Error:
Invalid Operation
Disk resource Pending Timeout for large configurations
To ensure continuous operation of disk resources across a SAN with disk resource counts greater than 8,
HP recommends that you increase the Pending Timeout value for each disk resource from 180 seconds
to 360 seconds.
To view and set the Pending Timeout value:
1. Open the Microsoft Cluster Administrator.
2. Select a disk resource in the left pane.
3. One at a time, right-click each disk resource in the right pane and select Properties.
4. Click the Advanced tab on the Properties menu.
5. Change the Pending Timeout value to 360.
6. Click OK.
Host server considerations
This section provides important information about the host server.
Windows 2000 and Windows Server 2003 considerations
Drive-let er remapping can occur in the following situations and can affect data access.
• Replacing one server with another
• Replacing an FCA in one of your systems
During a server or adapter changeover, use Disk Manager to manually remap drives to drive
let ers. This restores proper access to your data.
When you replace an FCA in a server, you must reinstall the adapter driver. Windows 2000
and Windows Server 2003 automatically reload the original adapter driver and reset important
registry set ings. New connections are created on the HSV controller. Assign the new WWNs to
the appropriate host.
Registry growth in Windows
The Windows plug-and-play feature limits the number of plug-and-play devices that are added or removed
from the registry. When you add or remove devices, or create or delete snapshots, the plug-and-play
manager adds entries to the registry, which can cause the registry to exceed the allowed capacity.
If the registry contains more than 700 entries, the next time the system reboots, the following error
message appears: Failed to load Windows 2000 due to a file missing or corrupt
in the \WINNT\SYSTEM32\CONFIG\SYSTEM directory.
See the Microsoft Knowledge Base article (Q269075) for more information about the registry growth issue.
Known limitations for large LUNs in Windows 2000
In Windows 2000, if you remove any logical unit number (LUN) greater than 7, and then you perform a
subsequent disk scan, the Found New Hardware wizard may ask you to finish installing the device that
was removed. The Device Manager may display the device with a yellow warning icon. Reboot the
system to remove the device.
Windows 2000 dynamic disk snapshots and snapclones
The Windows 2000 environment does not support the use of snapshots and snapclones in HP SANs if the
snapshot or snapclone is presented to the same host as the LUN from which the snapshot or snapclone
