Vmskipmaxvirtualdisks

The vmskipmaxvirtualdisks option specifies how the backup operation processes VMware virtual machine disks (VMDKs) that exceed the maximum disk size.

This feature is available only if the client operates as a data mover for IBM Spectrum Protect™ for Virtual Environments: Data Protection for VMware.

Use the vmskipmaxvirtualdisks option with the vmmaxvirtualdisks option to specify how the client processes large VMDKs during a backup operation:

Set the vmskipmaxvirtualdisks option to back up the VMDKs that do not exceed the maximum size (and exclude any VMDKs that exceed the size), or fail the operation.
Set the vmmaxvirtualdisks option to specify the maximum size of the VMDKs to include.

In V7.1.3 and earlier, the vmskipmaxvirtualdisks option was named vmskipmaxvmdks. In V7.1.4 and later, vmskipmaxvirtualdisks is the preferred option name. However, the client still processes backup operations with the vmskipmaxvmdks name.

Supported clients

Linux operating systems This option is valid for 64-bit Linux clients that are configured as data movers that back up VMware virtual machines.

Windows operating systems This option is valid for 64-bit Windows clients that are configured as data movers that back up VMware virtual machines.

Options file

Linux operating systems Set the vmskipmaxvirtualdisks option in the client system options file (dsm.sys). You can also specify this option as a command-line parameter on the backup vm command.

Windows operating systems Set the vmskipmaxvirtualdisks option in the client options file (dsm.opt). You can also specify this option as a command-line parameter on the backup vm command.

Syntax

Parameters

No: Specifies that backup operations fail if a VMware virtual machine has one or more VMDKs that are larger than the maximum size. This setting is the default value.
Yes: Specifies that backup operations include VMware VMDKs that are the maximum size (or smaller) and exclude any VMDKs that are larger than the maximum size.

Examples

Options file:

vmskipmaxvirtualdisks yes

Command line:

Fail a backup operation if a VMDK is larger than 2 TB:

backup vm VM1 -vmskipmaxvirtualdisks=no

Fail a backup operation if a VMDK is larger than 5 TB:

backup vm VM1 -vmskipmaxvirtualdisks=no -vmmaxvirtualdisks=5

Back up VMDKs that are 8 TB or smaller and exclude VMDKs that are larger than 8 TB:

backup vm VM1 -vmskipvirtualdisks=yes -vmmaxvirtualdisks=8
