Datastores offline after SW reboot

We have had the same issue on 3 differet ESXi clusters connecting to 4 different Starwind servers whereby rebooting the SW server results in the datastores going offline and not connecting after the SW server has come back up. Rescans of the LUNs etc. don't help. The datastores are permanently offline until the ESXi hosts are rebooted.
However, we have the same 3 ESXi clusters connected to Nexenta storage or Solaris storage with Napp-it and as soon as they reboot the datastores reconnect immediately.
It's really messy that a reboot of Starwind whether expected or unplanned requires a reboot of all hosts to get the datastores back online.
What is the cause of this and is there any solution for it?

That was another scenario with esx reboot. I see this is after a starwind reboot.
I guess there is some locking issue. You could look at this kb
http://kb.vmware.com/selfservice/micros ... Id=1004033 it might be the problem.
I know there has been some problems with vaai and san, you could try to turn off vaai to see if it occurs with vaai turned off. What version of esx do you use?

I use ESXi 5.5 everywhere.
I just don't get this issue with any other SAN software so don't think it's a VMware issue.
Also, I doubt that script will help no amount of manul rescanning or trying to remount volumes from the cli will work.

Do you reboot all the SW servers at the same time? Maybe they are just syncing after reboot and you should wait for some time to get the SW devices active again?

The servers are not in a HA set up, they are standalone storage servers as they have about 60TB storage each and cost of running HA is prohibitive.

Since rebooting of ESXi hosts temporarily resolves the problem it seems to be a kind of VMWare mess I believe. Do you have all the critical updates installed?

Hi craggy,
Please provide me with the following:
- type of StarWind image
- type of L1 and L2 cache if enabled
- is it HA or standalone image
- StarWind build number
