Auto LUN XP for the XP12000/XP10000
• CLPR: Number and name of the CLPR that corresponds to the parity group to which the logical 
volume belongs, in the format CLPR number:CLPRname. For more information about CLPRs, see the 
HP StorageWorks XP Disk/Cache Partition user guide.
• Owner: Program that reserved the volume. If Auto LUN XP reserved this volume, USP is displayed. If 
another program reserved this volume, Other[XX] is displayed, where [XX] is the program ID. If this 
volume is not reserved and is a normal volume, a hyphen (-) is displayed.
Reserving target volumes
To migrate volumes, you must reserve logical volumes as migration destinations (targets) regardless of the 
migration method (manual or automatic). Migration will not take place if no logical volume is reserved.
NOTE:
The term reserved volume refers to a volume that is reserved for use as a migration destination. 
Reserved volumes are denoted by blue   icons. The term normal volume sometime refers to a volume that 
is not reserved as a migration destination.
1.
In the Auto LUN pane, click Physical.
2.
Click Plan. The Manual Migration tab appears.
3.
Click Attribute. The Attribute tab appears.
4.
In the Attribute tree, locate a logical volume to use as a migration destination. First click an HDD class 
to display a list of parity groups in that class. Next, click a parity group to display a list of logical 
volumes in that group.
5.
In the table on the right, locate logical volumes preceded by the 
 or   icons. From those logical 
volumes, choose the logical volume, and right-click.
6.
Click Reserved LDEV. The icon changes to  .
7.
Click Apply. The settings in the pane are applied to the disk array. The specified logical volume is 
reserved as a migration destination.
If you right-click a logical volume preceded by the   icon (reserved volume) and click Normal LDEV, the 
icon changes to  , and you cannot use the volume as a migration destination. This procedure does not 
work when the logical volume is preceded by the green Reserved icon, which indicates another program 
reserved the volume.
Setting (fixing) parity groups
The auto migration function excludes fixed parity groups. However, volumes in a fixed parity group can be 
used for manual migration operations.
1.
In the Auto LUN pane, click Physical.
2.
Click Plan. The Manual Migration tab appears.
3.
Click Attribute. The Attribute tab appears.
4.
In the tree, double-click an HDD class folder.
The table on the right displays a list of parity groups in the HDD class. An icon indicates parity groups 
that can include source or target volumes. A different icon indicates fixed parity groups, which cannot 
include source nor target volumes.
