LUN Expansion (MetaLUN) Commands-elszmDisplays the element size multiplier for all metaLUNs on thestorage system (see page 334).Issuing the -elszm command with a metaLUN name, number orWWN displays the element size multiplier for the specifiedmetaLUN (see page 334).-isredundantDisplays the redundancy of all metaLUNs on the storage system -Yes if it is redundant; No if it is not redundant.Issuing the -elszm command with a metaLUN name, number orWWN displays the redundancy of the specified metaLUN - Yes ifit is redundant; No if it is not redundant.-percentexpDisplays the percent complete of the stripe expansion process ofall base LUNs or metaLUNs on the storage system.Issuing the -percentexp command with a metaLUN name,number or WWN displays the percent complete of the stripeexpansion process of the specified base LUN or metaLUN.-rhist*Returns read histogram information for all metaLUNs on thestorage system.Note: A read histogram is an array of 10 locations that contain thenumber of reads. Element n of the array contains the number of readsthat were larger than or equal to 2n-1 and less than 2n blocks in size. Forexample, the first bucket contains the number of 1 block reads, thesecond contains the number of 2-3 block reads, the third contains thenumber of 4-7 block reads, and so on. The -rhist switch also displays thenumber of read histogram overflows, which are the number of reads thatwere larger than 512 blocks.Issuing the -rhist command with a metaLUN name, number orWWN returns the read histogram for the specified metaLUN.344 EMC Navisphere Command Line Interface (CLI) Reference
