1. Create an AO configuration using the createaocfg command. Example: cli% createaocfg -t0cpg tier0_R1_SSD -t1cpg tier1_R6_FC -t2cpg tier2_R6_NL -mode Performance AOCFG_name where: • -t0cpg is the tier 0 CPG. • tier0_R1_SSD is the tier 0 CPG name. • -t1cpg is the tier 1 CPG. • tier1_R6_FC is the tier 1 CPG name. • -t2cpg is the tier 2 CPG. • tier2_R6_NL is the tier 2 CPG name. • -mode specifies one of the following optimization biases for the AO configuration: ◦ Performance: Move more regions towards higher performance tier. ◦ Balanced: Balance between higher performance and lower cost. ◦ Cost: Move more regions towards lower cost tier. • AOCFG_name is the name of the AO configuration (up to 31 characters in length). NOTE: Tiers must be defined in "speed" order-tier 0 must be the fastest tier (SSD), tier 2 the slowest (NL). AO makes the assumption internally that tiers are defined in this speed order. 2. Set CPG warning limits to limit the size of tier 0 and tier 1, leaving tier 2 unlimited. In the following example, the tier 0 limits are set to 64 g and the tier 1 limits to 256 g, respectively: cli% setcpg -sdgw 64g t0cpgname cli% cli% setcpg -sdgw 256g t1cpgname 3. Create a schedule to run startao on the AO configuration periodically. In the following example, the AO configuration is set to run every day at 7:15 pm from Monday through Friday. The scheduled startao command considers 12 hours of statistics for its region moves. The 12 hours of statistics are from 7:15 am until 7:15 pm, as the -etsecs parameter was not specified. cli% createsched "startao -btsecs -12h AOCFG_name" "15 19 * * 1-5" run_AOCFG_name You can take advantage of several features that are not available in the external System Reporter by using the following options: Table 15 Additional Options Not Available in an External System Reporter Option -maxrunh 6 Description Instructs the startao to ensure that the command completes in 6 hours, limiting the number of region moves if necessary.
