PowerScale: On-Cluster Analysis -työkalun suorittaminen

Summary: Ohjeet IOCAn (Isilon On-Cluster Analysis Tool) käyttöön ja tulosten tulkintaan.

This article applies to This article does not apply to This article is not tied to any specific product. Not all product versions are identified in this article.

Instructions

Isilon On-Cluster Analysis (IOCA) -työkalu analysoi käynnissä olevan PowerScale-klusterin kunnon ja* auttaa* päivitysten suunnittelussa.

* IOCA: ta ei ole suunniteltu korvaamaan päivityksiin liittyvien asiakirjojen tarkistamista päivitystoimiin valmistautuessa. Lisätietoja on OneFS-päivityksen suunnittelu- ja prosessioppaassa:

Esittelyvideo on katsottavissa alla. Varmista aina, että käytät uusinta versiota, kun suoritat sitä klusterissa.
HUOMAUTUS: Tämän videon viittaukset käytettävissä oleviin suodattimiin voidaan viitata alla argumentteina tai suodattimina.

IOCA-työkalun uusin versio on ladattavissa Lightningista.
     
HUOMAUTUS: Uusin versio ladataan, vaikka latauspäivämäärä on vanhempi.
     
HUOMAUTUS: Kun olet ladannut ja siirtänyt klusteriin, sinun on purettava IOCA ja IOCA.sha256 pakkauksesta käyttämällä
tar -zxvf IOCA.tar


IOCA:n suorittaminen klusterissa:

  1. Varmista, että yhteys oikeaan klusteriin on muodostettu. Näytä klusterin sarjanumerot suorittamalla seuraava komento ja varmista, että palvelupyynnön sarjanumero näkyy luettelossa:
isi_for_array cat /etc/isilon_serial_number
  1. Luo hakemisto /ifs/data/Isilon_Support/ , jos sitä ei ole, ja vaihda se siihen suorittamalla seuraavat komennot:
mkdir -pv /ifs/data/Isilon_Support

cd /ifs/data/Isilon_Support
  1. Siirrä IOCAn uusin versio klusteriin /ifs/data/Isilon_Support/- hakemistoon:

  • Jos aiempi versio on olemassa, varmista, että se on uusin versio, suorittamalla alla oleva komento ja vertaamalla sitä ladattavissa olevaan versioon. Versio näkyy kuntotarkistuksen komentosarjan yläosassa.
perl IOCA -v
Suorita IOCA-työkalu ja lisää mahdolliset lisäargumentit. Seuraavassa esimerkissä päivitystä edeltävä tarkistus sisältää tarkistukset versioon 9.5.1.0 päivittämisestä ja näyttää päivityssuunnitelman suosituksen kuntotarkistuksen tulosten jälkeen:
perl IOCA -u 9.5.1.0
  1. Kerää tulokset ja lähetä ne palvelupyyntöön.
  2. Tarkista kaikkien tunnistettujen FAIL- tai WARN-viestien kuntotarkistukset mahdollisten ongelmien varalta.


IOCA: n tulosteiden tulkinta: 

Jos kutakin kuntotarkistuksen kohdetta varten havaitaan jotain, siihen liittyy yleensä tietokannan (KB) artikkeli. Tämä työkalu oli alun perin sisäisesti suunnattu työkalu, mutta jotkut sen esittämistä artikkeleista eivät ole vielä ulkoisesti käytettävissä. Työ on käynnissä, jotta nämä viitatut artikkelit olisivat ulkoisen yleisön käytettävissä.

Seuraavassa on esimerkki klusterin BMC- tai CMC-laitteiston valvonnan tarkistusvirheestä:
BMC/CMC Hardware Monitoring                       FAIL
  FAIL: Hardware monitoring issues detected on nodes: 2
  INFO: 3 nodes have out of date CMC firmware versions: 1-3
  INFO: Refer to KB489050 (https://support.emc.com/kb/489050) for details.

Tässä esimerkissä solmussa 2 on tilana FAIL, jossa on laitteiston valvontaongelmia. Se sisältää myös INFO-tiedot, jotka osoittavat, että CMC-laiteohjelmistoversiot ovat vanhentuneita solmuissa 1–3. Lopuksi se sisältää tietämyskannan artikkelin, joka sisältää ratkaisuvaiheet. 


Yhteensopivuustila

IOCAa käytetään samalla tavalla klustereissa, joissa on käytössä Compliance Mode, kuin ei-vaatimustenmukaisuustilan klustereissa. Sitä ei tarvitse käyttää sudolla. Compadmin-käyttäjän on kuitenkin oltava IOCA-komentosarjan omistaja, jotta hän voi suorittaa sen.

Seuraava on IOCA: n ja käytettävissä olevien argumenttien tai suodattimien käyttö:
