mpath (mp) path = devicepath
[id = productid ]
[pmgr = managername ]
[lmgr = managername ]
[pmgrpri = managerpriority ]
[maxios = maxconcurrentchannel I/Os]
mvol (mv) vname = volumename
[newname = newvolumename ]
[ldev = logicaldevice# ]
[transient = %ofdiscfortransientobjects ]
[permanent = %ofdiscforpermanentobjects ]
[vclass = volumeclass ]
To view the syntax for a specific I/O configurator command, enter HELP commandname at the
I/O configurator prompt. Refer to Example 5-3, to get information about the ADEV
command, you would enter HELP ADEV.

Using I/O Configurator Commands
The I/O configurator commands let you list, modify, add, and delete four types of objects:
classes, devices, paths, and volumes. You can also use the I/O configurator to modify
addresses with the MADDRESS command. In addition to the specific functions, shown in
Table 5-1., the I/O configurator includes the commands that are common to all SYSGEN
configurators: CLEAR, EXIT, HELP, HOLD, and OCLOSE.
