

Create the directory where the plug-in expects to locate the gcc3 libraries:

mkdir –p /opt/csw/gcc3/lib/64

Verify that the installed gcc3 libraries are (ELF) 64-bit:

file /usr/sfw/lib/sparcv9/libgcc_s.so.1

You should see “ELF 64-bit” or “64-bit” in the output.

Create a soft link between the plug-in directory and the gcc3 libraries:

ln –s /usr/sfw/lib/sparcv9/libgcc_s.so.1 /opt/csw/gcc3/lib/64/libgcc_s.so.1

Install the OST Plug-in

To install the plug-in:

Stop the NetBackup processes.
Create a temporary directory, such as /usr/tmp/qtmplugins.
Move to the temporary directory created in step 2. In this example it is /usr/tmp/qtmplugins
Untar the files using /bin/tar xvf QuantumOSTPluginsolaris_x86.64.tar
Move the plug-in using:

mv libstspiQuantum.so /usr/openv/lib/ost-plugins/

mv libstspiQuantumMT.so /usr/openv/lib/ost-plugins/

Move the configuration file using
/bin/mkdir -p /usr/Quantum; /bin/mv QuantumPlugin.conf /usr/Quantum
Certificate files for encryption must be installed when any method of encryption is used. Move the certificate files using the following commands:

Note: It is recommended that custom certificate files be installed to provide maximum encryption security. Use of the default certificate files provided by Quantum is not recommended.

/bin/mv cacert.pem /usr/Quantum

/bin/mv cert.pem /usr/Quantum

/bin/mv key.pem /usr/Quantum

Note: The certificate files should be the same as the certificate files installed on the DXi using the Configuration > System > Security > Data Encryption (DXi Software 3.1.0 or above) or Configuration > OST > Accent (DXi Software 3.0.x or below) page. If there are existing certificate files under the /usr/Quantum/ directory, retain a copy of them for future use.

Create a script in /etc/init.d called tcp_options and add the following lines to it (different for Solaris 10 and Solaris 11):

For Solaris 10, use the following script:

#!/bin/sh
# adjust the TCP buffer size so 'setsockopt(...)' from the plug-in
# works properly
/usr/sbin/ndd -set /dev/tcp tcp_max_buf 8388608
# These are the values that we used for Solaris 10 tcp options to get
# maximum performance. Your environment may need different tcp
# options in order to obtain maximum performance. Please consult your
# Solaris 10 administrator manual about how to set these options for
# your environment.
/usr/sbin/ndd -set /dev/tcp tcp_xmit_hiwat 4194304
/usr/sbin/ndd -set /dev/tcp tcp_recv_hiwat 4194304
/usr/sbin/ndd -set /dev/tcp tcp_wscale_always 1
/usr/sbin/ndd -set /dev/tcp tcp_tstamp_if_wscale 1

For Solaris 11, use the following script:

#!/bin/sh
# adjust the TCP buffer size so 'setsockopt(...)' from the plug-in
# works properly
/usr/sbin/ipadm set-prop -p max_buf=8388608 tcp
# These are the values that we used for Solaris 11 tcp options to get
# maximum performance. Your environment may need different tcp
# options in order to obtain maximum performance. Please consult your
# Solaris 11 administrator manual about how to set these options for
# your environment.
/usr/sbin/ipadm set-prop -p send_buf =1048576 tcp
/usr/sbin/ipadm set-prop -p recv _buf =1048576 tcp
/usr/sbin/ipadm set-prop -p _wscale_always=1 tcp
/usr/sbin/ipadm set-prop -p _tstamp_if_wscale=1 tcp

Ensure that your script is executable:

chmod a+x /etc/init.d/tcp_options

Link the startup script from the appropriate directory for your run level so the settings are persistent across reboots. In this case we used:

ln -s /etc/init.d/tcp_options /etc/rc3.d/S20tcp_options

Reboot your system.
After the reboot, check that the TCP settings are persistent For example, for checking tcp_max_buf you would type ndd /dev/tcp tcp_max_buf
(Optional) Delete the temporary directory created in step 2. In this example it is rm -rf /usr/tmp/qtmplugins
Restart the NBU processes to initiate backups and restores.
