If condition on shell not working , not sure what is the mistake I am doing?
I have a requirement to perform specific set of tasks based on server , So I want to have the condition(s) defined based on server. Here is the script I came up with and I have read multiple blogs and couldn`t find any mistake from my script. Can you guide on what I am overlooking here ?

Code:
#!/bin/bash
SERVER_NAME=`hostname -s`
hostname -s
DBServer=(servr1 servr2 servr3 servr4)
echo "Values of DBServer seeing is ${DBServer[*]}"
Values of DBServer seeing is servr1 servr2 servr3 servr4
for i in ${DBServer[*]}
do
  echo "current value in I is $i"
  echo "The server name found is $SERVER_NAME"
  if [$SERVER_NAME == $i]
  then
    echo "I am on one of the servers and it is $i"
  fi
done

Output I see on server is

Code:
current value in I is servr1
The server name found is servr1
-bash: [servr1: command not found
current value in I is servr2
The server name found is servr1
-bash: [servr1: command not found
current value in I is servr3
The server name found is servr1
-bash: [servr1: command not found
current value in I is servr4
The server name found is servr1
-bash: [servr1: command not found

gst-complete-0.8

gst-complete-0.8(1)						   User Commands					       gst-complete-0.8(1)

NAME

       gst-complete-0.8, gst-complete - perform bash completion for gst-launch command lines

SYNOPSIS

       complete -Cgst-complete-0.8 gst-launch

       gst-complete [--gst-list-mm] [--gst-mm=string] [--print]

DESCRIPTION

       gst-complete-0.8 enables bash to provide context-sensitive tab completion for gst-launch command lines. See gst-launch(1) for the syntax of
       gst-launch command lines.

       You must have a version of bash that supports programmable completion. Such versions of bash provide the complete built-in command.

       gst-complete is a wrapper script that runs the latest installed version of gst-complete-X.X. For example, if both gst-complete-0.7 and gst-
       complete-0.8 are installed on your system, gst-complete runs gst-complete-0.8.

OPTIONS

       The following options are supported by gst-complete-0.8 and gst-complete:

       --help	       Display detailed usage message. You can also use -? to specify this option.

       The following options are supported by gst-complete only:

       --gst-list-mm   List found major/minor versions. This option displays the versions that are available.

       --gst-mm=string Force  major/minor  version.  This  option  enables you to specify a specific version to run, if you do not want to run the
		       default version.

       --print	       Print wrapped command line. This option displays the command that will be run, and then runs the command.

EXAMPLES

       Example 1: Generating the Registry of Available Plugins by Running gst-compprep

       Run the following command in your .bash_profile or other appropriate place:

       example% complete -C gst-complete-0.8 gst-launch

       Example 2: Running the Wrapper Script and Displaying the Command Name

       example% gst-complete --print
       /usr/bin/gst-complete-0.8

FILES

       The following files are used by this application:

       /usr/bin/gst-complete-0.Executable for bash completion for gst-launch

       /usr/bin/gst-complete   Wrapper script that runs the latest installed version of gst-complete-X.X
