Configuring iSCSI and management networks on a Dell EqualLogic PS-M4110 storage array

Quick instructions on setting up an EqualLogic PS-M4110 storage array.
In this case it’s a blade model located in a Dell M1000e chassis, slot 7 and 8.
Fabric B is the iSCSI fabric and fabric A is for management
We start by configuring fabric B, then A

Since there is no IP configured, we connect via serial.
Luckily the M1000e provides serial connectivity via the CMC as per the below:

SSH to CMC IP address:
==============================


Using username "root".

Welcome to the CMC firmware version 4.50.A00.201311120922

Switch to the EQL serial interface (connect to the slot ID)
==============================


$ connect server-7
Telnet escape character is '^\'.
Trying 169.254.31.7...
Connected to server-7.
Escape character is '^\'.

It appears that the storage array has not been configured.
Would you like to configure the array now ? (y/n) [n]y

Group Manager Setup Utility

The setup utility establishes the initial network and storage
configuration for a storage array and then configures the array
as a member of a new or existing group of arrays.

For help, enter a question mark (?) at a prompt.

Do you want to proceed (yes | no ) [no]: yes

Initializing. This may take several minutes to complete..

Enter the network configuration for the array.

Member name []: DSC-ARRAY-02
Network interface [eth0]:
IP address for network interface []: 192.168.105.29
Netmask [255.255.255.0]:
Default gateway [192.168.105.1]:

Initializing interface eth0. This may take a minute…..

Enter the IP address and name of the group that the array will join.

Note: If creating a new group, just enter the desired group name and IP
==============================


Group name []: DSC-SHARED-SAN
Group IP address []: 192.168.105.28

Searching to see if the group exists. This may take a few minutes.

The group does not exist or currently cannot be reached. Make sure
you have entered the correct group IP address and group name.

Do you want to create a new group (yes | no) [yes]:

Waiting for configuration to become active……Done

Group DSC-SHARED-SAN has been created with one member.
Use the Group Manager GUI or CLI to set the RAID policy
for the member. You can then create a volume which
a host can connect to using an iSCSI initiator.

To access the Group Manager GUI, specify http://group_ip_address in
a Web browser window. To access the CLI, use telnet or SSH to
connect to the group IP address from a remote terminal, or attach a
console terminal directly to a serial port on a group member’s
active control module. Log in to the default group administration
account (grpadmin) using the password you specified when creating
this group. See the Group Administration manual for more
information.
