value is too large, more time may be needed for filesystem recovery after a node failure. The following example sets the timeout to 10,000ms (10 seconds): sanpulse_start_options = { "--mxinit","-o sdmp_io_timeout=10000" }; After adding the parameter, you can restart HP Scalable NAS. A setting of 10,000ms will be adequate for many storage arrays. If you are using DDN storage, you may need to increase the parameter beyond 10,000ms. NOTE: If you increased the parameter and are still experiencing I/O timeouts, a different issue may be causing the problem. Contact HP Technical Support for assistance. Servers Change the fencing method This procedure describes how to change the cluster fencing method on servers that are already running HP Scalable NAS. 1. Stop HP Scalable NAS on all servers in the cluster: # /etc/init.d/pmxs stop 2. Reboot all servers having entries in the HP Scalable NAS host registry. Use this command to see a list of the affected servers: # /opt/hpcfs/lib/mpdump 3. Clear the host registry on the cluster Use the mprepair --clear_hr command as described under mprepair options, page 367. 4. Run the Management Console from one server in the cluster. Skip the opening windows and then configure the appropriate fencing method. 5. When you have completed the fencing configuration, skip the membership partition configuration windows and then export the new configuration to the other servers in the cluster. 6. Start HP Scalable NAS on each server: # /etc/init.d/pmxs start HP Scalable NAS File Serving Software administration guide 371
