HP 3PAR OS 3.1.3 Command Line Interface Reference

EXAMPLES
The following example sets the IOPs Min Goal and Max Limit of vvset vsa to 300:
cli% setqos -io 300 vvset:vsa
The following example turns off the QoS scheduling for vvset vsa:
cli% setqos -off vvset:vsa
The following example removes all QoS settings of all vvsets:
cli% setqos -clear vvset:*
NOTES
Maximum limit — this is the maximum amount of IOPS or bandwidth, or both, which a given VVset
or Domain is allowed to achieve. Best practice is to use the System Reporter data in order to
quantify the volumes performances and set QoS rules accordingly.
Minimum goal — this is the minimum amount of IOPS or bandwidth, or both, below which the
system will not throttle a given VVset or Domain in order to meet the latency goal of a higher
priority workload. These VVsets or Domains may consume more IOPS/bandwidth than what the
goal is (up to the Max if set), but will be throttled to the given goal as the system gets busier.
Latency Goal — this is the Svctime goal the system will target to fulfill for a given QoS rule. In order
for the goal to work, rules with an minimum goal must exist so the system can throttle those
workloads.
Three Priority Levels exists: High, Medium, and Low. As the system gets busier it will start targeting
lower priority workloads and throttling their performances in order to meet higher priority workloads
latency goals. High priority level should be used against critical applications, lower priority on
less critical applications.
For all the <pattern> fields, the patterns are glob-style (shell-style) patterns (see help on
sub,globpat)
When -vv option is present, the setting is only applied to target objects with existing QoS
configuration. To limit the new settings to target objects with existing QoS configuration, it is useful
to specify -vv * in the command line.
QoS rules only manage host I/O. Use of this command to create new QoS rules requires a Quality
of Service license. Contact your local HP representative for information.
