(1) Insert the USB drive, On Dell systems, select F12 to enter the bootup options---select usb device. After the initial grub startup (before the hardware detect)--REMOVE the USB drive to avoid recognition during the LVM partitioning scheme.

(2) Select erase entire disk LVM option.

• Note: the boot partition is the only partition outside of the LVM partition

as it is not readable by the Grub boot loader.

(3) Create the 'caladmin' account/password.

• Use the pwgen -s 10 1 utility to generate the local passowrd.

(4) Take notce of the availability of mutiple console(s) that can be accessed using the ctrl+alt+F1-F7. These can be used to monitor logs and issue commands such as restarting services. Make sure to logout of all consoles when finished.

(5) During the installing, we may come across a slow network connection or an inaccessible package--reissuing the install command using the menu allow for a correct/clean re-download of the files.

• During the early tests of the auto-installer, we

ran into issues with incompatible kernel/init files with respect to the files on the USB drive, the CAL script will stop with the error:

 "No kernel modules were found. This problem is due to a mismatch between
  the kernel used by this version of the installer and the kernel
  available in the archive..."

Updating the init.rd and kernel (linux) files in the "dapper" 
folder of the usb boot stick will take care of the problem.

(6) After machine reboots, in some cases there may be a blank screen throughout the installation--check for drive activity to make sure the system is not locked.

(7) When the logon screen (GDM) has launched, do not logon with, use a virtual console instead, ctrl+alt+F1; this avoids software conflicts and the large resource overhead involved in invoking the GDM.

(a) login as caladmin

(b) run the cal CW installation script:

sudo /root/cal/cal-setup.sh

(c) the script will prompt regarding use of disk space--type 'yes'

(d) At the 'NSS Switch' prompt select 'ok' to continue.

(8) The script will automatically add the workstation to the CAL domain. in the event that we have to add it manually, follow the following steps:

Logon to a CW and ssh into 'IO' and issue the following commands:

	(a) cal-admin
	    cal-admin --addworkstation
	    'workstation'

	(b) restart the GDM and the Name Service Cache
	    * Note: all startup services in debian are controlled via the init scripts, /etc/init.d:
	   
	    sudo /etc/init.d/gmd restart
	    sudo /etc/init.d/nscd restart

 * Please not that 'IO' is configured with administrative
scripts and utilities, all admin. tasks must be issued through this workstation.

(9) Just before finalizing the installation, you will be prompted for the admin. principle, which should be of the format, 'user/admin'.

(10) The CAL Autoinstaller script will hang during the connection to jupitor.

To establish the connection, connect to 
root@jupiter (ssh -oGSSAPIAuthentication=yes root@astro.columbia.edu)
and run:

 cal-update-fileserver -w 'workstation'

Post-Installation Modifications

(1) To add the Columbia splash screen at startup/shutdown:

(a) sudoedit /boot/grub/menu.lst, search for the "kopt" line and add 'vga=791'

update: sudo update-grub

(b) sudo dpkg-reconfigure linux-image-(use the newest available kernel)

(2) AIPS Configuration
