Hi all, Today i notice that one of the ZFS based servers within my company is complaining about disk errors, but i would like to know if this a real physical error or something like a transport error or something. The server in question runs snv_134 attached to 2 J4400 jbods , and the head-node has 2 hba's and i've enabled multipath support. I've 1TB sata enterprise class disks on the server.
The messages seen in the system are : Jul 15 12:30:48 storage01 fmd: [ID 377184 daemon.error] SUNW-MSG-ID: DISK-8000-4Q, TYPE: Fault, VER: 1, SEVERITY: Critical Jul 15 12:30:48 storage01 EVENT-TIME: Thu Jul 15 12:30:48 CEST 2010 Jul 15 12:30:48 storage01 PLATFORM: PowerEdge-R710, CSN: HR9SG9J, HOSTNAME: storage01 Jul 15 12:30:48 storage01 SOURCE: eft, REV: 1.16 Jul 15 12:30:48 storage01 EVENT-ID: 859b9d9c-1214-4302-8089-b9447619a2a1 Jul 15 12:30:48 storage01 DESC: The command was terminated with a non-recovered error condition that may have been caused by a flaw in the media or an error in the recorded data.

With this should i already start a disk replacement in the pool in question and then get a RMA with the disk vendor?
