PROBLEM DESCRIPTION:
After extended run time in heavy disk access applications AND extended power
down times Quantum (model# VK4550J or VK45J05) 4.2GB, 3 1/2-inch, 7200 RPM
Single-Ended, Ultra/Wide SCSI disk drives may fail to spin up. These drives
are at risk of premature failure due to oil contamination which causes
a stiction failure in the HDA. Only disk drives in the following FRU serial
number range are affected:
0005181-97041Dxxxx to 0005181-97440Dxxxx
Since release of FCO A0113-2 new information has come to our attention:
The incidence of failure in the field installed base has been
significantly less than expected. As of 3/9/98 only eight sites
world wide had reported significant failue on a world wide installed
base of over 100K affected units.
We have learned that short duration power off events apparently do
not cause failures.
Sites reporting high failure have observed failures only after power
off times of a week or more.
Sites reporting high failure have been high duty cycle, heavy disk
access applications.
Potential for failure exists in a wider serial number range.
We no longer believe proactive replacement of affected product is appropriate
for all customer situations.
Recommended field actions:
1) Customer applications that do not fit the profile of heavy disk
access(*) followed by a long(**) power off cycle.
REPLACE ON FAILURE
In these situations the very low probability of failure does not
justify the disruption to the customer caused by upgrade.
2) Customer applications that do fit the profile of heavy disk
access(*) followed by a long(**) power off cycle.
PROACTIVE UPGRADE AVAILABLE
3) Any customer with an SSA with drives in the affected S/N range
SMCC IS OFFERING AN UPGRADE PROGRAM.
Customers can upgrade to an aggressively discounted A1000 or
A5000. Available products include:
UG-A5000-45GB-P 45GB Sun StorEdge A5000
UG-A5000-127GB-P 127GB Sun StorEdge A5000
UG-A5000-254-P 254GB Sun StorEdge A5000
UG-A1000-50GB-HW-P 50GB Sun StorEdge A1000
UG-A3000-63G-4D-P 63GB Sun StorEdge A3000
UG-RSM2000-9G-P 136GB Sun StorEdge A3000
Note: 45GB-P not offered on E10000.
Contact responsible local sales representative for details.
*Heavy disk access -All sites reporting failure have been described as
heavy disk access. Example our single internal Sun
site which experienced high failure was a benchmarking
center.
Unfortunately, due to the low number of sites reporting
failure we do not have data to quantify the disk duty
cycles vs point of failure.
**Long power off cycle -All sites reporting high failure experienced failure
after power off times of days. Some sites
reported numerous trouble free short duration power
cycle events (lasting hours) prior to observing
failure. In these cases point of failure was after
power off events of 7-10 days.
In November 1997 a redesign of the drives actuator bearing eliminated use
of the oil contaminant. Drives manufactured after this date do not have
the oil present so are not subject to this failure mode. The affected
disk drives may be identified in one of two ways;
1. ONLINE
Look for Quantum disk drives with model VK4550J and serial number
range 97041Dxxxx to 97440Dxxx. See COMMENTS for other options
2. VISUAL
Look for FRU p/n 540-2937 or 540-2938 and
FRU s/n between 0005181-97041Dxxxx to 0005181-97440Dxxxx
The S/N can be found on the FRU barcode label attached to the disk drive
bracket and on the disk drive manufacture label. An inspection of the
manufacturer's label on the drive shows model VK45J05.
IMPLEMENTATION:
---
| | MANDATORY (Fully Pro-Active)
---
---
| X | CONTROLLED PRO-ACTIVE (per Sun Geo Plan)
---
---
| X | UPON FAILURE
---
REPLACEMENT TIME ESTIMATE: 30 minutes (per drive)
SPECIAL CONSIDERATIONS:
IMPORTANT! Do NOT spin down affected disk drives for prolonged periods
until software is backed-up or off-loaded AND replacement disk
drives are available.
IMPORTANT! For SPARCstorage Arrays, ensure that the Controller contains 3.12
firmware PRIOR to powering down to install a replacement disk.
Failure to do so could possibly cause another failure when
attempting to power up, see FINI0339-1 for further details.
CORRECTIVE ACTION:
Where replacement is approved replace all Quantum 4.2GB (Vendor model number
VK45J05) disk drives having a serial number between 97041Dxxxx and 97440Dxxx
with Quantum 4.2GB drives with serial numbers outside the affected range or
Seagate 4.2GB drives as follows;
Replace 540-2937-01 with 540-2937-01
Replace 540-2938-02 with 540-2938-02

Implementation Footnote:
________________________
i) In case of Mandatory FCOs, SunService will attempt to contact all known
customers to recommend the part upgrade.
ii) For controlled proactive swap FCOs, SunService mission critical support
teams will initiate proactive swap efforts for their respective accounts,
as required.
iii) For Replace upon Failure FCOs, SunService partners will implement the
necessary corrective actions as and when they are required.
