The VPP is back up and ready for work.
VPP status update 20/03/2001 5pm

the last reboot.
VPP emergency downtime 16/03/2001 2-4pm
The I/O system of the vpp hung this afternoon. The symptoms were
similar to yesterdays problems except using some equipment similar
to that replaced yesterday. The equipment has now been replaced
and we expect to be up shortly.
Leonard Huxley Room planned power out 14/03/2001 6:30 - 11:00
The Leonard Huxley Machine Room was powered down on Wednesday for work
on the power grid. The downtime was extended until 3pm as some of the
power cables were difficult to move. As a result of the downtime the
vpp has been completely moved to the new power boards and so will not
require a second downtime.
VPP Emergency downtime 16/01/2001 11:40 - 18:00
(3:15pm) The power has been returned to the vpp, however there is now a
hardware fault in the I/O system. Replacement parts have been installed.
15/3The vpp was returned to users at 6pm.
The VPP suffered a hardware memory fault which crashed the system.
VPP Emergency downtime 12/05/2000 13:10 - 22:15
VPP300 suffered a CPU failure at 1:10pm, requiring an immediate
system downtime. The system was returned to service at 10:15pm.

All ANUSF machinery was powered off in compliance with ITS Y2K
VPP downtime 08/11/1999 8 - 2pm
The VPP300 will be down for system maintenance.
VPP emergency downtime 14/09/1999 10:30 - 11:30
The VPP crashed at 10:30am. The main PE CPU stopped
after an IO job tickled a bug in the kernel. The machine was
rebooted and returned to service at 11:30am.
VPP downtime Monday 24/05/1999 8am-2pm
The VPP is down for a software upgrade. This will include a new
revision of the NQS queueing system which will require all pending
jobs to be cleared. The OS will be upgraded, and various Y2K fixes
applied to the compilers. Any code with references to the 'date'
system call should be recompiled.
VPP downtime Tuesday 20/04/1999 6:30-9am
Update The VPP had a hardware failure on Friday evening, and so
was not fixed until noon, Monday. Some additional work was required to
restore the system and so the downtime has been extended.
We will be mailing out when the system is ready for use.
All ANUSF machines will be unavailable for a test of the fire systems
in the Leonard Huxley Bldg.
VPP downtime Monday 22/02/1999 8am-1pm
During this downtime some Y2K patches were applied. A new 18GB disk
for /short0 was installed (although won't be in production use until
a later downtime). Preventative hardware maintenance was also performed
including firmware updates to disk arrays and the PEs. The ATM switch had
a memory upgrade during this downtime as well.
VPP downtime Saturday 03/10/1998 1pm-5:30pm
The VPP had a problem which shutdown the queues. The machine was returned to
service at 5:30pm on Saturday. During the downtime we took the opportunity
to replace the remaining older disk in /vflvol0.
VPP downtime Sunday 13/09/1998 2pm-11pm, Monday 14/09/1998 8am-11am
The VPP will be unavailable on Sunday (13/9) afternoon for disk
reconfiguration, and on Monday morning (14/9) from 8-11am for
system maintenance and network reconfiguration.
VPP downtime Monday 13/07/1998 7:30am-11:30pm
On the Sunday downtime we will be doubling the size of
/vflvol0 to 36GB, also using
faster replacement drives. We will also be installing
UXP/V V10L20 X98061,
F90/VP V10L10 L98061,
and ANALYZER V12L10 L98031.
During the Monday downtime the ATM card will be moved to PE12. This will
enable two PE's to connect directly to the network and allow faster file transfers
to Mass Data Store. This will also require covpp to be reconfigured and rebooted
In addition there will be a new queue for large
failsafe transfers to the Mass Data Store accessed using a new set commands
called "netmv" and "netcp". Further
details of this command will be posted soon, but if you are interest in this
command please contact email@example.com
The VPP will be down for System maintenance on Monday 13/7 from
7:30am-11:30am. During this downtime PE10 will be fixed and brought back into
service. In addition two VPP Fortran compiler patches will be installed.
VPP downtime Monday 01/06/1998 7:30am-6:30pm
The ANU VPP300 was down for system maintenance. In addition to the installation
of a new version of F90/VPP, some disks were re-organised.
VPP downtime Sunday 17/05/1998 9am-9pm
The ANU VPP300 was upgraded to Fujitsu's X98031 standard package. Details
of this can be found in VPP News.
Due to one of the requirements of the upgrade, all queues were cleared after
the reboot. All mounts from store were restored after automounting was removed.
DOWNTIME INFORMATION BEFORE THE ABOVE IS NO LONGER STORED ON-LINE.
