HP XP20000XP24000 Disk Array - Manual (Page 32)

• An estimated usage rate for the parity group after a proposed volume migration.
If you specify an external volume as a source volume, Auto LUN cannot calculate the estimated
usage rate after migration. In this case, a hyphen (-) appears instead of a value.
• Target (Reserved) LDEV lets you specify the target volume (that is, the location to which you
want to migrate the source volume). On the right of the text box is the following:
• The current usage rate for the parity group that the target volume belongs to.
• An estimated usage rate for the parity group after a proposed volume migration.
If you specify an external volume as a target volume, Auto LUN cannot calculate the estimated
usage rate after migration. In this case, a hyphen (-) appears instead of a value.
• The line graph illustrates the past usage rates of the source volume and the target volume.
• The
Close button closes the Graph window.
• The Set button adds a new manual migration plan to the list. The new manual migration plan
consists of the volumes selected in Source LDEV and Target (Reserved) LDEV.
• List: Each row in the list indicates a manual migration plan, which is a pair of a source volume
and the corresponding target volume, created in the Manual Plan window. A migration plan
before being applied to the storage system is displayed in blue, and a migration plan after
being applied (or during execution) to the storage system is displayed in black. Auto LUN
performs multiple migration plans concurrently. When a migration plan was finished, the plan
will disappear from the list.
A migration plan being executed by a program other than Auto LUN (such as RAID Manager) is
also displayed in the list all together. Migration plans executed by other programs are not erased
from the list automatically until the user operates for finish by using the program that performed
the volume migration.
The Stat column displays an error code if an error occurs during execution of a migration plan. To
view detailed information about an error, select and right-click the error code and then select
Detail from the pop-up menu.
The DEL column displays the character D if you attempt to delete a migration plan that is waiting
for execution, or already in progress. Migration plans indicated by D are actually deleted when
you click the Apply button.
The % column indicates the progress of the manual migration. The progress value is updated
once per minute.
The Source LDEV columns display information about source volumes:
• LDEV indicates the volume ID. The number on the left of the first colon (:) from the left is the
LDKC number. The number on the left of the second colon (:) from the left is the CU image
number. The number on the right of the second colon is the LDEV number. To the left of the
device ID, the
icon is displayed which indicates that the volume is being migrated or
is registered in a migration plan.
• Emulation indicates the emulation type of the volume.
• Capacity indicates the capacity of the volume.
• RAID indicates the RAID type.
• PG indicates the parity group ID or the external volume group ID. The number before the
hyphen (-) is the frame number. The number after the hyphen is the group number.
Note: If the indicated parity groups are the concatenated parity groups, this item only displays
the ID of the parity group at the top of the concatenated parity groups.
• HDD indicates the type of the hard disk drive.
• CLPR indicates the number and name of the CLPR corresponding to the parity group in the
format CLPR-number:CLPR-name. For details on CLPRs, see HP StorageWorks XP24000
Disk/Cache Partition User’s Guide.
The Target LDEV columns display information about target volumes:
• LDEV indicates the volume ID. The number on the left of the first colon (:) from the left is the
LDKC number. The number on the left of the second colon (:) from the left is the CU image
number. The number on the right of the second colon is the LDEV number. The blue
icon
indicates a reserved volume of Auto LUN. The green icon indicates a reserved volume
of other programs.
