Linux Host Utilities is a NetApp host software that provides sanlun commands on your Linux host. The sanlun utility is installed automatically when you install the NetApp Host Utilities package. This utility provides the sanlun commands that you can use to manage ONTAP LUNs and host bus adapters (HBAs). The sanlun commands return information about the ONTAP LUNs mapped to your host, multipathing, and information necessary to create initiator groups.

In the following example, the sanlun lun show all command returns ONTAP LUN information:

controller(7mode/E-Series)/            device     host               lun
vserver(cDOT/FlashRay)   lun-pathname  filename   adapter  protocol  size    Product
------------------------------------------------------------------------------------
data_vserver          /vol/vol1/lun1   /dev/sdb   host16   FCP       120.0g  cDOT
data_vserver          /vol/vol1/lun1   /dev/sdc   host15   FCP       120.0g  cDOT
data_vserver          /vol/vol2/lun2   /dev/sdd   host16   FCP       120.0g  cDOT
data_vserver          /vol/vol2/lun2   /dev/sde   host15   FCP       120.0g  cDOT
