Configuring for availability and recoverability for a Windows 2000 host
system
This section describes how to ensure optimum availability and recoverability when
you attach an ESS to a Windows 2000 host system. You must set the timeout value
associated with the supported host bus adapters to 240 seconds. The setting is
consistent with the configuration for IBM SSA adapters and disk subsystems when
attached to Windows 2000 host system.
The host bus adapter uses the timeout 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 2000 registry or in the device adapter parameters.
Setting the TimeOutValue registry
Perform the following steps to set the timeout 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.
