2. Tune the user space of the volume by issuing the tunevv usr_cpg command, where: • usr_cpg is the name of the CPG created previously in Step 1, indicating the user space of the new CPG will be used. • is the fully-provisioned virtual volume you are modifying. 3. Tune the snapshot space of the volume by issuing the tunevv snp_cpg command: • snp_cpg indicates the CPG to where the snapshot space is moved. • is the fully-provisioned virtual volume you are modifying. Changing Virtual Volume Fault-Tolerance Levels Thinly-Provisioned Virtual Volumes To change the volume fault-tolerance level of a TPVV, perform the following: 1. Create a new CPG with the desired fault-tolerance level and RAID type. See "Creating a Common Provisioning Group" (page 80) for instructions. 2. Change the TPVV's fault-tolerance level by issuing the tunevv usr_cpg command, where: • usr_cpg is the name of the CPG created previously in Step 1. • is the TPVV you are modifying. Fully-Provisioned Virtual Volumes To change the volume fault-tolerance level of a fully-provisioned virtual volume, perform the following: 1. Create a new CPG with the desired fault-tolerance level and RAID type. See"Creating a Common Provisioning Group" (page 80) for instructions. 2. Change the fully-provisioned virtual volume's fault-tolerance level by issuing the tunevv usr_cpg command, where: • usr_cpg is the name of the CPG created previously in Step 1. • is the fully-provisioned virtual volume you are modifying. 3. Tune the snapshot space of the volume by issuing the tunevv snp_cpg command: • snp_cpg indicates the CPG to where the snapshot space is moved. • is the fully-provisioned virtual volume you are modifying. Changing Virtual Volume Parameters Thinly-Provisioned Virtual Volumes To change the parameters of a TPVV, perform the following: 1. Create a new CPG with the parameters you wish to apply to the volume. See "Creating a Common Provisioning Group" (page 80) for instructions. 2. Issue the tunevv usr_cpg command, where: • usr_cpg is the name of the CPG created previously in Step 1. • is the TPVV you are modifying. Fully-Provisioned Virtual Volumes To change the parameters of a fully-provisioned virtual volume, perform the following: 176 Performance Tuning
