I have an openE SAN with a 3ware 9650SE-24M8 Raid controller.  The disk are configure in RAID-6 with 1 out spare.  I receive an drive time out error form the 3ware controller.  The disk seems to be active like the others.  In the unit information tab, the unit status is OK with a *.  Do I need to replace the drive or rebuilt it or just do nothing?

Root cause is at least one (more likely several contiguous bad blocks on a HDD).   No reason to worry unless this starts getting more frequent.  The nice thing about R5 and R6 is that the controller will automatically remap the bad block and write it with the correct data extrapolated from the XOR parity

So don't worry about it.   Best practice, if you have not already done so is to make sure the system is set up for regular consistency/check rebuilds.  This will correct such errors.
