OVERVIEW

Elesai is a wrapper around LSI's MegaCli utility that provides access to common types of information about the RAID controllers via a show action without the need to speak martian. It is a line-oriented tool so that it can be combined with other Unix command-line tools to process and manipulate the data (i.e., sed, awk, and friends). It also provides a check action (currently as a Nagios plugin in both active and passive modes) which monitors the health of the array and its components and reports it accordingly (this is not yet configurable).

SYNOPSIS

elesai [global-options] <action> [action-options] [<component>]

where:

• <action> is one of show or check
• <component> (for show action) is one of
  • adapter
  • virtualdrive (or vd)
  • physicaldrive (or pd)
  • bbu

Global options include:

• -d, --debug: enable debug mode
• -f, --fake DIRECTORY: specifies path to directory containing output of MegaCli invocations:
  • adpallinfo_aall: output from MegaCli -adpallinfo -aall -nolog
  • ldlist_aall: output from MegaCli -pdlist -aall -nolog
  • ldpdinfo_aall: output from MegaCli -ldpdinfo -aall -nolog
  • adpbbucmd_aall: output from MegaCli -adpcbucmd -aall -nolog
• -m, --megacli MEGACLI: path to MegaCli binary (if noth in $PATH)
• -a, --about: display general information about elesai
• -V, --version: display elesai's version

The <check> can have options specific to itself:

• -M, --monitor MONITOR: Monitoring system (default: nagios)
• -m, --mode [active|passive]: Monitoring mode
• -H, --nsca_hostname HOSTNAME: NSCA hostname to send passive checks
• -c, --config CONFIG: Path to Senedsa (send_nsca) configuration
• -S, --svc_descr SVC_DESCR: Nagios service description

Elesai uses Senedsa for Nagios passive check submission, which can use a configuration file to set options. Additionally, it will invoke MegaCli with sudo if not run by root.
