Troubleshooting an Oracle Solaris 11 Installation

You might encounter some of the following issues during or after installing Oracle Solaris 11.

Monitoring the Live Media Startup Process

Switching to the text boot screen is useful, if you suspect that the system startup process is not proceeding normally. The text screen might contain informational messages or a request for user input. Switching to the text boot screen has no impact on the boot sequence, other than how the information is displayed on the screen. Initialization of the operating system continues and completes as normal.

To switch to a text boot, press any key a few seconds after the GUI boot screen appears and the progress animation begins. Note that after switching from the GUI boot to a text boot, there is no way to switch back to the GUI boot screen.

Troubleshooting Login and User Account Issues After an Installation

Boot the system in single-user mode.
1. When the boot sequence starts, and the GRUB menu is displayed, type e to edit the GRUB menu entries.
2. Select the kernel$ line, then type e to edit the entry.
3. Type -s at the end of the line to boot the system in single-user mode.
4. Press Return to go back to the previous screen, then type b to boot the system.
When prompted, log in as root with the root password.
After the system has booted, you can do any of the following:
- Display the existing user accounts and roles.
```
# cat /etc/user_attr
```
- Delete a user account.
```
# userdel username
```
- Create a new user account.
```
# useradd username
```
  1. Assign a password for the user name.
```
# passwd username
```
    You will need to type the password twice.
  2. Assign the root role to that user.
```
# usermod -R root username
```
To return to the installed system, type exit.
