Interpretting 3Ware error messages

[Doug Poland]

Hello,

I have a 7.2-R i386 system running a 3ware 9500S-4LP SATA 150
controller with 4 SATA drives.  I recently starting seeing the
following in my logs....

smartd[906]: Device: /dev/twa0 [3ware_disk_00], 1 Currently unreadable
(pending) sectors
smartd[906]: Device: /dev/twa0 [3ware_disk_00], 1 Offline
uncorrectable sectors

Using the twi_cli program, I can examine the disk subsystem, but I do
not see any issues with an underlying drive.

I suspect a disk problem, but cannot identify the individual disk or
the nature of the problem.  Can anyone shed some light on this?
