Chapter 1. Implementing Fibre Channel host adapter cards 53
The host bus adapter uses the time-out parameter to bound its recovery actions
and responses to the disk subsystem. The value exists in different places in the
system configuration. You can retrieve and use it in different ways, depending on
the type of host bus adapter. The following instructions tell you how to modify the
value safely in either the Windows NT registry or in the device adapter
parameters.
1.10.8 Setting the TimeOutValue registry
The following instructions tell you how to set the time-out value registry:
1. From the Run menu or command prompt, type:
Regedt32.exe
2. Navigate to the following registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Disk
3. Look for the value called TimeOutValue. If the value called TimeOutValue
does not exist, go to step 3a. If the TimeOutValue exists, go to step 4.
a. Click Edit ->Add Value...
b. For ValueName, click TimeOutValue.
c. For data type, click REG_DWORD.
d. Click OK.
e. For data, click f0.
f. For radix, click Hex.
g. Click OK.
4. If the value exists and is less than 0x000000f0 (240 decimal), perform the
following steps to increase it to 0xf0:
a. Click TimeOutValue.
b. Click Edit ->DWORD...
c. For data, click f0.
d. For radix, click hex.
e. Click OK.
5. Exit the Regedt32 program.
6. Restart your Windows NT server for the changes to take effect.
1.10.9 Installing Emulex LP8000 adapter cards
This section tells you how to attach an ESS to a Windows NT host system with
Emulex LP8000 adapter cards. Single-and dual-port Fibre Channel interfaces
with the Emulex LP8000 adapter cards support the following public and private
loop modes:
