      Creating LUNs and mapping igroups ( 7 Mode & C - mode )

      Setting up LUNs and igroups using individual commands -  ( 7 Mode ) Instead of using LUN setup, you can use individual commands to create LUNs, create igroups, and map the LUNs to the appropriate igroups. Before you begin The LUN type must be specified. About this task After the LUN is created, you cannot modify the LUN host operating system type. Note: You can grow a LUN to approximately 10 times its original size. For example, if you create a 10 GB LUN, you can grow that LUN to approximately 100 GB. However, you cannot exceed 16 TB, which is the approximate maximum size of a LUN. Steps Create a space-reserved LUN by entering the following command on the storage system command line: lun create -s size -t ostype   lun_path -s   size indicates the size of the LUN to be created, in bytes by default. -t   ostype indicates the LUN type. The LUN type refers to the operating system type, which determines the geometry used to store da...
