Failed to find directory “\\ExchangeServerName\c$\Perflogs’ on the server

Filed under: General — telnet25 @ 5:00 pm

Problem:

Running META ( exchange troubleshooting Assistance on Cluster servers) producing error

“Failed to find directory “\\ExchangeServerName\c$\Perflogs’ on the server”

Fix:

  • Click on Hide advance data collections options
  • Go to Data Directory on the server

in here place the IP address of the CMS server as shown below

wincms

192.168.1.100

CMS IP

scc1

192.168.1.101

Node 1 ( Physical)

scc2

192.168.1.102

Node  2 ( Physical)

The problem is if you do , on one of the nodes if you click on run and do double back slash

\\CMSName\e$\Perflogs    ( in this example per flogs folders in being created on E drive) you get errors as shown below

If you do same with IP address instead of name , you will see the directory is accessible.

\\192.168.1.100\e$\PerfLogs

This is why the META isn’t working , you will need to make sure the IP is there as shown below

To be honest I was not able to determine the root cause, the DNS and WINS appears to be working correctly in this situation.

Anyways the goal is to make META happy (-: and move on  this will be one way of doing it

Cluster Quorum & recover Quorum

Filed under: General — telnet25 @ 11:17 pm

I happen to be part of troubleshooting SQL cluster today. which was two node active passive cluster. The issue was the disk resources where not available for what ever reason SAN environment had. After bringing disk resources online we realized the Quorum disk was gone, and little more investigation we saw it was gone for good, even from SAN.

We end up having working cluster with no “Quorum” windows 20008 SQL cluster. I knew creating quorum resource wasn’t a bid deal and wanted list the steps here incase any of you falls into same shoes.

Fist make sure your SAN guy maps  shared disk to your existing cluster. Give it a drive letter to your shared disk in most cases 1 GIG is plenty enough.

Quorum resource

In every cluster, a single resource is designated as the quorum resource. This resource maintains the configuration data necessary for recovery of the cluster. This data, in the form of recovery logs, contains details of all of the changes that have been applied to the cluster database. This provides node-independent storage for cluster configuration and state data.

TechNet

Now  you have the “Q” drive is waiting to be the quorum fallow the steps below.

To configure the quorum in a failover cluster:

  • Open the Failover Cluster Management console
    Select the name of the cluster you have just created.
  • Right-click on the cluster,
    select More Actions, and click Configure Cluster Quorum Settings, This will open up the Configure Cluster Quorum Wizard, and fallow the steps listed below to create the required files for healthy quorum.

After making sure all looks good you can go back to Q disk and will notice there are cluster configuration files in there.

Migration Exchange Servers to Exchange 2010

Filed under: General — telnet25 @ 2:45 am

I am sure one of the most asked question will be , how do I migrate from Exchange X version ( mostly 2003 I suspect (-: to Exchange 2010?

In general migration is much easier in my opinion. IF you have ever done migration in the past you will know the main focus points always been in a nut shell

  • Size the new exchange 2010 server ( hardware configuration, mailbox , Hub, CAS, Edge etc )
  • calculate the IOPS
  • Design SG / DB for Exchange server or Servers
  • Design or Architect the roles  ( Number of servers )
  • Decide high availability ( cluster etc)
  • Implement  / Execute the plan
  • Once you have your  new Exchange ( new one 210 in this  example) server use mailbox move wizard to move mailboxes over to it.
  • Use MS articles to make sure migration is smooth, move all required Exchange data, PF folders, mailboxes etc
  • Make use mail flow works , other services are running properly OWA, Outlook anywhere etc…
  • Shut down the old exchange server to make sure nothing is getting crazy
  • After make sure everyone is happy Un-install your legacy Exchange server and complete the migration.

As you can see from basic steps the required actions takes planning and doing your homework correctly (-:

Since Exchange 2010 is not upgrade to Exchange 2007, and it is entirely different powerful application you may want to take a bit more time to investigate some of outstanding futures, the redundancy option is one of the most powerful future ( DAG), High Availability and Site Resilience.
