Problems booting off CDROM drive

[dictum9]

I have an L class running 11.0

It has an external SCSI cdrom drive. I am trying to install a newer OS.

Here is the output of ioscan and also search from the boot prompt. As far as I understand, path 0/0/1/0.1.0 is the CDROM drive which is P0. Yet it won't boot off P0. Why is that?



disk 58 0/0/1/0.1.0 sdisk CLAIMED DEVICE HP DVD-ROM 304
/dev/dsk/c0t1d0 /dev/rdsk/c0t1d0



Path# Device Path (dec) Device Path (mnem) Device Type
----- ----------------- ------------------ -----------
P0 0/0/1/0.1 extscsi.1 Random access media
P1 0/0/1/1.2 intscsib.2 Random access media
P2 0/0/2/0.2 intscsia.2 Random access media
P3 0/0/2/1.0 media.0 Sequential access media



----
Main Menu: Enter command or menu > boot P0

ERROR: Not a boot path

Verify that the CDROM is indeed bootable. If it is then power cycle the CDROM drive. Search for boot devices from the BCH menu; choose the CDROM drive for booting off of. If this doesn't fix it check for bad cables termination HBAs or the drive itself maybe bad.

check if this external cd-rom drive is indeed a supported drive for the L-class server. Do you have the product number of this drive?

[AwadheshPandey]

Most chances are that your ext Drive is not functioning properly. Cross check you extenal drive with some other server and media, also cross check CD-ROM if you have any test server...

Also Check with the different media.

Hi,

Plese check the device with another server and get it confirm that it is working or not. Also check the disk also.

Thanks and regards,

Vinu

check the external drive with conecting to another system. check the installation media is bootable and not scrachy.

must be problem with drive.

An update. I brought the machine back to multiuser state and mounted the CD without any issues. I can cd into /SD_CDROM, into various folders of the Core OS CD.

So the CD rom drive appears to be fine, and the CD appears to be fine. Why can't I boot off of it then?

hi,

in this case, this sound like an incorrect version of hp-ux 11.0 cd, you are using. what is the part number of the cd you use for installing the HP-UX 11.0 OS ?

[dictum9]

I am installing 11i version 1, June 2004.
Core OS
B3920-14084

I don't see how this could be the wrong CD.

[dictum9]

Besides, it doesn't look like I am even getting to the CD at all.

It says

Not a boot path

Hi:

This could be a PDC firmware problem. Check the 11.11 installation guide for requirements and your PDC firmware version with STM.

I would also suggest that you obtain a more current version of the 11.11 OE. June 2004 is a bit old.

Regards!

How do I check the firmware version?

[Doug Burton]

I see your entry showing devices however are they bootable devices (don't think that's been mentioned yet)?

Try this:

Turn the server on.

Place the Install CD into the CD drive while the server is starting up.

Halt the boot process when prompted and execute the following command: sea ipl

The "sea ipl" command will return any and all devices, which are bootable. You will see the device for the CD. If this is a new server you will not see any other drive devices due to the drives not being configured yet. However, you may see a Lan device if you have an Ignite server configured. Of coarse you'll see bootable hard drives if configured.

Your now ready to boot from the CD using the following command: bo p0
I assume "p0" was returned and matches the CD hardware address when the "sea ipl" command ran.
Answer "no" to the "Interact with IPL" prompt.

The rest is fairly easy.

Hi:

# echo "selclass qualifier cpu;info;wait;infolog"|cstm|grep -i firmware

[tkc]

you can run cstm to check the cpu pdc firmware revision :

#cstm
cstm>map

check out the device number for the cpu. (normally the very last line)

cstm>select device
cstm>info
cstm>infolog

this will display and output that will include the pdc firmware revision.

cstm>exit

i did check the pdc firmware for you but don't seem that could be an issue for your problem :

ftp://ftp.itrc.hp.com/firmware_patches/hp/cpu/PF_CRHW4428.txt

[tkc]

but if your 11.11 needs support for OLAR, the minimum required pdc firmware is 40.48

Amazingly, it was a bad CD. It didn't look scratched or anything, but it just wouldn't boot. Incredibly, it would mount just fine like a regular CD and files on it could be accessed.

In any case, I tried a 2003 version of 11.i and it's booting just fine.

Guess I'll have to expand the list of known defects to include the CD also :)
