No Existing Mpe/Ix Boot Disk Available And Disk Array Is Fibre Channel Switch Connected - HP XP1024 Operating System Configuration Manual

No existing MPE/iX boot disk available and disk
array is Fibre Channel switch connected
Primary boot path format for Fibre Channel devices
Booting from the array
If you have no boot disk and the array is connected to a Fibre Channel
switch, the MAPPER2 utility CANNOT be used to determine the I/O paths
for the disk array devices. Instead, you need to derive the primary boot path
information from the known I/O path of the A6795A Fibre Channel HBA
(recorded at hardware installation time) and the known configuration of
LUNs within the disk array (established earlier with Command View XP or
LUN Configuration Manager). Additional path information must be
obtained by LAN connection of a suitable web browser to the Fibre
Channel switch.
In order to form the desired primary I/O boot path for the disk array to be
used as Ldev 1, you will be combining three parts of the I/O path to make
the whole I/O path in the format required by processor PDC for boot paths:
• The part of the I/O path that belongs to the A6795A Fibre Channel
HBA, plus
• The part of the I/O path that belongs to the disk array's Fibre Channel
interface (the N-Port), plus
• The part of the I/O path that gives the SCSI target ID and LUN
information for a LUN within the disk array.
PDC on A-Class and N-Class systems requires the following format for
combining these I/O path parts:
|-- HBA I/O Path Part --|--- FC N-Port I/O Path Part---|- SCSI LUN I/O Path Part-|
BC / BC / BC / Card . Domain . Area . Port . Bus# . Target ID . LUN
.
0 / 6 / 0 / 0
You should already know the HBA I/O path, recorded when the HBA
hardware was installed and also the SCSI LUN I/O path. The following
section explains how to use a web browser to determine the FC N-Port I/O
path needed to complete the whole primary boot path.
