About the VDDK 1.2.2
The Virtual Disk Development Kit (VDDK) 1.2.2 is a bug-fix update
to VDDK 1.2.1 and adds support for ESX/ESXi 4.1 Update 3 and vCenter Server 4.1 Update 3.
In most respects VDDK 1.2.2 is identical to the VDDK 1.2.1 release.
For information about VDDK 1.2.1, see the
VDDK 1.2.1 Release Notes.
Compatibility Notices for Partners
The VDDK 1.2.2 utilities and redistributable libraries do not support vSphere 5.0.
To support 5.0 releases, customers should install VDDK 5.0.
Recently Resolved Issues
VDDK 1.2.2 resolves the following issue:
- Snapshot consolidation failure when cleaning up after HotAdd backup.
When VMware Data Recovery (or VADP backup software) tried to clean up after HotAdd backup,
snapshot delete failed as the appliance was reconfigured, and an exception was reported.
The problem was caused by premature exit of the vpxa process,
so vpxa did not inform backup code that HotAdd disks should be removed.
Stale HotAdd disks remained, and were not recognized the next time backup software ran.
This caused failure of snapshot delete, resulting in a buildup of redo logs.
The fix is to wait longer for vpxa to report,
and apply heuristics to clean up stale HotAdd disks if they appear.
The VDDK 1.2.2 fix also works with earlier ESX/ESXi versions
and for stale redo logs left by earlier VDDK versions.
Known Issues and Workarounds
Except for the snapshot consolidation fix,
all the known issues in VDDK 1.2.1 still pertain to the VDDK 1.2.2 release.
