Set up EVMS for use with Multipathing

Have multiple paths to SAN
Want to use multipath devices with EVMS
EVMS administration utilities show multiple devices that are the same physical device

This is a known problem. The current workaround is to filter out the devices EVMS will look at. To do this, edit your /etc/evms.conf. There is a section for sysfs_devices. Inside is an exclude parameter. Put in "sd*", this will filter out all the regular disk devices such as sda, sdb, etc. Note that if you have a non-multipathed device, it will also filter out this device. This could be a problem if you have local, non-multipathed evms volumes.

Your resulting sysfs_devices section should look something like this:

sysfs_devices { include = [ * ] exclude = [ sd* ] }
