Allocating SAN Volume to Virtual Host Using IBM DS83K Storage SubSystem
While searching on the web to allocating San volume step by
step guide I have found many resources but none of them describe all the
necessary steps. The guide has been written to keep these findings in mind so
that one can look into the guide and able to work at own. The guide has been
divided into different sections for purpose of clear understanding.

Switch Section

SAN Section

Host Section
Switch Section
First you have to lay fiber cable between the Host (physical
\ virtual) and SAN switch. Look into the switch to see the open ports and
connect the cable between the two end points.
Login to switch and look at the status of port, f-port means
the connection is successful.
Please note the WWN number as mentioned below at the end of
the string. This can be verified from the host, if you are using a virtual host.
In case of physical host this can also be checked using command. In our case we
are allocating san storage to virtual host.
Click the
configuration tab as mentioned below.
Our next step is to create an alias, zone on the switch so
that we can control the access of this LUN from different hosts. To do this we
have to login to switch to configure alias first.
Create a new alias, and press OK button 
The new name will be shown in the drop down menu. Select the
port to which cable has connected, make it the member of this alias as shown.
In our case port is 12. Click add member
Select the zone tab, create a new zone and type a
distinguish name for the zone. You can use the name of the alias and put Z at
the end of the string to distinguish it as zone name.
Now the zone contains the alias i.e port and controller as
shown
Click the zone config tab and add the newly configure zone to
its member and click add members.
Now first save the configuration and then enable it.
That’s it all you have to do at switch level, next our
target is to configure SAN Storage.
SAN Section
Log in to san box and
open the element manager as mentioned below
The element manager opens up with the following output. This
is the main page of our SAN interface, you will see different configuration
options.
Click Open System Volume Group
Select the open system volume group to create the volume
group and add the volume to it.
Click
create button as mentioned and select the extent pool which has maximum size or
select the pool you want to allocate volume from that. The extent pool might be
Raid 5, Raid 10 or any other configuration matches your requirement.
Enter the name of the volume group and note the volume id
when created. The host type will be selected as per the requirements, in my
case I am using virtual host so I have selected VMWare ESX connection host
type, one can select windows, linux host connection types alternatively.
Click next button and the volume group will be created with
this specification mentioned above.
Click finish to have this done.
Now add volume to this volume group as mentioned below. Select
new volume option mentioned below to select the volume group and add the volume
to it.
Select new volume and enter the appropriate values. The
volume type will not be changed in my case, enter size of the volume and
quantity i.e 1 or 2 volume and enter the nickname this is optional
Once finished, the volume has successfully added to the
volume group configured earlier.
The last section is to configure the host connection; in
this section we will map this volume with the host so that host can see the
volume. Select host connection
