LD, LDEV
Arbitrated loop physical address.
A volume on the disk array that accepts HP StorageWorks Continuous Access
or HP StorageWorks Business Copy control operations which are then executed
by the array.
Control unit.
Custom volume size. CVS devices (OPEN-x CVS) are custom volumes configured
using array management software to be smaller than normal fixed-size OPEN
system volumes. Synonymous with volume size customization (VSC). OPEN-V is
a CVS-based volume.
The LDEVs associated with each RAID group are assigned an emulation mode
that makes them operate like OPEN system disk drives. The emulation mode
determines the size of an LDEV.
OPEN-3: 2.46 GB
OPEN-8: 7.38 GB
OPEN-9: 7.42 GB
OPEN-E: 13.56 GB
OPEN-K: Not available
OPEN-L: 36 GB
OPEN-M Not available
OPEN-V: User-defined custom size
An operation that reverses replication direction so that the destination becomes
the source and the source becomes the destination. Failovers can be planned or
unplanned and can occur between DR groups, managed sets, fabrics or paths,
and array controllers.
Fibre Channel. A network technology primarily used for storage networks.
Fibre Channel Adapter.
Fibre Channel arbitrated loop.
Fibre Channel protocol.
Host bus adapter.
Each port can be configured for a particular host type. These modes are
represented as two-digit hexadecimal numbers. For example, host mode 08
represents an HP-UX host.
Logical device. An LDEV is created when a RAID group is carved into pieces
according to the selected host emulation mode (that is, OPEN-3, OPEN-8,
OPEN-9). The number of resulting LDEVs depends on the selected emulation
mode. The term LDEV is also known as term volume.
