Navisphere Command Line Interface (CLI) Reference - VMware Communities

LUN Expansion (MetaLUN) CommandsYou can expand only the last component of an existing metaLUN.In this case, the -type S switch restripes any existing data acrossthe original LUNs in the component and any new LUNs that youadd. The new LUNs become part of that metaLUN component.The following command switches are supported with NavisphereExpress and are mandatory:-base number|WWNSpecifies the source LUN or metaLUN you want to expand. Youcan specify the base number or World Wide Name of the LUN.-cap numberSpecifies the additional storage capacity you can add to the LUNor metaLUN. The size qualifier for the -cap number is the -sqswitch.-sq tb|gb|mbSpecifies the size qualifier for the capacity of the metaLUNcomponent.where:tb equals terabytes, gb equals gigabytes, and mb equalsmegabytes.For example, if you are expanding a 20 GB LUN, and specify-sq gb -cap 20 in the command, the resulting metaLUN is 40 GB.The optional switch for Navisphere Express is:-percent numberSpecifies the amount of additional storage you want to expand by,as a percent of the current size of the LUN. The number shouldalways be greater than 0. This switch can be used instead of -sqand -cap number switches.For example, if you are expanding a 20 GB LUN, and specify-percent 50 in the command, the resulting metaLUN is 30 GB.Note: For AX4-5 series systems running Navisphere Express, the defaultexpansion type is concatenate. The expansion type, stripe is not supported onAX4-5 series systems.The AX4-5 series systems support only an expansion rate of high.337
