Release Notes

ESXi may fail to install or boot on a NUMA-enabled
system
Description: On a Non-Uniform Memory Access (NUMA) enabled system, ESXi may fail to install
or boot because of unbalanced memory distribution across the nodes. The
performance of the system may be degraded. The following error message is
displayed: The BIOS reports that NUMA node X has no memory.
This issue is either caused by a poorly configured BIOS or a unbalanced distribution
of memory modules.
NOTE: A NUMA-enabled PowerEdge M905 system installed with ESXi with the
Node Interleaving option disabled in the BIOS may fail to boot. This issue
occurs if the processor nodes are not populated with similar memory size.
Applies to: ESXi 5.0
Solution: VMware recommends populating all the processor nodes with similar amount of
memory to enable balanced distribution of memory across the nodes.
USB optical driver or iDRAC virtual CD drive is not
available to a VM
Description: If a USB optical driver or an iDRAC virtual CD drive is connected to an ESXi host
after the system completes boot, the device may not display from the Host Device
drop-down menu under VM Settings tab in vCenter Server or vSphere Client.
Applies to: ESXi 5.0
Solution: To resolve this issue, complete one of the following tasks:
• Reconnect the ESXi host to vCenter Server or vSphere Client.
• Restart the management agents on the ESXi host.
vCenter server or VI client does not report a failed or
critical array
Description: In the Virtual Center Hardware Health Status page, critical or failed arrays are not
reported for the degraded or failed hard drives.
Applies to: ESXi 5.0
Solution: There is no functionality loss.
