Note: The storage system generates a SIM when the cache destage batteries
are not charged to at least 50%. The LEDs on the front panel of the cache
boards also show the status of the batteries.
Long term array storage
While connected, the cache destage batteries will completely discharge in two
to three weeks without power applied. If you do not use a HUS VM for two
weeks or more, ask technical support to move the batteries to a storage
system that is being used, or turn the storage system on to standby mode for
at least 3 hours once every two weeks.
If you store the system for more than two weeks and do not disconnect the
cache destage batteries, when you restart the system, the batteries will need
to charge for at least 90 minutes before the cache will be protected. To
prevent the batteries from discharging during long term storage, call
technical support and ask them to disconnect the battery jumpers on the
cache boards.
