AIX HACMP failures

The following command gives you a good overview of the current status of the
HACMP clusters. This is run from the command line in AIX:
/usr/es/sbin/cluster/clstat
Alternately, you can use the smitty menus to accomplish the above.

Error indication and LED indicators

The DR550 SSAM Server is designed for client setup of the machine and for the
subsequent addition of most hardware features. The DR550 SSAM Server also
allows clients to replace service parts (Client Replaceable Unit). To accomplish this,
the DR550 SSAM Server provides internal LED diagnostics that identify the parts
that require service. Attenuation of the error is provided through a series of light
attention signals, starting on the exterior of the system (System Attention LED)
which is located on the front of the system and ending with an LED near the
failing Field Replaceable Unit.
For more information about Client Replaceable Units, including videos, see
http://publib.boulder.ibm.com/eserver.

System attention LED

The attention indicator is represented externally by an amber LED on the operator
panel and on the back of the system unit. The amber LED indicates that the system
is in one of the following states:
v Normal state, LED is off.
v Fault state, LED is on solid.
v Identify state, LED is blinking.
Additional LEDs on I/O components such as PCI-X slots and disk drives provide
status information such as power, hot-swap, and need for service.

Concurrent maintenance

Concurrent maintenance provides replacement of the following parts while the
system remains running:
v Disk drives
v Cooling fans
v Power subsystems
v PCI-X adapter cards
v Operator Panel

Indicators in IBM Director
