Initializing a Dell EqualLogic PS6000 Series Array

This morning we have just taken delivery of our third EqualLogic PS Series array. A PS6000 with 32TB of storage, this new addition to our SAN infrastructure is going to be a replication partner to our existing EqualLogic group. I am going to be blogging about this replication project as I get going with it but firstly thought I would take the opportunity go through deploying a PS Array step by step straight out of the box and creating a new group.

Hardware Installation.

Step 1:- Mount your EqualLogic in a rack, and if you like attach the front Bezel.

Step2:- Connect Power to the array, try and connect the 2 power supply modules to separate power sources for redundancy preferably on separate circuits, then use the ‘cable strain relief’ to secure the power plug to the array. As the Dell setup guide kindly points out the EqualLogic requires at least one power supply connected, this requirement is similar to pretty much all electrical devices, apart from those found at Hogwarts and powered by witch craft!

Step3:- Connect the Array to the network, If you have read my EqualLogic in a Hyper-V Environment Post I do talk a bit about network redundancy, and the network diagram below shows how your EqualLogic should be connected. Once again I am using Dell PowerConnect 5400 Series switches as a backend switch solution. - NOTE, if you have the dedicated management network enabled one of the below network connections will be to your corporate LAN, as this is a backend iSCSI network.

Step4:- Turn your EqualLogic Array on, on the back of the array on the Power Supply modules there is a rocker switch, turn both switches on and away you go.
Looking at the back of the Network Control module you can see which controller is active, indicated by the green light next to the ‘Act’ label on the module.
Now that you have the EqualLogic rack mounted, connected to a network and powered up you can begin the task of initializing the array. I have already written down all my IP address info prior to connecting and powering on the array. This Array will be on the same subnet as my existing EqualLogic group and will be the first member of a new group; this is because replication partners cannot be in the same group.

Software Installation.

Step1:- Install the Host Integration Toolkit HITKIT for short, the CD comes with the documentation.

Step2: Collect all the information you will need to complete the setup, IP address info etc.

Array Configuration;

Member Name:- Maximum of 63 letters, numbers or hyphens, the first character must be a letter.

Array IP address:- This must be on the same subnet as your group IP address

Subnet Mask:- Default is 255.255.255.0

Default Gateway:- Again must be in the same subnet as the Array IP and the Group IP address.

RAID Policy – This will depend on the amount of disks in the array. RAID 10,50,5,6

Group Configuration.

Group Name:- Maximum of 63 letters, numbers or hyphens, first character must be a letter.

Group IP address:- This is the address used to access the group, your iSCSI initiator will connect to this address.

Administration Password:- 3 to 16 letters or numbers, this is case sensitive and overrides the existing grpadmin password.

Membership Password:- 3 to 16 letters or numbers, case sensitive. This password will be used when adding additional members to the group.

CHAP user name:- Challenge Handshake Authentication Protocol or CHAP, is used by Microsoft services for authentication, you can configure your volumes to require CHAP authentication when Microsoft’s iSCSI initiator requests to connect to the volume. 3 to 63 letters or numbers.

CHAP Password:- 3 to 63 letters or numbers and again case sensitive.

Now that you have this information to hand you can begin to run Remote Setup Wizard installed with the HITKIT.

Below are Screen shots from the RSW installation. Each step required to complete the installation.

Once all these steps have been completed you can connect to your EqualLogic Group Manager using your webbrowser via the IP address you set earlier.

Now that the Array is initialized you can begin to configure the group and the dedicated management network. The dedicated management network usess the highest numbered interface on the controller in this case eth3 as this is the higest numbered port on both controllers this is the case with a PS6000 TYPE 7 controller a PS4000 TYPE 8 controller has the management port labelled as management and can only be used for the dedicated management network, the management configuration requires an IP address on your corporate LAN for the highest numbered port and also another IP for the management group. This creates a dedicated management network seperating iSCSI and management traffic allowing you to connect to your EqualLogic Array from the comfort of your desk using SANHQ or the group manager WebGui.

From the Gui you can configure the remainging eth's with IP address's on your backend iSCSI network create volumes and configure the volume access controls, configure VDS/VSS, E-Mail notifications and update the Array firmware and alot more!

I have initialized this array in about 1 and a half hours, bearing in mind I have been writing this post and eating Thai Chilli Beef (last nights left over tea), amongst a few other little jobs. With all the required information to hand there is no reason why you can not complete the whole task in half an hour.

    1. Thanks for this very useful post. I have just got a second hand one of these devices, mine has 16x1TB SATA, you say yours has 32TB, could you please tell me the drive model.

      I’m looking at potentially replacing my drives with third party ones and knowing the model of the approved 2TB drives would be very handy.

      TIA

    2. I setup the PS6000 but only 8 of the 16 discs were part of the group that setup. How do you get the other 8 discs to join the group or at least setup as a 2nd group?
