Solution Type FAB (standard) Sure Solution 1000198.1 : Improved firmware for Seagate 10K.6 disk drives will reduce the incidence of unexpected outages due to a spindle motor issue.
PreviouslyPublishedAs 200251 Bug Id <SUNBUG: 5069315>, <SUNBUG: 4968898> Product Affected Products Listed Below Seagate Cheetah 7 FC-AL disk drives experiencing a higher than expected failure rate (see details below). Part
Impact Seagate Cheetah 7 FC-AL disk drive models ST336607FC, ST373307FC, ST3146807FC, and SCSI disk drive models ST336607LC, ST373307LC, ST3146807LC are experiencing a higher than expected failure rate due to premature spindle motor bearing failure. Engineering analysis of returned disk drives has revealed a higher than normal rate of a particular failure mode. While the overall global install base of Seagate Cheetah 10k.6 family of disk drives is meeting or close to meeting overall quality goals, Sun has been advised of certain instances of Cheetah 10k.6 disk drive issues impacting our customers. The following disk drive models are affected: Seagate Model# Description ST336607FC Cheetah 7 146LDD FCAL (36GB) ST373307FC Cheetah 7 146LD FCAL (73GB) ST3146807FC Cheetah 7 146LP FCAL (146GB) ST336607LC Cheetah 7 147LDD SCSI (36GB) ST373307LC Cheetah 7 147LD SCSI (73GB) ST3146807LC Cheetah 7 147LP SCSI (146GB) For all systems, to determine if a system has one of the Seagate Cheetah 7 drives, do one of the following:
For A1000/A3x00 Arrays attached to a host, an alternative would be to run one of the two following commands: A. #/usr/lib/osa/bin/drivutil -i <raid module specifier> Ex: #/usr/lib/osa/bin/drivutil -i c1t0d0 B. From RM6 GUI, RM6 GUI - Configuration - Module - Profile - drives For T3/T3+ arrays, an alternative would be to use Explorer output or T3 commands to identify the part numbers. The "fru list" command can be used. Another possible way to identify these disk drives for most, but not all, systems and arrays would be to use the "iostat" command. #iostat -En | grep -i vendor When this issue occurs, disk drives can fail with little or no warning. In systems protected by RAID configurations, data is protected. Those systems without RAID could suffer data loss. The specific failure mode is spindle motor failure. This failure mode results in a DNR or Drive Offline condition with no leading indicators or previous error messages. The most frequent messages seen are, "Drive not ready" or the drive may produce excessive read, write or media errors. Sample error messages: Mar 03 15:52:03 arr2 ISR1[1]: N: u1d07 SCSI Disk Error Occurred (path = 0x0) Mar 03 15:52:03 arr2 ISR1[1]: N: Sense Key = 0x1, Asc = 0x3, Ascq = 0x0 Mar 03 15:52:08 arr2 ISR1[1]: W: u1d07 SCSI Disk Error Occurred (path = 0x0) Mar 03 15:52:08 arr2 ISR1[1]: W: Sense Key = 0x3, Asc = 0x3, Ascq = 0x0 Mar 03 15:52:08 arr2 ISR1[1]: W: Sense Data Description = Peripheral Device Write Fault Mar 05 17:48:34 arr2 ISR1[1]: W: u1d07 SCSI Disk Error Occurred (path = 0x0) Mar 05 17:48:34 arr2 ISR1[1]: W: Sense Key = 0x3, Asc = 0x31, Ascq = 0x0 Mar 05 17:48:34 arr2 ISR1[1]: W: u1d07 SCSI Disk Error Occurred (path = 0x0) Mar 05 17:48:34 arr2 ISR1[1]: W: Sense Key = 0x4, Asc = 0x19, Ascq = 0x0 When this issue occurs, the following error codes may indicate that a drive has failed due to a failed spindle motor: "Sense Code 02x04".

Symptoms Root Cause Root cause analysis has determined that spindles at the end of the tolerance distribution may result in less oil, which may lead to inadequate lubrication and ultimately cause the drive to fail. The vendor has identified this as a 1% issue, though this may vary at individual sites. At the component level Seagate has implemented a new spindle motor design. This fix was implemented at Sun via ECO WO_27575 and DPCO 434. At the FW level this issue is addressed by new disk drive firmware patches. The new drive firmware monitors drive activity on Seagate Cheetah 10K.6 disk drives, and has an enhanced SMART feature to predict a premature failure of the spindle motor bearings. This will allow for graceful replacement before an outage occurs. An Upon Failure FCO has been released to facilitate hardware replacement for disk drives that experience this spindle motor issue. See FCO A0256-1.
