Applies to

BVQ Version: 2021.H1.3 and above

Procedure

The Postgres DB on VIO servers which the HMC queries to get various system information (like virtual networks, virtual storage, etc.) is broken or Postgres service (vio daemon) is not running. This causes HTTP-500 error messages on both, the HMC and BVQ scanner.

The issue can be fixed using the following commands on the VIOS:

expand...

ssh padmin@${vios}
$ oem_setup_env
# stopsrc -s vio_daemon
# /usr/sbin/slibclean
# rm -rf /home/ios/CM
# startsrc -s vio_daemon -a '-d 4'
