Re: Installation - boot after installation fails



p.s. disk types tried: logical volume from a vgClient volume group, iSCSI LUN (virtual "physical" disk).

sizes: 10G and 12G (I regularly install AIX on 4 and 6G "disks").

4 to 5 years ago I was only able to get Linux to boot, (Redhat, Novell, Debian) unless it was a physical disk. I have not tried that yet because I do not have an empty disk to supply. And if that worked I would just uninstall it as that is "too expensive" in terms of resources.

I have tried the "install64/export64" options Guided LVM (and I choose as many partitions as possible) and the Guided "one partition" - recommended for new users option.

The partitions are created, the install runs fine, but on reboot - nada.

Welcome to yaboot version 1.3.13
Enter "help" to get some basic usage information
boot: Linux

Please wait, loading kernel...
Can't open device </vdevice/v-scsi@30000002/@1:0>
/vdevice/v-scsi@30000002/@1:2,/boot/vmlinux: Unable to open file, Invalid device
boot: help

Press the tab key for a list of defined images.
The label marked with a "*" is is the default image, press <return> to boot it.

To boot any other label simply type its name and press <return>.

To boot a kernel image which is not defined in the yaboot configuration
file, enter the kernel image name as [[device:][partno],]/path, where
"device:" is the OpenFirmware device path to the disk the image
resides on, and "partno" is the partition number the image resides on.
Note that the comma (,) is only required if you specify an OpenFirmware
device, if you only specify a filename you should not start it with a ","


If you omit "device:" and "partno" yaboot will use the values of
"device=" and "partition=" in yaboot.conf, right now those are set to:
device=/vdevice/v-scsi@30000002/@1
partition=2

boot:



That is all I get. I am willing to spend some time on this - but I do not know the "Linux" way these days.
Clear instructions, clear requests for info (e.g., if you can jump out of the install and look at something, manual divvy if you prefer, etc..)

just might be a few hours to days between responses as I also have regular work to attend to.

Thanks!!! for your assistance!

i'd probably start with the guided partitioning and modify from
there to your own needs. A bootable setup looks like this in my
case, with sda2 being "/":

    host:/# sfdisk -l
    Disk /dev/sda: 36864 cylinders, 64 heads, 32 sectors/track
    Warning: The partition table looks like it was made
      for C/H/S=*/255/63 (instead of 36864/64/32).
    For this listing I'll assume that geometry.
    Units = cylinders of 8225280 bytes, blocks of 1024 bytes, counting from 0

       Device Boot Start     End   #cyls    #blocks   Id  System
    /dev/sda1   *      0+      0       1-      8001   41  PPC PReP Boot
    /dev/sda2          1     122     122     979965   83  Linux
    /dev/sda3        123    4698    4576   36756720   8e  Linux LVM
    /dev/sda4          0       -       0          0    0  Empty

Is yours a LPARed environment with disks mapped from VIO servers,
or are the disks real physical ones?

Best regards,
