1. Issue the # DMSETUP VERSION command. The output is similar to the following output:

   Library version: 1.00.09-ioctl (2004-03-31)
   Driver version: 4.4.0

   or

   Issue the following command to determine the version using the rpm:

   # rpm -q -a |grep device-mapper

   The output is similar to the following output:

   device-mapper-1.00.09-17.5

   The library version must be Version 1.01 or later.
2. Verify the installation after the upgrade.

   # rpm -Uvh device-mapper-1.01.01-1.6.i586.rpm
   Preparing... ########################################### [100%]
   1:device-mapper ########################################### [100%]
   # rpm -q -a |grep device-mapper
   device-mapper-1.01.01-1.6

   You can also check the /lib directory to see that the correct versions are installed. A system with the correct levels would have the following information:

   # ls -l /lib/libdev*
   lrwxrwxrwx 1 root root 20 Jul 5 11:42 /lib/libdevmapper.so 
   ->libdevmapper.so.1.01
   -rwxr-xr-x 1 root root 24490 May 23 2005 /lib/libdevmapper.so.1.00
   -rwxr-xr-x 1 root root 28216 May 23 2005 /lib/libdevmapper.so.1.01
