950-3976-01: Reference SPEC DRV SEA 36GB 15K FCAL T3Issue Description:
Seagate ST336752FC (36GB) disk drives should only be installed into
configurations which use Veritas Volume Manager or SDS RAID software,
or hardware RAID configurations, such as the T3.
Affected configurations include those where the Seagate ST336752FC
(36GB) disk drive is supported but is installed without proper RAID
control. These could include:
StorEdge T3/T3+ Array
StorEdge A5200 Array
StorEdge 6900 Array
StorEdge 3900 Array
To determine if the ST336752FC drive is installed in an array, do the
following. For the T3/T3+ , telnet to the T3 and run the 'fru list'
command. For the A5200, use 'luxadm inq '.
This drive is sensitive to rough handling and this may cause an
occasional need for logical block address (LBA) reassignment. In
RAID-based systems, this function is handled automatically without
operator intervention. In non-RAID configurations, this action
requires operator intervention and may include data loss from the
affected logical block addresses. There is no method for the customer
to verify if manual LBA reassignment has resulted in data loss on the
drive. Some operating environments cannot tolerate this behavior.
Therefore, this advisory is to ensure that this drive, when used as a
replacement FRU, or installed into a system, is NOT installed into a
non-RAID, non Veritas Volume Manager or SDS RAID environment.
This new sensitivity to handling is due to decreased head flying height
on the disk drive. Rough handling could introduce head slaps in the
landing zone of the disk platter and could lead to particle release
several hundred hours later in the drive's operating life. Particle
releases could lead to media degradation, reported as 03/1100 errors
(fatal read errors).
The exposure to data loss can be minimized by installing this drive in
a RAID or Veritas Volume Manager environment. Note that RAID 0 is not
an acceptable solution for this drive. Below is a description of the
various RAID configurations.
Raid 0 - Striping
Raid 1 - Mirroring
RAID 3 - Striping plus dedicated parity
Raid 4 - Modified striping with dedicated parity (never used or
implemented)
Raid 5 - Modified striping with interleaved parity
RAID 0+1 - Striping plus mirroring
Implementation:
---
| | MANDATORY (Fully Proactive)
---
---
| | CONTROLLED PROACTIVE (per Sun Geo Plan)
---
---
| X | REACTIVE (As Required)Corrective Action:
The following recommendation is provided as a guideline for authorized
Enterprise Services Field Representatives who may encounter the above
mentioned problem.
Ensure that Seagate ST336752FC (36.4GB) drives are installed in a RAID
environment using Veritas Volume Manager, SDS RAID, or hardware RAID
control. RAID 0 configurations are not acceptable in either hardware
RAID platforms, such as the T3, or software RAID environments.
Comments:
None
============================================================================
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.
