#Addr Luns wwnn wwpn portid wwn wwnn wwpn portid Storage wwnn and wwpn (if fabric: port identifier). switch port wwn that the hba is attached to (if fabric). HBA wwnn and wwpn (if fabric: port identifier). kernel assigned scsi address plus sdN and sgN names.The command route description from host to a san storage disk, or other type of scsi device, that an io command takes consists of the following information: The following describes commands that can be used to retrieve various wwn and identifiers associated with storage and how to combine them in useful ways. How do I find the WWID (world wide identifier) of attached disks and other scsi devices?Īlthough no supported tool exists to create a full storage topology view on SAN configurations, simple programs or scripts can be written that integrates the information available within the kernel into different useful forms and reports. How do I find the WWPN and WWNN (world wide node name) of attached storage ports?. How do I locate the world wide name of an hba?. How do I locate the world wide number of an hba WWPN (world wide port name)?. How do I lookup WWN of installed HBAs?. How to check HBA host and its corresponding WWPN?. How can I determine which disks and scsi devices are behind which storage port wwn?. How do I find the port_name(WWPN) and node_name(WWNN) of a configured HBA in Red Hat Enterprise Linux ?.When a system is connected to multiple SANs of the same type it is hard to tell what disk is on what SAN, or what disk, tape, changer, and other scsi devices are served by which storage processor port.Release Found: Red Hat Enterprise Linux 5, 6, 7 Problem
