EXAMPLES The following example shows how to use the tunetpvv command to change the RAID type of a TPVV (testvol) from cpg1, which is originally cpg1, which is of RAID 1. Task 1 started. The following example shows how to use the tunetpvv command to increase the availability level of a TPVV (testvol). Note that there is mag availability because testvol was originally on cpg1, which is created with option (-ha mag). To increase cage availability, create a CPG with cage availability and tune testvol to the associated CPG. cli% createcpg cpg3 cli% tunetpvv -cpg cpg3 testvol Are you sure you want to tune VV 'testvol'? select y=yes n=no: y Task2 started. The following example shows how to tune multiple VVs together. Testvol.0, testvol.1 and testvol.2 are the three VVs to be tuned: cli% tunetpvv -cnt 3 testvol Are you sure you want to tune VV 'testvol'? select y=yes n=no: y Task 3 started. NOTES When canceling a tunetpvv command task, the canceltask command may return before a cancellation is complete. Thus, resources reserved for the task may not be immediately available. This will prevents actions like attempting another tune on the same VV. Scripts should use the waittask command in order to ensure orderly completion of the tunetpvv command cancellation prior to taking other actions. tunetpvv 655
