opachassisanalysis

(Switch) Performs analysis of the chassis.

The opachassisanalysis tool checks the following for the Intel(R) Omni-Path Fabric Chassis:

opachassisanalysis [-b|-e] [-s] [-d dir] [-F chassisfile]
[-H 'chassis']

Produces full help text.

Specifies the baseline mode. Default is the compare/check mode.

Evaluates health only. Default is the compare/check mode.

Saves history of failures (errors/differences).

Specifies the top-level directory for saving baseline and history of failed checks. Default is /var/usr/lib/opa/analysis

Specifies the file with the chassis in the cluster. Default is /etc/opa/chassis

Specifies the list of chassis on which to execute the command.

opachassisanalysis

The following environment variables are also used by this command:

List of chassis, used if -F and -H options are not supplied.

File containing list of chassis, used if -F and -H options are not supplied.

Top-level directory for baselines and failed health checks.

List of commands to issue during analysis, unused if -e option supplied.

Single command to issue to check overall health during analysis, unused if -b option supplied.

Intel recommends that you set up SSH keys for chassis (see opasetupssh ). If SSH keys are not set up, all chassis must be configured with the same admin password and the password must be kept in the /etc/opa/opafastfabric.conf configuration file.

The default set of FF_CHASSIS_CMDS is:

showInventory fwVersion showNodeDesc timeZoneConf timeDSTConf

snmpCommunityConf snmpTargetAddr showChassisIpAddr showDefaultRoute

The commands specified in FF_CHASSIS_CMDS must be simple commands with no arguments. The output of these commands are compared to the baseline using FF_DIFF_CMD. Therefore, commands that include dynamically changing values, such as port packet counters, should not be included in this list.

FF_CHASSIS_HEALTH can specify one command (with arguments) to be used to check the chassis health. For chassis with newer firmware, the hwCheck command is recommended. For chassis with older firmware, a benign command, such as fruInfo, should be used. The default is hwCheck. Note that only the exit status of the FF_CHASSIS_HEALTH command is checked. The output is not captured and compared in a snapshot. However, on failure its output is saved to aid diagnosis.

The opachassisanalysis tool performs its analysis against one or more chassis in the fabric. As such, it permits the chassis to be specified using the -H, -F, CHASSIS, chassis_file or opafastfabric.conf. The handling of these options and settings is comparable to opacmdall -C and similar FastFabric Toolset commands against a chassis.

All files generated by opafabricanalysis start with chassis. in the file name.

The opachassisanalysis tool generates files such as the following within FF_ANALYSIS_DIR. The actual file names reflect the individual chassis commands that have been configured through the FF_CHASSIS_HEALTH and FF_CHASSIS_CMDS parameters:

Health Check

•
latest/chassis.hwCheck Output of hwCheck command for all selected chassis

Baseline: During a baseline run, the following files are also created in FF_ANALYSIS_DIR /latest.

Full Analysis: The following .diff files are only created if differences are detected.

If the -s option is used and failures are detected, files related to the checks that failed are also copied to a time-stamped directory name under FF_ANALYSIS_DIR.

Based upon showInventory :

Based upon fwVersion:

•
Changes to primary or alternate FW versions installed in cards in chassis.

Based upon showNodeDesc:

•
Changes to configured node description for chassis. Note changes detected here would also be detected in fabric level analysis.

Based upon timeZoneConf and timeDSTConf:

•
Changes to the chassis time zone and daylight savings time configuration.

Based upon snmpCommunityConf and snmpTargetAddr:

•
Changes to SNMP persistent configuration within the chassis.

The following Chassis items are not checked against baseline:

•
Changes to the chassis configuration on the management LAN (for example, showChassisIpAddr, showDefaultRoute). Such changes typically result in the chassis not responding on the LAN at the expected address that is detected by failures that perform other chassis checks.

Based upon hwCheck:
