DataStore IGMM Filesystem at Risk

Agreed - Short Notice; Complete

Overview

Affected services
  • Network Shared Drives
At Risk Time
02:00 PM, 07-Sep-17 — 03:00 PM, 07-Sep-17
Description
One of the storage controllers that make up the IGMM DataStore file system requires a reset to aid in diagnosis / resolution of an issue. The controller will be unavailable for a period of minutes whilst it is powercycled. There is another controller in the unit to allow for redundancy and storage traffic should use this path instead during this short outage. There should be no noticeable degredation of service though there may be a short pause as storage traffic reroutes.
