To enable a container’s NVRAM write-back cache, use the

container set cache command with the /write_cache_enable

switch, as in the following example. In the example, the

/write_cache_enable=TRUE switch enables the write-back cache on

container 0. The /unprotected=FALSE switch enables the NVRAM

write-back cache only if a battery is present and its status is Ok.

HPN0> container set cache /write_cache_enable=TRUE

/unprotected=FALSE 0

Executing: container set cache /write_cache_enable=TRUE

/unprotected=FALSE 0

After running the container set cache command to enable a

container’s NVRAM write-back cache, use the container show

cache command to display information about the container’s

cache, as in the following example. In the example, the Write Cache

Setting item indicates ENABLE WHEN PROTECTED, which

means that the container’s NVRAM write-back cache is enabled if a

battery is present and its status is OK.

HPN0> container show cache 0

Executing: container show cache 0
