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/ ?

Exactly. 

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

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).

The RHEL 5.4 bug for this issue can be found at bug 467201.

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.
