When you install an Xsan configuration profile, you may see the following message:
A server administrator username and password are required to join SAN [SAN NAME].
If you enter an invalid user name and password, the profile doesn't install, and you see this alert message:
Profile installation failed.
Unable to open proxy session
To resolve this issue, enter the user name and password for an administrative user on your Xsan metadata controller (MDC). If your Xsan has more than one MDC, use the admin user name and password of the first MDC listed in the profile's "Configuration Servers" list.
