LUN Expansion (MetaLUN) CommandsCorrect application of the bindoffset should result in improvedperformance. Use a decimal, not hexadecimal, number forsector-number. If you do not specify a bind offset value, it defaultsto 0.-cap capacitySpecifies the capacity of usable space in the metaLUN. Thecapacity must be smaller than the maximum capacity of themetaLUN components, and greater than or equal to the currentcapacity (user capacity of the LUN or metaLUN before addingLUNs). The default value is the maximum capacity of themetaLUN (total capacity of the existing LUNs and any newLUNs).Note: If you want to expand a LUN or metaLUN that is participating in aSnapView (snapshot or clone), MirrorView, or SAN Copy session, youmust use the -nogrow switch with the -expand -cap command. Thiscommand expands the capacity of the LUN or metaLUN to the specifiedvalue, but keeps the available user capacity of the base (LUN ormetaLUN) the same as it was before adding LUNs. In order for the hostto have access to the added capacity, you must wait for the session tocomplete and then follow the instructions in “Using the added capacityof an expanded SnapView, MirrorView or SAN Copy LUN” on page 350.-defaultowner A|BSpecifies the SP that will assume ownership of the metaLUNwhen the storage system is powered up. If you do not specify adefault owner, it defaults to the owner of the base LUN.-elszm elementSizeMultiplier (Not supported on AX4-5 series systemsrunning Navisphere Manager)Sets the stripe element size for a metaLUN component. Youdetermine this by multiplying the stripe size of the first LUN ineach component (stripe size of the first LUN = stripe element sizeof the LUN multiplied by the number of disks in the LUN) by theelement size multiplier. Valid multiplier values are 1 through 255.The default multiplier is 40.Note: We recommend that you leave the element size multiplier value at40.334 EMC Navisphere Command Line Interface (CLI) Reference
