1 LUN Manager for the XP10000/XP12000
You can connect XP arrays to open system and mainframe hosts using Fibre Channel. Use LUN Manager to
configure host groups, logical units (LUs), and Fibre Channel ports.
LU configuration overview
One of the important tasks in logical unit (LU) configuration is to define I/O paths from hosts to LUs. After
the paths are defined, the hosts can send commands and data to the LUs and can receive data from them.
LUN Manager can also configure security policies to protect LUs from unauthorized access.
Fibre Channel environment
In a Fibre Channel environment, you must configure the Fibre Channel ports on the disk array. With LUN
Manager, you can set addresses and speed, and specify topology for Fibre Channel ports.
Supported emulation types
LUN Manager supports the following device emulation types:
• OPEN-3, OPEN-9, OPEN-8 (XP128/XP1024 only), OPEN-E, OPEN-L, and OPEN-V for open systems
• 3390-3A/B/C and 3380-KA/B/C for mainframe systems
LU paths
After hosts and the disk array are physically connected by cables, switches, and so on, use LUN Manager
to establish paths between the hosts and LUs. These paths are called LU paths and they determine which
host can access which LU.
• Up to 256 LU paths can be defined for a host group in a Fibre Channel environment
• Up to 1,024 LU paths can be defined for a Fibre Channel port for the XP10000/XP12000 array
• Up to 256 host groups can be defined for a Fibre Channel port for the XP10000/XP12000 array
• Up to 65,536 host groups can be defined for one disk array (256 x 256)
• Up to 255 hosts can be included in all the host groups for one Fibre Channel port
Configuring LU paths in a Fibre Channel environment
Before defining LU paths, you must classify server hosts by host storage domains. For example, if Linux and
Windows
host type. When this is done, register the host bus adapters for each host type in the appropriate host
storage domain.
Host storage domains
A host storage domain can contain only hosts that are connected to the same port and cannot contain
hosts that are connected to different ports. For example, if two Windows hosts are connected to port 1A
and three Windows hosts are connected to port 1B, you cannot register all five Windows hosts in one host
storage domain. You must register the first two Windows hosts in one host storage domain and the
remaining three Windows hosts in another host storage domain.
After server hosts are classified into host storage domains, you must associate host storage domains to
logical volumes. In Figure 1, the host storage domain hg-lnx is associated with the logical volumes 00:00,
® hosts are connected to the disk array, you must create a separate host storage domain for each
LUN Configuration and Security Manager XP user guide for the XP10000/XP12000 11
00:01, and 00:02. LU paths are defined between the two hosts in the hg-lnx group and the three logical
volumes.

Host Groups
Figure 1 LU paths configuration in a Fibre Channel environment
LUN Manager lets you define paths between a single server host and multiple LUs. In Figure 1, both hosts
in the hg-lnx host storage domain can access the three available LUs.
LUN Manager lets you define paths between multiple server hosts and a single LU. In Figure 1, the LU
identified as CU-LDEV 00:00 is accessible to the two hosts in the hg-lnx host storage domain.
In Figure 1, the LUs associated with the hg-lnx domain are addressed by numbers 0 to 2. The address
number of an LU is referred to as the logical unit number (LUN). When HP StorageWorks Continuous
Access XP and other optional features manipulate LUs, they use LUNs to specify the LUs to be manipulated.
You can add, change, and delete LU paths when the system is operational. For example, if new disks or
server hosts are added to your disk array, you can add new LU paths. If an existing server host is to be
replaced, you can delete the corresponding LU paths before replacing the host. You do not need to restart
the system when you add, change, and delete LU paths.
If a hardware failure (such as a CHA failure) occurs, there is a chance that some LU paths are disabled
and some I/O operations are stopped. To avoid this, the system administrator can define alternate LU
paths. If one LU path fails, the alternate path takes over the host I/O.
In a Fibre Channel environment, up to 1,024 LU paths can be defined for one host storage domain. Up to
1,024 LU paths can be defined for one port.
NOTE: You cannot define an LU path to LUN On Demand volumes or volumes reserved by Auto LUN XP.
• Up to 256 host storage domains can be created for one Fibre Channel port. Up to 57,344 host storage
domains can be created for one disk array. The maximum number of ports per subsystem is 224.
12 LUN Manager for the XP10000/XP12000
• Up to 255 host groups can be created for one Fibre Channel port.
• You cannot define any LU path to journal volumes.
• You cannot define any LU path to pool volumes.
16-Port FC/CA CHIP product
Although there is not a significant performance gain compared to the 8-port FC/CA CHIP product, the
primary advantage of the 16-port FC/CA CHIP product is its increased FC connectivity (or port count).
High-speed mode is currently unavailable on the 16-port FC/CA CHIP product.
Odd/even LUN data path handling through the processor does not exist on the XP10000/XP12000.
There is no odd/even LUN mapping issue associated with this product. Each processor of the 16-port CHIP
product handles the data flow of two ports (eight total processors for 16 total ports = two ports per
processor).
For load balancing, the two ports serviced by a processor should be considered as one port. Although
volumes can be mapped to both ports handled by a processor, the I/O will go through one processor. For
redundancy and performance reasons, consider distributing the load across multiple CHIPs.
When deciding whether to map volumes to ports (LUN mapping) for host connectivity, after considering
load balancing across processors, there is no reason to not use all 16 ports immediately. After considering
load balancing among processors, there is no reason not to use both ports in the I/O path of one
processor or to use both ports in the I/O path of a processor.
Figure 2 16-Port CHIP pair labeling
Port numbering is as follows: Cluster 1 uses CL1-* and CL3-*, while Cluster 2 uses CL2-* and CL4-*,
where * is an alphabetical character designation of the port such as A, B, C, and so on. Ports A, for
example, CL1-A and CL3-A, share the same processor for I/O purposes.
Host groups
Begin by grouping server hosts into host groups. For example, if HP-UX and Windows hosts are connected
to the disk array, you must create a separate host group for each host type. When this is done, register the
hosts in their corresponding host groups. After hosts are classified into host groups, associate the host
groups with LUs.
LUN Configuration and Security Manager XP user guide for the XP10000/XP12000 13
In Figure 3, the host group hpux01 is associated with six LUs. LU paths are defined between the three hosts
in the hpux01 group (WWN_1, WWN_2, WWN_3) and the six logical units LUN00-LUN05.
Figure 3 Host group example 1
Figure 4 Host group example 2
LUN Manager can define paths between a single host and multiple LUs. In Figure 4, each of the three
hosts in the host group hpux01 can access the six LUs. LUN Manager can also define paths between
multiple hosts and a single LU.
Hosts can be members of only one host group for a given port. Host group definitions and members apply
only to the port that they are defined for.
Host modes
As part of registering hosts in host groups, you will be asked for the host mode. Use Table 3 to determine
the host mode.

1. For Windows with any FC HBAs when MSCS is not needed.
2. For Windows with D8602 FC HBAs with or without MSCS.
3. For Windows with Emulex or QLogic FC HBAs with or without MSCS.
4. If you register Windows server hosts in a host group, verify that the host mode of the host group is 0C:
Windows or 2C: Windows Extension. If you are thinking about creating LUSE volumes, such as
expanded LUs, consider setting the host mode 2C: Windows Extension to the host group. If the host
mode is 0C: Windows and an LU path is defined for a volume, you cannot execute LUSE operations
on the volume without unmapping the volume first.
5. When registering Sun Cluster server hosts in the host group (Use this host mode both VERITAS Cluster
Server and Sun Cluster are used).
LUN Security
To protect data from unauthorized access, apply security policies to LUNs. LUN Manager can apply LUN
security to ports to safeguard LUs. If a port has the External attribute, you cannot apply LUN security to the
port.
If LUN security is applied, it limits which host can access which LUs. A host can only access LUs associated
with its host group. Hosts cannot access LUs associated with other host groups.

LUN Configuration and Security Manager XP user guide for the XP10000/XP12000 15
In Figure 5, the hosts in the hpux-G01 group can access LUN0 and LUN1 associated with the same host
group, but cannot access LUN0 and LUN1 in the winG02 host group. The hosts in hpuxG01 can only
access the two LUs, identified by 01:05 and 02:01; the hosts cannot access the LUs 02:00 and 02:02.
Figure 5 Host group example 3 (LUN security)
If LUN security is disabled, the hosts will not be able to access most of the LUs. Hosts will have access to
only those LUs defined in host group 0.
By default, LUN security is disabled on a port, so host group 0 is the only accessible host group reserved
for the port. Initially it contains no LUs or WWNs.
When security is disabled, only LUs defined in host group 0 are accessible to hosts connected to the port,
regardless of any WWNs that may be defined for a host group. After security is enabled, WWNs are
used, permitting or restricting access based on WWN.
If you have more than one host group defined on a port, you can locate host group 0 by disabling LUN
security from the port. When done, the tree display will “gray” out all host groups except host group 0.
RAID Manager command devices
To use RAID Manager commands for Business Copy XP and Continuous Access XP operations, you must
designate at least one LDEV on the disk array as a command device. A command device receives RAID
Manager commands entered from hosts. When you enter a RAID Manager command from a host, the
command is transferred to the target device via the command device.
If you want to restrict access to LUs and by RAID Manager, you can apply command device security in LUN
Manager.
Restrictions
You cannot use the following LDEVs as command devices:
• Volumes that do not have read/write access
• Volumes reserved by Auto LUN
• Continuous Access XP volumes
• BC volumes
• External LUs
• Flex Copy volumes
• Volumes on which VMA is set
• Virtual volumes
16 LUN Manager for the XP10000/XP12000
If you want to use a LUSE volume as a command device, you must specify only the first LU as the command
device.
Fibre Channel port attributes
In Fibre Channel environments, you must configure and set addresses for the Fibre Channel ports. You can
enhance system performance by adjusting the data transfer speed at the Fibre Channel ports and
changing the channel adapter mode.
Fibre Channel topologies
Fibre Channel provides the following topologies:
• Fabric: Uses a fabric switch to connect a large number of devices. Each device has the full bandwidth
of 100 MB/sec.
• FC-AL (Fibre Channel-Arbitrated Loop): A shared-bandwidth topology that can connect up to 126
devices (AL ports).
• Point-to-point: A simple Fibre Channel topology in which two devices are connected directly.
When configuring the disk array, use LUN Manager to specify whether the hosts and the disk array are
connected by a fabric switch. Also, you must specify FC-AL or point-to-point in the LUN Manager pane. The
default is FC-AL.
If you are using a fabric switch, consult the switch’s documentation to learn whether FC-AL or point-to-point
should be used. Some fabric switches require that you specify point-to-point to get the system running.
Arbitrated loop physical addresses
You will need to set addresses for Fibre Channel ports. When addressing Fibre Channel ports, you can use
AL-PA (arbitrated loop physical address) or loop IDs as the addresses (see Table 4).
Table 4 AL-PA and loop IDs

Data transfer speed for Fibre Channel ports
As disk array operation continues, you may notice that a larger amount of data is transferred at some ports
and a smaller amount is transferred at other ports. To improve system performance, set a faster data
transfer speed for ports where a larger amount of data is transferred, and a slower data transfer speed for
ports where a smaller amount of data is transferred.
Standard, high-speed, and high-speed (2 port) modes
The channel adapter boards can operate in standard, high-speed, or high-speed (2-port) mode. Standard
mode is the default. If a channel adapter board satisfies certain conditions, you can set it to high-speed or
high-speed (2 port) mode to improve port performance.
NOTE: High-speed (2 port) mode is available only if firmware version 21.06.22 or later is installed on
the disk array.
High-speed mode can be applied to channel adapter boards that satisfy the following conditions:
• Only one port is planned for use.
• All ports take the same Fibre topology option (on or off).
• All ports take FC-AL as the Connection option.
• All ports use different port addresses and no matching addresses.
• All ports take the same port attribute (Initiator, RCU target, or Target).
If high-speed mode is applied to a channel adapter board, only one of the ports on the channel adapter
board can be used. This port can exclusively use channel processors and fibre optic processors (FOPs) that
would otherwise be reserved for the other ports. Balancing the workload on the processors can improve
system performance.
If high-speed (2 port) mode is applied to a four-port channel adapter board, two ports out of the four ports
cannot be used. The remaining two ports can exclusively use channel processors and FOPs that would
otherwise be reserved for the other two ports.
18 LUN Manager for the XP10000/XP12000
Figure 6 shows an example of High Speed mode applied for one or two port clocks when the channel
adapter board has 8 ports. In case that the channel adapter board has 16 ports, you can also apply High
Speed mode in the same way though there are four port blocks.
Figure 6 Differences between high-speed and high-speed (2 port) modes
If High Speed mode is applied to the four ports in a port block, only two of the ports can be used for
connecting the host. These two ports can exclusively use channel processors and fibre optic processors
(FOPs) that would otherwise be reserved for the other two ports. Therefore, system performance improves.
By balancing workloads on processors, you can expect a greater improvement in system performance.
Before changing the configuration of a port that is being used, perform a backup operation. You cannot
switch between standard and high-speed while you are online to the hosts.

Defining LU paths
To configure a Fibre Channel environment, complete the following major steps:
1. Find the WWNs of the host bus adapters connected to the Fibre Channel ports.
2. Create host groups (”Creating host groups” on page 23).
3. Register hosts in host groups (”Registering hosts in host groups” on page 24).
4. Associate host groups to logical volumes (”Associating host groups to logical volumes” on page 26).
Creating host groups
You can connect multiple server hosts of different platforms to one port of your disk array. When
configuring the system, you must group server hosts connected to the disk array by host groups. For
example, if HP-UX and Windows hosts are connected to a port, create a host group for each host type.
1. Start LUN Manager, and display the LUN Manager pane (Figure 7).
2. In the LU Path tree, locate the port and verify that LUN security is enabled.
NOTE: If the port icon has a key ( ), LUN security is enabled.
If LUN security is not enabled, right-click the port and select Disable->Enable in the shortcut menu.
3. After LUN security is enabled, right-click the port in the LU Path tree and select Add New Host Group.
The Add New Host Group dialog box appears.
Figure 9 Add New Host Group pane
4. In the Group Name box, enter the host group name.
NOTE: It is convenient to name each host group after the host platform. For example, if you are
creating a host group for Windows NT
Host group names are case sensitive and can have up to 32 characters.
5. In the Host Mode list, select a host mode. Host groups on the same port can have different host modes.
6. If necessary, select Option, and select the host mode options. For detailed information about host mode
options, see Table 9 on page 24.
NOTE: After you select Option, the pane expands to display check boxes. The check boxes are
numbered sequentially from left to right. The left-most check box on the upper row is #0, and the
check box immediately to the right is #1, and so on. The numbers indicate option numbers; select
check box #0 to select option #0.
7. Click OK. The host group name and the host mode appear in blue in the LU Path tree.
8. In the LUN Manager main pane, click Apply. A confirmation message appears.
® hosts, the host group name could be WNT or WinNT.

• You want to use TruCluster to set a cluster to the Continuous Access XP P-VOL
and S-VOL, respectively
CAUTION: Do not select options other than those listed in Table 9.
Registering hosts in host groups
Before you can set LU paths, you must register hosts in host groups. For example, if HP-UX and Windows
hosts are connected to a port, you must register them separately in two different host groups.
When registering a host, you can assign a nickname to the host bus adapter. If you assign a nickname,
you will be able to easily identify each host bus adapter in the LUN Manager main pane. Although
WWNs are also used to identify each host bus adapter, a nickname is more helpful because you can
name host bus adapters after the host installation site or the host owners.
When using nicknames, note the following:
• A nickname can consist of up to 32 ASCII characters (letters, numerals, and symbols). You cannot use
the following characters for nicknames:
\ / : , ; * ? " < > | ~
• You cannot use the space character for the first or the last nickname character.
• Nicknames are case sensitive. For example, hp and HP are different nicknames.
To register hosts in a host group:
1. Start LUN Manager, and display the LUN Manager pane (Figure 7).
24 LUN Manager for the XP10000/XP12000
2. In the LU Path tree, locate the port the host group belongs to and verify that LUN security is enabled.
NOTE: If the port icon has a key ( ), LUN security is enabled.
If LUN security is not enabled, right-click the port and select Disable->Enable in the shortcut menu.
3. If the desired host has never been connected via a cable to another port in the disk array, skip to
step 9.
4. In the Port list on the upper right corner of the WWN table (Fibre Channel), select the port to which the
desired host is connected.
5. Select the desired host bus adapter from the WWN table.
6. Select a host group from the tree, and click Add WWN. The Add New WWN (Fibre Channel) dialog
box appears.

Defining alternate paths
LUN Manager can define alternate paths. If an LU path fails, you can switch to its alternate path.
To create an alternate path, copy the original path from one port to another. For example, to define an
alternate for the LU path between the CL1-A port and logical volume 00:01, copy the LU path from the
CL1-A port to another port.
If you want to define alternate paths when LUN security is removed, you must redefine the LU path.

2 Volume Management for the XP10000/XP12000
Use Volume Management to perform the following tasks:
• ”Volume Management (LU Size Expansion)” on page 37)
• ”Volume Size Configuration (VSC)” on page 38)
Volume Management (LU Size Expansion)
Volume Management (LU Size Expansion or LUSE) combines two or more LDEVs to function as a larger
LDEV. As a result, a host can access a greater amount of storage with a smaller number of LDEVs.
Figure 16 shows the effect of a LUSE configuration.
Figure 16 LUSE configuration
LUSE can combine up to 36 LDEVs into a LUSE volume. The LDEV number of the LUSE volume is the first or
lowest number of the LDEVs making up the LUSE volume. This is the top LDEV, and is the number the host
will recognize.
Drawbacks
• Some operating systems may experience slow disk access times with large logical units, if they contain
• The size of a LUSE volume can increase the amount of time required to perform backups.
LUSE rules
• Open volume emulation types OPEN-3, OPEN-8, OPEN-9, OPEN-E, OPEN-L, or OPEN-V are
• The maximum number of LDEVs that can be used to create a LUSE is 36.
• LDEVs must be of the same emulation type.
• LDEVs must be at the same RAID level. Combining RAID 1 and RAID 5 volumes into the same LUSE
• LDEVs or LUSE volumes to be combined must have no assigned path definitions. These are known as

free (or available) LDEVs. For this reason, Business Copy, Continuous Access, TrueCopy (TC390),
ShadowImage (SI390), and Continuous Access XP - Journal pair volumes cannot be targets of LUSE
operations. For more information, see ”LUSE operations that handle a path-defined LDEV” on page 38.
LUN Configuration and Security Manager XP user guide for the XP10000/XP12000 37
• When you combine a LUSE volume with another LUSE volume, the range of LDEVs should not be
overlapped.
For example, if you combine LDEV00, LDEV03 and LDEV05 into LUSE 1, LDEV02 and LDEV04 into
LUSE 2, and LDEV06 and LDEV07 into LUSE 3, you can also combine LUSE 1 and LUSE 3. However,
you cannot combine LUSE 1 and LUSE 2, because the LDEV range in LUSE 1 and LUSE 2 is overlapped.
• A maximum of 256 expanded logical units (LUs) can be configured on the same port.
• The maximum capacity of a LUSE volume is 60 TB for the XP10000/XP12000.
• The access attribute must be set to read/write when creating or releasing a LUSE volume.
• When releasing a LUSE volume, the volume should have no path definitions.
• Combining internal, external, and virtual volumes (V-VOLs) is not supported.
• The IO suppression mode and cache mode settings of the LDEVs combined into a LUSE volume must be
the same.
• All the LDEVs combined into a LUSE volume must be of the same drive type (either the SATA drive or
non-SATA drive).
• VMAs (volume management areas) are not set to LDEVs. For more information about VMAs, see the
HP StorageWorks LUN Security XP Extension User Guide.
• LDEVs are not pool volumes (pool-VOLs).
• LDEVs are not journal volumes.
LUSE operations that handle a path-defined LDEV
You can use an LDEV or another LUSE volume that has path definitions as the top LDEV of the resulting
LUSE volume, and can combine the top LDEV with other LDEVs or LUSEs that have no path definitions.
Creating this type of LUSE volume is referred to as “a LUSE operation that handles a path-defined LDEV.”
When creating a LUSE volume in this manner, the following rules apply:
• You can combine an LDEV or LUSE volume having no path definitions with another LDEV or LUSE
volume having no path definitions.
• You can perform a LUSE operation that handles a path-defined LDEV regardless of how many paths are
defined to the LDEV.
• If you want to use an LDEV or a LUSE volume having no path definitions as the top LDEV of the resulting
LUSE volume, you cannot combine this LDEV or LUSE volume with other LDEVs or LUSE volumes having
path definitions.
When performing a LUSE operation that handles a path-defined LDEV:
• If a path is defined from a Windows 2000
an LDEV, the LDEV can be used for LUSE operations that handle a path-defined LDEV. However, if a
path is defined from a host running another operating system to an LDEV, the LDEV cannot be used for
LUSE operations that handle a path-defined LDEV.
• If a path is defined from a Windows 2000 host or a Windows Server 2003 host to an LDEV and you
want to perform a LUSE operation that handles this path-defined LDEV, verify that the host mode of the
Windows host is 2C (Windows Extension). If the host mode is not 2C, change the host mode to 2C
before performing the LUSE operation.
• If the host mode is 0C (Windows Extension) and an LU path is defined for a volume, you cannot
perform LUSE operations on the volume without unmapping the volume first.
Volume Size Configuration (VSC)
The Volume Size Configuration (VSC) process configures custom volumes (CVs) that are smaller than
normal volumes. Custom volumes improve data access performance by reducing logical device contention
as well as host I/O queue times, which can occur when several frequently-accessed files are located on the
same volume.
® host, a Windows Server 2003 host, or an AIX 5.2 host to
If several frequently-accessed files are on the same LDEV, using VSC to set up smaller, separate custom
volumes for them can reduce conflicts and improve performance.
38 Volume Management for the XP10000/XP12000
A small custom volume can be used as a command device. This leaves the rest of the LDEV free for other
uses.
VSC operations
VSC operations include the following:
• Volume to Space: Formats one or more LDEVs on a selected VDEV into free space, which can be used
to install one or more custom volumes using the Install CV function, or left as free space for future use.
• Install CV: Creates custom volumes from free space.
• Make Volume or Volume Initialize (supported for OPEN-V VDEVs only for XP12000 arrays): Converts a
custom volume back to a normal volume (VDEV).
The Make Volume function clears all custom volumes under a VSC volume and creates an initial volume
(VDEV) that consists of new user-defined custom volumes.
The Volume Initialize function uninstalls all custom volumes under a VSC volume, and reformats the VSC
volume as a normal volume (VDEV).
Compared to other emulation types, use OPEN-V to easily create volumes of any size. OPEN-V volumes
always consist of custom volumes, instead of fixed-size volumes.
CAUTION: VSC operations are destructive. Back up your data before performing VSC operations.
Figure 17 and Figure 18 show a sample VDEV (whose components are LDEVs) in its initial condition and
the VDEV after custom volumes are created.
Figure 17 VSC process (all supported emulation types except for OPEN-V)
Figure 18 VSC process (OPEN-V)
LUN Configuration and Security Manager XP user guide for the XP10000/XP12000 39
Parity group configuration
This section explains the parity group configuration of emulation types other than OPEN-V. OPEN-V
volumes always consist of variable sized volumes instead of fixed-size volumes (FVs). To use OPEN-V,
parity groups must be enabled to support the OPEN-V emulation type. To enable OPEN-V, contact your
HP account support representative.
For emulation types other than OPEN-V, one parity group consists of a maximum of 16 VDEVs. For RAID-5
(7D + 1P) level or RAID-6 (6D + 2P) levels, a maximum of 512 fixed-size volumes (FVs), and a certain
amount of free space are available in one VDEV. For other RAID levels, a maximum of 256 FVs and a
certain amount of space are available. Each VDEV in a parity group has the same configuration, and is
assigned the same FVs of the same size and RAID level.
VSC functions (Volume to Space, Install CV, Volume Initialize, and Make Volume) are performed on each
VDEV. VDEVs are also separated from each other by the boundary limitation. You cannot define a volume
across two or more VDEVs beyond the boundaries.
Figure 19 Parity group configuration for other than OPEN-V
As the result of VSC operations, a VDEV contains fixed volumes, custom volumes, and free spaces that are
delimited in logical cylinders. Sequential free spaces are combined into a single free space.
Figure 20 Virtual VSC volume configuration for other than OPEN-V
40 Volume Management for the XP10000/XP12000
Before changing ordinary target ports or RCU target ports to initiator ports, make sure that no I/Os (such
as Extended Copy commands) are being performed from the host server to the affected ports. You can
change the port type of free ports only.
Volume to Space operation
The Volume to Space function converts one or more LDEVs (fixed or custom volumes) into free space, which
deletes the selected LDEVs from that volume.
Restrictions
• The LDEV must not have a path definition, including TrueCopy (TC390), Continuous Access XP,
ShadowImage (SI390), Business Copy (BC), and Continuous Access XP Journal pair volumes.
• The LDEV must not be a component of a LUSE volume. This applies to all supported emulation types
except for OPEN-V.
• The LDEV must not be reserved for Auto LUN.
• The access attribute must be set to Read/Write.
• The LDEV or LUSE volume must not be a pool volume (pool-VOL).
Install Custom Volume (CV) operation
The Install CV function defines and installs one or more VSC volumes under an existing volume (free space
in a VDEV). You can assign a specific number of physical cylinders (for mainframe systems) or MB (for
open systems) to each VSC volume for maximum control over the volume size.
When you specify the capacity and the emulation type other than OPEN-V for a VSC volume to be
created, the Install CV function automatically creates and formats the VSC volume in sufficient free space.
You must specify a new CU number and LDEV number for the created VSC volume. The created VSC
volume contains the user-specified number of user cylinders and a predetermined number of control
cylinders by the emulation type.
If you select free space and perform an Install CV operation, VSC volumes will be created only in the
selected free space.
For OPEN-V volumes, there are four ways to create VSC volumes (Table 13). You can specify from 46 MB
(50 cylinders) up to the maximum capacity of VDEV for the capacity of a volume. If the specified capacity
exceeds 60 gigabytes (65,535 cylinders), the Install CV function creates the volume in LUSE configuration
automatically.
When there is only one free space in the VDEV, you can use any method to create VSC volumes. When
there are two or more free spaces, you can use the first method only. The other methods are not available.
NOTE: Virtual LUN operations are not available for OPEN-L volumes.

4 Set remaining space as volume Used to create a VSC volume using the remaining space on the VDEV.
NOTE: Volume Management functions are not available for OPEN-L and OPEN-M volumes.

When creating a CV, you can specify the CV capacity. However, there is a margin of error between the
user-specified CV capacity and the actual CV capacity. To estimate the actual CV capacity, use the
following formula. The resulting CV capacity is expressed in megabytes.
↑ (user-specified-CV-capacity + management-area-capacity) × 15 ÷ boundary-value ↑ ×
boundary-value ÷ 1024
NOTE:
• Round up the value enclosed by two up arrows (↑) to the nearest whole number.
• The user-specified CV capacity is expressed in cylinders.
• The management area capacity is expressed in cylinders (see Table 17 on page 46).
• The boundary value is expressed in kilobytes. The boundary value depends on volume emulation types
and RAID levels (see Table 19 on page 46).
Calculating CV capacity for open systems
When creating a CV, you can specify the CV capacity. However, there is a margin of error between the
user-specified CV capacity and the actual CV capacity.
This section explains how to calculate the user area capacity and the entire capacity of a CV. The term
“user area capacity” refers to the capacity of areas in a CV that can contain user data.
Emulation type is OPEN-V
The methods for calculating the user area capacity and the entire capacity of a CV vary depending on the
unit for CV capacity that you specified when creating the CV.
• If the unit for CV capacity is megabytes (MB):
To calculate the user area capacity of a CV, use the following formula. The resulting user area capacity
is expressed in kilobytes.
↑↑ user-specified-CV-capacity × 1024 ÷ 64 ↑ ÷ 15 ↑ × 64 × 15
NOTE:
• Round up the value enclosed by two up arrows (↑) to the nearest whole number.

Volume Initialize and Make Volume operations
The Volume Initialize and the Make Volume functions reset a VDEV to its original configuration.
If you are not using OPEN-V, use the Volume Initialize function. The Volume Initialize function removes all
custom volume areas and free spaces on the VDEV and regenerates and formats initial fixed volumes. The
newly-formatted fixed volumes must be assigned CU and LDEV numbers. Existing fixed volumes on the
VDEV are not reformatted.
If you are using OPEN-V, use the Make Volume function. The Make Volume function deletes all volumes in
a VDEV, and creates new custom volumes according to the specified settings. Table 21 shows the
available settings.
Table 21 Settings for the Make Volume operation (OPEN-V only)
If the specified capacity exceeds 60 gigabytes (65,535 cylinders), the Make Volume function
automatically creates the VSC volume in LUSE configuration.
Restrictions
If the VDEV contains a custom volume that violates any of the restrictions, the Volume Initialize and Make
Volume functions are disabled. You must eliminate invalid custom volumes before performing the Volume
Initialize and Make Volume functions.

48 Volume Management for the XP10000/XP12000
The table contains the following information:
• LDEV: An LDEV status icon (Table 22), a CU number, and an LDEV number. If the selected LDEV is a
LUSE volume, the LDEV number of the top LDEV in the LUSE volume is displayed. An LDEV number that
ends with a # indicates that the LDEV is an external LU (for example, 00:01#).
NOTE: If an LDEV number ends with V (for example, 00:01V), the LDEV is a virtual volume
(V-VOL). For more information about V-VOLs, see the HP StorageWorks Snapshot XP User Guide.
• Emulation: The emulation type of the LDEV. If the selected LDEV is a VSC volume, the emulation type is
displayed together with CVS (for example, OPEN-3 CVS). If the selected LDEV is a LUSE volume, the
emulation type is displayed with an asterisk and the number of volumes in the LUSE volume (for
example, OPEN-E*5). If the LDEVs that comprise a LUSE volume extend over two or more VDEVs, the
emulation type is not displayed with an asterisk and the number of volumes (*n), and each LDEV in the
LUSE volume is displayed.
• Capacity: The capacity of the LDEV in either MB or GV, depending on which unit you selected in the
Capacity Unit box.
• RAID: The RAID level of the LDEV. The RAID level column contains a hyphen (-) when the LDEV is an
external LU or virtual volume (V-VOL).
• PG: A combination of a disk group and a parity group. If the LDEV extends over two or more parity
groups, the PG column displays the smaller parity group number. A parity group number that starts
with a letter E indicates that the parity group consists of one or more external LUs (for example, E1-1).
NOTE: If a parity group number starts with V (for example, V1-1), the parity group consists of one
or more virtual volumes (V-VOLs).
• Paths: The number of paths that is set for the LDEV. If this column displays the number of paths for an
LDEV, you can use the LDEV as the top LDEV of a LUSE volume. For more information, see ”LUSE
operations that handle a path-defined LDEV” on page 38.
• Access Attribute: The access attribute that is set for the LDEV
• IO Suppression: Displays Disable when the I/O request from the host is suppressed, or Enable if the
I/O request from the host is not suppressed
• Cache mode: Displays Disable when the cache is not set to be used for responding to the I/O request
from the host, or Enable when the cache is set to be used for responding to the I/O request from the
host
• Ex-Dev Info.: Displays the drive type of the LDEV. Displays an asterisk (*) when the drive type is SATA.
Nothing is displayed when the drive type is not SATA.
• CLPR: The ID of the CLPR (cache logical partition) to which the displayed volumes belong. The CLPR ID
is a CLPR number (two-digit) and a CLPR name (16 characters maximum)
• Selected LDEVs: The number of LDEVs selected in the LDEV Information table
• Capacity Unit button: Select a capacity unit (GB or MB) to describe LDEVs

volume.
Free LDEVs table
Lists the LDEVs, VSC volumes, and LUSE volumes that can constitute a LUSE volume in combination with the
LDEV selected as a top LDEV in the Select an LDEV list. The table contains the following information:
• LDEV: An LDEV status icon (Table 22), a CU number, and an LDEV number. If the selected LDEV is a
LUSE volume, the LDEV number of the top LDEV in the LUSE volume is displayed. An LDEV number that
ends with a # indicates that the LDEV is an external LU (for example, 00:01#).
NOTE: If an LDEV number ends with V (for example, 00:01V), the LDEV is a virtual volume
(V-VOL). For more information about V-VOLs, see the HP StorageWorks Snapshot XP User Guide.
• Capacity: Capacity of the LDEV represented in units (GB or MB), based on the capacity you indicate
with the Capacity Unit box.
• RAID: RAID level of the LDEV. The RAID level column contains a hyphen (-) when the LDEV is an external
LU or virtual volume (V-VOL).
• PG: A combination of the disk group and the parity group. If the LDEV extends over two or more parity
groups, the PG column displays the smaller parity group number. A parity group number that starts
with a letter E indicates that the parity group consists of one or more external LUs (for example, E1-1).
NOTE: If a parity group number starts with V (for example, V1-1), the parity group consists of one
or more virtual volumes (V-VOLs).

”Creating a LUSE volume using the LDEV information table” on page 52.
Each LDEV or LUSE volume that you want to add must have the same capacity as each LDEV in a LUSE
volume to be expanded.
• Reducing LUSE capacities
You may not reduce the capacity of an existing LUSE volume. If you want a LUSE volume to have a
smaller capacity, you must release and then redefine the LUSE volume.
Resetting an unregistered LUSE volume
When you create a LUSE volume, the screen shows the changes in blue bold italics until you register the
volume into the disk array by clicking Apply. The LUSE volume in blue bold italics indicates that you can
reset this LUSE volume to the state before it was created.
If the XP disk array has firmware version 21.06.22 or later installed, you can reset an unregistered LUSE
volume to the state before it was created. However, you cannot recover any LUSE volumes that have been
released already to the state when they were created. If the LUSE volume that you have created consists of
any LDEVs (those in blue bold italics) that have once been released from a different LUSE volume, you can
only reset your LUSE volume to the state when the constituting LDEVs were released from the other LUSE
volume.
1. In the Volume Management pane, select the CU number from which you want to reset an unregistered
LUSE volume. The LDEV Information table shows all LDEVs that the selected CU contains.
2. In the LDEV Information table, right-click an unregistered LUSE volume (displayed in blue bold italics)
and select Reset Selected Volume. A confirmation message appears.
3. Verify the information in the dialog box and click OK. The unregistered LUSE volume will be reset to the
state before this LUSE volume was created. The LDEV Information table displays the LUSE volumes or the
LDEVs constituting the selected LUSE volume that has just been reset.

Making external mainframe volumes usable
To use external volumes with the XP10000/XP12000, you must usually use External Storage XP to perform
external volume mapping, and then use Volume Management’s Format or Format All command to format
the volumes (see ”Formatting LDEVs” on page 71). However, when you format external mainframe volumes
in this way, the formatting operation might take a lot of time.
If you use the following procedure, you can make external mainframe volumes usable more quickly.
CAUTION: Only storage administrators can perform the following operation. Storage partition
administrators cannot perform this operation.
1. Zero-format external mainframe volumes.
LUN Configuration and Security Manager XP user guide for the XP10000/XP12000 73
NOTE: The term “zero-formatting” refers to a formatting operation that writes the number 0 (zero)
to the entire disk area. For more information about zero-format volumes, see the documentation for
the mainframe system or external disk array you are using.
2. Use External Storage XP to map the zero-formatted external volumes and register the volumes in an
external volume group. For more information, see the HP StorageWorks External Storage XP Users
Guide.
CAUTION: Ensure that the external volume group does not include volumes that are not
zero-formatted. If an external volume group includes volumes that are not zero-formatted, the
volumes are blocked when you perform the operation described in the next step. Therefore, hosts
cannot read from or write to the volumes. If you have not zero-formatted external volumes but you
want to make the external volumes usable with the XP 10000/XP12000, use Volume
Management’s Format or Format All command.
3. Use Volume Management to specify the external volume group, and overwrite control blocks in the
volumes in the specified external volume groups. After overwriting finishes, the external volumes are
usable with the XP10000/XP12000.
NOTE: Control blocks are a type of area in a volume that contains information other than user
data. Information required for managing a volume is recorded in control blocks.
To overwrite control blocks in volumes in an external volume group
1. On the Customized Volume tab, right-click the LDEV folder at the top of the tree.
2. Select Write to Control Blocks.
3. In the Write to Control Blocks pane, select the desired external volume group from the Candidate ExG
list, and click Add.
The selected external volume group moves to the Target ExG list.
NOTE:
• You can select one or more external volume groups.
• To remove external volume groups from the Target ExG list, select the external volume groups
from the list, and click Delete. The external volume groups move to the Candidate ExG list.
4. Click OK to close the Write to Control Blocks pane.
5. Click Apply on the Customized Volume tab.
A message appears asking if you want to continue the operation.
CAUTION: Cancel the operation if the external volume group includes volumes that are not
zero-formatted. If you continue the operation, hosts cannot access the volumes.
6. To continue the operation, click OK to close the message.
Volume Management starts overwriting the control blocks.
Operational restrictions
The success of some volume management activities depends on the status of the security switch and
whether I/O is active or inactive to the port or LUN. The following tables describe those restrictions.
