Managing and Recovering a Remote System 101
Why are the remote racadm and
Web-based services unavailable
after a property change?
It may take several minutes for the remote racadm
services and the Web-based interface to become
available again after a reset of the DRAC 4 Web
server
The DRAC 4 Web server is reset after the
following occurrences:
• When the cfgRacTuneHttpsPort property is
changed (including when a config
- f < config
file
> changes it)
• When
racresetcfg is used
• When the DRAC 4 is reset
When accessing the DRAC 4
Web-based interface, I get a
security warning stating the
hostname of the SSL certificate
does not match the hostname of
the DRAC 4.
DRAC 4 includes a default DRAC 4 server
certificate to ensure network security for the
Web-based interface and remote racadm features.
When this certificate is used, the Web browser
displays a security warning because the default
certificate is issued to RAC default certificate
which does not match the host name of the
DRAC 4 (for example, the IP address). To address
this security concern, upload a DRAC 4 server
certificate issued to the IP address of the DRAC 4.
When generating the certificate signing request
(CSR) to be used for issuing the certificate, ensure
that the common name (CN) of the CSR matches
the IP address of the DRAC 4 (for example,
192.168.0.120). See "Securing DRAC 4
Communications Using SSL and Digital
Certificates" for more information about
generating CSRs and issuing certificates.
