Hi,

As a single error I wouldn’t worry about it the error correction on the memory did what it is supposed to do. You may want to update the switch firmware. If the error continues it may be a hardware issue.

Hi Josh thanks for your quick response.

 

Since our SAN Storage is connected to the Stack a firmware update is a bite complicated.

 

There isnt a way to update and or reboot the switches in the stack separatly? 

 

kind regards

There is not a way to update without rebooting the whole stack. You could just monitor it and see if there are any more errors.

Hi Josh,

 

thanks. Maybe this could be a good point for a change request: Feature to reboot stack memebrs separatly to avoid outage of the connected redundance systems? Could you address this or can i address this to the firmware team?

 

best wishes

Feature requests go through sales since they can determine the cost of adding features.
