Using Windows Nt Scsi Parameters - HP D5970A - NetServer - LCII Installation And Configuration Manual

Using Windows NT SCSI Parameters

Follow the instructions below to enter the registry values that affect how the
Windows NT SCSI manager interprets the generic configuration information of
SCSI device drivers. All SCSI host adapters installed in your system are
affected by the values you enter here. A list of valid values follows:
NOTE
The following value keys are case-sensitive and must be entered
exactly as shown.
• DisableTaggedQueuing — A nonzero value indicates that the SCSI host
adapter disables tagged queueing for SCSI devices. The data type for this
value is REG_SZ.
• DisableSynchronousTransfers — A nonzero value indicates that the
SCSI host adapter is not to initiate synchronous negotiations (but it may
still accept negotiations initiated by a SCSI target). The data type for this
value is REG_SZ.
• DisableDisconnects — A nonzero value indicates that targets are not
permitted to disconnect during the execution of a SCSI command. The
data type for this value is REG_DWORD.
• MaximumLogicalUnit — This can limit the scan for connected devices
on the SCSI bus. Valid values are 1 to 8. If 1 is specified, the Windows
NT SCSI manager assumes that no SCSI targets support LUNs other
than 0. Otherwise, LUNs from 0 to 8 are scanned during system
initialization. The data type for this value is REG_DWORD.
• Maximum SGList — Specifies the maximum number of Scatter/Gather
elements. Valid values are 17-255. The data type for this value is
REG_DWORD.
To enter Windows NT parameters, follow these steps:
1. Select Run from the Start button.
2. Type regedt32 and press Enter.
3. Open the registry list to the following location:
\HKEY_LOCAL_MACHINE\System\CurrentControlSet\
Services\adpu160m\Parameters\Device
