Yellowstone, Geyser, and Caldera will be taken down for maintenance on June 18 to apply a firmware update to the central Juniper switch of the management network. We are reserving a full day for this outage, since it may entail a full reboot of the compute nodes. We will let users know when Yellowstone returns to service via a Notifier message.
During the outage, CISL will also apply some patches to LSF 8. These patches address a number of application start-up and performance issues.
The GLADE team has also decided to perform several updates, the most urgent of which is a firmware update for some of the GLADE drives to bring the systems up to date. Because Yellowstone will already be down, GLADE will be taken down from 8 a.m. until 10 a.m. to replace the firmware.
Additional GLADE software upgrades related to the planned upgrade of GPFS will also be carried out during the day. However, these will be handled via a rolling upgrade that does not require downtime.
During the downtime, no services will be able to access GLADE. Web access to the Research Data Archive (RDA) will also not be available.
Web access to RDA data files and submission of subsetting requests, as well as other GLADE services, such as Globus Online, will return to service after the GLADE team completes the firmware update. Processing of RDA subsetting requests will be delayed until after the Yellowstone downtime.
