Isilon: Smartconnect Service IP Address (SSIP) forsvinner på alle konfigurerte VLAN-grensesnitt etter å ha utført OneFS 8.2-oppgradering

摘要: Denne artikkelen beskriver en hendelse der SSIP mangler på alle grensesnitt som er konfigurert med VLAN når du oppgraderer til 8.2.

症状

Når du utfører en oppgradering til OneFS 8.2, er smartconnect-tjenestens IP-adresse (SSIP) ikke lenger tilgjengelig for sonenavnspørringer og belastningsfordeling for alle grensesnitt som er konfigurert med VLAN-merking. 
MERK: Dette problemet gjelder ikke for alle delnett som er konfigurert med SSIP og VLAN-merking.  I tillegg gjelder ikke dette for andre oppgraderingstyper eller -versjoner.  Dette gjelder bare ved oppgradering til 8.2.
For å illustrere problemet gjenspeiler en intern reproduksjon hvordan problemet utløses, og hvilke kriterier som er nødvendige –
>> Vi kan se at SSIP finnes på alle grensesnitt (169.168.1.9, 169.168.10.9, 169.168.20.9):

原因

Når du oppgraderer til 8.2, deles Flexnet-konfigurasjonsfilen (flx_config.xml) opp i mindre, smaltere informasjonsbiter.  En ny mappe opprettes som nodeinfo, som hver nodes grensesnitt og statusinformasjon blir gitt til.  Under oppgraderingen hentes imidlertid ikke vlan-informasjon, og utelater dermed enhver vlan-konfigurasjon i hver nodeinfo-fil.  Når oppgraderingen er utført, prøver Smartconnect å lese fra nodeinfo-filene og kan ikke registrere noen vLAN-detaljer for å tilordne SSIP. 
Mens feilsøking isi_smartconnect_d, kan vi se følgende feil i loggene: 
2019-07-15-T12:46:12:DEBUG:0x80c612010:NodeInterfaceGetVlanNic_inlock():nodeinfo.c:1281: Error STATUS_NOT_FOUND (0xc0000225)

解决方案

Dette problemet ble observert bare ved oppgradering til 8.2.0. Problemet ble løst i 8.2.1.0 og nyere. Eventuelle oppgraderinger til nyere versjoner enn 8.2.0 er ikke berørt.  Hvis du mistenker at du er berørt av dette problemet, kan du kontakte kundestøtten og referere til denne kb-en før du fortsetter til trinnene nedenfor.
  1. For å løse problemet må konfigurasjonene flx_config.xml og nodeinfo være tvunget til å endre seg.  Dette kan utløses ved å aktivere og deaktivere smartconnect-feilsøkingslogging.
Slik aktiverer du feilsøkingslogging: 
# isi_sc_log_level -l debug
Slik endrer du logging til informasjon: 
# isi_sc_log_level -l info
Kontroller at IP-adressen er returnert, og at prosessene kjører: 
# isi_for_array ifconfig | grep <SSIP>
# isi_for_array -s ps auwx | egrep "(smartconnect|dnsiq)" | grep -v grep
MERK: Omstart av daemoner har ikke løst dette problemet.  Daemoner inkluderer isi_dnsiq_d, isi_smartconnect_d og isi_flexnet_d.
