Error description
- Linkup between the 8Gb QLogic FC adapter and the 16Gb Brocade Flex switch module may fail when the Brocade switch is set to a speed setting other than 'auto'. - Link bounces on the internal or external ports of the 16Gb Brocade AG switch may cause path failures or very long path failover times.
Local fix
Problem summary
- Linkup between the 8Gb QLogic FC adapter and the 16Gb Brocade Flex switch module may fail when the Brocade switch is set to a speed setting other than 'auto'. - Link bounces on the internal or external ports of the 16Gb Brocade AG switch may cause path failures or very long path failover times. - fcstat application running during link bounce events may hang.
Problem conclusion
- Modify linkup auto-negotiation logic to use adapter NVRAM hints on the best topology settings for linkup operations. - Modify FC protocol driver async event assumptions to avoid waiting too long for an adapter RESUME event that will never arrive. - Modify adapter driver to abort timers waiting for events after back-to-back link bounces. - Improve handling of FLOGI timeout when trying to enable the adapter firmware virtual port (VP) associated with the physical connection. - Fix race condition between sleep and wakeup of ioctl calls for NDD_CHBA_DATA and NDD_RNID_DATA, both associated with fcstat. This may cause fcstat to hang.
Temporary fix
