If less than 8GB of RAM is available use (default) boot option: Boot * The media is required to remain available while using the LiveDVD environment when booted to this option. * This option has a faster boot time but decreased live environment performance due to continued reading of the media. The 'Boot (run from RAM)' option copies the entire LiveDVD to RAM. * A minimum of 6GB RAM for this option is recommended. * For optimal use/functionality at least 8GB RAM is recommended. * After boot is complete the media is ejected and may be safely removed. * This option has increased boot time over other boot options but has greatly increased live environment performance. * If booting with less than 8GB of RAM, potential exists for filling the read-write overlay (device-mapper snapshot) and preventing most system operations. If encountered, reboot the LiveDVD. The LiveDVD environment logs in automatically to a graphical user interface desktop. To use actual username of 'root' (for use with ssh or OMSA, for example), the password is: dell. The LiveDVD non-root user is named 'omsauser' and has full access to sudo without password prompting. A simple way to obtain a root user shell is to double-click the gnome-terminal icon on the desktop and execute 'sudo su -'. Root's default password may be changed by running 'passwd' from CLI or 'sudo passwd' if not at a root shell. Root login is enabled for ssh. There is no firewall configured and selinux is disabled. OMSA can be launched by the icon on the desktop or by using https://localhost:1311. To login use the username: root and the password: dell. * May need to disable Firefox Offline Mode * Need to follow self-signed cert exception process - I Understand the Risks - Add Exception... - Get Certificate - Confirm Security Exception NetworkManager configures networking via DHCP when booted to any of the graphical environments (including the default boot option). If you need to set static IP(s), configure graphically from the NetworkManager applet or stop NetworkManager and configure networking using CLI. Connection via VNC to display :0 is available when booted to any of the graphical environments (including the default boot option). The folder /tmp/data is shared via httpd, vsftpd, samba, and nfs. It is also accessible using scp and sftp (as is the entire LiveDVD filesystem). There is a launcher for DSET on the desktop that will create a DSET report. This report is saved to /tmp/data which is accessible via ftp, http, nfs, and smb. Partitions and LogicalVolume filesystems (ntfs, vfat, ext2, ext3) on the local disks are automatically mounted read-only during boot. They will need to be manually mounted read-write if write operations to local-disk filesystem are required (such as editing config files on the local-drive filesystems). Pass parameters 'nolvmmount' and 'nodiskmount' to suppress. Local-disk swap is activated on boot. Pass parameter 'noswap' to suppress. Dell system updates can be run from this environemnt. SUU should work as well as individual DUP(s) from support.dell.com. Yum may be used to install additional packages from public CentOS repositories. Net-snmp is installed and available by default. This can be used to allow ITA to discover the server while it is booted to the LiveDVD environment. The snmpd.conf file will need to be configured by setting the appropriate IP and community name in two locations. Many common CentOS5 commands and utilities are available. Dell 32-Bit Diagnostics are now available from the boot menu. * MPMemory is included with the diagnostics. * Multiple versions are available that should cover most of the more recent PowerEdge platforms. * To identify which release supports each product, navigate to http://support.dell.com and use the search feature with this syntax: EL<####A#>.bin where <####A#> is one of the versions listed in the boot menu (example: EL5154A0.bin). Follow the link to the [Download] option and click on "Compatibility" to see the platforms supported.
