  • VAMI UI will report the failure as "Exception occured in postInstallHook"

VMware vCenter Server 7.0.x


This failure is due to stale administrator credentials that are left over from the initial installation or a previous major upgrade.


This is a known issue and is fixed in VC 7.0U3g

To workaround the issue follow the below steps

1.  Take an offline snapshot (vCenter VM powered off) of vCenter Server ( All nodes in case of Enhanced Linked Mode).
2.  Power on vCenter VM and make sure vCenter UI is accessible and inventory is loaded successfully.
3.  Run commands to clear the SSO credentials
/bin/install-parameter -s vmdir.password
/bin/install-parameter -s vmdir.username
4. Try the vCenter upgrade again.

5. After successful patching, run the following to reset the vmdir.username install parameter

NOTE:  The aforementioned workaround will cause future PNID change operations to fail unless you set the install-parameters for vmdir.username manually (it is not necessary to set vmdir.password):
/bin/install-parameter -s vmdir.username administrator@<your_SSO_domain_here>
/bin/install-parameter -s vmdir.username [email protected]
