VNX FF_ASSERT_PANIC and how VMs reacted

A couple of nights ago I had the dubious honor of experiencing a FF_ASSERT_PANIC on my VNX5700. Both SP's rebooted at roughly the same time.

This array mostly services VMWare ESX. None of the ESX servers themselves were phased, but there was a vast difference in how Linux VM's reacted vs. how Windows VMs reacted.

Amazingly enough, only ONE Windows VM was affected. The rest weathered the storm unphased.

Conversely, ALL 400+ Linux VMs went into "read only" mode and had to be rebooted. These VMs are almost exclusively RHEL6, with a few other distributions mixed in.

Any insight into why the Windows VMs were fine (unexpected) and the Linux VMs all got stupid (unexpected)?
