And the rescan-scsi-bus.sh script. If the server is HP, you can try the hp_rescan command.
Post your results.

Re: qlogic HBA rescan
Unfortunately, the "issue_lip" does indeed interrupt IO on my other active LUNs on this host for ~10-15 seconds, which is unacceptable in my environment.
Do you or anyone else know of a method to rescan without IO interruption? These are HP servers (EMC storage), but the version of hp_rescan I've got uses the /proc method as well, and as such is obsolete (I've tried it and it doesn't seem to do much of anything). Can you point me to the latest version? I would certainly give it a shot.
Thanks!

You will see that the /proc is still a valid method.

SolutionHP has a utility caled hp_rescan that is in the hp-fibreutils package in the Linux PSP. The current PSP doesn't have a version that will install on RHEL5, but there is a version posted that is for RHEL5. This works with both QLogic and Emulex HBA's. The latest version is
Linux inbox driver enablement kits for QLogic HBAs and mezzanine cards
http://h20000.www2.hp.com/bizsupport/TechSupport/SoftwareDescription.jsp?lang=en&cc=us&swItem=co-69719-1&jumpid=reg_R1002_USEN
The hp_rescan utility is in the fibreutils-3.0-3 rpm file
hp_rescan -h will give you the syntax and options for use.
