Description IBM Bug Proxy 2010-09-13 18:02:45 UTC
1. Feature Overview:
Feature Id: [67054]
a. Name of Feature: [6.1 FEAT] HBA API Completion - library part
b. Feature Description
This feature extends the previous version of libzfcphbaapi (2.0). libzfcphbaapi is an implementation
of the standard HBA API (see t11.org) for the System z FCP host bus adapter. There have been two
major additions in the following areas:
??? FCP pass-through support: it is possible to construct CT (Common Transport for Generic Services,
see document "Fibre Channel Generic Services" available at t11.org) and ELS (Extended Link Services,
see document "Fibre Channel Link Services" available at t11.org) frames in the userspace and send
them into the SAN now. Please note that while it is possible to construct any CT frame, the ELS
requests are predefined. Currently the only supported ELS request is "Request Node Identification Data".
??? event support: events occuring in the SAN can be retrieved now.

This is the library part. There is a dependent kernel part which is tracked by different feature

2. Feature Details:

Hello John,
this will be part of HBA API library and be provided as a backport to existing
RHEL 6.0 version.
It is upstream with libzfcphbaapi 2.1

Unfortunately through the mirroring this information got lost. I have updated
the component here directly.

I have created a tracker for zfcp hba api requests (kernel+library):

Comment 4 Hendrik Brueckner 2010-11-18 14:02:15 UTC
Petr, Dan,

I think the libzfcphbaapi lib is a subpackage of the s390utils, so adding Dan to CC.  Dan, this feature bug is about upgrading the lib to version 2.1 which is available on the developerWorks website.

Thanks and regards,

Comment 5 Dan Horák 2010-11-18 14:36:22 UTC
switching to s390utils that carry the vendor library

Comment 8 John Jarvis 2010-12-01 14:37:46 UTC
This enhancement request was evaluated by the full Red Hat Enterprise Linux 
team for inclusion in a Red Hat Enterprise Linux minor release.   As a 
result of this evaluation, Red Hat has tentatively approved inclusion of 
this feature in the next Red Hat Enterprise Linux Update minor release.   
While it is a goal to include this enhancement in the next minor release 
of Red Hat Enterprise Linux, the enhancement is not yet committed for 
inclusion in the next minor release pending the next phase of actual 
code integration and successful Red Hat and partner testing.

Just got confirmation per mail from John
- Red Hat approved to enhance the version of the library from 2.0 to 2.1

Since the only diff from libzfcphbaapi version 2.0 to 2.1 is the code for the R 6.1  feature request it is useless to backport that code
