Q

An Enterprise creates three 20 gb thin LUNs for the online transaction system, email and backup system In a 60 GB storage resource pool. As the company is in infancy, there is very little data on the online transaction system and email system. However, the amount of legacy data to be imported to backup system is about 40 GB which exceeds the capacity of the corresponding thin LUN As a result data fails to be write to the backup system.
