6.0 HP X9000 File Serving Software Installation (TA768-96041, October 2011)

5 Adding Linux X9000 clients
Linux X9000 clients run applications that use the file system. The clients can read, write, and delete
files by sending requests to File Serving Nodes. This chapter describes how to install, configure,
and register the clients.
Prerequisites for installing the Linux X9000 client
Before installing the client software, do the following:
• Install a supported version of the operating system, accepting all packages. Do not add or
delete packages from the package list.
• Disable SELinux. X9000 Software services will not start if SELinux is enabled.
• Disable DHCP. X9000 Software requires static IP addresses to communicate.
• Start the rpcidmap.d daemon.
• Use the hostname command to verify that the host name returned is the expected name and
that it can be resolved by its name and IP address on all File Serving Nodes and the client
itself.
• Ensure that the machine clock is synchronized (for example, via Network Time Protocol).
• If an IBRIX user and group exists on the machine, delete them. X9000 Software requires
exclusive use of the IBRIX user and group.
• In the operating system, set up the network interface that will be used for cluster network
communications. Set up only one cluster interface.
NOTE: By default, communication flows through the cluster network. If that network is not
available to the client, you will need to prefer another communication route for the client. See
“Preferring a network interface for a Linux X9000 client” (page 48).
• Verify that the client machine can communicate with the active management console and file
serving nodes. X9000 Software requires successful ping -s 16000 communications between
all machines.
Installation procedure
To install the client software, complete the following steps:
1. Expand the distribution tarball, or mount the distribution DVD in a directory of your choice.
This creates an ibrix subdirectory containing the installer program. For example, if you
expand the tarball in /root, the installer is in /root/ibrix.
2. Change to the installer directory. To install into the default home directory (/usr/local/
ibrix), enter the following command, where CLUSTER_INTERFACENAME specifies the
interface to be used for cluster communication, and CLUSTER_IP_ADDRESS is either the
name or IP address of your management console machine:
./ibrixinit -tc -C CLUSTER_INTERFACENAME -i CLUSTER_NAME/VIF_IP
For example:
./ibrixinit -tc -C eth4 -i 192.168.49.54
To install into a different directory, use the following command:
./ibrixinit -tc -C CLUSTER_INTERFACENAME -i CLUSTER_NAME/VIF_IP -P PATHNAME
3. Verify that the X9000 client is operational. The following command reports whether X9000
services are running:
/etc/init.d/ibrix_client status
