Chapter 5: System Monitoring

This Chapter describes the devices used to monitor the 2Gb SANbloc Series. The location of the monitoring LEDs and how to interpret them is described.

Overview

The front mounted LS module is the main monitoring device of the 2Gb SANbloc Series. This module is comple- mented by status and fault LEDs, mounted on all the major components of the enclosure, such as, disk drives, power supplies, Advanced Cooling Modules (ACMs), and RAID Controller. All these monitoring devices are discussed in the following sections.

LS Module

The LS Module (Loop Resiliency and SES Module) provides monitoring and control for the 2Gb SANbloc Series. The module reports status and receives control infor- mation over the Enclosure Services Interface (ESI) port of any of the fourteen disk drives installed in the enclosure. The LS Module also provides loop resiliency for the Fibre Channel loop (in the form of Port Bypass Circuits).

The 2Gb SANbloc Series contains one LS Module as standard. However, a second optional LS Module is available to provide active/passive fail-over for the enclosure services communication, and to provide a second Fibre Channel Loop. Only one LS Module communicates (using ESI communication) with the host system at any one time, but both LS modules will continuously monitor the
