ESXi 6 ML350Gen 9 smart array b140i + lost access to volume

[eng_HK]

Hi all,

I have a Ml350 gen9 with a smart array b140i, bought on april 2015, installed end of april.

After a few months of working with esxi 6.0 (HP custome image) today we are expecting a lot of problem with the virtual machine running of that server.

In the event log of the vsphere client, we using esxi we are very small company, in the log we can see 

 continuosly error like :

Lost access to volume ... due a connectivity issue. Recovery attemp is in progress

after few second or 1 minute depends 

Successfully restored access to volume 

This gave us a lot of problem because the virtual machine seems that are running but their are freezed so no login to the domain is permitted and the other service doesn't works.

Please I need some help!

Thx
