Display Status Information

The status command displays MPIO status information, including the timeout value, whether MPIO is enabled (globally and per-device), and any targets specified with the active command. Use the -loption to display more information about the targets, as in the above example.

$ mxmpio status

In contrast with the earlier example, this example shows output for a system that is not MPIO:

#/opt/polyserve/sbin/mxmpio status -l MPIO Failover is globally enabled

psd1	Failover	Timeout	Targets
psd1	enabled	30000	0.	(41:50) scsi2/0/2/19
psd1p1	enabled	10000	0.	(41:51) scsi2/0/2/19
psd1p2	enabled	30000	0.	(41:52) scsi2/0/2/19
psd2	enabled	30000	0.	(41:10) scsi2/0/1/20
psd2p1	enabled	10000	0.	(41:11) scsi2/0/1/20
psd2p2	enabled	30000	0.	(41:12) scsi2/0/1/20

Set the Timeout Value

The default timeout period for PSD devices is 30 seconds. If you need to modify this value for a particular PSD device, use the following command. value is in milliseconds; however, the smallest unit is 10 milliseconds. A value of zero disables timeouts.

#mxmpio timeout value [PSD-device]

Show Number of Transient Errors

The mpiostat command lists the number of transient errors for each target and shows the number of failovers and fatal errors for each device. Values represent the number of respective events since the device was bound. If devices have not been rebound since boot, then this represents the number of events since boot.

Show Load Statistics

The mpioload command shows the load (number of pending I/Os, both total and raw) 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.
