Security Analytics appliances that are connected to external storage sometimes will use HBA cards or fiber channel cards. Security Analytics servers usually have two of these HBA cards for redundancy. These ports should be monitored and can show Offline if there is a connection problem.
Dell R630 connected to a Dell MD3860 or a NetApp E5600 usually with a Brocade switch in the middle.
This can be caused by either a faulty hardware device or one of the following devices not being securely plugged in or seated.
Run the following command (as root) to determine if one of the ports really is showing Offline:
The output should show 4 results:
If any show Offline, check the cables connected to that specific port and reseat them or swap out the fiber cable with a known good one. Also, reseat the HBA adapter cards in the head unit. This will need to be done while the system is powered off. Reseat the SFP modules.
If a Brocade switch is involved, you can run the command "portshow" to see if one of the ports is showing "No_Light" or "Offline" next to portPhys
If the port(s) are still showing as Offline, contact technical support for further troubleshooting.
