Diagnosing SAS Data Path Failures on Servers
Using MegaRAID Disk Controllers
Important Operating Note
On Oracle x86 servers using MegaRAID disk controllers, Serial Attached SCSI (SAS) data
path errors can occur. To triage and isolate a data path problem on the SAS disk controller, disk
backplane (DBP), SAS cable, SAS expander, or hard disk drive (HDD), gather and review the
events in the disk controller event log. Classify and analyze all failure events reported by the
disk controller based on the server SAS topology.
To classify a MegaRAID disk controller event, gather and parse the MegaRAID disk controller
event logs either by running the StorCLI command.
For example, manually gather and parse the controller event log by using the StorCLI
command. At the root prompt, type:
root# ./storcli64/c0 show events file=event.log
Controller=0
Status=Success
Note -
Use the existing name of the event log as the name for the disk controller event log. This
produces a MegaRAID controller event log with the given file name event.log.
To show drive and slot errors separately, at the root prompt, type:
root# /opt/MegaRAID/storcli/storcli64 /c0 /eall /sall show errorcounters
Controller=0
Status=Success
Description=Show Drive/Cable Error Counters Succeeded.
Error Counters:
