Description Andrius Benokraitis 2008-10-20 13:38:22 UTC
+++ This bug was initially created as a clone of Bug #467201 +++

Feature request:
Dynamic SCSI rescan functionality can be currently implemented by manually echoing values into the SCSI sysfs files. This is an extremely useful feature in enterprise scenarios, as a reload of the underlying driver(which does a SCSI rescan) is not practical as it is disruptive.

It would be ideal if the RHEL kernel provides a bundled SCSI rescan script which performs the following dynamic SCSI rescan functionalities:

1) Detect luns added to the host.

2) Remove luns from the host.

3) Resize existing luns on the host.


Version-Release number of selected component (if applicable):
RHEL 5.3.

Are you looking for something like the rescan-scsi-bus.sh script from http://www.garloff.de/kurt/linux/scsidev/ ?

--- Additional comment from marting@netapp.com on 2008-10-16 07:39:56 EDT ---

Exactly. 

This could be made a part of the sg3_utils package. Are there any plans to include this in future RHEL kernels?

--- Additional comment from dhorak@redhat.com on 2008-10-16 08:39:04 EDT ---

Please submit a request for enhancement via the standard support channel and let them bind the request with this bug.

I can add the script into Fedora on my own, so it will then appear in RHEL 6.

Dan - NetApp is a formal engineering Partner and therefore this bugzilla will serve as the official feature request I'll monitor (being their assigned partner manager).

Comment 1 Andrius Benokraitis 2008-10-20 13:40:43 UTC
The RHEL 5.4 bug for this issue can be found at bug 467201.

Comment 2 Dan Horák 2008-11-03 08:08:10 UTC
I have cloned this bug for Fedora Rawhide and made it block this bug. Dependency on the RHEL 5.4 original bug (auto created during cloning) is removed.

Comment 3 Dan Horák 2009-03-19 13:43:49 UTC
since sg3_utils-1.26-2.fc10 in Fedora

Comment 4 releng-rhel@redhat.com 2009-11-02 23:13:51 UTC
Fixed in 'sg3_utils-1.26-2.fc10'. 'sg3_utils-1.27-2.el6' included in compose 'RHEL6.0-20091102.0'.
Moving to ON_QA.

Comment 6 Dan Horák 2010-08-17 10:08:19 UTC
Michal, NetApp feedback is tracked in bug #538787

Comment 8 Ronald Pacheco 2010-09-23 18:07:58 UTC
NetApp has verified bug 538787, so marking this one as verified, too.

Comment 9 releng-rhel@redhat.com 2010-11-11 14:58:43 UTC
Red Hat Enterprise Linux 6.0 is now available and should resolve
the problem described in this bug report. This report is therefore being closed
with a resolution of CURRENTRELEASE. You may reopen this bug report if the
solution does not work for you.
