Basic Commands-d default-owner (Not supported on AX series)Changes the default owner of the LUN. default-owner specifiesownership as follows:0 = Changes ownership of the LUN to SP A1 = Changes ownership of the LUN to SP B-dp (AX4-5 series running Navisphere Manager and CX series only)Sets the default prefetch values.-i idle-thresh (Not supported on AX4-5 series and AX series)Sets the maximum number of I/Os that can be outstanding to aLUN and still have the LUN be considered idle. idle-threshspecifies the maximum number of I/Os. Used to determine cacheflush start time. Legal idle-thresh values range from 0 through 254.-mp max-prefetch-blocks (AX4-5 series running Navisphere Managerand CX series only)Sets the maximum number of disk blocks to prefetch in responseto a read request. max-blocks specifies the maximum number.-name newnameSets the LUN name. newname specifies the new name for theLUN. This switch applies only to storage systems running aversion of FLARE software that supports storage groupcommands. The LUN name is displayed in the UI and has noother purpose. You cannot use the LUN name as a CLI commandargument. You can assign the same name to multiple LUNs.Note: The -name switch applies only to shared storage systems.-pc max-prefetch-IO (AX4-5 series running Navisphere Manager andCX series only)Sets the maximum number of outstanding I/Os that the LUN canhave and still perform prefetching. max-IO specifies themaximum number of I/Os. Valid values are 0 through 100.-pd min-prefetch-size (AX4-5 series running Navisphere Manager andCX series only)Sets the prefetch disable size. min-size specifies, in blocks, the sizeof the smallest read request for which prefetching is disabled.Prefetching is disabled for all read requests whose size is equal toor larger than min-size. Valid values are 0 through 65534.94 EMC Navisphere Command Line Interface (CLI) Reference
