Description of problem:
When install RHEL5.8 on a IBM x3560M4 which is connected to a SAN storage, it reports "Assertion (head_size <=63) at dos.c263 in function probe_partition_for_geom() failed" during installation.
After removing SAN connection, then installation can work and did not report any error.
Version-Release number of selected component (if applicable):
100% in customer site.
Steps to Reproduce:
1. connect the system to a san storage.
2. install rhel5.8
3. during installation, anaconda would report the error and installation would fail.
Get error during installation and can not install the OS.
Should not get the error.
RHEL6 does not have this issue even if system has SAN connected.
