HBA Speed Issue

Solution Verified - Updated -

Issue

  • 2 HBA's are active on the server, connected with the same switch model where auto-negotiation is set with SAN switch at 2Gbps. But one of the HBA's shows the speed is 1Gbps, other one is good i.e 2Gbps.
    We would like to know the cause and it is to be active at 2Gbps.

  • Below are the details:

# cat /sys/class/fc_host/host0/speed
1 Gbit
#cat /sys/class/fc_host/host1/speed
2 Gbit

Environment

  • Red Hat Enterprise Linux(RHEL)
