HP XC System Software Installation Guide Version 3.2

NOTE: HP SFS, Serviceguard, and RGS have not been qualified on HP XC System Software
that is installed on Red Hat Enterprise Linux (described in Chapter 7 (page 137)). If you are
installing HP XC System Software on Red Hat Enterprise Linux, do not install these HP software
products.
3.7.7.1.1 HP StorageWorks Scalable File Share
The HP XC System Software enables Lustre
1
client services for high-performance and
high-availability file I/O. These Lustre client services require the separate installation of Lustre
client software, which is provided by the HP StorageWorks Scalable File Share (SFS) product.
You can configure HP SFS to operate with an HP XC system to provide scalable storage that is
easy to use and easy to administer.
In addition to providing scalable storage, locating the clusterwide /hptc_cluster file system
on an HP SFS server enables fail over of that file system. If you want to enable improved
availability of this file system, install the HP SFS client software now so that you can mount the
file system on the SFS server instead of installing it on a local disk.
The HP SFS client software is distributed on the HP StorageWorks Scalable File Share Client
Software CD (the SFS software is not provided on the HP XC System Software DVD). Contact
your HP representative if you do not have a copy of the HP SFS CD.
Instructions for installing HP SFS client RPMs and configuration instructions specific to HP XC
are located in the SFS documentation, specifically the SFS Client Installation and User Guide. Follow
those installation instructions to install SFS now.
The SFS documentation is available on the documentation CD that was delivered with the SFS
product. It is also available at the following website:
http://www.docs.hp.com/en/linuxhpc.html
3.7.7.1.2 HP Serviceguard
HP Serviceguard is the service availability tool recommended for use on an HP XC system.
If you intend to use Serviceguard as the availability tool, you must have in your possession the
Serviceguard license, the distribution media, and the product documentation. Use the Serviceguard
documentation to install the product now. The documentation is available from the following
website:
http://www.docs.hp.com/en/ha.html
The HP XC System Software has been tested with the following Serviceguard for Linux RPMs.
You must install the RPMs in the following order:
1. pidentd-3.0.15sg-1.rpm
2. qs-A.02.00.03-0.product.redhat.{architecture}.rpm
3. serviceguard-A.11.16.04-0.product.redhat.{architecture}.rpm
NOTE: HP recommends that you obtain the latest available release of Serviceguard for Linux
Version 11.16 and all available patches so that you install the most up-to-date version of
Serviceguard. New versions of Serviceguard Version 11.16 interoperate with HP XC Version 3.2
as expected.
The quorum server RPM, qs-A.02.00.03-0.product.redhat.{architecture}, is required
only if you plan to configure a quorum server. If your particular configuration uses lock LUNs
exclusively, you do not install the quorum server RPM.
The Serviceguard software contains two modules that are built against the kernel.
After installing the Serviceguard software, proceed to “Deciding on the Method to Achieve
Quorum for HP Serviceguard Clusters” to define and configure the method to achieve quorum.
