Specifies the VV name, using up to 31 characters in length. This specifier can be repeated to remove multiple VVs. If this specifier is not used, the pattern specifier must be used. Specifies a glob-style pattern. This specifier can be repeated to remove multiple VVs. If this specifier is not used, the specifier must be used. See "Glob-Style Pattern" (page 12) for more information. RESTRICTIONS • Issuing the removevv command with invalid VV names causes the command to exit without removing any VVs. • Any VVs exported as Virtual Volume Logical Unit Numbers (VLUNs) are not removed and the command stops at that VV. • Any VV that contains snapshots cannot be removed. EXAMPLES The following example removes virtual volume vv0: cli% removevv -f vv0 The following example removes all the expired volumes: cli% removevv -f expired The following example removes the volumes that start with test and are snapshot: cli% removevv -f -snaponly -pat test* The following example removes vv1_snap if it is a snapshot and all its descendents: cli% removevv -f snaponly -cascade vv1_snap 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" (page 506) for additional information. removevv 259
