Unfortunately, the mpt driver is closed source, so we can only infer what the code does by using the open source mpt_sas driver as (hopefully) a derivative. > > It is very appreciated if any one can help me out. > > Regards, > Ding > > [1] > Aug 16 13:14:16 nas-hz-02 scsi: WARNING: > /pci@0,0/pci8086,3410@9/pci8086,32c@0/pci1028,1f04@8 (mpt1): > Aug 16 13:14:16 nas-hz-02 Disconnected command timeout for Target 0 A command did not complete and the mpt driver reset the target. If that target is an expander, then everything behind the expander can reset, resulting in the aborts of any in-flight commands, as follows... > Aug 16 13:14:16 nas-hz-02 scsi: WARNING: > /scsi_vhci/disk@g60026b900053aa18000002a44b8f0ded (sd47): > Aug 16 13:14:16 nas-hz-02 Error for Command: write(10) > Error Level: Retryable > Aug 16 13:14:16 nas-hz-02 scsi: Requested Block: 1380679073 > Error Block: 1380679073 > Aug 16 13:14:16 nas-hz-02 scsi: Vendor: DELL > Serial Number: > Aug 16 13:14:16 nas-hz-02 scsi: Sense Key: Unit Attention > Aug 16 13:14:16 nas-hz-02 scsi: ASC: 0x29 (device internal reset), > ASCQ: 0x4, FRU: 0x0 > Aug 16 13:14:16 nas-hz-02 scsi: WARNING: > /scsi_vhci/disk@g60026b900053aa180000029e4b8f0d61 (sd41): > Aug 16 13:14:16 nas-hz-02 Error for Command: write(10) > Error Level: Retryable > Aug 16 13:14:16 nas-hz-02 scsi: Requested Block: 1380679072 > Error Block: 1380679072 > Aug 16 13:14:16 nas-hz-02 scsi: Vendor: DELL > Serial Number: > Aug 16 13:14:16 nas-hz-02 scsi: Sense Key: Unit Attention > Aug 16 13:14:16 nas-hz-02 scsi: ASC: 0x29 (device internal reset), > ASCQ: 0x4, FRU: 0x0 > Aug 16 13:14:16 nas-hz-02 scsi: WARNING: > /scsi_vhci/disk@g60026b900053aa18000002a24b8f0dc5 (sd45): > Aug 16 13:14:16 nas-hz-02 Error for Command: write(10) > Error Level: Retryable > Aug 16 13:14:16 nas-hz-02 scsi: Requested Block: 1380679073 > Error Block: 1380679073 > Aug 16 13:14:16 nas-hz-02 scsi: Vendor: DELL > Serial Number: > Aug 16 13:14:16 nas-hz-02 scsi: Sense Key: Unit Attention > Aug 16 13:14:16 nas-hz-02 scsi: ASC: 0x29 (device internal reset), > ASCQ: 0x4, FRU: 0x0 > Aug 16 13:14:16 nas-hz-02 scsi: WARNING: > /scsi_vhci/disk@g60026b900053aa180000029c4b8f0d35 (sd39): > Aug 16 13:14:16 nas-hz-02 Error for Command: write(10) > Error Level: Retryable > Aug 16 13:14:16 nas-hz-02 scsi: Requested Block: 1380679072 > Error Block: 1380679072 > Aug 16 13:14:16 nas-hz-02 scsi: Vendor: DELL > Serial Number: > Aug 16 13:14:16 nas-hz-02 scsi: Sense Key: Unit Attention > Aug 16 13:14:16 nas-hz-02 scsi: ASC: 0x29 (device internal reset), > ASCQ: 0x4, FRU: 0x0 > Aug 16 13:14:16 nas-hz-02 scsi: WARNING: > /scsi_vhci/disk@g60026b900053aa18000002984b8f0cd2 (sd35): > Aug 16 13:14:16 nas-hz-02 Error for Command: write(10) > Error Level: Retryable > Aug 16 13:14:16 nas-hz-02 scsi: Requested Block: 1380679072 > Error Block: 1380679072 > Aug 16 13:14:16 nas-hz-02 scsi: Vendor: DELL > Serial Number: > Aug 16 13:14:16 nas-hz-02 scsi: Sense Key: Unit Attention > Aug 16 13:14:16 nas-hz-02 scsi: ASC: 0x29 (device internal reset), > ASCQ: 0x4, FRU: 0x0 You will be happiest if you do not use SATA disks directly connected to SAS expanders. -- richard _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
