Following is a checklist of the steps you must perform when installing and configuring a CXFS system.
 | Caution: CXFS is a complex product. To ensure that it is installed
and configured in an optimal manner, you must purchase
initial setup services from SGI.
This checklist is not intended to be used directly by the customer, but is provided for reference. It is intended to be used only as an aid; you must be certain to read this entire manual, especially Chapter 10, “Troubleshooting”, before attempting to complete these procedures. |
[ ] | Understand the application use, storage configuration, and I/O patterns at the site. (Not all applications benefit from CXFS; see “Comparison of XFS and CXFS” in Chapter 1.) | |
[ ] | Connect the SAN hardware. See the following documents (only available to SGI service personnel):
| |
[ ] | Is there a private network? This is a requirement. SGI recommends a network switch rather than a hub for performance and control.
| |
[ ] | Are there serial hardware reset lines? The reset capability is mandatory to ensure data integrity for clusters with only two server-capable nodes, and it is highly recommended for all server-capable nodes. Larger clusters should have an odd number of server-capable nodes, or must have serial hardware reset lines or use I/O fencing with switches if only two of the nodes are server capable. See “Isolating Failed Nodes” in Chapter 1, and “Serial Hardware Reset” in Chapter 1.

[ ] | Read this book. If you have clients running operating systems other than IRIX, also read the CXFS MultiOS for CXFS Client-Only Nodes: Installation and Configuration Guide.
| |
[ ] | Verify that the network is usable. See Chapter 2, “IRIX Systems: Installation of CXFS Software and System Preparation ”. | |
[ ] | Install the CXFS software. See Chapter 2, “IRIX Systems: Installation of CXFS Software and System Preparation ”. If you have clients running operating systems other than IRIX, also see the CXFS MultiOS for CXFS Client-Only Nodes: Installation and Configuration Guide.
| |
[ ] | Modify the configuration files as needed. Ensure that the contents of the /etc/sys_id file matches the primary name in the /etc/hosts file. See “Configure IRIX System Files” in Chapter 2.
| |
[ ] | Perform other system configuration steps and reboot. See:

| [ ] | |
[ ] | Completely configure a small cluster (3 nodes). See Chapter 3, “Initial Configuration of the Cluster”.
| |
[ ] | Look for errors in the daemon log files in the /var/cluster/ha/logs directory.
| |
[ ] | If all is well, add the rest of the nodes. If there are problems, see Chapter 10, “Troubleshooting”.
| |
[ ] | Set up the filesystems. See Chapter 3, “Initial Configuration of the Cluster”.
