- Slow virtual machine I/O performance
- I/O starts as expected, but then decreases
- No errors or events are logged in the vmkernel.log file
- The esxtop command reports high DAVG values during the slow performance
To workaround this issue run these commands in either the DCUI or via an SSH session:
esxcli software vib remove -n ilfu
esxcli software vib remove -n LSIProvider
Restart the ESXi 5.0 host.
This issue does not occur with VMware vSphere Hypervisor 5.0 Update 1 IBM Customized image.
