Table 8-1 Open-Allocated Group Information under All Storage/My Storage
Column Description
% Used Displays the volume usage. The unit is %.
This item is updated when the Device Manager agent reports the volume usage to the Device
Manager server.
Use the following expression to obtain the storage usage:
Amount of used file system capacity established on the target storage ÷ storage capacity x 100 (%)
The usage cannot be calculated when the values required for calculation are incorrectly obtained. In
this case, -- displays. To calculate the usage, check the following conditions:
• The Device Manager agent is running on the host. When the Device Manager agent is not
running, the usage is displayed as blank.
• When Windows ® is used for the platform of the host using the storage: When the following
conditions are satisfied, -- displays. Otherwise, the usage is displayed.
• A drive letter has not been assigned to the LU.
• The LU has not been directory-mounted.
• The LU has multiple partitions and, among the disks in the LU, there is a disk to which a
drive letter has not been assigned or that has not been directory-mounted. However, when
the LU or a partition of the LU is under dynamic disk control, or when the LU is managed by
VxVM, -- might appear.
• When Solaris™ is used for the platform of the host using the storage: When the following
conditions are satisfied, -- displays. Otherwise, the usage is displayed.
• The target LU has been incorporated into a volume manager (VxVM, SVM, or SDS).
• The LU has not been mounted.
• When Linux ® is used for the platform of the host using the storage: When the following conditions
are satisfied, -- displays. Otherwise, the usage is displayed.
• The target LU has been incorporated into a volume manager (LVM).
• The LU has multiple partitions and part of the LU (even one partition) has been incorporated
into a volume manager.
• The LU or part of the LU that has multiple partitions has not fully been mounted.
• When HP-UX or AIX ® is used for the platform of the host using the storage: The usage is not
displayed, -- displays.
One LU might have multiple values for the usage % Used. If so, please note the following:
• If storage is identified concurrently by more than one host, Web Client displays the usage of
the storage for the host (the Device Manager agent) that reported the most recent data. The
host that reports the most recent information may report the usage of the storage as --. In
this case, the usage is displayed as -- even if another host is using the storage, unless that
host reports the storage usage.
• If storage is identified as multiple devices by a single host, the largest value from the multiple
devices is displayed as the storage usage.
Volume Attr Displays volume attribute for LUN Expansion (LUSE), Virtual LVI/LUN (CVS), Snapshot XP.
•
LUSE
= LUSE volume
•
CVS
= Volume created with the Virtual LVI/LUN (or CVS) function
•
LUSE (CVS) = LUSE volume consisting of CVS volumes
•
V-VOL = V-volume used in Snapshot XP
•
JNL-VOL = Continuous Access XP Journal journal volume
•
POOL = Snapshot XP data pool volume
•
GUARD
= LUN Security XP Extension volume
•
External
= External volume
•
IO Suppression
= Volume to which an external volume is mapped, and for which the host I/O
suppression mode is enabled
•
CacheEnable = Volume to which an external volume is mapped, and for which the I/O cache
mode is enabled
•
None = Ordinary volume.
Use this for filtering. You can use a partial match specification as a condition for filtering
CMD DEV Displays whether the LDEV is a command device (CMD DEV, or blank).
