Recommended Action
Read Flash Cache is
working under a heavy load,
and therefore has skipped
some IOs. This is a
temporary error which
should resolve itself. If it
persists, try to balance the
Storage Pool contents
across more SDSs, or add
more cache cards.
IO has become stuck on the
cache device. Disable
caching on the device and
check the health of the
device, because it may be
faulty. If necessary, replace
the device.
There is not enough RAM
available on the server for
Read Flash Cache optimal
operation. Increase the
amount of available RAM.
The Read Flash cache
driver (xcache) is either not
installed, or was installed in
the wrong location. Install
the driver, and contact
Customer Support if the
problem persists.
Check RFcache state of all
disks in the pool and adjust
them so that all disks have
the same caching state.
Query the system to
determine what is not
consistent in the
configurations of the Read
Flash cache driver and the
SDS where the cache
device is located.
You tried to add a cache
device that does not exist.
Check and fix Read Flash
Cache configuration.
