  • The vFlash cache metric counters such as FlashCacheIOPs, FlashCacheLatency, and FlashCacheThroughput might not be available when CBT is enabled on a virtual disk. Error messages similar to the following are logged in the stats.log file:

    nnnn-nn-nnT06:17:20.200Z [nnnnnnnn error 'Statssvc.vim.PerformanceManager'] CollectVmVdiskStats : Failed to get VFlash Cache stats for vscsi id scsi0:0 for vm 3
    nnnn-nn-nnT06:17:40.189Z [nnnnnnnn error 'Statssvc.vim.PerformanceManager'] GetVirtualDiskVFCStats: Failed to get VFlash Cache stat values for vmdk scsi0:0. Exception VFlash Cache filename not found!

  • When you delete a VDI environment enabled desktop pool, the VMDK files of the other virtual machine from a different desktop pool might get deleted. Multiple virtual machines from different desktop pools might get affected. This happens after you delete the disk, and the parent directory gets deleted due to an error. The directory is perceived as empty, even though it is not. An error message similar to the following might be displayed:

    nnnn-nn-nnT14:08:03.408-07:00 [nnnnn info 'Default' opID=nnnnnnnn] [VpxLRO] -- ERROR task-19533 -- vm-1382 -- vim.ManagedEntity.destroy: vim.fault.FileNotFound:
    --> Result:
    --> (vim.fault.FileNotFound) {
    --> dynamicType = >unset>,
    --> faultCause = (vmodl.MethodFault) null,
    --> file = "[cntr-1] guest1-vm-4-vdm-user-disk-D-nnnnnnnn-nnnn-nnnn-nnnn- nnnnnnnnnnnn.vmdk",
    --> msg = "File [cntr-1] guest1-vm-4-vdm-user-disk-D-nnnnnnnn-nnnn-nnnn-nnnn- nnnnnnnnnnnn.vmdk was not found",
    --> }
    --> Args

  • The IBM BladeCenter HS23 server that boots from a USB device is unable to write the coredump file when the active coredump partition is configured on an USB device. A purple screen displays the dump attempting to initiate but does not complete.
  • Attempts to upgrade ESXi from 5.1 to 5.5 when using the Mellanox Connect X3 driver might fail due to the way in which the VMNICs are enumerated.
  • An ESXi host might show as disconnected in vCenter Server when the hostd process is not responding. This issue might occur when there is a Permanent Device Loss (PDL) and the underlying file system fails to notify pending All Paths Down (APD) events to the Pluggable Storage Architecture (PSA) layer.
  • To debug performance issues related to NFS datastores, DAVG has been added to the esxtop utility.
