Removing Virtual Volumes
InForm OS Version 2.3.1 3PAR InForm CLI Administrator’s Manual
◆ <VV_size g|G|t|T> is the size of the volume in MB, GB, or TB. If g|G|t|T is not
specified,
VV_size is the number of MBs. For example, 50g specifies 50 GBs.
7.17 Removing Virtual Volumes
 To virtual volumes, issue the removevv <VV_name> or removevv <pattern> command,
where:
◆ <VV_name> is the name(s) of the virtual volume(s) to be removed.
◆ <pattern> is the name of the pattern according to which virtual volumes are to be
removed.
For a complete list of options available for the
removevv command, see the InForm OS
Command Line Interface Reference and InForm CLI Help.
7.18 Exporting Virtual Volumes
Virtual volumes are the only logical storage component visible to hosts. A virtual volume can
be exported, or made accessible, to one or more hosts. The host sees the exported volume as a
LUN connected to one or more ports. Once the virtual volume is exported to a host, the host
can send requests to the LUN.
A volume-LUN, or VLUN, is a pairing between a virtual volume and a logical unit number
(LUN), expressed as either a VLUN template or an active VLUN. For information about VLUNs,
refer to the InForm OS Concepts Guide.
7.18.1 Creating VLUN Templates
A VLUN template creates an association between a virtual volume and a LUN-host, LUN-port,
or LUN-host-port combination by establishing the export rule, or the manner in which the
volume is exported. A VLUN template enables the export of a virtual volume as a VLUN to a
host or hosts. Those volume exports, which are seen as LUNs by the host or hosts, are active
VLUNs.
A VLUN template can be one of the following types:
■ Host sees - allows only a specific host to see a volume.
■ Host set - allows any host that is a member of the host set to see a volume.
