I have great confusion identifying my disks at EFI level....I really dont know what is evey PUN and LUN combination points to. Below are the details,
I have 6 disks ( all are bootable ) I can see the primary and secondary boot path since it shows directly the HW path and I have no issue booting my server from PRI and ALT, but when it comes with the other 4 disks I am blank...
Here are my disks visible in OS,
disk 0 0/0/0/2/1.2.0 sdisk CLAIMED DEVICE Optiarc DVD RW AD-5170A
disk 1 0/0/0/2/0.6.0 sdisk CLAIMED DEVICE HP 73.4GST373454LC
disk 2 0/0/0/3/0.6.0 sdisk CLAIMED DEVICE HP 73.4GST373454LC
disk 3 1/0/0/2/0.6.0 sdisk CLAIMED DEVICE HP 73.4GST373454LC
disk 4 1/0/4/1/1.0.0 sdisk CLAIMED DEVICE HP 73.4GST373454LC
disk 5 1/0/4/1/1.2.0 sdisk CLAIMED DEVICE HP 73.4GST373454LC
disk 6 1/0/4/1/1.4.0 sdisk CLAIMED DEVICE HP 73.4GST373454LC
disk 7 1/0/4/1/0.2.0 sdisk CLAIMED DEVICE Optiarc DVD RW AD-5170A
A view of same disks from EFI :
fs0 : Acpi(HWP0002,PNP0A03,0)/Pci(2|0)/Scsi(Pun6,Lun0)/HD(Part1,SigC37DCDFC-4FD0-11DC-8002-D621

blk5 : Acpi(HWP0002,PNP0A03,0)/Pci(2|1)/Scsi(Pun2,Lun0)/CDROM(Entry0)
blk6 : Acpi(HWP0002,PNP0A03,0)/Pci(2|1)/Scsi(Pun2,Lun0)/CDROM(Entry1)
blk7 : Acpi(HWP0002,PNP0A03,0)/Pci(3|0)/Scsi(Pun6,Lun0)
can anyone guide me if I want to boot from disk 6 ( 1/0/4/1/1.4.0 ) which fsN/blkN I have to select ?
Thanks,
Vijayy

Re: Identifying Hardware in EFI
The pathes are in the manual, but as a workaround with the OS running you can do
ioscan -fne
the "e" will display the EFI pathes too.
Hope this helps!

Torsten.

Be careful when dealing with efi, initial map "may not" show the correct number of disks connected to the system.
In efi shell, always remember to issue command: "search all"
Thanks
