Re: [dm-devel] Rescan for new LUNs



That sounds more like what I am looking for. But I can not find the script on my system or what provides it via "yum provides". I am running RHEL 5.5.
 
We have customers that run an Application that needs to be up 24*7. They some times need to add additional storage and when attached to a SAN they would prefer not to have to take the Application down and reboot the system just to make the new LUNs be seen by the system.

It's not an easy process.

The rescan-scsi-bus.sh script was added in recent RHEL5 updates, already in old SLES. I guess it's becoming kind of a standard.

Hello:
        What is the best way to cause the system to rescan for new LUNs, other than rebooting?
