Bug Description
== Comment: #0 - Haren Myneni <email address hidden> - 2015-01-07 21:34:09 ==
---Problem Description---
Using preseed partman/
After some time, the dmesg shows the kernel found other disks. we are seeing the same behavior even with kernel parameter 'scsi_mod.
So with this issue, user can not select some disks with automated installation.
Contact Information = <email address hidden>
---uname output---
14.10 release
Machine Type = Any power system with more disks
---Debugger---
A debugger is not configured
---Steps to Reproduce---
Select system which has more disks. Select last disk in automated installation
Install method: NFS
Install disk info: SDD
Install ISO Information: Ubuntu Utopia

preseed file:
d-i partman/
mkdir /tmp/updates; cd /tmp/updates; \
wget -o /tmp/wget_log http://
tar zxvf preload_
/bin/sh /tmp/updates/
DISKA=; \
debconf-set partman-auto/disk "$DISKA";
We execute ipcronfig comamnd as part of pre.sh. As we see in the log file, only disks sda-sdf are listed.

It is not the issue of not recognizing some disks. As you see in the final dmesg output, all disks are probed and recognized. But the issue here is only few are probed before the installer started. So the problem is why the installer started before probing all storage devices.

As mentioned in the bug description, first dmesg was collected at the time of partman/
We collected the final dmesg later when we noticed the the failure. The final dmesg shows all expected disks sda- sdl are probed and we verified with iprconfig command.
So this issue could be timing of starting the installer before all devices are probed. We should expect that the kernel boot should be completed and then the installer should start.
