PROBLEM DESCRIPTION:
Power sequencer cables in StorEdge A3500/A3500FC 1x5 configurations
may be connected incorrectly, causing potential data access issues.
The L5, R5, L6, and R6 power sequencer cables on a certain number of
A3500/A3500FC arrays were installed in the wrong order at Sun
Manufacturing. This causes the controllers to power-up before the
D1000 disk trays. The controllers search for disks and try to configure
LUN's while the disks are still spinning up.
This cabling issue may also cause one controller in the A3500 to create
fewer than the expected number of LUN's and to grab all of the disk
drives. The other controller will have no LUN's. This could be a
performance issue because only one controller would be handling the
disk drives.
The affected units will most likely exhibit these types of problems
when being installed for the first time, or when they are powered up
after being shut down for maintenance.
There were approximately 480 miswired A3500 1x5 configurations shipped
from US Manufacturing and 159 shipped from the UK. All 1x5 A3500/A3500FC
configurations shipped between February 2, 2000 and September 28, 2000
are impacted. A complete list of serial numbers for the affected systems
can be viewed per instructions given with Corrective Action below.
Manufacturing Assembly Instruction (MAI) 915-1873-03 did not accurately
describe cable positioning for power cables 5 and 6 as was correctly
stated in document 805-4981-13 of the A3500/A3500FC Hardware
Configuration Guide.
A3500/A3500FC racks which are incorrectly cabled must be manually
reconfigured according to the Corrective Action section below.
IMPLEMENTATION:
---
| | MANDATORY (Fully Pro-Active)

| X | CONTROLLED PRO-ACTIVE (per Sun Geo Plan)

| | REACTIVE (As Required)

CORRECTIVE ACTION:
An Authorized Enterprise Field Service Representative may avoid the
above mentioned problems by following the recommendations as shown
below.
A list of A3500/A3500FC racks which were shipped with improperly
connected power sequencer cables can be viewed at the URL:

Click on Proactive Swap Programs
Then look under the link of FIN I0637-1 and select either
Affected Product Serial Number List-UK Manufacturing Shipments(postscript)
or
Affected Product Serial Number List-US Manufacturing Shipments(postscript)
to observe the serial numbers and customer names that manufacturing has
determined to be affected.
Since the affected A3500 were shipped between February to September of
2000, the serial number on the rack will range between 005xxxxx to 038xxxxx.
If an A3500 1x5 configuration is suspected of being miscabled, visually
inspect the power sequencer cable connections and compare them to the
diagram on page 3-16, section 3.3.2 of the A3500/A3500FC Hardware
Configuration Guide. In summary, L6/R6 should be fitted to a D1000
tray and L5/R5 should be fitted to the controller module.
If the connections are incorrect, perform the following rework.
Read through this entire procedure prior to starting rework.
NOTE1: This procedure provides the steps necessary to swap the
AC power cords between the top D1000 tray and the A3500 controller
module. Since you will be shutting down one power supply on the
controller module at a time, the system is exposed to a single
point of failure during this process which takes around seconds.
You should be familiar with the whole process before starting the
re-cabling.
NOTE2: All cables have labels indicating that they are L5, L6, R5, R6, etc.
1) Verify that power supplies in the controller module and top D1000 tray
are working by performing a Healthcheck on the controller module and on
the D1000 tray. Healthcheck can be run from the Raid Manager Recovery Guru
or by using the command line 'healthchk' command.
2) Check the LED's on the Power Supply to verify once more that the power
supply is working properly. If the power supplies are working, continue
with the remaining steps of this process. If any of the power supplies
are not working, fix them before proceeding further.
3) Viewing the rack system from the rear, rework the right side power sequencer
cables. On the controller module, turn off power supply by flipping off
the power switch located on the right hand side controller power supply,
then unplug the AC cord.
CAUTION: Do not turn off the power switch located on the D1000 because the
switch on the D1000 powers off both the left and right hand side power
supplies for the D1000 tray.
4) Unplug the AC cord from the right hand side of the D1000 power supply then
plug this AC cord into the right hand side controller module power
supply. Turn on the right hand side controller module power supply by
flipping the power switch on the power supply.
5) Plug the other AC cord that you removed from the controller power supply
in step 3 into the D1000 power supply.
6) Check the LED's on the power supply for both the controller module and
the D1000 tray to verify functionality.
7) Run another Healthcheck on both the controller module and D1000 tray.
If any power supply fails, repair the power supply before proceeding to
the next step.
8) Repeat steps 3 through 7 for the left-side power sequencer cord
connections.
NOTE3: Please reference section 3.3.2, page 3-16, of document 805-4981-13
(A3500/A3500FC Hardware Configuration Guide). Note that L6/R6
should now be fitted to the D1000 tray and L5/R5 should be fitted
to the controller module once the rework is complete.
COMMENTS:
------------------------------------------------------------------------------
Implementation Footnote:
i) In case of MANDATORY FINs, Enterprise Services will attempt to
contact all affected customers to recommend implementation of
the FIN.
ii) For CONTROLLED PROACTIVE FINs, Enterprise Services mission critical
support teams will recommend implementation of the FIN (to their
respective accounts), at the convenience of the customer.
iii) For REACTIVE FINs, Enterprise Services will implement the FIN as the
need arises.
