We have successfully reinstalled the login node for Edda, you can now access edda.vpac.org and queue jobs.
We are reinstalling compute nodes now, once we are happy with the state of them we will start jobs running on them!
Thank you for your patience on this.
This morning we had the old UPS removed that was disconnected as part of the power work over the weekend.
We have also taken delivery of the new UPS and Chloride Hydride are currently installing the new batteries and will be commissioning the unit tomorrow.
The machine room was also prepared for the extra air-conditioning unit that is due to arrive in early September with the removal of a large data safe that was located in the machine room.
We are now able to talk to the hardware management device from the cluster management system.
We are now able to finish off updating the nodes firmware and migrating them to using the new authentication system and storage.
Sadly Edda is still down due to an incompatibility between the firmware on the management device and the cluster management software. We are downloading the previous version of the firmware for the management device and will downgrade to that version tomorrow morning. We hope that this will let us power up the Edda nodes again.
Apologies for the inconvenience!
Wexstan is now back online - we are working on some internal issues with Edda at the moment.
After the weekend power down we are working on bringing back Edda and Wexstan but need to complete the following additional work first:
More news as we have it.
Brecca was shutdown for the final time today, and in the near future will be moved to Monash to be reincarnated as a VPAC cluster that will be accessed purely via the grid by VPAC members.
Here are the final moments of Brecca in its current incarnation. David Bannon issues the final shutdown command on the management node.
The shutdown in progress.
Next week Brecca will be moved out of the way in the VPAC machine room and the first two racks of the new cluster, Tango, will be set into its place. The final rack will join Tango once the new air conditioning unit has been installed to the rear of Tango.
It’s been a week since the last update, and the reason for that is that we’ve been flat out here! All three of the racks now have all the delivered nodes racked up..
..and last weekend the cablers were in wiring up the racks with made to measure tested cables making a rather nice looking arrangement.
This next weekend we have a total shutdown in the machine room so that the electricians can upgrade the wiring ready for our new UPS to arrive on Tuesday and also prepare for the additional air conditioning unit which is due in early September.
Today the last rack arrived and stands ominously in the corridor, waiting for its imminent move into the machine room.
The racking of the compute nodes proceeds apace - Xenon have one rack almost full and another started.
Today we had another 29 compute nodes arrive..
..stacked and ready to rack!
