_Unknown _volumes are currently not supported by the Usage plugin
included in version 3.4.0. As a workaround we recommend excluding the respective volumes via the X switch after having verified their unknown state using -explore. As of the next release (3.4.1) the plugin will skip unknown volumes (and outputs the number of skipped volumes). In verbose mode (-v) the reason for the exclusion can be inspected. Example:“`
$ perl check_netapp_pro.pl Usage -H 123.45.78.31 -o volume -v
NETAPP_PRO USAGE CRITICAL – 47 volumes checked, 9 critical and 21 warning
4 skipped. (-v shows reason)
(…)
Usage 203 Volume ‘FCP_SAP04SE’ skipped because state is offline
Usage 203 Volume ‘FCP_SAP04SF’ skipped because state is offline
Usage 203 Volume ‘c_kanu_1’ skipped because state is unknown
Usage 203 Volume ‘c_kanu_2’ skipped because state is unknown
