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.

Description Justin Clift 2010-04-28 01:38:37 UTC 
Description of problem:

Just attempted to use Infiniband SDP mode in DRBD 8.3.x, and was unpleasantly surprised to find the SDP library is not present in RHEL 6.

It is in RHEL 5, as libsdp, so this seems pretty non-optimal.


Version-Release number of selected component (if applicable):


How reproducible:

Always.


Steps to Reproduce:
1. Try to use an SDP enabled application (fail).
2. Look for libsdp using yum (fail).
3. Verify it is present in the base package set for RHEL 5.
  
Actual results:

Missing Infiniband library.

Expected results:

Library to be present, in order to use SDP mode in applications.

Additional info:

Pretty sure "infiniband-diags" isn't the exact the correct component name here, but it's related to the right people should get this.
Comment 2 RHEL Program Management 2010-04-28 03:15:21 UTC 
This request was evaluated by Red Hat Product Management for inclusion in a Red
Hat Enterprise Linux major release.  Product Management has requested further
review of this request by Red Hat Engineering, for potential inclusion in a Red
Hat Enterprise Linux Major release.  This request is not yet committed for
inclusion.
Comment 3 Doug Ledford 2010-04-28 18:30:31 UTC 
Both the SDP kernel module and libsdp were always a stop-gap measure to allow applications to realize some of the performance benefit of RDMA networks before they were actually rewritten to utilize RDMA transfers natively.  It's been well over 3 years since native RDMA APIs made their way into Red Hat Enterprise Linux, and the applications that most needed to be ported to RDMA APIs have been.  In addition, the IPoIB support in Red Hat Enterprise Linux has been updated to support connected mode on IPoIB interfaces with large MTU sizes.  With the IPoIB interface in this mode, most of the performance benefit of SDP mode is realized in base TCP mode.  So, since the SDP protocol has never and will never be a part of the upstream Linux kernel, and since IPoIB can now provide most of the performance benefit that SDP used to provide, SDP and libsdp have been removed from our distribution.

Cool, no worries.  Hope that goes in the Release Notes. :)
