Obtaining Worldwide Numbers

Use the ldm list-hba -u command to view a device's WWN and all the paths that reference the device's WWN.

The following example shows information about the physical devices in the primary domain. The example output shows both the paths that reference the naa.600c0ff0000000000089d513107ecb00 WWN of the physical device.

primary# ldm list-hba -u primary
DOMAIN
primary
 
naa.600c0ff0000000000089d513107ecb00
    /SYS/MB/RISER1/PCIE4/SUNW,qlc@0/fp@0,0/w216000c0ff8089d5,0 
    /SYS/MB/RISER1/PCIE4/SUNW,qlc@0,1/fp@0,0/w216000c0ff8089d5,0
...

By including the -l option, the ldm list-hba -u -l command shows per-path and per-device metadata that you can use to identify a specific physical device within your system's topology.

primary# ldm list-hba -u -l primary
DOMAIN
primary
 
naa.600c0ff0000000000089d513107ecb00
    /SYS/MB/RISER1/PCIE4/SUNW,qlc@0/fp@0,0/w216000c0ff8089d5,0
    [/pci@0/pci@0/pci@8/pci@0/pci@2/SUNW,qlc@0/fp@0,0/ssd@w216000c0ff8089d5,0]          (c0t600C0FF0000000000089D513107ECB00d0s0)
    /SYS/MB/RISER1/PCIE4/SUNW,qlc@0,1/fp@0,0/w216000c0ff8089d5,0
    [/pci@0/pci@0/pci@8/pci@0/pci@2/SUNW,qlc@0,1/fp@0,0/ssd@w216000c0ff8089d5,0]        (c0t600C0FF0000000000089D513107ECB00d0s0)
...

By using the metadata in the previous example output, you can add the device associated with this WWN to the my_vsan virtual SAN.

In the following example, first create the my_vsan virtual SAN on the my_domain domain. Then, add the physical device associated with the naa.600c0ff0000000000089d513107ecb00 WWN to the my_vsan virtual SAN:

primary# ldm add-vsan mask=on $iport_path my_vsan my_domain
primary# ldm add-vsan-dev my_vsan naa.600c0ff0000000000089d513107ecb00
