Error description
Spectrum Protect Snapshot for VMware IFINCR "backup vm" may be completed with status failure (RC12) if client fails the virtual machine disk verification check on 2TB+ vmdks. The client's console shows the following errors: ANS9921E Virtual machine disk, <VMNAME> (Hard Disk 1), verification check failed (99662114816/99662168064). If the disk is on an NFS datastore and the disk size was recently changed, the verification failure is expected and a full backup is required. ANS9919E Failed to find the expected control files for <VMNAME>. The problem occurs if the "size on disk" value doesn't match a multiple of 64kb of the sector size declared in the vm control file.
Local fix
The disk check can be disabled, but the check was put into place to detect unrecoverable backups described by Flash (Alert) number 1684022, TSM data mover backups of VMware guests might be unrecoverable: http://www.ibm.com/support/docview.wss?uid=swg21684022 If, after reading the flash and determining its applicability, you decide to temporarily suspend the check so that IFINCR can be the VM can taken, then disable disk size verification by adding the following line in the dsm.opt file: testflag VMVERIFYIFDISK_LIGHT
