Building FAST with CLI

Check Licenses
Check disk groups for drive configuration – can rename
EFD, FC, SATA

There are multiple FAST settings and parameters that affect the behavior of the FAST controller. These include:
Operating Mode
Maximum Moves Per Day
Maximum Simultaneous Moves
Workload Analysis Period
Initial Analysis Period
Move Type
Use Host Invisible Devices
Performance Time Window
Device Movement Time Window

Do this with FAST setting
Creating a static Symmetrix tier
The Symmetrix tier name
The desired protection type of the tier
The disk technology to be used for the tier
The physical disk group numbers/names to be added to the tier

Grooup#_FC_raid_speed or The Symmetrix tier name was chosen to indicate the RAID protection type (RAID 1), drive size (450 GB), and drive type (FC)—R1_450GB_FC.

Creating a Symmetrix FAST policy
A FAST policy defines the upper usage limits for up to three tiers for any storage groups associated with the policy.
When creating a FAST policy, the following information must be known:
The FAST policy name
Up to three Symmetrix tiers to be used in the policy
The upper usage limits for each of the Symmetrix tiers being added

Creating a Symmetrix storage group
A storage group logically combines Symmetrix devices to be managed together. When creating a storage group for FAST, the following information must be known:
The storage group name
The standard provisioning devices to be added to the group

symdisk -sid 238 list -dskgrp_summary
Find potential Devices
(notice that the tech type, EFD, FC or SATA was identified in previous cmd)
C:> symdev -sid 238 list -disk_group 2
List existing tiers (required to build ‘-fp’ s (fast policy))
C:> symtier -sid 238 list
Symmetrix ID : 000194900238
No matching Symmetrix Tier found
To create a tier CLI (GUI is also possible)
C:> symtier -sid 238 create -name EFD_Raid31 -tgt_raid5 -tgt_prot 3+1 -technology EFD -inc_type static
-dsk_group 2
C:> symtier -sid 238 list
symtier -sid 238 list
List existing storage groups
C:> symsg -sid 238 list
Create Storage Group via CLI
(depending on deployment, can great multiple storage groups per drive type,
or create a storage group for the host and add devs from desired storage types)
NOTE: This is probably more easily done from the GUI
C:> symsg -sid 238 create
Add devices to the Storage Group
(for the demo, select 2 devices from each Technology Disk Group)
C:> symsg -sid 238 -sg SGby52Test1 addall devs -range 098:099
(this added two EFD devs)

C:> symsg -sid 238 -sg SGby52Test1 addall devs -range 09b:09c
(this added two SATA devs)
C:> symsg -sid 238 -sg SGby52Test1 addall devs -range 0a0:0a1
(this added two FC devs)
C:> symsg -sid 238 show SGby52Test1
To see current state of the FAST Engine:
C:> symfast -sid 238 list -state
Symmetrix ID: 000194900238
Fast State : Enabled
Reason: : N/A

Current Activities : Idle

Enable / Disable FAST Engine
C:>symfast -sid 238 disable
Execute DISABLE operation for FAST (y/[n]) ? y
The FAST DISABLE operation finished successfully
C:>symfast -sid 238 enable
Execute ENABLE operation for FAST (y/[n]) ? y

The FAST ENABLE operation finished successfully

Performance collection and Data Movement Time Windows
C:> symoptmz -sid 238 show -parms
NOTE: To adjust these parms, a .txt file with the desired parms is
needed. Examples will be provided in Appendix

============================================
Examine FAST Engine parms
C:> symfast -sid 238 list -control_parms
Symmetrix ID: 000194900238
Data Movement Mode : User_Approve
Min Initial Workload Period(hrs) : 1
Workload Analysis Period(hrs) : 2
Max Simultaneous Device Moves : 8
Max Device Moves Per Day : 200
Swap Not Visible Devices : Disabled

Allow Only Swap : Disabled

To update the FAST Engine Parms
—> symfast -sid set -control_parms
( can be found for desired parm with “symfast -h | more”)
C:> symfast -sid 238 set -control_parms -mode auto_approve
C:> symfast -sid 238 list -fp
Symmetrix ID : 000194900238
No matching FAST policy found
C:>symfast -sid 238 -fp create -name Test1
C:> symfast -sid 238 list -fp

Symmetrix ID : 000194900238

Policy Name Tiers Assocs

Test1 0 0

Next, apply the Tiers

C:>symfast -sid 238 -fp -fp_name Test1 add -tier_name EFD_Raid31 -max_sg_percent 50
C:>symfast -sid 238 -fp -fp_name Test1 add -tier_name FC_Raid6 -max_sg_percent 5
C:>symfast -sid 238 -fp -fp_name Test1 add -tier_name SATA_Raid1 -max_sg_percent 100
C:> symfast -sid 238 show -fp_name Test1
C:> symfast -sid 238 -fp_name Test1 associate -sg SGby52Test1 -priority 1
C:> symfast -sid 238 show -fp_name Test1
C:> symfast -sid 238 list -association -demand -sg SGby52Test1
C:> symcfg discover
C:\ >symfast -sid 238 list -plan
It will take about anywhere from 20 minutes to an hour before the plan to migrate appears but when it’s ready…
C:\ >symfast -sid 238 list -plan
C:> symfast -sid 238 -plan approve -id 01132010:094531
