HP XP Array Manager Software - Manual (Page 17)

If two or more volumes are combined into a LUSE volume, Data Retention Utility displays the top LDEV,
but does not display other LDEVs (other volumes) that are combined into the LUSE volume. For example,
if three volumes 03, 04, and 05 in the CU 01 are combined into a LUSE volume, the volume list in
the Data Retention window displays the volume number 03, but does not display 04 and 05. To view
all volumes that form a LUSE volume, see “
Viewing a List of Logical Volumes Combined into a LUSE
Volume ” on page 25.
Table 3 Volume List Details
Description Item
Displays volume numbers with the following icons :
•
Indicates a volume that has the Read/Write attribute.
•
Indicates a volume that has the Read Only attribute.
•
Indicates a volume that has the Protect attribute.
Notes:
• If # is displayed to the right of a volume number, the volume is an external volume. If V is
displayed to the right of a volume number, the volume is a virtual volume. If X is displayed
to the right of a volume number, the volume is a virtual volume for XP Thin Provisioning
Software.
• If two or more volumes are combined into a LUSE volume, the Data Retention Utility considers
the combined volumes as a single unit.
LDEV
Indicates the access attribute of each volume. These values can also be assigned using RAID
Manager.
Attribute
Displays volume emulation types. If an asterisk and a number appear to the right of an emulation
type, the volume is a LUSE volume. For example, OPEN-V*36 indicates a LUSE volume in which
36 volumes are combined.
Emulation
Displays the capacity (in gigabytes) of each volume; this value is shown to two decimal places. Capacity
Indicates whether the volume can be specified as a secondary volume (S-VOL), which is a copy
destination volume for storage system copy operations (for example, XP XP Business Copy
Software, XP XP Continuous Access Software). You can also use RAID Manager to specify
whether each volume can be used as a secondary volume.
S-VOL
Indicates by a hyphen or the letters RAID Manger which tools can be used to set the LU path
settings and command device settings.
• A hyphen (-) indicates that RAID Manager and Remote Web Console can be used to make
LU path settings and command device settings. LUN Manager is required when you use
Remote Web Console to make these settings.
• RAID Manager indicates that RAID Manager can be used to make LU path settings and
command device settings, but Remote Web Console cannot be used to do so.
Reserved
Displays the period (in days) when you are prohibited from changing access attribute to
Read/Write. For example, if 500 days is displayed, attempts to change access attribute to
Read/Write are prohibited in the next 500 days. If Unlimited is displayed, the retention term
is extended indefinitely. If the retention term is 0 days, you can change access attribute to
Read/Write. During the retention term, you can change Read Only to Protect, or vice versa.
Caution: Using Data Retention Utility, you can extend the retention term of the volume, but cannot
shorten the retention term. For details on how to extend the retention term, see “
Extending the
Data Retention Term ” on page 20. If you need to shorten the retention term, you must ask your
HP service representative to do so.
Retention
Term
Displays the number of LU paths to each volume. Paths
