Purpose
Remove
a backing device and return the storage back to the storage pool.
Description
The
rmbdsp command
removes a backing device from a virtual SCSI server adapter by removing
its associated virtual target device. By default the backing device
is also removed and its storage returned to the storage pool. If
the
-savebd flag is included then the backing device is not
removed. The backing device can be identified by either specifying
the name,
-bd, or the virtual target device,
-vtd.
If the backing device is identified by the name, -bd,
then the storage pool the device is contained within must also be
specified, -sp. If the storage pool is not given the default
storage pool is assumed. Note: - A storage pool must be specified if the given backup device name
is a file backing device. The default storage pool is
not assumed.
- The logical volume specified for the -bd option
cannot be assigned to a shared memory pool (to be used as a paging
space device by a shared memory partition).
If -vtd flag is given only the specified
virtual target device is removed. If -bd flag is given all
virtual target devices associated with the backing device will be
removed.
Flags
| -bd BackingDevice |
Specifies the backing device that is the backing
device. |
| -savebd |
Instructs the command not to remove the backing
device. |
| -sp |
Specifies the storage pool the backing device
is within. |
| -vtd VirtualTargetDevice |
Specifies the virtual target devices that associate
the backing device with the virtual SCSI adapter. |
| -f |
Forces the metadata file associated to the file-backed
disk to be removed. If you also specify the -savebd flag,
the backing device will not be removed. CAUTION: Only
use this flag if the metadata file associated to the file-backed disk
is corrupt.
|
Exit Status
| 25 |
Specified logical volume is not a backing device. |
Examples
To
remove the virtual target device vtscsi4 and not remove the backing
device associated with it, type:
rmbdsp -vtd vtscsi4 -savebd
