計画停電でvCenterを強制Power offせざるを得ず、起動後にvCenterにつながらない状態に...

503 Service Unavailable (Failed to connect to endpoint: [N7Vmacore4Http20NamedPipeServiceSpecE:0x7fc6705a4620] _serverNamespace = / _isRedirect = false _pipeName =/var/run/vmware/vpxd-webserver-pipe)

ここの手順で再起動を試みるも失敗、

どうやら、vCenter Server Appliance 6.0 Inventory Service データベースのリセットが必要そう。
