Solaris Installation Procedure

This sections describes Solaris 10 installation procedure for CLON cluster (Sparc-, Xeon- and Opteron-based machines).

You will need 5 CDs 'Solaris 10 Software' (or one DVD) and one DVD 'Software Companion'. Download CDs or DVD image from http://www.sun.com. If you do not have DVD-ROM, you can mount iso image of the Companion after system itself is installed.

Boot from CD1. Several questions will be asked, for example for clonxt2:

 hostname: clonxt2
 IP address: 129.57.167.108
 mask: 255.255.255.0 (will be written to /etc/netmasks)
 route: 129.57.167.99 (others: 129.57.68.100, 129.57.69.1, 129.57.160.1, will be written to /etc/defaultrouter)
 services: choose DNS
 domain name: jlab.org
 DNS servers: 129.57.167.5, 129.57.167.14, 129.57.32.100
 search domain: jlab.org, acc.jlab.org (will be written to /etc/resolv.conf)

Partition disk: if only one disk exist, set 12GB for 'swap', 40GB for system '/', mount the the rest as '/space' (clon05 and others with smaller disks: 4096MB swap, 15GB /). If 2 disks exists and there is no intension to use second one, make it /space and use whole first disk for / and 12G swap. Sun has its own disk name scheme, for example c1t0d0 means ... .

NOTE: 'format' command shows all disks.

Follow instructions on screen and finish installation.

Install software from CD 'Software Companion'. Use it's README and follow instructions. If you want to mount iso image use loopback file driver lofi, for example:

 lofiadm -a /root/sol-10-u3-companion-ga.iso /dev/lofi/1
 mount -F hsfs -o ro /dev/lofi/1 /mnt

Image will be mounted as /mnt. To unmount do following:

 umount /mnt
 lofiadm -d /dev/lofi/1

After installation is finished do following (use /opt/sfw/bin/emacs to edit files):

 /etc/default/login: comment out CONSOLE=/dev/console
 /etc/ssh/sshd_config: PermitRootLogin?: 'no' - change to 'yes'
 svcadm restart /network/ssh (to show all services, type 'svcs')

From now on 'ssh root@clonxt2' is possible from remote host.

 create /etc/defaultdomain with one line containing 'CCCHP'
 add to /etc/hosts all hosts to be used in 'ypinit -c' command (see below)
 execute 'domainname CCCHP' (or reboot)
 ypinit -c
 next host to add: clon00
 clon10
 ccs10 (for EEL building put it on first place)
 svcadm enable /network/nis/client (or start, or restart ???)
 ypwhich - shows NIS server (must show first one in the list above)
 ypcat passwd | grep <username> - shows id/gid etc information

Edit '/etc/nsswitch.conf':

   hosts: files dns ('dns' for clon00 and clon10 only ???)
   passwd: compat
   group: files nis
   netgroup: nis
   automount: files nis

Fix accounts (can be used to add new account !):

 /etc/passwd: fix root, add clasrun (for clon00/clon10 add also clasboot, clascron, clasmail), add last 3 lines
 /etc/shadow: add clasrun, etc, add last line
 mkdir /root (or 'ln' to file server; normally we have it locally); copy .cshrc file from another machine's /root directory,
 it must looks like following:

   #
   # .cshrc for root on clon cluster solaris machines
   #
   setenv PATH ${PATH}:/opt/SUNWspro/bin
   setenv PATH ${PATH}:/opt/sfw/bin
   setenv PATH ${PATH}:/usr/sfw/bin

   setenv LD_LIBRARY_PATH /opt/sfw/lib:$LD_LIBRARY_PATH
   setenv LD_LIBRARY_PATH /usr/sfw/lib:$LD_LIBRARY_PATH
   setenv LD_LIBRARY_PATH /opt/local/lib:$LD_LIBRARY_PATH
   #
   set prompt="%m:%C> "
   #
   alias ll "ls -al"
   #
   #temporary!!!
   setenv CODA /usr/local/clas/release/current/coda
   #

Automount:

   /-      /etc/auto_direct
   /-      auto_direct.ep
   /u      auto.u.ep
   /w      auto.w.ep

Restart automount service:

 svcadm restart /system/filesystem/autofs

NOTE (to force new hardware recognition ?):

 /kernel/drv/fp.conf
        ..... = "yes"; (see comments in file)
 touch /reconfigure

Reboot machine:

 reboot, or 'shutdown -g0 -i6 -y', or 'init 6' (to power down use 'init 5')
 reboot -- -r (after new hardware installation: '-r' force reconfigure, '-s' force single user mode; 'exit' from single user will continue to multiuser mode)

Install recent patches, SunStudio (without patches !), mysql (client only).

Add new groups (onliners etc): /etc/group contails group name, group id and list of group members, while /etc/passwd contains <group id ??? NO !!!>

Multiple ethernet ports setting: clon machines can be connected to the several subnets; for example clonxt2:

129.57.167.108 - clonxt2 (iprb0) - goto /etc/hosts
129.57.68.23 - clonxt2-daq1 (e1000g0) - goto /etc/hosts
129.57.69.201 - clonxt2-daq2 (e1000g1) - goto /etc/hosts

To configure do following:

1. Add all interfaces to the /etc/hosts file

2. Create /etc/hostname.e1000g0 file containing clonxt2-daq1, etc for every extra port

3. Edit file /etc/netmasks adding new line for every new port, for example:

 129.57.68.0    255.255.255.0

4. Reboot machine, or run command:

 ifconfig e1000g0 129.57.68.23 netmask 255.255.255.0 up
