HP StorageWorks Disk Array XP operating system configuration guide: MPE/iX (A5951-96145, November, 2005)

The Port ID column of the display has the information needed to form the FC N-Por t

part of the I/O path. The Port ID is a 6-character hexadecimal digit (3 bytes) that

decomposes into the three portions (Domain.Area.Port) of the FC N-Por t p art of the I/O

path. Since PDC boot paths are set as decimal numbers, these three portions of FC

N-Portvaluehavetobeconvertedfromhextodecimalbeforeyoucanusethemtoset

the primary boot path.

Example for Port #5, Port ID 011532

In the Name Server display above, the disk array on Por t 5 has Por t ID = 011532,

hexadecimal. T

digit h ex number into its 3 hex bytes, and convert each hex byte to its decimal equ ivalent.

The resulting three decimal numbers become the FC N-Port (Domain.Area.Port) portion

of the primary boot path:

• 011532 hex —>

01 15 32

• 01hex—>01decimal

• 15hex—>21decimal

• 32hex—>50d

ecimal

so the FC N-Port portion of the I/O path is 1.21.50.

Composing the entire primary I/O boot path

You can now form the entire primary I/O boot path for PDC by combining:

• the HBA part of the path, 0/6/0/0

• the FC N-Po r t part of the path, 1.2 1 .50

• your selected SCSI LUN within the disk array, for this example: 0.0.2

(bus.target.lun)

to get the complete primary I/O boot path 0/6/0/0.1.21.50.0.0.2.

Now set the system’s primary boot path to that value, and then install the OS from

the SLT tape.

When you are ﬁnished loading the OS, return to section titled Conﬁgure the disk array

devices in MPE/iX.
