Hi,
we have an MD3620F, dual controller, which we have updated the firmware to the latest version available in the DELL website.
Details below :
Current configuration
Firmware version: 08.20.24.60
Appware version: 08.20.24.60
Bootware version: 08.20.24.60
NVSRAM version: N26X0-820890-908
Ever since the update, the system has been performing very poorly. wWe noticed that the virtual disks write cache is suspended as seen below:
Read cache: Enabled
Write cache: Enabled (currently suspended)
Write cache without batteries: Disabled
Write cache with mirroring: Enabled (currently suspended)
The system is marking everything as optimal and batteries are o.k
We have reset the controllers one by one and even performed a whole system shutdown. The problem is still there.
If we tick the box to enable Write cache without batteries, the system performs normally.
We also did a mass disable and enable of both read and write cache.
Any help in resolving this would is appreciated as we have run out of ideas.
Thanks in advance
