timeout Warning

14:43:01 kapila unix: WARNING: /io-unit@f,e0200000/sbi@0,0/SUNW,socal@2,0/sf@1,0/ssd@0,0 (ssd10):

Nov 12 14:43:01 kapila unix:    SCSI transport failed: reason 'timeout': retrying command

This command is retried and normal operations continue. Sometimes the timeout may be accompanied by a loop reset (see OFFLINE/ONLINE sequences).These events are normal and are no cause for alarm unless they occur at a rate greater than five times per 24 hours. No data is lost or corrupted and commands are completed on subsequent retry.

Fibre Channel Loops are specified to have a bit error rate (BER) less than 10E-12. Actual BER is better than 10E-13 and may be as clean as 10E-15.However, you can occasionally experience a bit error that results in a corrupted frame. As corrupted frames are discarded, the end result will be a command that fails to complete and which eventually gets timed out by the ssd driver. A warning indicating a command timeout is generated to the console.
