HBA Link Speed Validation


Go to solution Solved by JorgeB,

Recommended Posts

I just installed a new 9300 HBA in my server. I had found a command that can be run from the command line that will output the link speed of the HBA to ensure its connection is not degraded. But i dont seem to be able to locate that forum. It helped me find out that my oboard SAS was running a degraded link, was hoping to ensure thats not the ase now

 

Output looked something like this:

# fcinfo hba-port

I found the command, but I am still seeing a downgraded rating. Any suggestions?
