echo "1" > /sys/class/fc_host/host0/issue_lip
echo "- - -" > /sys/class/scsi_host/host0/scan
echo "1" > /sys/class/fc_host/host1/issue_lip
echo "- - -" > /sys/class/scsi_host/host1/scan
where host0 and host1 represent your HBA id's

you could also make use of the tools/utlities from the HBA vendor.

A very handy Linux-based solution xref-ing many other solutions (including rescanning), is: emc93760. Also, the "Linux Host Connectivity" guide and the OS vendor, are other avenues to pursue..

I see only RHEL 5.0 in this list from Five series. What about 5.1 till 5.5? I guess only this link/solution is not updated..

Hi SKT.. You are absolutely right.. There are items and areas that may not be up to date and alot of links to follow as well. Some of these may help in other ways too, but I will bring it up to the author. I would reach out to the OS vendor or even check the "Linux Host Connectivity guide" - which is more frequently updated, because there are multiple recan steps provided in this document. Hope this helps and thanks for your input.
