ESX virtual machine error 156
i was trying to configure a NBU for taking ESX Virtual Machine Backups. i was reading all technotes and specially 318357. now reached a point where need help :)
my environment is:
-->NBU Master/media/emm Server 6.5.4 (Solaris 5.10)
-->NBU Media Server (Solaris 5.10) added to existing NBU(Master/media/emm) working functionally perfect.
-->fullfilled all requirements as Snapshot License etc
now for taking esx virtual machine backups,
-->installed Win Server 2003 (32 bit)
-->Virtual Centre 2.5 (configured datacentre --> esx) esx running Solaris machines
-->NBU Media Server 6.5.4 (working perfect)
-->Configured Storage Unit which is listed in Policies tab and working perfectly.
now, i am facing the error 156 "Snapshot error encountered" when run backup.
-->used policy Flashbackup-windows and followed step listed in the technote 318357.
--> also in policy i can't browse any esx/virtual machine,
-->infact in Policy--> in Client's tab when i click New --> and browse for Virtual machines ---> getting error " System error occured "
-->i have added the ESX (ipaddress and Hostname ) to the /etc/hosts file of Master, 2 Media Servers. pinging is perffect.
is there something which i missed, or what ? why i am not able to access ESX or Virtual machines ?
