Cannot add NFS datastore after using VSC, HELP!

[HendersonD]

My host was working fine with this datastore up until today. Today I loaded Netapp's Virtual Storage Console 2.0.1 onto my Virtualcenter server. It creates a tab in the client. On this tab it shows all the Netapp datastores and the hosts. It also shows if the host and datastores are configured properly and if all settings are optimal. Several settings, mostly NFS settings, were not optimal so it set them to the desire values. After doing this I lost access to the NFS export. After working on this for several hours, I need help. Below is the vmkernel log files that show the error. Any suggestions?

I'm not sure the two events are directly related, but I suggest you open a ticket with NetApp Global Support since the VSC installation was the last change to your environment.  Please feel free to send me a private message with the case number.

Eric,

Thanks for the quick response. You were correct, VSC had nothing to do with it. After 6 hours, a complete rebuild of the host, updating of all the firmware on the host, I finally have it solved. I did two different things in the end and then I could add storage. I am not sure which one did the trick:

- I turned off and then back on flow control on the ESX host

- I change the nic order for my storage vSwitch. It has two nics, both active, and I change the order they appear

If you are in IT long enough there are always a few long nights, this was one of them. It is 1:30am and I am heading home.

Thanks for the update.  I'm sorry to hear about your long night.  You're right about IT... I've been there and done that as well.  😉
