RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Summary:  Unable to do PXE install on Intel Patsburg RAID-1 with RHEL6.2

When trying to install RHEL6.2 via PXE on a system with Intel C600 Patsburg RAID-1 configured (RSTe), it adds the RAID md device to the reject list and does not install to the RAID/md device.   While still in anaconda, I can see that the 'isci' driver has been loaded, and 'fdisk -l' shows the /dev/md127 device.  I can manually partition /dev/md127 and create a filesystem.
Looking at the /tmp/storage.log, it appears that anaconda has decided to add the md device to the reject list:
  15:21:38,904 DEBUG   : device 'md127' not in exclusiveDisks
 15:21:38,905 DEBUG   : lvm filter: adding md127 to the reject list
The storage.log and dmesg.log from the PXE session are attached.

The RHEL6.2 install works fine from local media to the same configuration on the same system, which has an Intel S2600CO motherboard.

We noticed the issue below from Fedora, but the suggested kernel parameters did not help in this case.
Please advise whether there is a workaround for this issue in RHEL6.2.

PXE install can have problems with RAID arrays or encrypted devices 
link to this item - Bugzilla: #787744 
When installing Fedora 17 Alpha via PXE, some kernel parameters are not passed which are passed with other installation methods and, with previous releases, were automatically passed on PXE installations as well. These parameters prevent RAID arrays and encrypted partitions from being activated at initramfs initialization time, which interferes with their analysis and/or use by the installer. 
If you are performing a PXE install to a system with RAID devices or LUKS-encrypted partitions, you should add the following kernel parameters to ensure the installer does not encounter problems: rd.luks=0 rd.md=0 rd.dm=0. If you do not, you may encounter an installer crash with an error RuntimeError: device is already mapped, or similar problems.

Comment 3 RHEL Program Management 2012-05-03 05:01:01 UTC 
Since RHEL 6.3 External Beta has begun, and this bug remains
unresolved, it has been rejected as it is not proposed as
exception or blocker.

Red Hat invites you to ask your support representative to
propose this request, if appropriate and relevant, in the
next release of Red Hat Enterprise Linux.
