container Commands container set cache To set cache parameters for a specific array, use the container set cache command. You can use this command only if a native operating system's file system (for Windows, NTFS, or FAT) resides on the array. The CLI prevents you from setting cache parameters if the array is involved in a reconfiguration operation. The CLI disables the cache parameters on the array involved in a reconfiguration operation. The CLI re-enables the cache parameters (assuming they were previously set) on the array when the reconfiguration operation completes. The controller provides two global cache buffer pools available to arrays: a volatile read-ahead cache and a nonvolatile NVRAM write-back cache. Collectively, these global caches are referred to as the raw array cache. The container set cache command allows you to set several characteristics associated with the raw array cache. These characteristics are embodied in the switches for the command. Notes Some controllers may not support the NVRAM write-back cache. Additionally, some controllers may not support the ability to enable the NVRAM write-back cache. Syntax container set cache [/ read_cache_enable{=boolean}} [/ unprotected{=boolean}] [/write_cache_enable{=boolean}] {container} Parameters {container} Specifies the ID number (0 to 63) of the array on which you want to set cache parameters. 3-91
