3.10 Power Down
The enclosure can be powered down at any time and if cached contents are present (refer to the Cache
Active LED on the RAID module), they will be preserved by the internal battery. If the enclosure is left in
this state for extended periods then the batteries will discharge and the cached data will be lost. It is
therefore recommended that, especially if the unit is to be powered down for extended periods, the
controller is shut down prior to powering off the enclosure.This will ensure that the cache is flushed to disc
and will prevent the battery from being discharged. Discharged batteries may also result in reduced
performance when the array is again powered up, because the write-back cache will be disabled until the
batteries are fully charged.
1 Shut down is requested at the GUI interface, please refer to StorView Storage Manager Software RAID
Module User Guide.
2 To power the Enclosure down, remove AC power at the power source.
