This week I opend a case with vmWare tech support about vCenter server sending out numerous false alerts. This time it sent out 400 emails about host #2 loosing its redundant connection to the SAN. (It had not). The techs solution was to upgrade the esx host from 4.0 update 1 to update 2. He had recommended that I apply the update to my 5 other ESX 4.0 u1 hosts. I upgraded three hosts before realizing that the vcenter server (and componets) should also be updated to update 2. Now I have 4 of 6 hosts updated, and not sure if I proceeded correctly.
Should I stop with the hosts and apply update 2 to the vcenter servers?
On line I have read much about the upgrade to 4.1 and migrating from 3.5/2.5 to v4.
Any adivse how to proceed would be appreciated.
