ModifyPool

ModifyPool expands a THP pool or changes the settings related to the THP pool.

NOTE:

• This command can be used only with P9500 and XP24000/XP20000.

• The attributes of the Pool instance, thresholdVolForewarn and thresholdVolOverwarn,

which were output as the execution results of this command, have changed to overProvision-

ingWarning and overProvisioningLimit, respectively. Check and, if necessary, revise

the script settings that you use in version 6.3 or later.

To expand a THP pool, the following conditions must be satisfied:

• The conditions on logical units to be specified as pool volumes, which are listed in “Ad-

dPool” on page 65.

• For P9500 or XP24000/XP20000, the status of the THP pool is not Blocked and the usage rate

is not 100%.

With P9500 or XP24000/XP20000, if you want to change the settings related to a THP pool, the

following conditions must be satisfied:

• If the status of the THP pool is Normal, the usage rate is less than 95%.

• When changing the threshold value, you specify a value that is larger than the value set for the

usage rate of the THP pool at that time.
