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
You need specify this parameter only if true is specified for the assign
parameter.
