On initial boot of a freshly deployed (Ubuntu) Linux appliance on VMware vSphere 5 the machine stopped working because of an inconsistent disk. According to the machine 255 days where passed without the disk being checked. After a file system check is forced the machine stops with an error UNEXPECTED INCONSISTENCY followed by fsck /  terminated with status 4.
During the installation of the VMware vSphere Web Client I had to provide vCenter Single Sign On Information. Since no additional accounts / groups where granted SSO admin privileges (see VMware vSphere 5.1 Documentation Center) the only account that had sufficient privileges was the default SSO admin user [email protected]. The credentials of this account are provided during installation of the vCenter Single Sign On Service.
Unfortunately the password of the default SSO admin account was unknown. In this article I’ll explain how to change the password of the default SSO admin account.
