in Exadata General (MOSC) 2 commentsAnswered

Team,

We have recently applied Apr 2021 QFSDPE in one of our Exadata frame.

We upgraded cell server from 19.x to 20.1.9.0.0.210416.

Post that, we have started seeing, flash cell utilization was over 90% before patching and now is only 25-30%. When we dig bit deeper, we see below warning messages in the cell alert log.

Is that indicate any problem ? What does it mean exactly ? Any lead on this? Please help.

"Warning: Disk /dev/sdg utilization is high and could be causing I/O starvation in IORM. Check IORM diagnostics to confirm if the I/O utilization of workloads is expected."
