•  The system is configured with Microsoft Windows NT 4.0 Enterprise, with any level Service Pack applied.
•  The Systems are running Microsoft Cluster Server version 1.0
•  One or more HSP/SHS devices are defined on adapter pairs

    ----- OR -----

   READY (RDY) devices are not part of any logical array configuration on a adapter pair in a cluster.

FIX:

1.  Apply the following updates:
   •  IBM ServeRAID BIOS and Firmware Diskette, Version 3.50,
      (Microsoft Certification Pending)
   •  IBM ServeRAID Device Drivers, Version 3.50,
      (Microsoft Certification Pending)
   •  IBM ServeRAID Administration and Monitoring Program Diskette, Version 3.50,
      (Microsoft Certification Pending)
   •  IBM ServeRAID Cluster Solution for Windows NT Diskette, Version 3.50,
      (Microsoft Certification Pending)
   •  IBM ServeRAID Command Line Program Diskette, Version 3.50,

2.  Create or recreate all HSP drive(s) using new Windows NT GUI ServeRAID Manager 3.50.
    This process will remove all stale data from the HSP drives.

    And remove all RDY drives from all shared channels.
