Solutionioscan -nfCdisk
and note the HW path of the CDROM device
otherwise you can interrupt the boot sequence when there appears the message ".. to interrupt .. press any key.."
Then you can search for bootable devices at GSP by
SEarch
When you have identified the HW path the CD device is connected to
issue
BOot X/X.X.X

Re: Booting from CDrom
Did you not get any information about disk types (for example: SEAGATExxxx,TOSHIBAyyyy) ?

Re: Booting from CDrom
Likely it will give you the path on the second line, like /dev/dsk/c2t3d0, but it will give you at least the H/W path:
i.e. 14/0/2.3.0
Once you know the path, you can reboot from CD. Interrupt the bootsequence; enter ISL.
Type 'env' to see the settings.
Then:
ISL>rootdev=disc(14/0/2.3.0;0)INSTALL
ISL>kernel=INSTALL
ISL>go

Re: Booting from CDrom
Obviously, the easiest method is to note the hardware path before booting. If it's too late for that, you have to make some (semi-)educated guesses, using the SEArch command to look for sequential access devices (rather than random). Hopefully you can narrow it down.

Re: Booting from CDrom
Boot the box and interrupt the boot...
Main Menu: Enter command or menu > sea
Searching for potential boot device(s)
This may take several minutes.
To discontinue search, press any key (termination may not be immediate).
Path# Device Path (dec) Device Path (mnem) Device Type
----- ----------------- ------------------ -----------
P0 0/0/1/0.3 extscsi.3 Sequential access media
P1 0/0/1/1.2 intscsib.2 Random access media
P2 0/0/1/1.0 intscsib.0 Random access media
P3 0/0/2/0.2 intscsia.2 Random access media
P4 0/0/2/0.0 intscsia.0 Random access media
P5 0/0/2/1.2 media.2 Random access media
P6 0/2/0/0.0 Random access media
P7 0/2/0/0.0.1 Random access media
P8 0/2/0/0.0.2 Random access media
P9 0/2/0/0.0.3 Random access media
P10 0/3/0/0.1 Random access media
P11 0/3/0/0.1.1 Random access media
P12 0/3/0/0.1.2 Random access media
P13 0/3/0/0.1.3 Random access media
Main Menu: Enter command or menu > bo p5
...as p5 / media.2 is the DVD-ROM.
A caveat.....
We have 4 L2000's here, and they all behave the same. Following a HARD poweroff from the actual server, the SEA shows the DVD and all is well.
IF you then issue a RESET or an RS from the GSP, the DVD IS NOT properly detected. The media.2 designator is not present, and BO P5 results in an error. The box must be hard powered off and on again to properly detect the DVD. I don't understand it, but it's repeatable behaviour, so there you go.

Re: Booting from CDrom
I could have sworn that your DVD would show up as a sequential device. Obviously I was mistaken - thanks.

Re: Booting from CDrom
1. before shutting down run command
# lvlnboot -v
It is going to show you the boot hard disks like this:
Boot Definitions for Volume Group /dev/vg00:
Physical Volumes belonging in Root Volume Group:
/dev/dsk/c1t2d0 (0/0/1/1.2.0) -- Boot Disk
/dev/dsk/c2t2d0 (0/0/2/0.2.0) -- Boot Disk
Then try This command
# ioscan -kfCdisk|grep ROM
it will show hardware path for your DVD .. like this:
disk 0 0/0/1/0.2.0 sdisk CLAIMED DEVICE HP DVD-ROM 3
05
Then reboot the server and interrupt boot process. At the command menu prompt you can again run a search to fing your bootable DVD. Put the bootable disk in drive and run command at the menu
> sea ipl
This will show you all bootable devices.
Once you get the prompt back then type
boot < the hardware address >
for my case it is 0/0/1/0.2.0
For loading OS you may say no to interact ipl question.
Good luck,
Mainak
