Greetings,
    One or more of the hard drives in the A1000 seem to have bad
sectors. I get the following error messages:

Sep 29 01:24:11 biotools rdriver: [ID 486355 kern.notice]
ID[RAIDarray.rdriver.4003] The Array driver is returning an Errored I/O,
with errno 5, on a1000_1,
Lun 2, sector 1712
 
I googled for any tips, and found the website regarding SCSI sense Key
Description, but nothing more specific.
 
I know, from the logs, where the bad sector is, on a1000_1, Lun2.
However, there are four disks in this Lun ,so how do I isolate the
problem?
 
I have also noticed that these errors are spit out only when someone
sshs to the server. What could be wrong? (Something related to
/export/home I presume?)
 
Thanks for your time and any help is greatly appreciated.
