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
