Hard Drive failures
Recently we have had issues with Hard drive failures on a few 6900 devices. I was just curious if anyone else is experiencing similar issues and what you were doing to monitor and alert for those failures.
I am able to pick up some of the errors in syslog but am not sure if all of the errors are hitting my syslog.
Thanks

- I haven't heard of any significant numbers of drive failures on 6900 units. I expect that any drive failures would be logged locally and via syslog if you have it configured. Are you seeing intermittent syslog delivery?
- I do have sysloging configure. I wasn't sure if all of the errors would be sent to syslog. If they are I was curious if anyone worked out what all of the possile events being logged would be. I was trying to configure some filters for alerting that would capture the correct events.
- These are hard drives and not compact flash storage you are referring to? I ask because I ran into a wierd bug a few months ago upgrading to 10.2. The upgrade set my compact flash storage as swap. Didn't catch it until a couple months later, but continued use as swap would likely result in premature failure.
- Yes it is the hard drive. We saw the same issue and made the change documented in sol12170. Sometime after that was when we started experiencing the hard disk issues.
- Cool. I was advised by support (and it does make sense) that swap file on compact flash would affect performance and could result in shortened life of the flash. I had some performance issues with ASM running on the same box and it was suggested as a contributing factor.
- I'm on my 5th HD failure in 9 months on 6900s/8900s. First time, support asked me to RMA the drive. Second one, they asked me to RMA the entire box. Still waiting to see what happens this time.
- I'd be checking the quality of the power going to the units and making sure there aren't any ventilation issues. Sure sounds like something external is a factor to me.
- Good point I can double check power and ventilation but I think its OK..
- Hah...they had me do both Power Supplies and both HDs in one of my units as well, along with a clean install. Definitely no power/ventilation issues on our side either.
- I would check the Drive manufacturer, Seagate had a lot of issues with SATA drives in 2009, early 2010 time frame.
