TROUBLE AND MAINTENANCE INFORMATION

It is reported that Exceed onDemand does not work after upgrading macOS to Catalina(10.15).
Please be careful if you are using macOS.

We plan to perform hardware maintenance of Cloud Storage (Nextcloud) on the following schedule.

* December 26th (Thursday), 13:00-16:00, 2019.

During this period, there is no suspension of the service, however, access to the cloud storage may be interrupted several times.

There is no impact on services other than Nextcloud such as supercomputer systems and cloud servers.

We apologize for any inconvenience, but thank you for your understanding.

The maintenance has been finished.

The Campus SSO system was replaced on 6th December 2019, but it revealed that users using ELMS-ID cannot log in to IIC user management portal after that.

FOR PERSON WHO WILL APPLY NEW REGISTRATION
We are sorry but the online registration is not available for people using ELMS-ID until early March 2020. Until that time if the ELMS-ID users would like to apply new registration, they should download a PDF form on the portal, then fill out and send it to the User Reception Desk by postal mail.

FOR EXISTING USERS WHO ARE USING ELMS-ID
We began to send the existing applicable users their temporary login IDs, so please use it in order to log in to IIC user management portal.

We deeply apologize for inconvenience.

The following periodic maintenance for the login nodes of Supercomputer system and Application servers are scheduled.
During the maintenance, there will be a possibility that connection to these servers will be failed and that a connected session will be broken.
Batch jobs that will be queued or running on Supercomputer will not be affected by the maintenance.

– Schedule: 9:00 – 12:00, Jun. 17, Aug. 19, Oct. 21, Dec. 16, 2019, Feb. 17, 2020.

Due to the trouble in the SSO system, uses who belong to Hokkaido University cannot access User Portal from outside of Hokkaido University.
We apologize for your inconvenience.

An emergent maintenance for Nextcloud storage will be conducted on the following schedule due to fix vulnerabilities.

* December 4th (Wednesday), 13:00 ~ 15:00, 2019.

Please note that you cannot access Nextcloud during this period.

There is no impact on services other than Nextcloud such as supercomputer systems and cloud servers.

We deeply apologize for your inconvenience and appreciate your understanding.

* The maintenace has been finished.

An emergent maintenance will be conducted in the following schedule:
November 12th (Tuesday), 9:00 – 12:00, 2019.

During the maintenance, Supercomputer system including the login nodes and Application server will stop; users cannot log on them.
If it is predicted that a submitted job will not be completed by 11/12 9AM, the job will be queued (not start) and start after the maintenance; if you will set an appropriate elapsed time in your job script, the job will possibly run before the maintenance.

We deeply apologize for your inconvenience and appreciate your understanding.

* The maintenace has been finished.

An issue on the internal network in Supercomputer system was reported.
We are dealing with this issue, however it has not been completed yet.
We apologize for your inconvenience.

December 9th Follow-up report:
The maintenance has finished, and the status is under monitoring. If you will face the above problems, please let the staff know. Thank you for your understanding.

A network fault occurred between the storage system and the computing subsystem due to a setting error associated with the installation of another system, and the job being executed at that time terminated abnormally.
The token of the job that terminated abnormally is being rewound.
Sorry for the inconvenience.
