PBD Commands | Citrix Systems 6 specification

Parameter Name	Description	Type

name-label	The name of the patch	read only

name-description	The description string of the patch	read only

applied	Whether or not the patch has been applied;	read only
	true or false

size	Whether or not the patch has been applied;	read only
	true or false

patch-apply

patch-applyuuid=<patch_file_uuid>

Apply the specified patch file.

patch-clean

patch-cleanuuid=<patch_file_uuid>

Delete the specified patch file from the XenServer host.

patch-pool-apply

patch-pool-apply uuid=<patch_uuid>

Apply the specified patch to all XenServer hosts in the pool.

patch-precheck

patch-precheckuuid=<patch_uuid> host-uuid=<host_uuid>

Run the prechecks contained within the specified patch on the specified XenServer host.

patch-upload

patch-uploadfile-name=<patch_filename>

Upload a specified patch file to the XenServer host. This prepares a patch to be applied. On success, the UUID of the uploaded patch is printed out. If the patch has previously been uploaded, a PATCH_ALREADY_EXISTS error is returned instead and the patch is not uploaded again.

PBD Commands

Commands for working with PBDs (Physical Block Devices). These are the software objects through which the XenServer host accesses storage repositories (SRs).

The PBD objects can be listed with the standard object listing command (xe pbd-list), and the parameters manipulated with the standard parameter commands. See the section called “Low-level Parameter Commands” for details.

PBD Parameters

PBDs have the following parameters:
