PROBLEM DESCRIPTION :

Seagate 20.0GB and 20.4GB disk drives, used on Ultra 10 and Sun Blade 100
systems, are both identified with the same SUN part number (370-4327).
A problem can arise when a replacement of one of the mirrored disk drives
is required.

If a mirrored 20GB disk drive fails on one of these platforms it is
important to ensure that the same capacity drive is used so that
the replacement drive is compatable with it's mirrored counter-part.
In some cases it may be necessary to replace both 20GB disk drives
to ensure they both are of the same capacity.

The root cause of this problem is that there are two drives with two
similar but different capacities reporting to the same part number
(F370-4327). The failing condition exist when disk mirroring is used
and the drive capacities are not similar.

The corrective action was made available via ECO WO_24317 on
August 7, 2002 releasing part number 370-5560-01, which is a 20.4GB
(only) disk drive.

When replacing a failed 20GB mirrored disk drive on a Ultra 10 or
Sun Blade 100 system please follow the instructions listed in the
Corrective Action section below.

PLANNED IMPLEMENTATION COMPLETION DATE: September 30, 2004

SPECIAL CONSIDERATION :

CORRECTIVE ACTION :

For those customers who have experienced a failure on a mirrored
Seagate 20.0GB or 20.4GB disk drive, follow the below guidelines;

1. If the system has mirrored 20.4GB disk drives, replace the faulty
   drive with part number 370-5560.

2. If the system has mirrored 20.0GB disk drives, replace both drives
   with part number 370-5560, thus ensuring matching capacities.

If the service is being done for a customer NOT covered under a
product warranty or service contract, the second drive should be
provided at no cost to the customer.

COMMENTS :

For those customers who do NOT mirror their disk drives and
experience a 20GB disk failure, please continue to use Sun
part number 370-4327 as the replacement.
