Looking to shed a little more light on a suspected hard drive issue. DataCenter Engineer said the F5 LTM has a blighting light complaining about a hard drive failure. I don't show anything on the system (unless I'm looking in the wrong place) Can someone direct me to some useful documentation to help determine if there is a hard drive problem. Thanks for the help!

You could check /var/log/ltm for bad sector or other HDD related errors. Or you could run the End User Diagnostic to check definitively. Aaron

have u checked /var/log/kern.log? hdd error is usually shown there. additionally, eud may not contain fsck. it depends on what eud version u r using. sol11664: Change in Behavior: Removal of File System Check from the EUD http://support.f5.com/kb/en-us/solutions/public/11000/600/sol11664.html hth

Thanks! I will run the EUD tonight on the unit.

Yes EDU will help you to find out where the problem exactly is....

Can a filesystem check be performed remotely or does it require you to connected to via console in single user mode?

Only in single user mode as the drive needs to be unmounted:

Can someone explain what the "undefined" indicates?

Sys::Raid::Disk

Name Serial Number Array Member Array Status

------------------------------------------------------

CF1 CB06537260500900RY05 no undefined

HD1 WD-WCAT1E936493 yes ok

HD2 WD-WCAT1E937650 yes ok

Running v10.1.0

That's just showing that there isn't a RAID array defined for the compact flash. I see the same thing on a working 8900:

Sys::Raid::Disk Name Serial Number Array Member Array Status ------------------------------------------------------ CF1 B85131BGBCR209131600 no undefined HD1 WD-WCAT18687337 yes ok HD2 WD-WCAT18687750 yes ok

Which platform is this? Have you seen SOL12170:

sol12170: The BIG-IP system may use the CompactFlash card for the swap partition on some platforms

http://support.f5.com/kb/en-us/solutions/public/12000/100/sol12170.html

You could force an disk check following SOL10328. You might also try running qkview and uploading the tech.out to http://ihealth.f5.com to review the suggestions there. If you don't get anything useful there, you could open a case with F5 Support.
