Adding new Disk attached from SAN with out reboot.?
In the sum of all things, downtime is not yummy. I am searching for a way to detect SAN attached disk. I have tried going and running kudzu on the box with no luck as well as going into LVM and running lvmscandisk. I am using Redhat 40 update 1. I am attached to a EMC san .
Any advice or tips would be great!
I am aware of unloading / loading the fiber driver as well, only problem with that is if I have a DB up attached to the SAN , loadling and unloading that driver would be bad.
Thanks for everyones time upfront !!
