3.1.2 Matrix Server Administration Guide

Chapter 15: Test Your Configuration 197

Test SAN Connectivity and Shared Filesystem

Operation

Use the following procedure to test basic SAN connectivity and shared

filesystem operation in your matrix:

1. From the Management Console, log into one of the matrix servers.

2. Import an unused SAN disk into your matrix configuration.

3. Create a PSFS filesystem on an unused partition on this disk.

4. Mount the PSFS filesystem on each server in the matrix. This

filesystem will now be shared by these servers.

5. Log into each of the servers as root. From the shell prompt, perform

some basic I/O tests to the shared filesystem using a tool such as tar.

Verify that changes to the filesystem made by each server are visible to

all other servers in the matrix.

Test Filesystem Failure Recovery

1. Configure the matrix with a shared filesystem as described in the

previous procedure.

2. Pull the LAN network connection(s) from one of the servers. Verify

that this server is unable to access the shared filesystem. Verify that

the other servers in the matrix are still able to access the shared

filesystem.

3. Reconnect the LAN network to the server and then reboot it. Verify

that the server, upon rebooting, is able to mount the shared filesystem.

Verify that all servers are able to access the shared filesystem.

4. Pull the SAN network connection(s) from one of the servers. Verify

that this server is unable to access the shared filesystem. Verify that

the other servers in the matrix are still able to access the shared

filesystem.

5. Reconnect the SAN network to the server and then reboot it. Verify

that the server, upon rebooting, is able to mount the shared filesystem.

Verify that all servers are able to access the shared filesystem.
