Ask Andy Haas to install new releases for you!
-------------------------------------------------------
0) HN/e-news announcement of new release pacman package
https://groups.cern.ch/group/hn-atlas-releaseKitAnnounce/default.aspx
------------------------------------------------------------------
1) Before starting a new install, set up the environment variables
RHEL4-32 bit: built on atlas-prod02.slac.stanford.edu
pacman version = 3.26
AFS: /afs/slac/g/atlas/d/ (currently soft linked to /b/)
export PATH=/bin:/usr/bin:/usr/etc:/usr/afsws/bin:/usr/afsws/etc:/usr/bin/X11:.
source /afs/slac/g/atlas/packages/pacman/3.26/setup.sh
RHEL5-32 bit: built on atlas-prod05.slac.stanford.edu
pacman version = 3.29
AFS: /afs/slac/g/atlas/c/
For some reason, it's necessary to unset PYTHONPATH
export PATH=/bin:/usr/bin:/usr/etc:/usr/afsws/bin:/usr/afsws/etc:/usr/bin/X11:.
unset PYTHONPATH
source /afs/slac/g/atlas/packages/pacman/3.29/setup.sh
-----------------------------------------------------
2) Go to the target release partitions, /c/ or /d/.
cd /afs/slac/g/atlas/c # for example for RHEL5-32bit
Makes sure there is enough space with 'fs lq *'.
There are 17 more AFS partitions mounted, in addition to the /c/ partition.
If more space is needed, send a request to unix-admin@slac.stanford.edu
(All examples below will assume installation in /c/)
---------------------------------------------------------------
3) Installing base release: x.x.x
Issue the pacman command found in the HN/e-news announcement, and direct to pacman.log
pacman -allow any-platform trust-all-caches tar-overwrite
-get http://atlas-computing.web.cern.ch/atlas-computing/links/kitsDirectory/projects/cache:AtlasProduction_15_6_5_i686_slc5_gcc43_opt
>> pacman.log &
------------------------------------------------
4) Installing AtlasProduction cache: x.x.x.x
After steps 1-3, setup the release:
. ~/reldirs/15.6.6/cmthome/setup.sh -tag=15.6.6,32
Issue the pacman command found in the HN/e-news announcement, and direct to pacman.log. For example:
pacman -get http://cern.ch/atlas-computing/links/kitsDirectory/Production/cache:AtlasProduction_15_6_5_1_i686_slc5_gcc43_opt
>> pacman.log &
Note1: After the install is finished,
cd /afs/slac/g/atlas/c/AtlasProduction/15.6.5.1/AtlasProductionRunTime/cmt/
and do 'cmt config'.
Note2: If the AtlasProduction package requires a new DBRelease, it has to be downloaded manually.
Check the status of the Production cache in the corresponding web page,
http://atlas-computing.web.cern.ch/atlas-computing/projects/releases/status/15.6.5.1/AtlasProduction/
which usually lists the DBRelease version number.
If it uses a new DBRelease version, scp the tar file over from lxplus.cern.ch and
put it in /c/DBRelease/ and "tar -xf" and move it as the way others are.
DBRelease tar files are stored in
/afs/cern.ch/atlas/www/GROUPS/DATABASE/pacman4/DBRelease/
This script will do all the work:
#
#get_dbrelease_from_cern.sh, by Andy Haas (SLAC)
#Takes one argument: the DBRelease version, i.e. "9.1.2"
#
cd /afs/slac/g/atlas/c/DBRelease
ssh lxplus.cern.ch "~/bin/bbcp -s 64 -P 2 -f /afs/cern.ch/atlas/www/GROUPS/DATABASE/pacman4/DBRelease/DBRelease-${1}.tar.gz noric09.slac.stanford.edu:/afs/slac/g/atlas/c/DBRelease/"
#scp lxplus.cern.ch:/afs/cern.ch/atlas/www/GROUPS/DATABASE/pacman4/DBRelease/DBRelease-${1}.tar.gz .
tar -xzf DBRelease-${1}.tar.gz
mv -i DBRelease/${1} .
rm DBRelease/current
rmdir DBRelease
rm DBRelease-${1}.tar.gz
----------------------------------------------
5) Problems with release install
Check the postings in https://groups.cern.ch/group/hn-atlas-releaseKitProblem/default.aspx
as others might have similar problems.
Ask Peter or Zach.
If all fails, start a new thread in that forum.
-------------------------------------------------------------------
6) When there is an announcement of new AtlasLogin or AtlasSettings
Go to the install area (/c/ in this example) and execute
pacman -update AtlasLogin
pacman -update AtlasSettings
They are supposed to be backward compatible, unless stated otherwise.
----------------------------------------------------------------------------
7) Updating pacman
There are usually ATLAS announcements asking to install a new version.
New version of pacman can be downloaded from BU.
wget http://physics.bu.edu/pacman/sample_cache/tarballs/pacman-latest.tar.gz
tar -xf pacman-latest.tar.gz
Move the pacman package to /afs/slac/g/atlas/packages/pacman/, go into the new
pacman directory and set up.
cd x.xx
source setup.sh
(Please note that any installs in /c/ or /d/ must stay with the pacman version
that was originally used. pacman does not get updated often, but when it does
it might be a good time to build a new install with it switching between
/c/ and /d/.)
