Command line interface

5.4.13.4. sr-introduce

sr-introduce name-label=name physical-size=physical size type=type content-type=content-

type uuid=SR UUID

Just places an SR record into the database. The device-config parameters are specified by de-

vice-config:parameter_key=parameter_value (for example, device-config:device=/dev/sdb1).

Note

This command is never used in normal operation. It is an advanced operation which might be useful

if an SR needs to be reconfigured as shared after the fact, or to help recover from various failure

scenarios.

5.4.13.5. sr-probe

sr-probe type=type [host-uuid=UUID of host ] [device-config:config_name=value ]

Performs a backend-specific scan, using the provided [device-config] keys. If the [device-config] is complete

for the SR backend, then this will return a list of the SRs present on the device, if any. If the [device-con-

fig] parameters are only partial, then a backend-specific scan will be performed, returning results that will

guide the user in improving the remaining [device-config] parameters. The scan results are returned as

backend-specific XML, printed out by the CLI.

The exact [device-config] parameters differ depending on the device type. See Chapter 3, Storage for

details of these parameters across the different storage backends.

5.4.13.6. sr-scan

sr-scan uuid=SR UUID

Force an SR scan, syncing the xapi database with VDIs present in the underlying storage substrate.

5.4.14. Task commands

Commands for working with long-running asynchronous tasks. These are tasks such as starting, stopping,

and suspending a Virtual Machine, which are typically made up of a set of other atomic subtasks that together

accomplish the requested operation.

The task objects can be listed with the standard object listing command (xe task-list), and the parameters

manipulated with the standard parameter commands. See Section 5.3.2, “Low-level param commands” for

details.

Task parameters

Tasks have the following parameters:

Parameter Name Description Type

uuid The unique identifier/object reference for

the Task

read only

name-label The name of the Task read only
