Bug 467713

+++ 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/ ?

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.
