Command line interface commands

NOTE: This command can be used only with XP24000/XP20000 storage subsystems.

Format when the command is used to assign THP volumes to a THP pool:

hdvmcli [URL] ModifyVirtualVolume model=model serialnum=serial-number assign=true

devnums=device-number-of-THP-volume poolid=pool-ID-of-THP-pool [threshold=usage-rate-

threshold-of-THP-volumes]

Format when the command is used to release the assignation between THP volumes and a

THP pool:

hdvmcli [URL] ModifyVirtualVolume model=model serialnum=serial-number assign=false

devnums=device-number-of-THP-volume

Format when the command is used to change the usage rate threshold of THP volumes:

hdvmcli [URL] ModifyVirtualVolume model=model serialnum=serial-number

devnums=device-number-of-THP-volume threshold=usage-rate-threshold-of-THP-volumes

This command can be used with a THP volume that satisfies the following conditions:

• If you are assigning a THP volume with a THP pool, the THP volume must not already be

assigned to a THP pool.

• If you are releasing a THP volume from a THP pool, or if you are only changing the threshold

value, the THP volume must already be assigned to a THP pool.

• If you are releasing a THP volume from a THP pool, it must not have a path.

NOTE: For details about the number of THP volumes that can be assigned to a single THP pool,

see the XP Thin Provisioning Software documentation.

Table 4-56 ModifyVirtualVolume command parameters

Parameter Name Status Description

model Required Model of the storage subsystem

serialnum Required Serial number of the storage subsystem

assign Optional

Specify true to assign THP volumes to a THP pool.

Specify false to release THP volumes from a THP pool.

Omit this parameter if you are changing the threshold value.

devnums Required Device number(s) of THP volume(s)

Specify this parameter as a decimal number or colon-delimited

hexadecimal number in the format ww:xx:yy, where ww is the LDKC

number, xx is the CU number, and yy is the LDEV number. ww is optional.

If ww is omitted, LDKC is assumed to be 0.

Use a comma to delimit multiple values.

poolid Optional Pool ID of the THP pool
