Brocade Zone Setup

I recently setup a Brocade SAN Switch for zones in an HP C7000 Blade Enclosure. I thought I would run through all of the steps.

Step 1.
To configure the switch, log into the HP On-Board Administrator and locate the blade switch you plan on zoning. Click on the Management Console to launch the Management Console.

Step 2.
After you enter the username and password the web tools administration page will be displayed as below. Click on the Zone Admin to launch the zone configuration page.

Step 3.
The Zone Administration page starts out with the Alias tab highlighted. Aliases are nothing more then a common name to the WWN for the devices. Use the alias in order to more easily identify the connections. In order to create an alias click on the New Alias button and then create a name which you believe will help you configure the switch more easily. For example you might call one of the Aliases something like Blade_01, Backup_A, App_02. Remember that if you have multipathing or redundant connections you should name each Aliases so you know can identified them. Take some time to figure out your schema.

Once you have created the Alias you need to map it to the WWN in the left column. Use the "+" to drill down until you find the device and then click "Add Member".

NOTE: The ideal way to build the configuration may be to power up each device one at a time and then assign the Alias name.

Step 4.
After you have created the aliases you can create your Zones. Click on the Zone tab and then click the New Zone. As with Aliases you need to find a suitable name for Zone. Once you have entered the name of the Zone then you need to assign the connections to the zone. Your Aliases will be listed at the bottom. You will need to add all of the connections that will see each other in the zone. An example would be the Storage Array to the Server. Only member in the zone can see each other everything else will be shielded.

Step 5.
Now that you have the Zones configured you need to create the config. This is kind of like the recipe for the switch. The zones are the ingredients and the config is the completed setup, which the switch operates. To build the Zone config, click on New Zone Config and create a name. As with all of the naming convention choose a name that best describes the configuration you want to push to the switch. An example might be Phase01 or Production. Once you are sure you want to enable the Configuration then click on Save Config, then Enable Config. Make sure and watch the output in the window at the bottom. The Save must complete fully before enabling.

VMware View 4 Security Server Tips

I finally got the VMware View Security server working correctly so that I could use it for our company. Here are some tips for you when working with it.

On the Main Connection Server make a config file using the top right corner of the something. Export the config file to the desktop.

Open the Security Server and navigate to the location of the folder to put the file.

Restart the service and then try to connect from outside the network. Remember that only RDP will work through the security server.

CactiEZ Problems

Just recently I downloaded the ISO from torrent and setup a new Cacti server. This is one of my favorite monitoring systems which is free. If you recently set one up you notice a bit of frustration in that it did not work right out the gate. Here is what I had to change in order to get the poller running and a few tip and tricks.

First the poller. Log into the console or from ssh as "root". Once you have logged into the server then do the following TWO command.
cd /var/www/html/poller.php
vi poller.php
If you're not use to the VI console then read on otherwise skip to this section..

VI QuickTips

Navigating the code: Use the arrows to skim through the code.
Typing: Once you found your place to start typing just start typing, escape to navigate using arrows.
Exiting and Saving: press escape key if you have been typing, then :wq

Ok about a page or two into the code you will find the line that look like this..
$force = FALSE
Change it to TRUE and then save the code. You will need to run the poller manually in the web interface and then come back and follow the steps after running it manually back to FALSE. This should kick the poller to start to collect stats for you.


Couple of other things you might want to get running on the machine. Run these command as root from the terminal window.

Changing the network options
Synching the Time
ntpdate -u
Nightly updates - if you run into a lot of log problems with the server shut off updates.
service yum stop
chkconfig yum off
Changing the timezone
yum install system-config-date
That should about do it. I love working with this software and it will certainly help you figure out where most of your problems reside.
