Introduction
LUN Configuration Manager XP enables you to define the SCSI-to-logical
device (LDEV) paths for the disk array using the remote console PC. Each
LDEV can be mapped for access from multiple ports or multiple target IDs
to provide alternate paths for continuous data availability.
LUN Configuration Manager XP allows you to reconfigure the SCSI/Fibre
Channel paths at any time to optimize disk array performance and
accommodate system configuration changes, such as adding a host.
To maximize data access capabilities, the logical unit size expansion
(LUSE) feature allows you to create virtual logical units that are larger than
standard LUNs. These logical units can also be released.
Introduction 13
Installation requirements
See your HP account representative for specific requirements.
The system requirements for the LUN Configuration Manager XP software
are as follows:
• HP StorageWorks Remote Control XP installed on system
• LUN Configuration Manager XP software license keys needed to
enable the feature—LUNM and LUSE
• HP Surestore Disk Array
• Remote console PC with Windows 95, Windows 98, Windows NT,
Windows 2000, or Windows XP
14 HP StorageWorks LUN Configuration Manager XP: user’s guide
Important terms and concepts
You should be familiar with the following terms and concepts:
• controller
The disk array has one controller which controls data access and
storage operations. The disk array controller supports OPENemulation modes.
• CU (control unit)
Each CU controls up to 256 LDEVs (XP256) or 512 LDEVs (XP512).
The CUs are numbered sequentially from 0 to E.
• LDEV (logical device)
An LDEV results when a RAID group is divided into parts according
to the emulation mode selection (OPENLDEVs depends upon the selected emulation mode.
• parity group
A parity group is a set of hard disk drives that have the same capacity
and are treated as one group. For example, a parity group of 18-GB
disk drives in a RAID5 configuration consists of four disk drives
(three data and one parity).

•volume
An LDEV can also be called a volume. The LDEV ID is internal to the
disk array and is not related to the volume serial number (volser) or
LUN number.
•path
A SCSI or Fibre Channel port ID, a SCSI target ID (TID), and a LUN
number.

HP StorageWorks LUN Configuration Manager XP: user’s guide
Adding and deleting SCSI/Fibre Channel paths
LUN management operations on the remote console PC enable you to add
and delete paths to LDEVs in the array. Each LDEV can have multiple
paths defined to support failover or load-balancing configurations.
Caution Before assigning a SCSI path to a LDEV, make sure that the LDEV is not an
Auto LUN XP Reserved Device. If the volume has been reserved, it will be
write-protected and any writes to that volume will fail. Use Auto LUN XP to
verify the reserve status of the LDEVs.
Adding SCSI/Fibre Channel paths
SCSI and Fibre Channel paths can be added in both online (with concurrent
I/Os) or offline (no I/O) modes.
To add SCSI/Fibre Channel paths:
1. Select either online or offline mode from the RMSCSI Path menu.
Operation 27
2. Review the information displayed on the LUN Management-LDEV
Configuration window to see which paths have already been assigned.
A single plus sign (+) next to an LDEV ID (listed under the Volume
attribute) indicates that there is an assigned SCSI/fibre path to that
LDEV. Two plus signs (++) next to an LDEV ID indicates that there is
more than one SCSI path to that LDEV. The label for CMD.Dev next
to an LDEV ID indicates that volume is being used as a command
device and is not available for SCSI path definition.
28
3. Select Add to open the Set SCSI Path Parameter window.
HP StorageWorks LUN Configuration Manager XP: user’s guide
4. Paths can be defined individually (individual mode) or in a group (bulk
mode).
(Individual Mode) Select PORT, SCSI ID, and LUN one by one for
each LDEV ID.
(Bulk Mode) Select the desired CU number; then select the SCSI ports,
TIDs, and LUN IDs you want to assign; and then select the corresponding LDEV IDs. Select the first LDEV ID and LUN Manager
assigns the remaining paths sequentially, or select the specific LDEV
IDs you want to assign.
A bulk mode operation will fail if the number of LUNs defined
exceeds the number of LDEVs available.
To calculate the number of LUNs to select, multiply the number of
selected ports, the number of selected SCSI TIDs, and the number of
selected LUN IDs. For example, if you select one port, four SCSI
TIDs, and two LUN IDs, you must select eight LUNs (1 × 4 × 2 = 8).
Operation 29
5. When you have completed setting the paths, select Set.
The Add SCSI Path window opens and displays the SCSI paths to be
added.

Operation 59
Note the following limitations:
• You cannot combine LDEVs from different control units.
• Windows NT hosts cannot access more than 32 logical units.
• Some operating systems may experience slow disk access times with
large logical units.
The following are guidelines for LU Size Expansion:
• A maximum of 256 expanded LUNs can be configured on the same
port.
• The LDEVs that will become members of the LUSE must not have
SCSI paths assigned. These are known as free (or available) LDEVs.
• To make an LDEV free, it must have its SCSI paths deleted, which
requires that it be offline (unmounted from all hosts).
• Combining nonsequential LDEVs into a LUSE is supported, provided
they are on the same CU.
• Combining customized volumes into a LUSE is supported, provided
they have the same size, emulation type, and CU. The order of
operations is important: you must first create the volumes, and then
combine those volumes into a LUSE volume.
60
• Combining customized volumes and normal volumes into the same
LUSE is not supported.
• Combining command devices into a LUSE is not supported.
• Combining RAID1 and RAID5 into the same LUSE is not supported.
• Combining emulation types (OPEN-x) into the same LUSE is not
supported.
• Factors relevant to recommended LUSE size include the following:
Some operating systems may exhibit slow disk access times with large
logical units if they contain too many high usage files. The size of a
LUSE can also affect the amount of time required to perform backups.
• The queue depth for open systems can vary depending on the platform.
HP StorageWorks LUN Configuration Manager XP: user’s guide

VSC operations
Volume Size Configuration (VSC) allows you to configure custom size
volumes that are smaller than normal volumes. VSC improves 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. VSC enables better utilization of the physical
storage capacity of the disk array while reducing the amount of
administrative effort required to balance storage device I/O work loads.
VSC can be used in conjunction with Cache LUN XP while maintaining
flexibility in the cache configuration.
VSC operations can be performed by users with administrator or custom
VSC access privileges. Users without administrator or VSC access
privileges can only view the VSC configuration information for each
attached disk array. VSC operations can only be performed when the VSC
option is enabled.
The procedures for performing VSC operations are different depending on
whether you have an XP256 or and XP512. The procedures are divided into
two sections. Make sure you are using the correct set of instructions.
VSC operations 79
This chapter covers VSC parameters and procedures. The chapter contains
three sections:
• “VSC parameters” (page 81)
• “XP256 VSC operations” (page 83)
• “XP512 VSC operations” (page 113)

VSC parameters
This section covers
• VSC specifications
• custom volume capacity
• storage subsystem ID (SSID) requirements
VSC specifications
The following table lists VSC specifications. Each CV has its own assigned
unit control block (UCB), and multiple VSC types can be configured within
each parity group. The user can add and delete VSC at any time and has
complete control over the number of user cylinders and the emulation type
of each CV.

Storage subsystem ID (SSID) requirements
Each CU contains four logical subsystems, each of which contain 64
logical devices. It may be necessary to specify an SSID when creating
custom volumes. Any value can be used for the SSID of OPEN-x devices.
The only constraint is that the lowest SSID number used must be evenly
divisible by four.

HP StorageWorks LUN Configuration Manager XP: user’s guide
XP256 VSC operations
The first step in performing VSC operations is to convert one or more
normal-size volumes to VSC volumes. When you convert a normal volume
to a VSC volume, all of the logical blocks in the volume become available
for use in custom size volumes (CVs). You can define the first CU during
the normal-to-VSC conversion process, and you can define additional CVs
as needed under that VSC volume up to a maximum of 32 volumes per
parity group (array group) using the install CV process.
If your disk array was configured with one or more VSC volumes during
installation, you can bypass the normal-to-VSC conversion process and
begin installing new CVs immediately.
VSC operations include:
• viewing the current VSC information
• converting a normal volume to a VSC volume
• installing a CV
• deinstalling a CV
• converting a VSC volume to a normal volume
The following operations are for the XP256 only.
VSC operations 83
