Today we are going to discuss the NT Storage Device Stack in brief. I am sure most of you would have encountered a server hang issue where the one of the Antivirus or Storage driver was pointed out to be the root cause of the issue. It is important to understand the layers which are in picture when you are trying to write a file to the disk, because every I/O operation in windows is done via IRPs (I/O Request Packets - Data structures representing the I/O) and these IRPs have to pass through all the layers to achieve the completion of the task and any of these layer can potentially block the I/O from completion mostly due to code bug or at times due to the workload. NT-based operating system class and filter drivers for peripheral storage devices act as an interface between any intermediate or highest level drivers layered above the class or filter driver and a system-supplied port driver. I/O requests from a user application or kernel component reach storage class drivers through ...

With Storage Manager for SANs, you can create and manage logical unit numbers (LUNs) on Fibre Channel and iSCSI disk drive subsystems that support Virtual Disk Service (VDS) in your storage area network (SAN). This guide provides server and storage subsystem requirements, an introduction to managing LUNs, and step-by-step walkthroughs for creating and assigning LUNs using Storage Manager for SANs in Windows Server 2008.

Cluster validation wizard is used to check pre-requisite\best practices before building the cluster. While playing with my lab, I came across a issue under Network Test. Error: Found duplicate IP address fe80::100:7f:fffe%14 on node node1.vodka.com adapter Local Area Connection* X and node node2.vodka.com adapter Local Area Connection* X.   Resolution: It turns out that this is the result of the Teredo, an IPv6 Tunneling Protocol. Teredo allows IPv6 communications to pass through IPv4 NATs and IPv4 servers. However Teredo gives an identical IPv6 address to its network interfaces, which Failover Clustering flags as an error since it require unique IP addresses. So how do you fix this? There are 2 ways, some details are provided here: http://technet2.microsoft.com/WindowsVista/en/library/91d35c9f-3049-44f4-b711-743dc152c7c31033.mspx?mfr=true 1) Disable Teredo through command line a. Open ‘Command Prompt’ and ‘Run as Administrator’ b. Type: ...

Note the error message (Sometime the error message is very specific ) Login to the machine using local admin account Check the system Date and time / Time zone – Make sure they are similar to authenticating DC Check DNS – Make Sure they are pointing to Right DNS (DNS which is alive and doing the name resolution) Check DNS records with the help of NSLOOKUP Ping the DC – IP, Netbios Name and FQDn Ping the DC to DC with 1500 MTU Run Netdiag and check DNS and Trust and Kerberos test Make sure NIC card is enabled of “register me in DNS” Check event viewer for any know errors like Userenv, Kerberos, netlogon Enable netlogon log and do the further troubleshooting   Don't forget to post your comments :) Thanks, Anang Kumar
