Update
Work on Summit has concluded successfully. We were not able to perform the Summit storage update due to not having the update procedure from the supplier in time.
Work is continuing on PetaLibrary/archive.

Update
We will also restart the TSM server tomorrow (Aug 7th) to clear many processes that didn't completed as expected after starting the script that reconciles the GPFS Filesystem with the external storage pool.
That will affect PetaLibrary Archive allocations under "/archive". It won't affect the ones under "/pl/active".
That should be performed by 9am tomorrow. It will be informed once it is completed.

Scheduled
Research Computing will perform regularly-scheduled planned maintenance Wednesday, 7 August 2019. August's activities include
- Reboot a Summit interconnect switch - Reboot Summit compute nodes to test interconnect resiliency - [Potentially] Update Summit storage infrastructure
Maintenance is scheduled to take place between 07:00 and 19:00, though service will be restored as soon as all activities have concluded. We are expecting this to be a brief outage for the Summit interconnect reboot and testing; but we have been advised of a critical update for the Summit storage infrastructure. If we have the update procedure and time to prepare before Wednesday we will likely want to update the SFA at this time as well; but we do not have an estimated duration for that operation yet. Otherwise we may need to take an off-cycle outage to perform this update.
During the maintenance period no jobs will run on Summit resources, and access to Summit storage may be interrupted. If we update Summit storage access will likely be disrupted for the duration of the update procedure.
