HP P9000 Command View Advanced Edition Suite Software 7.2 CLI Reference Guide

For XP24000/XP20000, if no SSID is assigned to devNum of the created THP volumes, one is assigned
automatically. For details about the SSID, see the storage system documentation.
If you use this command with P9500, the virtual parity group and the virtual volumes must satisfy the
following conditions:
• When a THP pool is specified, its status must not be Blocked.
• When a THP pool is specified, the over-provisioning percent must be less than the over provisioning
limit threshold.
NOTE:
If you use this command with P9500, you cannot create more than one THP volume in a virtual parity
group.
If you use this command with XP24000/XP20000, the virtual parity group and the virtual volumes
must satisfy the following conditions:
• They must have an emulation type of OPEN-V.
• The unused capacity on the virtual volume must be larger than the capacity of the volumes for Thin
Provisioning Software.
• If you are creating virtual volumes in an existing virtual group, the CLPR number of any pool for
Thin Provisioning Software that you specify must be the same as the CLPR number of the virtual
parity group.
• When a for Thin Provisioning Software is specified, its status must not be Blocked.
• When a for Thin Provisioning Software is specified, the over-provisioning percent must be less
than the over provisioning limit threshold.
NOTE:
Note the following when using this command with XP24000/XP20000:
• HP recommends that you do not create more than one volume for Thin Provisioning Software in
a virtual parity group. Also, if the microcode version is 60-04-XX-XX/XX or later and the system
option 726 is set to ON, you cannot create more than one volume for Thin Provisioning Software
in a virtual parity group.
• Because a volume for Thin Provisioning Software management area is created, you cannot create
volumes for Thin Provisioning Software that have a total capacity equal to the unused capacity in
the virtual parity group.
• To create virtual volumes within an existing virtual parity group, you must have Open Volume
Management installed in the storage system.
• If you execute this command when the threshold values related to the over-provisioning percent
(the over provisioning warning threshold and over provisioning limit threshold) are set, make sure
that the Device Manager server database is consistent. These threshold values are specific thresholds
managed by the Device Manager server. If the over-provisioning percent information that has
been obtained by Device Manager does not match the actual over-provisioning percent, the system's
determination of whether the over provisioning warning threshold and over provisioning limit
threshold values have been exceeded might be incorrect.
For details about the following conditions, see the Thin Provisioning documentation:
• The minimum and maximum capacities of THP volumes
• The number of THP volumes that you can create in a single virtual parity group
