New Administration User Interface for Exchange Management Console

Hey All!

I’ve got more good news for MCTS (exchange 2007) and other exchange administrators, specifically in the form of the features of Microsoft Exchange 2007 with the new sp1.

A new administration user interface has been added to the Exchange Management Console for the POP3 and IMAP4 protocols. This administration user interface enables you to configure the following settings for POP3 and IMAP4 for your individual Client Access server: Port Settings, Authentication Settings, Connection Settings, and Message and Calendar settings.

Not only that, but Public folder management is also possible by using the Exchange Management Console. So now we can relax and handle it from the console rather than using Shell…

…Sweet.

Cisco Certification Spotlight: CCNA

Hi all,

Thought it’d be a good idea to give a quick breakdown of the different Cisco certifications over the next few weeks to cover what they entail. Let me know if there are any questions regarding these posts. I’m all ears!

The Cisco CCNA (Network Associate) certification validates the ability to install, configure, operate, and troubleshoot medium-size routed and switched networks, including implementation and verification of connections to remote sites in a WAN. This new curriculum includes basic mitigation of security threats, introduction to wireless networking concepts and terminology, and performance-based skills. This new curriculum also includes (but is not limited to) the use of these protocols: IP, Enhanced Interior Gateway Routing Protocol (EIGRP), Serial Line Interface Protocol Frame Relay, Routing Information Protocol Version 2 (RIPv2),VLANs, Ethernet, access control lists (ACLs)

Moving Root

You simulator is now usable, but you may have noticed aggr0, which contained the root volume (/vol/vol0) is raid type RAID 0. This is a characteristic of the simulator as it comes from Netapp. However, just like a real Network Appliance storage system, it is possible to move the root volume. I would like to do this in the interest of making the simulator configuration closer to the real hardware.

If you go to the front page of filerview there is a selection “Documentation specific to the filer”. You should see something like this:

Select Frequently asked Question and notice the first item on the list:

We’re basically going to go through the steps listed in answer to the question, “What is the procedure to convert vol0 from RAID 0 to RAID 4?”

Do a “sysconfig –r” from your storage system’s command line. You should see this:

Look at aggr0. Notice it contains 3 data disks, v4.16, v4.17, and v4.18. There are no parity drives and the raid type is raid0. You can see the attributes for vol0 by entering the command “vol status vol0”

You should see this:

So the first thing we need to do is create an aggregate where we are going to place our new root volume. Use the following command:

aggr create aggr1 3

This will create an aggregate with three disks. Once it is complete, enter the following command:

sysconfig –r

You should see the following:

Now we have an aggregate protected by parity. By default, when creating an aggregate the system will use RAID DP. Notice the two parity disks. (Of course, these are virtual disks which exist as files on the host OS).

Create the volume which will become our new new root volume by entering the following command:

vol create newvol aggr1 350m

If you type “df –m” you can compare the size of the existing root volume and the new volume. The new volume must be at least as large as the existing root volume.

Next, place the new volume in a restricted state with the following command:

vol restrict newvol

Before we can use the vol copy command, the target volume must be in a restricted state. This is because vol copy does a sequential copy of all the blocks from the source volume to the target. The target volume must be inaccessible while this process is continuing. Enter the following command:

Vol copy start vol0 newvol.

You should see the following output:

The copy process will not take very long. Once it is complete we can bring the volume back online with the following command:

vol online newvol

Then use the following command to make this the new root volume.

vol options newvol root

You should see something like the following output:

Notice the messages regarding the mailbox disk. Data ONTAP uses the mailbox disk as an alternate heartbeat path for the cluster software. If the heartbeat from the cluster interconnect should cease, each head will check the mailbox disk to see if the other head is still leaving messages. If it is, then the head may be operating properly and a problem may exist in the cluster interconnect.

In a future column we will remove the old aggr0 aggregate and the raid0 disks.

Unitek’s New Free Microsoft CRM Add-On!

Unitek’s Microsoft CRM Training Team periodically supplies FREE, useful tools for the CRM community! There is no charge to download and use these tools, either for yourself or your clients, but we do require that you complete a simple contact information form so that we can track the popularity and use of the specific tools.

We developed a method that gives users the ability to search Leads and Contacts simultaneously, with a single search. And as is our way, we want to share with the rest of the CRM community.

Ready To Go

Your Netapp simulator is now operational. It has a name and an IP address and you should now be able to access it through Filerview.

If you go to your web browser and enter the IP address of your filer you should see something like this:

At this point, we’re interested in the entry “Documentation specific to the simulator”. Select that option. You will see the following options:

The one we’re going to look at first is license keys. Take a look.

Here are simulator specific license keys for most of the Netapp product line. Notice there are keys for ISCSI but not FCP. FCP is one of the few products the filer does not support, but there are plenty of others. Clustering is supported, snapmirror, multistore, flexclone, snaprestore, snapvault … pretty much everything is here.

Go to your console and type license:

Notice that licenses are already installed for CIFS, NFS, ISCSI and snaprestore.

Next let’s go back to “documentation specific to the simulator” options and then select “frequently asked questions.”

There is a lot of good information here as well as on the installation instructions screen.

We’re going to take a look at the first one, converting vol0 from RAID 0 to RAID 4, next time. If you go to your console, or better yet, a telnet session into your simulator and type “sysconfig –r” you should see something like this:

Notice that first group of disks in aggr0. The RAID type is RAID0. Ordinarily (unless you are using a vfiler) you would not see aggregates with a raid type of RAID zero. They should be RAID 4 or RAID DP. To help keep the image size of the simulator smaller, (there is no parity information) Netapp has made the aggregate that supports /vol/vol0 RAID type 0.

In the interests of making the simulator behave closer to a real hardware storage controller our next project will be making a boot volume on an aggregate with normal RAID support. Also, we will be replacing the 126 MB drives with 526 MB drives.

Great News!

Hey Im an UNCLE!  Nothing to do with Cisco nor any sort of certification but I have a blog and I get to say what gets posted.  Call me Uncle Cisco!

Revised Book for Exchange 2007

Hey All!  Quick tidbit:  There is a revised book for exchange 2007 for the MCTS exchange 2007 Class.  It also talks about the new features with SP1.  And guess what?  It has the Virtual server images where Exchange 2007 is on Server 2008.

I just hope the exam (70-236) is the same as I feel the exam might change slightly because of the new questions on sp1.  We shall have to wait and see, but I will be certain to let you all know as soon as I do!
