5-97container Commandscontainer set cacheTo set cache parameters for a specific array, use the containerset cache command. You can use this command only if a nativeoperating system’s file system—for Windows NT/Windows 2000(basic disk only)/Windows XP (basic disk only), NTFS, or FAT—resides on the array. In fact, the CLI prevents you from setting cacheparameters if the array: Is an array involved in a reconfiguration operationThe CLI disables the cache parameters on the array involved ina reconfiguration operation. The CLI re-enables the cacheparameters (assuming they were previously set) on the arraywhen the reconfiguration operation completes.The controller provides two global cache buffer pools available toarrays: a volatile read-ahead cache and a nonvolatile NVRAM write-back cache. Collectively, these global caches are referred to as thearray cache.The container set cache command allows you to set severalcharacteristics associated with the array cache. These characteristicsare embodied in the switches for the command.NotesSome controllers may not support the NVRAM write-back cache.Additionally, some controllers may not support the ability to enablethe NVRAM write-back cache.Syntaxcontainer set cache [/read_cache_enable{=boolean}}[/write_cache_enable{=boolean}] {container}
