118 Sun StorEdge Network FC Switch-8 and Switch-16 Installation and Configuration Guide • October 2001
Managing Without a Volume Manager
Youcan use the Sun StorEdge Traffic Manager software to manage multiple paths to
a device.
1. Install the drivers.
2. Enable the Sun StorEdge Traffic Manager software system-wide by setting the
mpxio-disable fieldin the /kernel/drv/scsi_vhci.conf file to “no”.
Additional explanation of this file is provided in the Sun StorEdge TrafficManager
Installation and Configuration Guide.
3. Configure each Fibre Channel host adapter on the system to either use or not use
this feature.
Youdo this by setting the mpxio-disable flag in the .conf file for each adapter (for
example, /kernel/drv/qlc.conf)to“no”or“yes”.
This procedure is described in detail in the Sun StorEdge TrafficManager Installation
and Configuration Guide.
Managing With VxVM/VxDMP
Youcan manage the Sun StorEdge Traffic Manager software with VxVM versions 3.2
and later using the same techniques you would use on a system without VxVM, as
described in the previous section.
The Sun StorEdge TrafficManager software does not support VxVM versions
previous to version 3.2.
Managing With the Solstice DiskSuite Software
If you are using the Solstice DiskSuite software as your volume manager,you must
unconfigure it and then reconfigureit after you have enabled the Sun StorEdge
TrafficManager software. The Sun StorEdge Traffic Manager software renames the
storage devices that Solstice DiskSuite uses. This process is not difficult, and it is
described in the Sun StorEdge TrafficManager Installation and Configuration Guide.
Caution – This process can result in data loss if done incorrectly.
