HP P9000 Command View Advanced Edition Suite Software 7.4.0-00 CLI Reference Guide (TB581-96326, December 2012)

You need to specify at least one of the following parameters: highdevnums, middledevnums,
or lowdevnums.
Parameter values to obtain in advance
serialnum and model
Obtain these values from the execution result of the GetStorageArray command. In the execution
result, use the arrayType value or the displayArrayType value to specify the model para-
meter, and use the serialNumber value to specify the serialnum parameter.
poolid
Obtain this value from the execution result of the GetStorageArray (subtarget=Pool)
command. When you execute this command, specify values that have been obtained in advance
for the serialnum and model parameters, and then specify 5 (Thin Provisioning) for the
poolfilter parameter. In the execution result of this command, the poolID values appear
under An instance of Pool. Select the THP/Smart pool that the THP/Smart pool volume
belongs to, and then specify the corresponding poolID value for the poolid parameter.
highdevnums, middledevnums, and lowdevnums
Obtain this value from the execution result of the GetStorageArray (subtarget=Pool,
poolsubinfo=LogicalUnit) command. Execute this command by specifying only the model
and serialnum parameters, Pool for the subtarget parameter, and LogicalUnit for the
poolsubinfo parameter. In the execution result of this command, the devNum value of Logic-
alUnit appears under An instance of LogicalUnit. Specify the devNum value of a lo-
gical unit, for which the external LDEV tier rank is changed from the THP/Smart pool volume in
a THP/Smart pool, to a parameter such as highdevnums, middledevnums, or lowdevnums.
Command execution example
In this example, the external LDEV tier rank of the THP/Smart pool volume (devNum: 00:18:CB) that
constitutes the Smart pool (poolid: 57) of the storage system (serial number: 53039, model: P9500)
is changed to High.
hdvmcli ModifyExternalTierRank -o "D:\logs\ModifyExternalTierRank.log"
