Updating the blacklist section

With the default settings, UTM LUNs might be presented to the host. I/Os operations, however, are not supported on UTM LUNs. To prevent I/O operations on the UTM LUNs, add the vendor and product information for each UTM LUN to the blacklist section of the /etc/multipath.conf file.

About this task

This optional task allows you to remove virtualized disks, as well as disks from other storage arrays that are managed by other multipath drivers.

Note: For SANtricity 8.40, NetApp recommends that you verify the default settings and do not modify any settings.

The entries should follow the pattern of the following example.

blacklist {
       device {
              vendor "*"  
              product "Universal Xport"
       }  
}
