RE: How to constrain the install through kickstart to one drive

Unfortunately, I'm at a loss. The environment I'm in is all SCSI disks
on hardware raid controllers. I would guess that libata is the ATA
driver. Looking in /proc/partitions though I can see all the partitions
on the disks that the OS can see.

/proc # cat partitions
major minor #blocks name

104 0 35565360 cciss/c0d0
104 1 104391 cciss/c0d0p1
104 2 2096482 cciss/c0d0p2
104 3 5245222 cciss/c0d0p3
104 4 1 cciss/c0d0p4
104 5 5245191 cciss/c0d0p5
104 6 20772013 cciss/c0d0p6
104 7 2096451 cciss/c0d0p7
104 16 35565360 cciss/c0d1

On my virtual systems, I can see the following:
# cat /proc/partitions
major minor #blocks name rio rmerge rsect ruse wio wmerge wsect
wuse running use aveq

8 0 17825792 sda 21808 13601 274314 65860 223847 214442 3515998

On the other hand, lsmod shows the cciss module on my physicals and
either the Buslogic or mptscsi driver on my virtuals. That's what I use
to make my determination in the %pre section.

In thinking about this some more, /proc/partitions might be a better way
to determine which drive to partition and how since you are shown all
the drives and partitions that the OS can see (column 4) as well as
their block size (1K blocks) (column 3).

Thanks Maarten,

Just curious now... I did an lsmod on 2 machines. On one I see the ahci
and
the libata modules loaded. I don't see these on a machine with IDE
drives
installed. Am I to assume these are the modules for SATA/PATA? If so,
good.
I did not see anything that stood out to me indicating a module for IDE
disks
on the IDE only machine with lsmod. Would you know what module I should
be
looking for?

Thanks in advance,

Phil

If you always know that the drive you want to install on is /dev/sda,

machines
have their drives addressed in different ways (/dev/hda, /dev/sda,
etc).
In those cases you can still use a single ks file be creative use of
the
%pre section to determine the correct disk name to clear and
partition.

I use a single ks file for each RHEL (one for RHEL3, one for RHEL4,
etc)
regardless of whether I'm installing on a physical machine
(/dev/cciss/c0d0) or virtual machine (/dev/sda) by checking the loaded
modules (lsmod) in the %pre section and then changing the partition
table accordingly. This also lets me address different drive sizes in
different ways.

On the other hand, the kickstart files become a bit more complicated
and
the chance of errors in the kickstart file go up, but it is possible.
The use of multiple kickstart files also depends on the application
loadout of the systems you're installing on. If all the systems get
the
same package load, then one kickstart file is easy to maintain. If
different servers get different loads, then it's much easier to manage
that with multiple kickstart files.

Thanks for responding both Andrew and Maarten.

Ok then, I was hoping that there was a way to say, regardless of what
drives
are installed in the pc, just load the drive that's hanging off
Primary
Master and leave the rest alone? This is basically what I want to do.
I
just didn't want to go through the pc's to find out exactly what type
of

drives are installed. Not to start an OS flame war but I can do this
in

Solaris using the keyword "bootdisk" in the jumpstart profile. Just
wondering if there was something similar in ES4.

Thank you again, for your time...

You can't always use one size fits all. We have many kickstart
files
for our many servers. Each kickstart is tailored for a type of
server
and we use the type that best suits our needs.

So, the ondisk=sda/hda problem is solved by using the appropriate
kickstart file. At the install screen we define which kickstart to

use

with "linux ks=kickstart_file_name".

HI All,

I have a number of machines I would like to install using
kickstart.

This isn't the problem as this I know how to do...but, some pc's

have

more than one HD installed. Some of the pc's have pata, sata or
ide
drives; that is a mixture of all I have mentioned. In order to

combat

the problem of kickstart not working on all types of disks, I took

out

the ondisk=[s|h]da. This works well on a pc with a single disk.

With

more than one disk, the second disk also get a filesystem. I
don't

want

the second disk touched at all. Is there a way to do this?

Thanks in advance,

Phil
