MPE Native Fibre Channel Installation

onto an FC LDEV 1

The following information can be distilled from the MPE/ix 7.5

Communicator at HP's documentation website at

http://www.docs.hp.com/mpeix/all/

MPE/iX 7.5 can be installed to a supported fibre channel disk array, such

as the VA7100, XP1024 and XP128. It is (highly) recommended that

installation be done as a direct connect from the HP e3000's FC HBA A6795A

card to the FC port on the disk array. Then, afterward, you can

reconfigure using the FC switch, if you choose.

Configure the Disk Array

Create Luns and their sizes through the appropriate interface to the array

and set the port setting to "Private-

Loop" and set the port ID to a unique

number between 0 and 255 within your SAN. In our example we have set our

port ID on our VA7100 to 90 and created 10 luns with addresses from 0..9.

FC Hardware Paths

There are two address modes for the paths. The first one is the HP-UX FC

path referred to as the long path. This long path is required by PDC to

locate the boot path. The components of which are described below:

BC / BC / BC / Card . Domain . Area . Port . Bus . Target . LUN

|--------------------| |------------------|

FC NPORT ID FC Lun

0 / 6 / 0 / 0 . 8 . 0 . 90 . 0 . 0 . 0

|--------------|------------|----------|

Card Address FC NPORT ID FC Lun

The second form of the path is referred as the MPE FC Path or short path.

This form is required to configure Ldevs from within SYSGEN. The same

example of the long path will be used in our short path example:

BC / BC / BC / Card . NPort . LUN

0 / 6 / 0 / 0 . 90 . 0

|-------------|------|-----|

Card Address Nport Lun

The utility FCSCAN, executed under MPE can be used to generate both

address paths.

10. Once the direct FC connect has been completed it is recommended that you retain the configuration group in the event that an issue arises that requires debugging of the FC storage array, switch or topology. 11. Connect the HP e3000 FC HBA to a port on the Brocade 2800/2800/3200 or 3800 FC switch and create the zoning for those ports. 12. If you have access to MPE's FCSCAN utility program by using an internal disk as your Ldev 1, run that utility after connecting and verify the new paths.
