LCU replacement project: Lookback & Lessons learned

Arno Schoenmakers ILT-TO meeting 6 April 2017, Amsterdam

31

LCU replacement project

Started in May 2016

Oldest LCU in place since 2010

Major overhaul of existing systems:

New hardware, more memory, energy efficient CPU

New OS (CentOS 7.2) and going from 32-bit to 64-bit, no kernel-

PPS dependency anymore

New WinCC 3.14 Scada system

Use of XCAT + Ansible to install/setup all systems

Many systems: LCUs (50), Central systems (4),

Test/build/development systems (8)

Preparations

Systems ordered in June 2016, delivered in July

Preparing & Testing

Central systems test setup using virtual hosts (June/July)

LCU Test setup with Station hardware in Lab (August)

LCU Field setup on CS302 (October); participate in production

observations.

Preparations for NL replacement campaign started in October

Collect manpower (4 teams of 2 persons)

Instructions

Preparation of all LCUs and related equipment

Rollout on Nov. 7th. All systems replaced in one day;

Only 1 system had cables switched, fixed on the spot. All

others systems worked well from the start.

32

Replacing International LCUs

Date set for Dec 6th; no objections from international staff.

Systems installed and prepared for shipment

Many contacts with international station staff to make sure

systems were expected and sent to the right address

Keep track of shipments through Track&Trace

2 systems were in the wrong truck, but that was fixed by

DHL.

All systems arrived safely and in time.

Local staff had been booked and instructions were provided.

33

Replacing international LCUs (2)

On 6 Dec,

First station to report in was DE601

Station not working! We could not see the GPS signal. What

was wrong?

In the mean time, other stations started working as well; it

became a bit hectic in the ASTRON control room….

Other stations had no such issues..?

Turned out that DE601 had a modified setup for the GPS

because receiver had been broken. We sent a new receiver, and

then it worked fine

By the end of the day, all systems had been replaced and

checked for proper functioning.

Problems started when switching to LOCAL mode on Friday….

Do announcements for new LOFAR releases reach all who

should know about it?

Release dates and stop days now in the Wiki

(http://www.lofar.org/operations/doku.php?id=public:important_dates)

Release notes and instructions in Wiki (requires Wiki account)

Local configuration changes: If permanent, please

communicate these to me ([email protected]), so I

can adapt the repository for local install.

34

Issues after replacement

Some of the issues that were reported after the placement:

Slow login from local systems to LCU

Hanging systems after going to LOCAL mode

Missing File/Directory permissions for local user accounts

Observing scripts failing and hanging on FR606/SE607

iStnMonitor not functioning properly

As of now, all these issues have been fixed (afaik…)

Let me know when there are still problems!

35

Lessons learned….

We have had a project evaluation at ASTRON. Main points:

On the positive side:

Very happy with timely, positive response, cooperation and

patience of all ASTRON and station staff.

We had prepared switch for NL stations very well; indeed

we had no major issues there

Overall, project finished well within budget of ILT

All systems have run nearly flawlessly since replacement.

36

Lessons learned [2]….

On the other hand…

We underestimated the additional complexity of international

stations.

Should have used one International station as testbed for

two/three weeks before rolling out all systems

First switch to LOCAL mode should have been planned the

day after the handover (during weekday), so issues could

be found and solved immediately, not in a weekend rush.

Difficult to set up right communication channels from the start.

Not at all stations had been clear what the plans where with

the old LCU (keep in place or remove from station).

37

Open issues and future plans

Sometimes an LCU does not boot properly after a reboot

BIOS issue, currently tested on NL stations with manufacturer.

Future plans:

More frequent updates/patch installs of OS, WinCC

Twice a year during LOFAR stopdays

Other ideas? Do let us know!
