This action applies only to the control domain. Determine the domain that you are currently securing. # virtinfo Domain role: LDoms control I/O service root The current domain is the control domain, which is also an I/O domain, the service domain, and a root I/O domain. If the current domain is not the control domain, this check does not apply. Determine if vnsd is in use. # svcs vntsd STATE STIME FMRI online Oct_08 svc:/ldoms/vntsd:default If the state is not "online", this is not applicable. Determine if a role has been created for domain console access. # cat /etc/user_attr | grep solaris.vntsd.consoles rolename::::type=role;auths=solaris.vntsd.consoles;profiles=All;roleauth=role If a role for "vntsd.consoles" is not established, this is a finding.

The root role is required. This action applies only to the control domain. Determine the domain that you are currently securing. # virtinfo Domain role: LDoms control I/O service root The current domain is the control domain, which is also an I/O domain, the service domain, and a root I/O domain. If the current domain is not the control domain, this action does not apply. Create a password-controlled role that has the solaris.vntsd.consoles authorization, which permits access to all domain consoles. # roleadd -A solaris.vntsd.consoles [role-name] # passwd [role-name] Assign the new role to a user. # usermod -R [role-name] [username]

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
