Syntax
Get-XenVBD [[-Ref] <XenRef[VBD]>] [-BestEffort] [-SessionOpaqueRef <string>]
[<CommonParameters>]
Get-XenVBD [-Uuid] <guid> [-BestEffort] [-SessionOpaqueRef <string>] [<CommonParameters>]
Description
Retrieves the VBD objects in the pool. With no parameters the cmdlet returns the whole collection; use -Uuid or -Ref to select one.
VBD: A virtual block device.
Parameters
-BestEffort
If set, the cmdlet continues processing further objects instead of throwing a terminating error when an operation fails for one object.
| Attribute | Value |
|---|---|
| Type | SwitchParameter |
| Required | False |
| Position | Named |
| Accepts pipeline input | False |
-Ref
The VBD object to operate on, specified by its opaque reference.
| Attribute | Value |
|---|---|
| Type | XenRef[VBD] |
| Required | False |
| Position | 0 |
| Accepts pipeline input | True (ByPropertyName) |
| Aliases | opaque_ref |
-SessionOpaqueRef
The session object on which to run the cmdlet. This overrides the default session and lets you target a specific open XenServer connection.
| Attribute | Value |
|---|---|
| Type | string |
| Required | False |
| Position | Named |
| Accepts pipeline input | False |
-Uuid
The UUID of the VBD to operate on.
| Attribute | Value |
|---|---|
| Type | guid |

Examples
Example 1: List every VBD
PS> Get-XenVBD
Retrieves every VBD object in the pool. With no parameters the cmdlet fetches the whole collection.
Example 2: List a VM's disks, excluding the CD drive
PS> $vm = Get-XenVM -Name "web-01"
PS> $vm.VBDs |
ForEach-Object { Get-XenVBD -Ref $_ } |
Where-Object { $_.type -eq "Disk" }
A VBD is the attachment between a VM and a virtual disk, and a CD drive is a VBD too, hence the filter on type. The VM record holds references, so each one is resolved with -Ref.
Example 3: Retrieve one VBD by uuid
PS> Get-XenVBD -Uuid 1871ac51-ce6b-efc3-7fd0-28bc65aa39ff
Retrieves a single VBD. -Uuid is the way to be sure of exactly one object.
