is the default mode. High-speed mode provides faster access speed by using more processors to handle
data access. However, high-speed mode limits the number of available ports to one port on the channel
adapter (CHA) board.
•
Create/Delete LDEVs. Device Manager allows you to create new LDEVs and delete existing LDEVs on
the StorageWorks XP1024/XP128 storage subsystem (see sections
10-4-3
, and
10-4-4
). You can create
standard OPEN-x LDEVs or custom-size Virtual LVI/LUN devices which are smaller than standard LDEVs
(minimum size = 36,000 KB for other than OPEN-V, 48,000 KB for OPEN-V).
•
Configure LUN Expansion (LUSE). Device Manager allows you to configure custom-size LUSE volumes
on the StorageWorks XP1024/XP128 storage subsystem. A LUSE device is a combined LU which can be
from 2 to 36 times larger than a standard OPEN-x LU. LUSE devices are created from unallocated
LDEVs.
You can create a StorageWorks XP1024/XP128 LUSE device that does not have a volume path (see
section
8-6
). You can also create a XP1024/X128 LUSE device when allocating a volume path to an
LDEV (see section
8-4
) or when adding storage to a storage group (see section
7-6-2
).
•
Add/Delete Volume Path. Device Manager allows you to add and delete volume paths (specifying ports,
host storage domains, and LUNs) for the LDEVs on the connected StorageWorks XP1024/XP128 storage
subsystems.
NOTE:
Regarding High Availability: Device Manager allows you to configure multiple paths to volumes
as needed for path failover capability.
For details, refer to the HP StorageWorks LUN Configuration and Security Manager XP User Guide for
the XP1024/XP128.
2-3-3 Configuring the StorageWorks XP512/XP48 Storage Subsystem
Device Manager supports the following configuration functions for the StorageWorks XP512/XP48 storage
subsystem and its volumes:
•
Configure Ports. Device Manager allows you to configure the host mode and fibre topology settings for
the fibre-channel ports on the StorageWorks XP512/XP48 storage subsystem (see section
10-3-1
).
•
Configure Adapters. Device Manager allows you to configure the speed mode for the fibre-channel
adapters on the StorageWorks XP512/XP48 storage subsystem (see section
10-3-4
). Standard mode is
the default mode. High-speed mode provides faster access speed by using more processors to handle
data access. However, high-speed mode limits the number of available ports to half of the ports on the
channel adapter board.
•
Configure LUN and WWN Groups. Device Manager allows you to configure the LUN groups and WWN
groups on the StorageWorks XP512/XP48 storage subsystem, including creating, deleting, and modifying
LUN groups and WWN groups (see sections
10-3-2
and
10-3-3
).
•
Create/Delete LDEVs. Device Manager allows you to create new LDEVs and delete existing LDEVs on
the StorageWorks XP512/XP48 storage subsystem (see sections
10-4-3
and
10-4-4
). You can create
standard OPEN-x LDEVs or custom-size Virtual LVI/LUN devices which are smaller than standard LDEVs
(minimum size is 36 MB).
•
LUN Expansion (LUSE). Device Manager allows you to configure custom-size LUSE volumes on the
StorageWorks XP512/XP48 storage subsystem. A LUSE device is a combined LU which can be from 2 to
36 times larger than a standard OPEN-x LU. LUSE devices are created from unallocated LDEVs.
You can create a StorageWorks XP512/XP48 LUSE device only when allocating a volume path to an
LDEV (see section
8-4
) or when adding storage to a storage group (see section
7-6-2
). You cannot
create an XP512/XP48 LUSE device that does not have a volume path.
•
Add/Delete Volume Path. Device Manager allows you to add and delete volume paths (specifying ports,
and LUNs) for the LDEVs on the connected XP512/XP48 storage subsystems.
NOTE:
Regarding High Availability: Device Manager allows you to configure multiple paths to volumes
as needed for path failover capability.
For details, refer to the HP StorageWorks LUN Configuration and Security Manager XP User Guide for
the XP512/XP48.
2-4 Data Management Operations
Device Manager allows you to perform data management operations such as LUN security and data
replication/backup (using, for example, Continuous Access XP and Business Copy XP) on the storage
subsystems which have been added to Device Manager.
