VMNSDg agent optional attributes (continued)
Description
SkipStorageValidation
Defines whether the VMNSDg agent supports the dynamic disk
groups which are configured on external disks.
In case of SCSI controllers, the disks are considered as internal
(non-shared) if the disk port is same as the port of OS disk, otherwise
the disks are considered as external disks. The external disks can
be shared or non-shared. By default, this attribute blocks the disk
groups configured on any external disk (shared or non-shared).
Set this attribute to 1 if you want the VMNSDg agent to support disk
groups configured on external SCSI disks.
Note: Configuring a VMNSDg agent resource for a dynamic disk
group created on shared storage can cause data corruption and the
VMNSDg agent resource can fault after regular intervals. Symantec
recommends that you use the VMDg agent if the disk groups are
created on shared external disks and use the VMNSDg agent if the
disk groups are created on non-shared external disks.
Default value is 0.
Type and Dimension: boolean-scalar

NativeDisks agent
The NativeDisks agent manages the disks created on local (non-shared) and
non-SCSI storage, which can work without reservation.
The agent brings the disks online, monitors them, and takes them offline using
Logical Disk Manager for Windows. The agent makes the disks highly available.
In combination with the VMwareDisks resource, the NativeDisks agent is
responsible for:
■
While bringing the disks online, ensure that the disks newly attached to the
virtual machine are accessible to Windows.
