Re: [zfs-discuss] Help identify failed drive

Hi--

A google search of ST3500320AS turns up Seagate Barracuda drives.


All 7 drives in the pool tank are ST3500320AS. The other two c1t0d0
and c3d0 are unknown, but are not part of this pool.

You can also use fmdump -eV to see how long c2t3d0 has had problems.

Thanks,

Cindy

Thanks Cindy,

But format shows exactly same thing:
All of them appear as Seagate, no WD at all...
How could it be ???

Hi--

I don't know what's up with iostat -En but I think I remember a problem where 
iostat does not correctly report drives running in legacy IDE mode.

You might use the format utility to identify these devices.

Thanks,

Cindy

            c2t7d0  ONLINE       0     0     0

So I would like to replace 'c2t3d0'.

I know for a fact the pool has 7 physical drives : 5 of Seagate and 2 of WD.

I want to know if 'c2t3d0' Seagate or WD.

If I run 'iostat -En' it shows that all  c*t*d0 drives are Seagate and 
sd11/sd12 are WD.

This totally confuses me...
Why there are two different types of drives in iostat output : c*t*d0 and sd* 
???
How come all c*t*d0 appear as Seagate.I know for sure two of them are WD.
Why WD drives appears as sd* and not as c*t*d0 ?

Please help.
