Web Server and Central UNIX Interruption starting Tuesday, March 25

All services on Central UNIX (AIX/HP) will be interrupted
starting on Tuesday, March 25 at 6 p.m., and lasting until
Saturday morning, March 29 at 8 a.m., to accommodate the
migration of user filesystems from the older AIX machines to
the new HP fileserver.  There should be no lost mail during
this interruption.

Modem Service is not affected by this outage.  However,
modem users may not change their passwords until the outage
is over.

NOTE:  This is in addition to any other scheduled downtimes.

All users who use Central UNIX services will be affected.
Users will not be able to log into their accounts during
this time period.  Users of POPmail (Netscape and Eudora)
can neither send nor receive mail from the start time until
8 a.m. on Friday, March 28.

The campus Web server will be unavailable from the start of
the downtime until 12 noon on Thursday, March 27.  User Web
pages will be unavailable until Friday, March 28, at 8 a.m..

For more detailed information on the reasons for the outage
and its long-term benefits and reasons, see the Cal Poly AIX
to HP-UX migration web pages at
http://www.calpoly.edu/~ias/hp-unix-system/.

During this downtime several important migration tasks will
be performed.  First, user files will be archived, then
migrated to the new HP fileserver.  Second, OpenMail and
OpenTime will be migrated to the production mail server.
And finally, all system filesystems will be archived.

Office Vision users sending mail to the UNIX system during
this time may receive a warning message that the mail to the
UNIX system is delayed, but the mail will eventually be
delivered.

As a result of the user filesystems migration, users should
see better performance on the AIX machines.  This is due to
the removal of the fileserver function from the  AIX
machines.  Access to their own files will be slightly slower
than before since all files will be accessed from the HP
fileserver.
