Restore problems with the integration of vmware

When performing a restore of virtual machine, vmware integration is started without problem but after trying to write to drive out the following error messages.

[Warning] From: VEPALIB_VMWARE@machine.domain.inc "/1 Datacenter xxx" Time: 31/03/2016 08:05:38 p.m.
Could not write in the disk scsi0:0 (Error: '-1')

  • Hi,

    I assume this is using SAN or HotAdd. 

    Please be aware of the following:

    1. For restore via SAN, all datastore LUNs presented to the Backup host must be online and read/write:

                    diskpart >list disk

                    diskpart >select disk <x>

                    diskpart >attributes disk clear readonly.

                    diskpart >online disk

    2.  Metadata write is not supported for HotAdd and SAN transport.

    When a program calls VixDiskLib_WriteMetadata with HotAdd or SAN transport, the function returns an error saying “The operation is not supported” and supplied metadata never gets written to virtual disk. The workaround is to close the disk from HotAdd or SAN mode, reopen the disk using NBD or NBDSSL mode, then call VixDiskLib_WriteMetadata.

     This statement can be found at:

    https://www.vmware.com/support/developer/vddk/vddk-553-releasenotes.html

    Under "Known Issues and Workarounds"

    Which implies that SAN only environment is not possible.

    The above means that the Backup host in the session: VEPALIB_VMWARE@machine.domain.inc must have access to the ESXi through the port 902 for SAN or HotAdd restore to work.

    Regards
