T025: Power Supply Hardware Failure
Description GUI Description: A defective power supply has been detected.
Explanation: Power supplies report four failure conditions that are
considered to be a hardware failure within the supply: Fan Fail, Over Temp,
DC Fail and Over Current. These failures can occur in both single and
redundant power supply control modules and any expansion module with a
power supply.
Detection Scenarios Regular polling between Library Control Blade and power supply is not
successful.
Root Causes
1. Detected fan failure in the supply.
2. Detected over temp condition in the supply.
3. Detected DC failure in the supply.
4. Detected over current failure in the supply.

T026: Primary Key Server Failover
Description GUI Description: The library performed a successful communication failover
to the secondary key server.
Explanation: The Key Management feature of this library allows the user to
connect 2 key servers for redundancy. If communication to the primary
server is interrupted, the library will automatically switch or failover to the
secondary server. This RAS ticket will be generated to notify the user of this
failover event.
Detection Scenarios
v When the library detects that it can no longer communicate with the
primary key server and automatically switches to the secondary key
server.
Root Causes
1. Primary Key Server is not connected properly.
2. Primary Key Server is not configured properly.
3. Library Ethernet settings are not configured properly.
