Sr-destroy, Sr-forget, Sr-introduce, Sr-probe

The exact device-configparameters differ depending on the device type. See Storage for details of these parameters across the different storage backends.

sr-destroy

sr-destroy uuid=<sr_uuid>

Destroys the specified SR on the XenServer host.

sr-enable-database-replication

sr-enable-database-replication uuid=<sr_uuid>

Enables xapi database replication to the specified (shared) SR. For example:

xe sr-enable-database-replication uuid=<sr-uuid>

sr-disable-database-replication

sr-disable-database-replication uuid=<sr_uuid>

Disables xapi database replication to the specified SR. For example:

xe sr-enable-database-replication uuid=<sr-uuid>

sr-forget

sr-forget uuid=<sr_uuid>

The xapi agent forgets about a specified SR on the XenServer host, meaning that the SR is detached and you cannot access VDIs on it, but it remains intact on the source media (the data is not lost).

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-configparameters are specified by device- config:<parameter_key>=<parameter_value>, for example:

xe sr-introduce 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 it was created, or to help recover from various failure scenarios.

sr-probe

sr-probetype=<type> [host-uuid=<uuid_of_host>] [device-config:<config_name>=<value>]

Performs a backend-specific scan, using the provided device-configkeys. If the device-configis complete for the SR backend, then this will return a list of the SRs present on the device, if any. If the device- config parameters are only partial, then a backend-specific scan will be performed, returning results that will guide you in improving the remaining device-configparameters. The scan results are returned as backend- specific XML, printed out on the CLI.
