Setting the TimeOutValue registry for Windows 2000 or 2003

This section describes how to ensure optimum availability and recoverability when you attach a storage unit to a Windows^® 2000 or 2003 host system by setting the Windows TimeOutValue registry.

You must set the TimeOutValue value associated with the supported host adapters to 60 seconds. The setting is consistent with the configuration for FC-AL adapters and disk subsystems when attached to Windows 2000 or 2003 host system.

The host adapter uses the TimeOutValue parameter to bind 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 adapter that is installed.

Follow these steps to modify the value in the Windows 2000 or 2003 registry.

From the Run menu or command prompt, type:
Regedt32.exe
Navigate to the following registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Disk
Look for the value called TimeOutValue. If the value called TimeOutValue does not exist, go to step 3.a. If the TimeOutValue exists, go to step 4.
1. Click Edit → Add Value...
2. For ValueName, type: TimeOutValue.
3. For data type, type: REG-DWORD.
4. Click OK.
5. For data, type: 3c.
6. For radix, click Hex.
7. Click OK.
If the value exists and is less than 0x0000003c (60 decimal), perform the following steps to increase it to 0x3c.
1. Click TimeOutValue.
2. Click Edit → DWORD....
3. For data, type: 3c.
4. For radix, click Hex.
5. Click OK.
Exit the Regedt32 program.
Restart your Windows 2000 or 2003 server for the changes to take effect.
