how to define h/w path 0/1/1/0.0.0 ?

[natis]

What does it mean for each digit?
please, suggest me

Hi,

The HP-UX addressing scheme assigns fixed and hierarchical hardware paths to the devices,
based on the SCSI-2 specification. 14 bits are divided as follows:
Bus (7 bit = 128 busses)
Target (4 bit = 16 targets)
Lun (3 bit = 8 luns)
The HW path to a SCSI disk would look like this:
[SCSI-HBA].[Bus].[Target].[Lun]

'0/1/1/0' is the bus, '0' is the target and the last digit '0' is the lun. how the first few digits are defined is all on the system hardware architecture which only hp will know in details.

Hi,

Addressing scheme is like this...

First digit 0 --> System Bus
Second digit 1 --> SBA(System Bus Adapater)
Third digit 1 --> LBA (Local Bus Adapter)
Fourth digit 0 --> Controller instance number
Fifth digit 0 --> Target number
Sixth digit 0 --> Lun Number

Hope this helps.

One last note:

If this is a cell based server then the first digit/place indicates the cell #.
