Boot from HP XP - EFI does not see devs at startup

Maxim Yakimenko — Wed, 01 Apr 2009 13:42:32 GMT

Hi, collegues

I try to install 11.31
LUN from XP presented to server, I used drvcfg -s to set boot wwn, after boot EFI sees only CD, after I do reconnect -r and map -r EFI sees them, I start installation from CD and installation does not see devices again. What's wrong?

1,Check the Lun number of the ldev that is presented to the HPUX Serer..

2, Check the HBA Card.

Check the link if its gives some details

This LUN was already presented to this server earlier and boot was setup - but server and XP were interconnected by another pair of FC switches - we moved them into another pair. Zonning ok, XP sees WWN of server, I even managed to start from this LUN booting of previosly installed HPUX (of course,it did not boot up correctly due to path change). So I wonder - why devices appear in EFI only after reconnect -r and map -r and disappear after reboot and 11.31 installation does not see them.

This is what is need to do when you have bl860c

Integrity Blade BL860c Boot Over SAN

By default the EFI only looks for LUNs on the SAN if it is in its boot list. If you've presented and zoned a new LUN that you want to make visible to EFI to boot off, you need to change this in the EFI shell:

It seems that setting this for one card, sets it for all.

Shell> drivers [note the number in the first column of a FC HBA, e.g. 1C ]

Shell> drvcfg [find row where number above in first column, e.g. 1C, then note the number in the second column e.g. 1F]

Configurable Components

Drv[12] Ctrl[13] Lang[eng]

Drv[1C] Ctrl[1F] Lang[eng] Ã note this row

Drv[26] Ctrl[2A] Lang[eng]

Shell> drvcfg -s 1c 1f
Set Configuration Options
Drv[1C] Ctrl[1F] Lang[eng]
Fibre Channel Driver Configuration Utility

4. Edit Boot Settings

6. EFI Variable EFIFCScanLevel []

EFI Variable EFIFCScanLevel not found, create?: y

EFI Variable EFIFCScanLevel [0]?: 1

to set this variable to 1 to search for all LUNs when booting

0. Previous Menu

12. Quit

Then

EFI> reconnect -r

EFI> remap -r
