Hey,
We are having some issues with a virtual environment.
Atleast once a day we get error msgs on our virutal servers and on our LUNs in vCenter.
Info msg in vCenter is:
Datastore LUNX increased in capacity from 0 bytes to xxxxxxxxx bytes 13:34
And it does this as I said one or more times per day. At the same time on our virtual machines that are connected to that server we get:
Log Name: System
Source: LSI_SCSI
Date: 2010-10-27 13:33:33
Event ID: 129
Task Category: None
Level: Warning
Keywords: Classic
User: N/A
Computer: serverX
Description:
Reset to device, \Device\RaidPort0, was issued.
Event Xml:
We also get LSI_SAS on newer servers with newer Controllers.
The problem is that it hangs the server for a few short seconds, and this makes all applications that have connections to databases break and they need to be restarted.. our customers doesn like this at all as you can imagine.
We have two QNap RP-809U NAS servers using NFS towards Vmware vSphere4 and each server has two LUNs and this happends on both LUNs at the same time, so it seems to have something to do with the NAS. I guess the connection goes down for a few second for some reason and then reconnects.
Has anyone been had this problem before and have any suggestions? Its at random times:
