SAN High Availability Planning Guide
Redundant FRUs (logic cards, port transceivers, power supplies, and cooling
fans) that can be removed or replaced without disrupting director, switch, or
Fibre Channel link operation.
A modular design that enables quick removal and replacement of FRUs
without the use of special tools or equipment.
Concurrent port maintenance. Director UPM cards and switch port
transceivers that can be removed, added, or replaced without interrupting
other ports or product operation. In addition, fiber-optic cables can be
attached to ports without interrupting other ports or product operation.
Beaconing to assist service personnel in locating a specific port, FRU,
director, or switch in a multi-switch environment. When port beaconing is
enabled, the amber LED associated with the port flashes. When FRU
beaconing is enabled, the amber (service required) LED on the FRU flashes.
When unit beaconing is enabled, the system error indicator on the product
flashes. Beaconing does not affect port, FRU, director, or switch operation.
Data collection through the associated Product Manager application to help
isolate system problems. The data includes a memory dump file and audit,
hardware, and engineering logs.
Status monitoring of redundant FRUs and alternate Fibre Channel data paths
to ensure continued director or switch availability in case of failover. The
HAFM application queries the status of each backup FRU daily. A backup
FRU failure is indicated by an illuminated amber LED.
SNMP management using the Fibre Alliance MIB that runs on the HAFM
server. Up to 12 authorized management workstations can be configured
through the HAFM application to receive unsolicited SNMP trap messages.
The trap messages indicate operational state changes and failure conditions.
SNMP management using the Fibre Channel Fabric Element MIB
(Version 3.1), Transmission Control Protocol/Internet Protocol (TCP/IP)
MIB-II definition (RFC 1213), or a product-specific MIB that runs on each
director or switch. Up to six authorized management workstations can be
configured through the associated Product Manager application to receive
unsolicited SNMP trap messages. The trap messages indicate operational state
changes and failure conditions.
