Fibre Channel adapter
A Fibre Channel PCI host bus adapter (HBA)
located in a controller node. The Fibre Channel
adapter connects a controller node to a host or
to a drive chassis.
filtering
In the InForm Management Console, filtering a
table temporarily removes table entries that do
not meet the specified criteria. See also selecting.
G
Gigabit Ethernet adapter
A network adapter located in a controller node.
The Gigabit Ethernet adapter connects a
controller node to a network for the purpose of
transferring data via the network. See also 3PAR
Remote Copy.
grow
To expand a base volume manually by increasing
the user space, snapshot administration space, or
snapshot data space.
growth increment
The unit of storage by which additional logical
disks are created and allocated to a common
provisioning group (CPG). The growth increment
is used to automatically create and allocate space
on demand as additional resources are required
by the volumes that draw from the logical disk
pool. The default growth increment is fixed at 32
GB, but the minimum growth increment varies
according to the number of controller nodes in
the system (from 8 GB for a two-node system to
32 GB for a four-node system). See Table 10-1 on
page 10.4 for details.
growth limit
User-defined threshold that can be set for
common provisioning groups (CPGs) to cap their
potential size. See also growth warning.
growth warning
User-defined threshold that can be set for
common provisioning groups (CPGs) to alert
users when they reach a certain size. See also
growth limit.
H
host
A set of WWNs of the physical ports on a server.
host-sees VLUN template
A VLUN template that allows a particular host
connected to any port to see a virtual volume as
a specified LUN. See also VLUN template.
host definition
The name of the host plus a list of the WWNs
that make up the host. A host can have a host
definition even though it is not physically
connected to a storage server.
host port
See target port.
host-sees VLUN template
A rule that allows a particular host connected to
any port to see a virtual volume as a specified
LUN.
I
IMP (Initiator Mode Prohibited)
This is a system setting. When IMP is enabled, a
port cannot be set to initiator mode. See also
initiator mode.
