I have A IBM blade center with 2 lames , one san DS4700 , and 14 VM machines W2000, W3ks, Suse , Red Hat .
RecentIy I have upgrade my VI3 standard to VI enterprise and I have implemented VM Ha and DRS weeks .
I Upgrade my Virtual center and after i upgrade using the iso method my 2 hosts from V3.5 to V3.5u3 . 2 days after the migration , all the VM machines of the 2 hosts shut down without event .
I have no logs on my blade; my switch Fc . I think it could come from VM HA which has an automatic reply when one host detect isolation problem . The host shut down the VM machines .
Do you know where i must look to verify my hypothese .
