Can't boot off external DVD

[Aaron Pancoast]

I'm trying upgrade my test HP server and when I boot into single user mode, and SEArch the DVD isn't there. The hdd are there though. I can boot into multiuser and mount the DVD and umount and do whatever I need to, but I can't do anything in single user mode. Is there something that I'm over looking.

May by, the DVD is connected via controller which requires a special SW in order to work. Try to connect the DVD to a built-in SCSI.

did you try to do search all at BCH? If not, try that and see if it shows all devices hooked to it and make sure that power turned on for DVD.

[Aaron Pancoast]

the DVD is connected to an LVD controller.

I did an SEA, but didn't specify ALL, is there a difference

[IT_2007]

what type of HP-UX server is it? sometimes it helps you when you do search all instead of SEA only.

[Aaron Pancoast]

HP-UX L-class server. I'm going to give it a try in a few min. I will keep you posted. Thanks.

[Aaron Pancoast]

Unfortunately, that isn't going to work, because it doesn't offer the ALL command for SEA.

[IT_2007]

sorry. I didn't know that you are using L class. Only new machines offer sea all options. When you do sea what output are you getting? Are you sure that DVD is hooked up and seated properly? Also you can try to power off and change connection to local SCSI port.

The only devices that come up are the hard drives P0-P3, and I know the DVD works, because I can use it in multi-user. Is there any SW that would prevent the DVD from being recognized in single user or the ability to boot off the hardware path which is 0/1/1/0.1.0

[IT_2007]

May be firmware is not able to recognize it.

DVD also shows as random access media and it won't show as DVD media, are you sure that P0, P1, P2 and P3 devices are Hard disks? Check the actual Hardware path.

[A. Clay Stephenson]

HP boxes are rather picky about what devices can be used as boot devices because the firmware may not recognize them. If this is an HP supplied DVD then look for and install the latest Hardware Enablement patches or the latest firmware for your L-box model. The HWe patches are supplied as part of your periodic patch bundle CD's.
