Please explain the hardware path of disk in HPUX

[senthil_kumar_1]

Local Disk:

disk 4 10/0/15/1.5.0

San Disk:

disk 2 10/2/1/0.1.25.0.0.0.0

[Torsten. · Accepted solution]

It could be better with more details about your hardware, but however:

1) 10/0/15/1
path to slot and HBA
disk has SCSI id 5

2)10/2/1/0
path to slot and HBA
switch domain ID 1
storage is connected to port 25
LUN ID is 0

Let me guess, this is probably a workstation, maybe a J-class ...

Hi Senthil:

An 'ioscan' and a 'lssf' can help you understand. See the manpages for each.

Hi Senthil,

Hope this would be helpful..Pls check and let me know.

Hardware Path Interpreting:

Sample IOSCAN output from HPUX 11.23 server showing FC HBA, EVA Controller and one LUN.

fc 0 0/6/2/0 fcd CLAIMED INTERFACE HP A6826-60001 2Gb Dual Port PCI/PCI-X Fibre Channel Adapter (FC Port 1)
/dev/fcd0
fcp 2 0/6/2/0.1 fcd_fcp CLAIMED INTERFACE FCP Domain
ext_bus 26 0/6/2/0.1.0.0.0 fcd_vbus CLAIMED INTERFACE FCP Array Interface

/dev/dsk/c26t0d1 /dev/rdsk/c26t0d1

FC Addressing Syntax:
HBA.Domain.Area.Port.Bus.Target.LUN
Resolving the above example:
HBA = 0/6/2/0
Domain = 0/6/2/0.1 (Here â 1â is Domain ID nothing but a FC Switch Domain ID)
Area = 0/6/2/0.1.0
Port = 0/6/2/0.1.0.0
Bus = 0/6/2/0.1.0.0.0
Target = 0/6/2/0.1.0.0.0.0
LUN = 0/6/2/0.1.0.0.0.0.1
