The following example removes the volumes that start with test and are snapshot:
The following example removes vv1_snap if it is a snapshot and all its descendents:
NOTES
■ By default, this command deletes any unused LDs that are not also part of a CPG. This is
equivalent to using the
–ld option. The –ld option still exists for backward compatibility.
■ A newly created LD is guaranteed to be clean. Chunklets of LDs that are removed are
cleaned before they are reused. However regions of an LD that were previously used (for
example by another VV) can contain data from its previous use. If these regions of the LD
are mapped to your user space of a VV, that data can be visible to the host to which the VV
is exported.
If this is a concern, remove LDs when the VV is removed and use only newly created LDs for
your user space. Previous data in LDs used for snapshot data space or snapshot admin space
is not visible to you because these spaces are only visible after being written with new data.
■ Verify the removal of VVs by issuing the showvv command. See showvv on page 22.201 for
additional information.
