Following the last update about the storage issues, we provide you with a new update:


Early November the ISSC identified the first delays observed in the storage (J:\drive).

After this, there has been several (smaller) noticable disruptions of service. From the beginning we were in contact with our supplier Dell to search for the solution. Within the ISSC there is a group of employees with various fields of knowledge that came together on a daily basis in order to solve the problem. The last weeks, analysis resulted in a series of actions from Dell in order to improve the storage environment. These took place in the evenings and weekends and were carried out with as little impact as possible to users. The work performed had to do with changes to the software / firmware of the storage components, but also to the network (iSCSI traffic). Today the storage was available again after 10 minutes of disruption.


The disruption of January 26, 2017, showed that recent changes haven’t produced the desired results. The ISSC and the supplier are working on solving this with the highest priority.


The major call with reference number: M1701 3866 will be closed and continue in Problem: P1611 0002.
