PRB: High Column of the Sysdevices Table Used for Dump Devices

 Last reviewed: April 25, 1997

The information in this article applies to: 

  - Microsoft SQL Server version 4.2 for OS/2

SYMPTOMS

Page 268 of the Microsoft SQL Server "System Administrator's Guide" and page 504 of the Microsoft SQL Server "Language Reference" state that the low and high columns in the sysdevices table are not used for dump devices. However, examining the sysdevices table reveals otherwise for floppy disk dump devices.

CAUSE

When creating floppy disk dump devices using sp_addumpdevice, the "media_capacity" parameter is divided by 62K and the result is placed in the high column in the sysdevices table. For example, if the default size for disk devices is used, the value 19 is placed in the high column of the sysdevices table (that is, 1.2 MB divided by 62K). Sp_helpdevice depends on this value to calculate the size of the floppy disk dump device for the description column of its output.
