VDDK 5.0 does not return error for SAN write to offline LUN (2010428)
For backup and restore software running through a proxy, this issue causes backups and restores to return success, when nothing is actually read from or written to virtual disk.
A fix was identified and is provided in the VDDK 5.1 and VDDK 5.0 U2 releases.
For earlier releases, the workaround is to always make sure the LUN is online and in read/write mode before attempting a restore. After a proxy restore, you can return the LUN to read-only mode in the proxy.
