FAST(DP) Implementation

My assumption is VMAX has disk groups, FAST control parameters, time window settings were preconfigured by enabling FAST controller if not do it so as follows:

symfast -sid 1234 enable -dp

Step: 1 View FAST license, optimizer window settings, status of optimizer and FAST

symlmf list -type emclm -sid 1234
symoptmz -sid 1234 show -parms
symoptmz -sid 1234 query
symfast list -state -sid 1234

Step: 2 View Disk Groups summary

symdisk list -dskgrp_summary

Step: 3 Create Tiers [static or dynamic]

symtier -sid 1234 create -name RAID1_EFD -tgt_raid1 -technology EFD -inc_type static -dsk_grp 1

symtier -sid 1234 create -name RAID1_FC -tgt_raid1 -technology FC -inc_type static -dsk_grp 2

symtier -sid 1234 create -name RAID6_SATA -tgt_raid6 -tgt_prot 6+2 -technology SATA -inc_type static -dsk_grp 3

List newly created tiers.

symtier list -sid 1234 -v

Step: 4 Create and view Policy

Total usage limits to be 300% for 3 tiers.

symfast -sid 1234 -fp create -name EFD_FC_SATA -tier_name RAID1_EFD -max_sg_percent 100
symfast -sid 1234 -fp -fp_name EFD_FC_SATA add -tier_name RAID1_FC -max_sg_percent 100
symfast -sid 1234 -fp -fp_name EFD_FC_SATA add -tier_name RAID6_SATA -max_sg_percent 100

View the newly created policy

symfast show -fp_name EFD_FC_SATA -sid 1234

Step: 5 Create and view Storage Group

A symmetrix device may only belong to one storage group under FAST control.

symsg create fastgroup -sid 1234
symsg -sg fastgroup add all devs -range A1:A7 -sid 1234
symsg show fastgroup -sid 1234

Step: 6 Associate storage group with FAST policy and view it

One or more storage groups can be associated with a FAST policy with priorities 1(high), 2(medium) or 3(low)

symfast -sid 1234 -fp_name EFD_FC_SATA associate -sg fastgroup -priority 1
symfast show -association -sg fastgroup

Step: 7 You can now view the history, audits at later point in time with the commands that were mentioned below!

View auto movement history of storage group

symfast list -history -sid 1234 -start_date 01312012:180000

View FAST history in Symmetrix audit log

symaudit list -sid 1234 -function_class FAST -start 03/01/2011:6:00:00
