Problems booting off CDROM drive

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

Re: Problems booting off CDROM drive

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.

Re: Problems booting off CDROM drive

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?

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...

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?

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

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