HW path for root disk ?

[mobidyc]

Hi,

I'm writing a shell script for autoinstall HP-UX through Ignite configuration files.

Could you help me to discover the HW path of the root disk by model ?

I've found the following informations in my environments:
MODEL / HWPath
BL860c 0/2/1/0.0.0.0.0
J6000 10/0/15/1.6.0
rx1620 0/1/1/0.0.0
rx2620 0/1/1/0.0.0
rx4640 0/1/1/0.0.0

Thanks for your help

Shalom,

lvlnboot -v

Notice the rx servers root disk is the same by default on all three of those.

It is sometimes hard to find this information if the servers are not up and running.

Anyway, the path is fixed for most servers.

Example:

BL860c

0/2/1/0.0.0.0.0 (left slot)
0/2/1/0.0.0.1.0 (right slot)

But it could be different, if you are using hardware based RAIDs and/or optinal smartarray controllers!

You could also refer to below url to understand the H/W path

http://docs.hp.com/en/B2355-90675/ch01s05.html

There are some special features for many servers, another of these features

rx4640

0/1/1/0.1.0 (top slot)

0/1/1/0.0.0 (bottom slot in simplex config.)

0/1/1/1.0.0 (bottom slot in duplex config.)

Hi,

steven => i know how to find the root disk of my servers, it's not the question.

Avinash V Rao => Understanding the HWpath will not help me.

Torsten => i only search the HW path for a base system, no additional controller.

do you have any system not in my list ?
could you indicate the root disk please ?

the idea is to have a listing for use in the shell script i'm writing.

Thanks,
Regards

Hi Cedrick:

For what its worth:

rx2660 0/1/1/0.0.0.1.0

Be careful, many servers have 2 or more internal disks - all can be used for the OS **OR** data!
There is no default disk for the OS, you can also install the OS on external disks and use the internal for data.

Keep this in mind while scripting.

Anyway, for each server you can find this information in the (install or user) guide.

This documents lists the pathes (page 54 ++) for many rx and rp servers from 8xxx and 7xxx family:

Do you need the pathes for some specific servers?

hi


On the rx systems please try
#dmesg | grep -i boot


this shall show the disk from which the currect disk has boted.

Alteranatively also can try if the system has the boot disks set properly as

#setboot | grep -i primary
#setboot | grep -i alternate

Torsten:

I want to install all servers on the first system disk by default but it will be possible, of course, to confirm/modify this choice.

i've no specific server in mind but I try to have an exhaustive list.

I will search through docs.hp.com, thanks for the pdf.
