Making a SAN boot LUN the primary boot LUN for HP-UX QLogic HBAs after transition
If your Data ONTAP operating in 7-Mode HP-UX host was SAN booted, you must make the SAN boot LUN the primary boot LUN after transition to clustered Data ONTAP.
-
Your data migration must be complete.
-
Your boot LUN must be mapped to your host from your clustered Data ONTAP node.
SAN boot is supported for HP-UX 11.3x on HP 9000 systems using the BCH menu and on HP Integrity servers using the HP-UX Loader (EFI).
For copy-based transitions, perform these steps after completing the Storage Cutover operation in the 7-Mode Transition Tool. Copy-free transitions are not supported on HP-UX hosts.
-
Open the shell prompt:
Ctrl B
-
Boot to the EFI shell.
The EFI shell is available only on HP Integrity systems.
-
Use a serial console to access the login to the service processor (MP).
-
Access the console list:
CO
This opens the EFI Boot Manager menu.
-
From the EFI Boot Manager menu, select the EFI shell menu option to access the EFI shell environment.
-
Identify your QLogic driver numbers:
drivers
The driver numbers are located in the DRV column.
-
Identify the corresponding controller number for each driver:
drvcfg driver_number
In the following example,
27
is the corresponding controller number for driver23
and26
is the corresponding controller number for driver24
:Shell> drvcfg 23 Configurable Components Drv[23] Ctrl[27] Lang[eng] Shell> drvcfg 24 Configurable Components Drv[24] Ctrl[26] Lang[eng]
-
Open the driver BIOS:
drvcfg drv_number ctrl_number -s
-
Enter

to select 4. Edit Boot Settings. -
In Edit Boot Settings, enter
6
to select 6. EFI Variable EFIFCScanLevel. -
Enter
1
to change the value of EFI Variable EFIFCScanLevel from 0 to 1. -
Enter
7
to select 7. Enable World Login. -
Enter
y
to enable world login. -
Enter
0
to go to the previous menu. -
In the Main Menu, enter
11
to save your changes. -
Enter
12
to quit. -
In the shell prompt, rescan your devices:
reconnect -r
-
Display the LUN to obtain the path of the LUN from which you want to boot:
map -r
The LUN paths are listed under the Device column. The bootable SAN disk are displayed under the mapping table column and have “WWN” and “Part 1” in the output string.
-
Enter the LUN path of your SAN boot LUN.
An example of a LUN path is fs0.
-
Exit the EFI shell:
cd efi
-
Enter the HPUX directory:
cd hpux
-
Make the new clustered Data ONTAP SAN boot LUN the primary boot LUN:
bcfg boot add 1 hpux.efi "HP-UX-Primary Boot"
-
Manually update the HBA BIOS by making an entry in the EFI for the SAN boot LUN.
-
Create an alternate boot path:
bcfg boot add 2 hpux.efi “HPUX alternate boot”
-
Create a third boot path:
bcfg boot add 2 hpux.efi “HPUX third boot”
-
Create a fourth boot path:
bcfg boot add 2 hpux.efi “HPUX fourth boot”
