PowerStore: User unable to move or create a new NAS Server in PowerStore Manager
摘要: "Move that particular NAS Server" and "Create NAS Server" buttons are unavailable in PowerStore Manager as a result of uncleared alerts after SDNAS-Docker panic or SDNAS HA event.
症状
After a panic in SDNAS, the nas_server_down alerts may not get cleared for a couple of hours. The "Move NAS Server" option is grayed out in the PowerStore Manager until the clear event is processed.
原因
SDNAS panic generates multiple SDNAS-events. Due to this sudden increase of SDNAS-events, especially during a panic scenario, CP Event Framework is not able to process the events immediately.
The events are getting queued up, which may cause a delay in the CP Event Framework process.
As there are many REST-API requests, regarding local_appliance_information, from the adapter to check whether CP is up or not for modifying operations of objects, this continuous request from the adapter slows down the event-loop thread.
As a result, "Move that particular NAS Server" and "Create NAS Server" buttons are disabled from the PowerStore Manager.
解决方案
This is an auto-resolved issue which is resolved within a few hours.
In the meantime, user can use the Rest API to move NAS-Server.
