Redundant Electronics Overview
The optional redundant electronics (RE) feature provides failover protection for the
library controller. If the library controller or drive controller experiences errors,
operations can switch to the standby controller. The library controller and drive
controller installed on the same side of the card cage are always switched as a pair.
RE allows an Oracle support representative to replace a faulty card while the library is
online and provides minimal disruption during firmware upgrades.

Requirements for Redundant Electronics
■
Two library controller (HBC) cards
■
Two drive controller (HBT) cards
■
Minimum SL3000 firmware version FRS_3.0 and SLC version 5.00
Note:
Any reference to the HBC card also refers to the HBCR card.
Note:
To enable ADI mode, both cards must be high-memory HBTs.
If using Media Validation, Oracle recommends both HBT cards are
high-memory.
