Enabling Boot On SAN for A500 + SD3200 HP/9000 Server

Enabling Boot On SAN for A500 + SD3200 HP/9000 Server

Hello,

The goal is to switch from "SCSI internal disk" boot to "DS8300 disk" boot thru the SAN.

I searched many ressources on the Web but didn't find something really relevent.

I run HP-UX 11.11 on PA-RISC :
model : 9000/800/A500-5X
FC card A5158
and
model : 9000/800/SD32000
FC card A6795

The SD32000 is my target system (production) and the A500 is my sandbox.

I begin the operation on my A-Class server as "sandbox" :
Upgrade PDC to 43.50 (latest version)
Allocate a 32G disk on the DS8300
mirror the current vg00 to the new PV (pvcreate -B, mkboot -a "hpux -lq", lvlnboot, ...)

Now, at the reboot here is the situation :
search (sea) command effectively list all the cards (2 SCSI internal for intrernal disk, 1 SCSI for the DDS tape, 2 FC card)
when I select the correct PATH (bo P5 in my case) to boot on the FC card, the console stop with message :
-----------------------
Booting...
Failed to initialize.

ENTRY_INIT
Status = -7

Failed to initialize.
-----------------------

I'm back to the menu...

If someone have good information's either :
- on the Boot On SAN for A-Class and Superdome
- or this specific boot error (-7)

I'll enjoy :o)

Re: Enabling Boot On SAN for A500 + SD3200 HP/9000 Server

Hello, why do you want to boot from SAN? There are many disadvantages in booting from SAN, and many advantages to stay booting from local internal disk. Booting from SAN is a bad idea for most environments...

Some tips or maybe other solutions found through here. There is a reference to reviewing the Fibre HBA doc that may also lead someewhere.

HBA and array must be supported for boot.



You cannot search the SAN from boot menu.

Boot up to hpux and use "setboot" to set the boot path.

Hope this helps!

Re: Enabling Boot On SAN for A500 + SD3200 HP/9000 Server

Hello all,

Thank you for your answers.
Next week, I'll install 2x A6795 FC card (listed in the white paper as supported/compatible with boot on SAN)

I'll let you know if it solve the issue or not.

Just FYI, I tried to turn the SAN disk as PRImary (thru setboot) and let the server reboot without interact and it finally boot on the SCSI disk defined as alternate (right now I suppose it's because I use A5158 FC card whitch is not listed in the white paper).

Have a nice WE
