Navisphere Command Line Interface (CLI) Reference - VMware Communities

Basic CommandsSyntaxPrerequisitesOptionschglun is used with naviseccli (described on page 37) or navicli(described on page 45) as follows:chglun -l lun[-a auto-assign] [-c cache-type] [-d default-owner] [-dp] [-i idle-thresh][-mp max-prefetch-blocks] [-name newname][-pc max-prefetch-IO] [-pd min-prefetch-size] [-pf prefetch-type][-pm pf-size/mult] [-r rebuild-priority] [-rt retain-prefetch-data][-sm prefetch-segmnt-size/mult ] [-t idle-delay-time][-v verify-priority] [-w write-aside]For naviseccli, you must have a user account on the storage systemon which you want to execute the command.For navicli, you must have a user entry in the Navisphere agentconfiguration file.-l lunSpecifies which LUN to change. lun specifies the LUN number.This switch is required.The optional switches are:-a auto-assign (CX series only)Enables or disables automatic reassignment of LUN ownership toan active SP if an SP failure occurs.auto_assign specifies functionality as follows:0 = Disables auto-assignment for specified LUN1 = Enables auto-assignment for specified LUN-c cache-type (AX4-5 series running Navisphere Manager and CXseries only)Enables either read or write caching, both read and write caching,or neither type of caching for the LUN. For caching to occur,storage-system caching must also be enabled. Whether or not youshould use caching for a specific LUN depends on the RAID type.See the caching recommendations for different RAID types onpage 82.cache-type specifies the type of caching used as follows:none = no cachingread = read cachingwrite = write cachingrw = read and write caching93
