Various applications running on Sun StorEdge A5000 units with 9GB ST19171FC drives may report SCSI transport, SCSI reset or read errors (FIN I0503-1).
Recovering from a root filesystem disk failure or corruption on an internal FC-AL boot disk in an E3500 Server or a FC-AL boot disk in a A5000 which is not mirrored with SEVM or SDS (FIN I0421-1). Note: This FIN was written before there was an official fix for this; also refer to Problem artcile 1008580.1 if this problem is experienced.
Empty backplane/incorrect configuration on Sun StorEdge A5x00 can Cause Errors. Empty backplanes can generate errors which are intermittent and difficult to isolate (FIN I0400-2).
Seagate Cheetah 7 FC-AL and SCSI disk drives with serial numbers below 60000 are experiencing a higher than expected failure rate due to a spindle motor issue (FCO A0239-1).
Seagate 4 FCAL and SCSI Disk Drives may experience higher than expected failure rates (FCO A0222-1).
Rare but recoverable "write faults" may occur when adding or upgrading 18.2GB 7200 RPM FC-AL drives into the Sun StorEdge A5000 that were manufactured before January 1, 1999 (FCO A0147-1).

GBIC

Some Vixel Short Wave GBICs 370-2303 has been identified as Long Wave when installed in A5x00 storage array (FIN I1120-1).
Visual identification of -02 and -03 GBICs without physically removing from system (FIN I0502-1).
A small percentage of Vixel GBICs (370-2303-02) are demonstrating symptoms consistent with marginal signal quality on the GBaud FC-AL loops. Marginal signal quality can be caused by variations in component quality for GBICs, backplanes, interface boards, interconnect assemblies, and FC drives (FCO A0144-3).

The revision level printed on the labels for the 7-slot Backplane and the 11-slot Backplane for the A5000, A5100, and A5200 array are different than the revision levels that are dynamically reported by the arrays (FIN I0501-1).

Interconnect Assembly

7-19

SMCC Engineering has noted several isolated instances involving the Enterprise Network Array[tm], where the EMI clip sandwiched between the underside of the Horizontal Interconnect Board and the top edge of the Vertical Interconnect Board nearest the Interface Boards, had shifted just far enough to allow the EMI clip to overlap and make contact with the soldermask over the Fibre Channel signal traces (FIN I0373-1).
