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.
