Product Overview
Note Using software to perform a shutdown is the preferred method
because confirmation of a successful shutdown is reported to the
operator.
If the power fails or if you unplug the power cords without performing a
shutdown, the following sequence will occur when the array is powered on
again:
1 The array will attempt to retrieve the maps from cache and determine if they
are valid.
2 If the maps are not valid, the array will retrieve the maps from the image
disks.
Note If power to the array is lost by any means other than by moving
the power/standby switch to the standby position, the array will
not have time to perform a successful shutdown. In this case, a
fully charged battery can sustain NVSDRAM contents for 3
days.
