LUN Expansion (MetaLUN) CommandsNote: A write histogram is an array of 10 locations that contain thenumber of writes. Element n of the array contains the number of writesthat 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 writes, thesecond contains the number of 2-3 block writes, the third contains thenumber of 4-7 block writes, and so on. The -whist switch also displaysthe number of write histogram overflows, which are the number ofwrites that were larger than 512 blocks.Issuing the -whist command with a metaLUN name, number orWWN returns the write histogram for the specified metaLUN.OutputMeta-LUN Name: LUN30Meta-LUN WWN:60:06:01:6D:35:0A:00:00:FC:35:5B:8C:66:60:D7:11Meta-LUN Number: 30Default Owner: SP ACurrent Owner: SP BMeta-LUN State: ENABLEDCan MetaLUN Be Expanded: YesExpansion Rate: MEDIUMPercent Expanded: 0Total Capacity (Blocks/Megabytes): 819200/400Actual User Capacity (Blocks/Megabytes): 819200/400Autoassign: NoIs Redundant: YesDrive Type: Fibre ChannelElement Size Multiplier: 40Bind Offset: 0Read Histogram [0] : 22Read Histogram [1] : 14Read Histogram [2] : 19Read Histogram [3] : 37Read Histogram [4] : 6Read Histogram [5]: 0Read Histogram [6] : 0Read Histogram [7] : 0Read Histogram [8] : 0Read Histogram [9] : 0Read Histogram Overflows: 45Write Histogram [0] : 22Write Histogram [1] : 22Write Histogram [2] : 22Write Histogram [3] : 22Write Histogram [4] : 22Write Histogram [5] : 22Write Histogram [6] : 22Write Histogram [7] : 22Write Histogram [8] : 22Write Histogram [9] : 22346 EMC Navisphere Command Line Interface (CLI) Reference
