Managing Alarms and Events

Domain alarm table entries

Thealarmstringsarebasedontheassociatedsensorevents.Textwithinthealarmstring

indicatestheFRUlocation,sensornumber, andseverityofthesensorevent.Thereference

manualsforeachmodulecontaindetailedinformationontheirassociatedsensors.

Thedomainalarmtable(DAT)canholdamaximumof1024alarmentries.Thealarmentries

includesystemalarms,whicharegeneratedautomatically,andanyuser‐definedalarms.

Assigning event severities

Theeventsgenerate dbysensorsareassignedseveritiesautomatically,butyoucanoverride

thedefaultsettingsbyassigningnewseveritiestospecificeventsgeneratedbyindividual

sensors.Youcanassignseveritiestodiscrete,digital,andOEMsensors(withtheexceptionof

IPMBsensors).

Toassignseverities,addentriestotheShelfManageralarmconfigurationfile

(/etc/shmgralarm.conf)ontheShelfManagermoduleortheSCMhostingtheactiveShelf

Manager.Eachentryappliestoasinglesensor,althoughthesensormayapplytomultipleof

thesametypeofFRUintheshelf.Forexample,achangetotheseverityofafansensorevent

wouldapplytoallofthefansintheshelfifthefansareidenticalandarerunningthesame

•Thepresenceofanalarmandthealarmseverityinthedomainalarmtable.Critical,major,
