How to check raw storage allocated to my Linux server from SAN

Dear All
My Linux server version is
Red Hat Enterprise Linux Server release 5.7 (Tikanga)

SAN Storage team informed me that they have allocated 2000 GB of raw disk space to my server

But from df -h I can see only a total of about 500 GB space.
(/ , /home , /usr etc)
How can I see that allocated space & add it to my server?

df only shows the amount of mounted filesystems. You need to go one lvl deeper and see how much space the hard drive has. Use fdisk -l /dev/name_of_device to see infos about your hd.

Looks you are new to Linux with SAN.
You have to rescan fiber, then inspect devices. Probably configure multipath.
Then take care about LVM, create FS, mount it. Only then use "df".

Check this HOWTO:
