Concerne/Subject: Implementation of RISC decommissioning

___________________________________________

The following sections describe the proposed practical steps which will be taken to implement the decommissioning plan for RISC systems presented by Manuel to FOCUS on 2nd March 2000. In addition the last section describes IT/PDP UNIX support team’s interpretation of what it means to freeze an operating system, which feature in the decommissioning plans.

AIX Decommissioning

The phase out of AIX was presented to FOCUS by Manuel in two steps:

2000-12-31

End of physics on RSPLUS

2001-12-31

Shutdown RSPLUS

This will be practically implemented by the following timetable of steps:

2000-10-16

Notification of plan on RSPLUS motd, Xbanner and cern.computing

2000-11-01

CNL article

2000-11-30

Release the final version of SUE for AIX

2000-12-01

Prepare LXPLUS by adding 10 nodes and LXBATCH by adding 10 nodes

2000-12-18

Remove RSPLUS from list of services presented in the menus of Xterminals, HEPiX X11 sessions and NICE

Create a separate registration group RSPLUS distinct from PLUS and delete from the RSPLUS passwd file the accounts in the physics groups, for example: XU, XV, XX,WS, ZH, ZP, Z2, Z5.

2000-12-19

Shutdown RSBATCH and reboot RSPLUS

2001-01-04

Add 2 extra nodes to CHORUS_WGS (Check with Helge)

2001-03-01

Move fatmen and hepdb functionality to a SUN machine and shutdown shd15

2001-07-01

Freeze OS for AIX: Last release of ASIS for AIX

2001-07-02

Notification of plan on CHORUS_WGS motd and cern.computing

2001-12-19

Shutdown RSPLUS and CHORUS_WGS

Shutdown AIX installation servers, and ASIS reference machines

Remove AIX documentation and web pages

Remove AIX problem reporting domain in Remedy

HP-UX Decommissioning

The phase out of HP-UX was presented to FOCUS by Manuel in three steps:

2000-12-31

Restrict HPPLUS and CSF to LEP only

2002-12-31

Shutdown CSF

2003-12-31

This will be practically implemented by the following timetable of steps:

2000-10-16

Notification of plan on HPPLUS motd, Xbanner and cern.computing

2000-11-01

CNL article

2000-12-18

Delete LSF queues to non-LEP clusters

Create a separate registration group HPPLUS containing accounts in groups XU, XV, XX, WS extracted from the PLUS passwd file

2001-12-19

Shutdown ATLAS HPs (atlas01-10, atlasb01-b10)

200?-??-??

DUX Decommissioning

The phase out of DUX was presented to FOCUS by Manuel in two steps:

2000-12-31

Restrict DXPLUS to LEP only

2003-12-31

Shutdown DXPLUS and SHIFTALEPH and SHIFTDELPHI DUX machines

This will be practically implemented by the following timetable of steps:

SGI Decommissioning

The phase out of SGI was presented to FOCUS by Manuel in one step:

2003-12-31

Shutdown LEP SGIs

This will be practically implemented by the following timetable of steps:

2000-11-01

CNL article

2002-07-02

Ideas on freezing an Operating System

Frozen OS software

No more system patches

No more vendor patch or upgrade for applications (compilers, X, etc...)

System support based on minimal effort

Frozen SUE

No more security patch

No more configuration changes (network, AFS, kerberos, sendmail, etc…)

Frozen ASIS

A platform is declared frozen in ASIS when all applications existing in the repository are retained but no new package or version of a package is ever introduced in the repository for this architecture. The reference machine which corresponds to this platform is shutdown. The recommended setup becomes to have all products locally installed and to remove ASISwsm from the crontab.
