If not specified, the lowest available number(the default value) is assigned to the LUN.-rg rgIDThe RAID group identification number. The RAID group mustalready exist. You can create a RAID group with the creatergcommand (page 106).rgID specifies a number between 0 and the maximum number ofRAID groups supported by the RAID group storage system.The optional switches are:-aa auto_assignment (CX series only)Enables or disables auto-assignment functionality for the LUN.auto_assignment specifies functionality as follows:0 = Disables auto-assignment1 = Enables auto-assignment (the default)-cap capacitySets the capacity of usable space in the LUN. (The default is fullspace available.)-c cache-type (Not supported on AX4-5 series)You can enable either read or write caching, both read and writecaching, or neither type of caching for any LUN (logical unit)except a RAID 3 LUN or hot spare. For caching to occur,storage-system caching must also be enabled. Whether youshould use caching for a specific LUN depends on the RAID type.Recommendations for using caching for the different RAID types,see the Description section.cache-type specifies the type of caching used as follows:none = no cachingread = read cachingwrite = write cachingrw = read and write cachingThe default is read and write caching.84 EMC Navisphere Command Line Interface (CLI) Reference
