Setup guide

3 If error messages appear, verify the permissions in /etc/exports on the server machine. Read and write
permission must be given to the hosts. The appropriate line should look similar to the following:
/usr/discreet/clip *(rw,sync,no_root_squash
Verifying that NFS and Automounting Daemons are Running
These daemons are installed and running by default. Use the following procedures to verify that these
daemons are running. Network File System (NFS) and automounting daemons (AMD on Linux) must be
running for Wire transfers to work. To start NFS and AMD:
1 Run: chkconfig --list | grep nfs and then chkconfig --list | grep amd
2 Verify that NFS and AMD are set to “on” for run levels 3,4, and 5.
3 If NFS or AMD is off on any of those run levels, run: chkconfig nfs on and chkconfig amd on
4 Restart your network: /etc/init.d/network restart. You might also consider rebooting your
workstation.
Checking the Status of Network Interfaces
If you continue to have problems with your network, you should verify that your network interfaces are up
and running:
1 Run: ifconfig
■ If your network interface is up and running, an “up” appears in the broadcast report for the interface.
The report includes a line similar to the following: UP BROADCAST RUNNING
MULTICASTMTU:1500Metric:1
■ If your network interface is not up and running, check the connections on your network card. A
green light appears when there is a good connection between your network card and its destination.
If you must reconnect cables on Linux, you must restart the network interface. To restart a network
interface, run: ifconfig <interface_name> up
Viewing InfiniBand Statistics
This section describes how to view port statistics for the workstation and InfiniBand switch, and how to
obtain InfiniBand log files. For more information about configuring, monitoring, and managing the InfiniBand
switch and network, see the documentation provided by the manufacturer of your InfiniBand switch.
Viewing InfiniBand Information for a Workstation
The InfiniBand driver installed on your workstation provides two commands that output statistics and
information about InfiniBand ports. Log in as root, and type the following commands in a terminal:
cat /proc/iba/ <driver_id> /1/port <x> /stats
cat /proc/iba/ <driver_id>/1/port <x> / info
where <x> is the port number on the device, and <driver_id> is the HCA driver ID for your device, for
example: mt25218. A report appears in the terminal for each command. To find out the HCA (Host Channel
Adapter) driver ID, type ls /proc/iba/ | grep mt . The driver number, beginning with mt, will be returned.
Generating InfiniBand Log Files for Support
The script /sbin/iba_capture gathers information about your system and InfiniBand configurations that
can be useful for troubleshooting InfiniBand issues. This script outputs a GZIP file.
