        -  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 SRDB 
          17643 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).
 
        - 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).

          21101).
 
        - After disk replacement in A5000 (Photon), Volume Manager gets error: 
          cxtxxdxsx online failed : device path not valid (SRDB 17003).

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).

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).
