Finding the WWN in Solaris followup – making it easier
In the previous post I listed the ‘long way round’ to find out the WWN from active HBA links in Solaris. The commands I listed before will work on all recent releases of Solaris. If you’re able to migrate to Solaris 10, you can make things easier for yourself.
cfgadm will take a verbose flag, which will print out a listing that includes the full device path. This will definitely work on Solaris 9 and 10 – I’m afraid I don’t have an 8 box to test though.
bash-3.00# cfgadm -lv Ap_Id Receptacle Occupant Condition Information When Type Busy Phys_Id c0 connected configured unknown unavailable scsi-bus n /devices/pci@7c0/pci@0/pci@1/pci@0/ide@8:scsi c1 connected configured unknown unavailable scsi-bus n /devices/pci@7c0/pci@0/pci@1/pci@0,2/LSILogic,sas@2:scsi c2 connected configured unknown unavailable fc-private n /devices/pci@780/pci@0/pci@8/SUNW,qlc@0/fp@0,0:fc c3 connected unconfigured unknown unavailable fc n /devices/pci@780/pci@0/pci@8/SUNW,qlc@0,1/fp@0,0:fc c4 connected configured unknown unavailable fc-private n /devices/pci@7c0/pci@0/pci@9/SUNW,qlc@0/fp@0,0:fc c5 connected unconfigured unknown unavailable fc n /devices/pci@7c0/pci@0/pci@9/SUNW,qlc@0,1/fp@0,0:fc usb0/1 empty unconfigured ok unavailable unknown n /devices/pci@7c0/pci@0/pci@1/pci@0/usb@5:1 usb0/2 empty unconfigured ok unavailable unknown n /devices/pci@7c0/pci@0/pci@1/pci@0/usb@5:2 usb1/1.1 empty unconfigured ok unavailable unknown n /devices/pci@7c0/pci@0/pci@1/pci@0/usb@6/hub@1:1.1 usb1/1.2 empty unconfigured ok unavailable unknown n /devices/pci@7c0/pci@0/pci@1/pci@0/usb@6/hub@1:1.2 usb1/1.3 empty unconfigured ok unavailable unknown n /devices/pci@7c0/pci@0/pci@1/pci@0/usb@6/hub@1:1.3 usb1/1.4 empty unconfigured ok unavailable unknown n /devices/pci@7c0/pci@0/pci@1/pci@0/usb@6/hub@1:1.4 usb1/2 empty unconfigured ok unavailable unknown n /devices/pci@7c0/pci@0/pci@1/pci@0/usb@6:2
If you have Solaris 10 8/07 or later, then you’ll find that the dump_map option to luxadm will take the short notation for an HBA that cfgadm uses.
bash-3.00# luxadm -e dump_map /dev/cfg/c2 Pos AL_PA ID Hard_Addr Port WWN Node WWN Type 0 1 7d 0 210000e08b86f840 200000e08b86f840 0x1f (Unknown Type,Host Bus Adapter) 1 ad 23 ad 50060e8014118960 50060e8014118960 0x0 (Disk device)
Again, this all works only if the HBA has a live link – it needs some cable plugged in, and you need to have something listening at the other end. I’ll be exploring how to find the WWN of your HBAs – even if they’re not plugged in – soon, using some other features of Solaris.
