ran command esxcli --server yyy.yyy.yyy.yyy software vib install --depot=/vmfs/volumes/DATASTORE/VIBS/OM-SrvAdmin-Dell-Web-6.5.0-542907.VIB-ESX50i_A02.zip
and i got a Connect to yyy.yyy.yyy.yyy failed error, command did not prompt for creds. I tested with ping and it does respond. (same cmd window)
