MegaCLI Managed RAID Controllers

Description

This connector enables hardware monitoring for LSI RAID controllers in Oracle/Sun Solaris systems, and in IBM servers with EXP3000 external bays. This connector relies on MegaCli.

hardware ibm linux raid solaris sun

Enterprise Connector

This connector requires the Enterprise edition of MetricsHub.

Supersedes

This connector supersedes:

• SunIostat
• SunIostatNonSun
• Director52ServeRAIDLinux

Target

Typical platform: Sun/Oracle Servers

Operating systems: Oracle Solaris, Linux

Prerequisites

Leverages: MegaCli (LSI) managed RAID card

Technology and protocols: Commands

This connector requires advanced privileges on the managed host for the command below:

• MegaCli

This connector therefore needs to run as root or you need to configure a privilege-escalation mechanism like sudo on the managed host to allow the monitoring account to run the command listed above.

Sample of /etc/sudoers to allow the above command to be run as root by the metricshub account:

metricshub ALL=(root) NOPASSWD: MegaCli

Examples

CLI

metricshub HOSTNAME -t solaris -c +SunMegaCli --ssh -u USER --sudo-command-list MegaCli

metricshub.yaml

resourceGroups:
  <RESOURCE_GROUP>:
    resources:
      <HOSTNAME-ID>:
        attributes:
          host.name: <HOSTNAME> # Change with actual host name
          host.type: solaris
        connectors: [ +SunMegaCli ] # Optional, to load only this connector
        protocols:
          ssh:
            username: <USERNAME> # Change with actual credentials
            password: <PASSWORD> # Encrypted using metricshub-encrypt

Connector Activation Criteria

The MegaCLI Managed RAID Controllers connector will be automatically activated, and its status will be reported as OK if all the below criteria are met:

• The device type must be one of: SunOS, Solaris, Linux
• The command below succeeds on the monitored host:
  • Command: MegaCli -v -NoLog
  • Output contains: Exit Code: 0x00 (regex)
• The command below succeeds on the monitored host:
  • Command: MegaCli -AdpAllInfo -aALL -NoLog
  • Output contains: Exit Code: 0x00 (regex)
• The command below succeeds on the monitored host:
  • Command: MegaCli -PDList -aALL -NoLog
  • Output contains: Exit Code: 0x00 (regex)
