Logs from installation.
Description of problem:
Steps to reproduce:
1. Create two volumes in OROM on same set of HDDs (i.e. 1st RAID1 (50GB) 2nd RAID1 [rest of capacity])
2. Clear MBR sectors of both volumes (i.e. using dd if=/dev/zero of=/dev/mapper/volume_name bs=512 count=1)
3. Write md5sum of this 512 bytes sectors of first volume (i.e. dd if=/dev/mapper/volume_name of=tmp bs=512 count=1; md5sum tmp)
4. Install Red Hat Enterprise Linux 5.4 alpha on second volume.
5. Verify that OS will not boot from 2nd volume
6. Verify that md5sum of first 512 bytes of first was changed
There should be no changes on MBR of first volume. OS should correctly boot from 2nd volume.
Booting process hang up when bootloader should be run. First 512 bytes sector on first volume is changed.
See attached files.
