FC disks with Service Guard

On RP5470 servers with fiber channel disks how can I confifure Host ID ?
I have a cluster with 2+1 nodes (RP5470 servers)with MC/Service Guard.

In the past with K/R/L/N servers and SCSI disks, I configured Host ID by programming switch SCSI card or by setting scsi init command through SCSI Servive Menu commands.

With Fibre Channel you do not need to do this. It is different to using straight forward SCSI addressing.

Hi,

For Ultra2 PCI SCSI cards refer

http://docs.hp.com/hpux/pdf/A5149-96003.pdf

In page number 42 telling to use SCSI command
(SCSI command available from ISL i.e. Autoboot off or interrupted boot)

Or give a search for SCSI controller in http://docs.hp.com

Setting SCSI IDs
================
To use the SCSI command to set the initiator (SCSI) ID for an adapter,
follow this syntax:
SCSI init bus_number slot_number ID_number
where
bus_number Specifies the number of the bus the adapter is installed
on.
slot_number Specifies the number of the slot the adapter is in.
ID_num Specifies the adapter???s SCSI ID number.
For example, to set the SCSI ID for the adapter installed on bus 5 slot 2
to 6 and then display the results, issue these commands:
SCSI init 5 2 6
SCSI init 5 2
The output (of the second command) could look something like this:
PCI device /5.2 = 6

Please read the entire manual for consequences of changing the controller IDs.
Also refer to the correct hardware model.
