Instructions

Dekrypter centrale dumpfiler og opret supportpakke

Forudsætninger

  • SSH-adgang til ESXi-værten, der oplevede PSOD.
  • vSphere version 7.x eller nyere.

Procedure

  • Opret forbindelse til den berørte ESXi-vært via SSH.
  • Kontrollér, om hver enkelt kerne dumper ind /var/core er krypteret.
  • Hvis den er krypteret, dekrypteres kernedumpfilen.
  • Opret en ny supportpakke.
  • Upload supportpakken direkte til analysen 

Trinvise kommandoer

# SSH to the ESXi host
$ ssh root@[ESXI_HOST_IP]

# Verify encryption status of the first core dump
crypto-util envelope describe --offset 4096 /var/core/vmkernel-zdump.1

# Decrypt the first core dump if it is encrypted
crypto-util envelope extract --offset 4096 /var/core/vmkernel-zdump.1 /var/core/unenc-vmkernel-zdump.1

# Decrypt additional core dump files (repeat for each .zdump file)
crypto-util envelope extract --offset 4096 /var/core/vmkernel-zdump.2 /var/core/unenc-vmkernel-zdump.2

# Create a new support bundle
vm-support
vm-support -w use the -w to specify loaction example: ( vm-support -w /vmfs/volume/DATASTORE_NAME )
# The default bundle location is:
/var/tmp/ /var/log/ depending on which loacation has the most space
Advarsel: Dekryptering af kernedumps kan afsløre følsomme kundedata. Håndter de ukrypterede filer sikkert, og slet dem, når supportpakken er oprettet.
