I am confused about my R620 iDrac. Its not working now but from previous last year it was working fine. I don't when i checked its logs i saw that its license expired. How a enterprise license can be expire.  Currently iDRAC state is:-> idrac port light not up -> setting is accessible but in logs they that license is expired. Now i just wanted to know that can i use my exported license from my other server in this R620? Can a single license used on multiple server?or what would be above problem solution?Any Suggestion or solution?Thanks in Advance..
