Basic Commandssetcache (AX4-5 series running Navisphere Manager and CXseries only)Sets SP cache or RAID 3 size informationDescriptionThe naviseccli or navicli setcache command changes system cachingor RAID 3 settings on an SP. By using setcache with its variousswitches, you can enable, disable, and configure the cache. Cache sizeswitches do not affect a cache if that cache is enabled; you mustdisable the pertinent cache (-rc or -wc switches) before any sizeswitches will be effective.Note: The changes to caching properties may be delayed until you haveallocated memory and the standby power supply (SPS) is working. This maytake several minutes.Note: You can use the getsp command to discover SP memory and thegetcache command to discover cache settings.SyntaxPrerequisitesOptionssetcache is used with naviseccli (described on page 37) or navicli(described on page 45) as follows:setcache [-h high-watermark] [-hacv n] [-l low-watermark][-p page-size] [-r3a raid3-size-spa] [-r3b raid3-size-spb][-rsza read-cache-size-spa] [-rszb read-cache-size-spb][-rca read-cache-spa] [-rcb read-cache-spb][-wc write-cache] [-wsz write-cache-size] [-o]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.-h high-watermark (not supported on a single-SP AX4-5 series systemrunning Navisphere Manager)Sets the write cache high watermark. high-watermark specifies thepercentage of dirty pages, which, when reached, causes both SPsto begin flushing the cache. The default is 80 percent for CX3series and CX series.260 EMC Navisphere Command Line Interface (CLI) Reference
