Chapter 1: Matrix Server Commands

-u

Display I/O latencies in microseconds instead of the default milliseconds. This option applies only to the iostat command.

The commands are:

enable/disable

Enable or disable MPIO failover on the specified devices.

enableall/disableall

Globally enable or disable MPIO failover on this node.

timeout value

Set the timeout on the specified device.

active target

Set the active target on the specified device.

mpiostat

List the number of transient errors for each target and show the number of failovers and fatal errors for each device.

mpioload [interval [count]]

Shows the load for each target (SCSI command I/Os) and total for the PSD device (block layer I/Os), number of failovers, and fatal errors for each device.

iostat [interval [count]]

Show general I/O statistics for each device.

iostat [interval [count]]

Dump general I/O statistics for each device in a raw format.

Enable or Disable Failover for a Server

A matrix server can use multiple FC ports to connect to the FibreChannel fabric. If the FC port or FC switch currently being used for I/O should fail, Matrix Server will by default fail over the I/O to another FC port/FC switch path.

You can use the following command to control whether this failover behavior can occur on a particular node. Run the command on the server where you want to change the failover behavior. (Matrix Server starts with failover enabled.)

#mxmpio enablealldisableall
