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 -l option 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

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

Display MPIO Statistics

mxmpio also includes the following commands, which display various

MPIO statistics. See the mxmpio(8) man page for details about these

commands.

mpiostat Display the number of transient errors for each target, and

show the number of failovers and fatal errors for each

device.

mpioload Display load information for each target and the PSD

device, and show the number of failovers and fatal errors

for each device.

The output is intended for use in programs.
