How to proceed storage system upgrade when system report false issue

Publication Date:  2016-09-14 Views:  71 Downloads:  2
Issue Description

OceanStor 5300 is required to upgrade from V3R2 to V3R3. 

Before upgrade the system, there’s a major alarm because of the used capacity is more than 80%.The customer deleted some data and make used capacity lower than 80%, and he also removed the alarm.  The alarm never show up again.
During the systen software upgrading, we inspect storage by inspection tool and everything goes well.  But during the upgrade, toolkit upgrade tool showing whether you want to continue the upgrade since system maybe have major issue


We recheck the system, and did not find any alarm in the system. The issue is there’s no “continue” button to move forward.

Alarm Information

No alarm on Device Manager. But the upgrade status is blocked.


Handling Process

There’s a button called detail.  It’s under “status” which is in the middle right of the interface as below:


Click “detail”. The system will ask you whether you accept the “major error” and proceed with the upgrade, or you want to stop the upgrade. If you are pretty sure the system is working well, please click "accept" to proceed with the  upgrade.
In my case, I’m pretty sure the system is working well since I did an inspection before the upgrade. It’s 100% pass.  So I moved forward to do the upgrade and it succeed finally. 

 

 

Root Cause

Inspection tool only check current alarm.But, the upgrade tool need to check if there's alarm as well as history alarm which manually recovered. If there's alarm manually recovered, maybe the faulty isn't really restored. So, we should not allow upgrade progress continue.

Solution

Double confirm if the history alarm which manually recovered is really resolved or whether it may cause upgrade progress failed.

If not, please click "accept" to proceed with the  upgrade. Otherwise, you should pause the upgrade progress and resolved the faulty first, then continue.

Suggestions

1. Please do not manually clear alarm. If the faulty recovered, the system will automatically clear the alarm.
