No I didn't. It was original setup. 2.) are you sure the drive is failing? Does the problem only affect this drive or are other drives randomly affect too? If you've run 'zpool clear' and the problem comes back, something is wrong but it could also be RAM, CPU, motherboard, controller, or power supply problems. Smartmontools can read the drive SMART data and device error logs...run it from an Ubuntu 10.04 Live CD (sudo apt-get install smartmontools) or from a PartedMagic Live CD if you have trouble getting Smartmontools working on OpenSolaris with your hardware. No I am not sure.I already cleared it with zpool clear. This error is a last thing that worries me right now. What I want to understand is why both iostat and format show that all drives in the pool are Seagate which is not correct as two of them are WD. zpool status tank shows 7 drives: # zpool status tank pool: tank state: ONLINE scrub: none requested config: NAME STATE READ WRITE CKSUM tank ONLINE 0 0 0 raidz2 ONLINE 0 0 0 c1t1d0 ONLINE 0 0 0 c2t0d0 ONLINE 0 0 0 c2t2d0 ONLINE 0 0 0 c2t3d0 ONLINE 0 0 0 c2t4d0 ONLINE 0 0 0 c2t5d0 ONLINE 0 0 0 c2t7d0 ONLINE 0 0 0 What I can't understand is why 'iostat -En' says that all these drives above are Seagate ? 'iostat -En' does shows WD as well, but they show up at a bottom as sd11 and sd12?

If so, a pool export and re-import may be in order. 2.) are you sure the drive is failing? Does the problem only affect this drive or are other drives randomly affect too? If you've run 'zpool clear' and the problem comes back, something is wrong but it could also be RAM, CPU, motherboard, controller, or power supply problems. Smartmontools can read the drive SMART data and device error logs...run it from an Ubuntu 10.04 Live CD (sudo apt-get install smartmontools) or from a PartedMagic Live CD if you have trouble getting Smartmontools working on OpenSolaris with your hardware. 3.) on some systems I've found another version of the iostat command to be more useful, particularly when iostat -En leaves the serial number field empty or otherwise doesn't read the serial number correctly. Try this: iostat -Eni This should give you a list of drives showing their name in the cXtYdZsN format, and their Device ID which may contain the drive serial numbers concatenated with the model. Compare that list with your 'zpool status tank' output, which in your case means looking for 'c2t3d0'. Once you find the serial number, you can look at labels printed on your drives and verify which one it is. One tip: if your server case is hard to work in or it is otherwise difficult to remove drives to read the serial numbers (lots of screws, cables in the way, tight fits, etc.), create additional serial number labels for the drives and stick them on the drive in a place you can read them without removing the drive from the drive bay. This will make it easier to find a particular drive next time you need to replace or upgrade one. This problem most significant on hardware/OS combinations that don't provide a way to signal where a particular drive is physically installed. (This includes a lot of whitebox and small server hardware and OSes.) iostat relevant man page entries: http://docs.sun.com/app/docs/doc/816-5166/iostat-1m?l=en&n=1&a=view <http://docs.sun.com/app/docs/doc/816-5166/iostat-1m?l=en&n=1&a=view> -E Display all device error statistics. -i In -E output, display the Device ID instead of the Serial No. The Device Id is a unique identifier registered by a driver through ddi_devid_register(9F). -n Display names in descriptive format. For example, cXtYdZ, rmt/N, server:/export/path. By default, disks are identified by instance names such as ssd23 or md301. Combining the -n option with the -x option causes disk names to display in the cXtYdZsN format which is more easily associated with physical hardware characteristics. The cXtYdZsN format is particularly useful in FibreChannel (FC) environments where the FC World Wide Name appears in the t field.
