LoadService is called soon after its interface was released by a previous iteration, the call might fail. HotAdd limitation when VMFS block sizes are mismatched HotAdd cannot be used if the VMFS block size of the datastore containing the virtual machine folder for the target virtual machine does not match the VMFS block size of the datastore containing the proxy virtual machine. The HotAdd code now deals correctly with a connection sequence issue. Those customers must use alternate transport modes. To avoid this issue, you could clear the cache between backups, for example with the following command if the Linux kernel supports it: Only 64 bit operating systems are supported with VDDK 5. In the Inventory left-hand panel, select the host.

You might want to modify your backup code to throw an error in such a case.
After restore, the virtual disk could be corrupted. If it works fine in v5 probably it is issue with VDDK version. Check here to start a new keyword search. In v6 we are using VDDK 5. When restoring lazy-zeroed thick disk using SAN transport, if the restore buffer size is larger than the block size of the datastore, writes may fail because the lazy zero flag is not cleared for the second and subsequent blocks.
If you do not do so, you will have for sure performance problems, more than not using jumbo at all, since for every packet there is always a check to see if jumbo can be used, so before using mtu there are some re-transmits. This does not happen with a clean install. By continuing to use our website, you agree with our use of cookies in accordance with our Cookie Policy.
VDDK Release Notes
I am also experiencing performance issues after I upgraded ESX from 4. When a LUN is offline, read and write operations should return an error. What are your bottleneck stats numbers and what backup mode is actually used by your jobs? Thank you for all your support.
This backward compatibility failure is due to changes in the getVM method between vSphere 5. Users browsing this forum: Can now simultaneously mount cloned disks on Windows. The issue was fixed by checking similarity of UUID and getting another if needed.

None of the above, continue with my search. Please try again later or use one of the other support options on this page. HotAdd restore by Windows proxy when opening multiple disks.

VDDK 1.2.1 Release Notes
Multiple calls indicate a problem in program logic. When connecting through vCenter Server 5. KB discusses a similar issue.
For information on VDDK including general information about the development kit, how to obtain and install the software, redistributing it, and issues that were identified or resolved in previous releases, see the VDDK 1.
The problem was fixed in the VDDK 1. Password no longer error-logged gddk clear text When an VDDK error occurred, such as failure to connect or open a disk, the error was logged along with the user name and password in cleartext.
HotAdd limitation when VMFS block sizes are mismatched HotAdd cannot be used if the VMFS block size of the datastore containing the virtual machine folder for the target virtual machine does not match the VMFS block size of the datastore containing the proxy virtual machine. Check frequently for additions and updates to these release notes. The code now cleans up HotAdd files left behind after a crash, such as virtual machines with a previous snapshot, or files belonging to a snapshot that no longer exists.
Because the vixDiskLibPlugin must unload vmacore. If it does not, the workaround is to power cycle the virtual machine. This was true of VCB, but as of vSphere 4. Backup fails if a VM is relocated when a backup is in progress. My experience if you do not use Jumbo frames from 12.1 to the end you will have performance problems bddk its always a good idea to make sure all hardware is updated to the latest firmware.
