Appliance Model is NetBackup Appliance 5220.
Appliance Version is 2.5.3.
Appliance is configured as media server.
I read this technote http://www.symantec.com/business/support/index?page=content&id=HOWTO94258#v79361754. which is simple to follow.
question 1) but i m unable to find Manage > Storage > Disks. option disk is missing. Please suggest
esmadbck03.Manage> Storage
Entering Storage Administration view...
Add Add expansion unit storage.
Beacon Flashes or stops flashing the lights on all the disk drives of an expansion unit.
Exit Logout and exit from the current shell.
Monitor Monitor storage tasks.
Move Move storage partition from one device to another.
Remove Remove expansion unit storage.
Resize Resize storage partition.
Return Return to the previous menu.
Scan Refresh the storage disks and devices information.
Shell Shell operations.

question 2) 36TB of disk(dedupe) in use already How much time it wil take to redistribute data by appliance once I add 24TB of disk.
Question 1: The Manage > Storage > Disks is from the Web GUI not the CLISH. Use the "Add" option instead then the Resize Option to grow your pool.
Question 2: Good question but basically unanswerable because it depends on how busy the system is and if it need to re-level at all. New writes will go to the new disk but you may not redistribute any of the old data.
A1: manage > storage > add unit_3
A2: It is instantly available. The appliances uses vxvm and it just expands the concatenated volume housing your deduplication pool.
Note: It is not recommended to use the storage in the head (Unit_1) in the deduplication pool along with the disk shelves.
