Hi all,

I have installed FreeBSD 9.1 on Dell PowerEdge r720. This server is
connected to the storage array Dell PowerVault MD3200 using SAS cables. I
have created a ZFS pool with the SAS disks (Dell PowerVault MD3200) and can
perform read/write operations in the pool without problems. However, when I
export the pool and then import it, the following errors are showed:

(da24:mps0:0:3:31): Field Replaceable Unit: 5
(da24:mps0:0:3:31): Error 22, Unretryable error
(da24:mps0:0:3:31): READ(10). CDB: 28 0 0 0 0 0 0 1 0 0
(da24:mps0:0:3:31): CAM status: SCSI Status Error
(da24:mps0:0:3:19): SCSI status: Check Condition
(da24:mps0:0:3:31): SCSI sense: ILLEGLA REQUEST asc:21,0 (Logical block
address out of range)


The device da24 is an access device to the storage array:

da24 at mps0 bus 0 scbus0 target 3 lun 31
da24: <DELL Universal Xport 0780> Fixed Direct Access SCSI-5 device
da24: 600.000MB/s transfers
da24: Command Queueing enabled
da24: 20MB (40960 512 byte sectors: 64H 32S/T 20C)

Why are those errors produced? Are they relevant? Can they be omitted?

Thanks. Regards.
