Symptoms


Oracle ZFS Storage Appliance head BUI shows the Infiniband port is connecting at 2GB/s.


The customer may also complain about performance on Infiniband connections being slow.


 


From the CLI view:


Head1:> configuration net devices
Head1:configuration net devices> show
Devices:
DEVICE UP SPEED MAC
ibp0 true 2000 Mbit/s not available        <<<<<<<< 2G
ibp1 true 2000 Mbit/s not available        <<<<<<<< 2G


 


Cause


We can check using the command line outputs from 'IBstat', that the actual speed is: 40G




Head1:configuration net devices> confirm shell IBstat


Port 1:
State: Active
Physical state: LinkUp
Rate: 40                <<<<<<<< 40G


Port 2:
State: Active
Physical state: LinkUp
Rate: 40                <<<<<<<< 40G




If the link speed is OK (40GB), then it is unlikely to be a hardware issue.


 


Solution


If the link speed is unknown or Rate:2  ... then replace the IB card.


 


If the link speed is correct, then please upgrade to Appliance Firmware Release 2013.1 Update 5.2 which contains the fix for this issue.
