Hi,
I am using Mellanox MHES18 HCA connecting with Qlogic 9024 unmanaged
switch. Sometime after system reboot I get 1x link width on two ports
between HCA and the switch. The cable is good. It's supposed to be 4x, and
usually after one more system reboot it will go back to 4x. My question
is, can I simply change the port's physical state to polling and let it do
link training again to get 4x link without reset the HCA? Is it possible?
Thanks!
Yicheng Jia
