KB:980054 Recommended hotfixes and updates for Windows Server 2008 R2-based server clusters

leave a comment »

From KB:980054
This article describes the hotfixes and updates that we recommend that you install on each node of a Windows Server 2008 R2-based failover cluster. When you update your Windows Server 2008 R2-based failover cluster, you help reduce downtime. You also help decrease the number of errors, failed print jobs, and other support issues that you experience.

We recommend that you install the following hotfixes if you plan to install the failover clustering feature on Windows Server 2008 R2 Core:
KB978309: IPv6 transition technologies, such as ISATAP, 6to4 and Teredo do not work on a computer that is running Windows Server 2008 R2 Server Core
KB976571: Stability update for Windows Server 2008 R2 Failover Print Clusters

KB2264080: Update rollup package for the Hyper-V role in Windows Server 2008 R2

leave a comment »

This article describes an update rollup package that resolves some issues for the Hyper-V role on a computer that is running Windows Server 2008 R2 and that is dated August 24, 2010.

Issue 1
When a computer has one or more Intel CPUs code-named Nehalem installed, you receive the following Stop error message:

0x00000101 ( parameter1 , 0000000000000000, parameter3 , 000000000000000c) CLOCK_WATCHDOG_TIMEOUT
Note The Nehalem CPU for a server is from the Intel Xeon processor 5500 series and for a client computer is from the Intel Core-i processor series.

Issue 2
Consider the following scenario:
You run a virtual machine (VM) on the computer.
You use a network adapter on the VM to access a network.
You establish many concurrent network connections. Or, there is heavy outgoing network traffic.
In this scenario, the network connection on the VM may be lost. Additionally, the network adapter is disabled.

Note You have to restart the VM to recover from this issue.

Issue 3
When a computer has an Intel Westmere processor, you receive an error message that resembles the following:
STOP: 0x0000001a ( Parameter1 , Parameter2 , Parameter3 , Parameter4 ) MEMORY_MANAGEMENT

From Virtual PC Guy’s Blog, here’s a documentation list for Dynamic Memory included in in the Windows Server 2008 R2 SP1 beta release:

Dynamic Memory Technical Overview whitepaper
This paper talks about what dynamic memory is, what it does and how it does it.  It is a good read for those curious to understand what is happening under the covers.

Hyper-V Dynamic Memory Evaluation Guide
This article steps you through the process of setting up SP1 and enabling dynamic memory.  It also gives you some good tips on configuration and troubleshooting.

Hyper-V Backups Cause Large Registry Files and may slow system boot

leave a comment »

Acording with Ben Armstrong and KB982210 – The startup time increases every time after you back up the data on all the disks of the computer in Windows Server 2008 R2 if the computer runs some virtual machines.

Note: the KB982210 applies to Windows Server 2008 R2 (not Windows Server 2008).

 

 

Additional Errors:

Log Name: System
Source: PlugPlayManager
Date: date time
Event ID: 12
Task Category: None
Level: Error
Keywords: Classic
User: N/A
Computer: computer name
Description:
The device ‘MSFT Virtual HD SCSI Disk Device’ (SCSI\Disk&Ven_MSFT&Prod_Virtual_HD\ GUID ) disappeared from the system without first being prepared for removal.

Short description by Ben Armstrong:
Whenever we backup a virtual machine using VSS, we momentarily connect the backup copy of the virtual machines virtual hard disks to the parent partition in order to clean them up after backup.  Unfortunately with Windows Server 2008 R2 a new plug-and-play entry would get created in the Windows registry each time that we did this.  Over time this would cause the registry to get larger and larger, which would in turn slow down the Windows boot process.
