Before you remove a battery backup unit, review the possible effects
that a battery backup unit service action can have on your storage unit.
Removing and replacing a
battery backup unit might result in the following effects:
- While a battery backup unit is out of the enclosure slot, the enclosure
is more susceptible to single point of failure errors.
- Removing a battery backup unit that does not have a lit error indicator
results in a processor card failover.
- Removing the battery backup unit might result in loss of access to improperly
configured host systems.
- Removing a battery backup unit without immediate replacement by either
another battery backup unit or a battery backup unit blank might result in
the overheating of the enclosure.
- The storage unit might experience performance degradation while a battery
backup unit is missing from its slot.
