Step Action

17 Change directory to the IORATE subdirectory and examine the script

student_devlst.csh. This script creates a file called devices_for_fast.ior # cd IORATE

# cat student_devlst.csh

#!/bin/csh

set SID=`symcfg list | grep Local | awk '{print $1}' | cut -c 10-12`

set CAP=`symdev list pd -sid 34 -N 2 | grep dev | grep -v ACLX | awk '{print $8}'`

set OF=devices_for_fast.ior

@ numdev=6

#

set devlst=`symdev list pd -N $numdev -cap $CAP | grep dev | awk '{print $2}'`

echo "#This file contains devices on which to write an IORATE pattern" > $OF

foreach i ($devlst)

echo Device = \"$i\" capacity 1000MB\; >> $OF

end

echo "These are the devices that will be written to by iorate"

cat $OF

18 Run the script student_devlst.csh. It creates devices_for_fast.ior and prints the contents of the file on the screen. Confirm that the listed devices match

the devices through recorded in step 11

Example:

# ./student_devlst.csh

These are the devices that will be written to by iorate

#This file contains devices on which to write an IORATE pattern

Device = "/dev/rdsk/emcpower86c" capacity 1000MB;








Step Action

19 Check the write patterns that are available for iorate to use

# cat patterns_for_fast.ior

#

# Pattern file for general drive I/O testing

#

# Note that any one pattern will do either read or write,

either random or

# sequential, of a given block size. To mix I/O types, a

given test will

# use a mix of I/O patterns. For details on the file

format, see the

# iorate(1) man page.

#

# WARNING:

# The write tests done with iorate are DESTRUCTIVE. Any

pattern that

# you define here that does writes will cause all of the

devices/files

# under test to be overwritten with pre-defined test data if

you are

# doing write testing. Only conduct write tests on

files/devices

# where the data is DISPOSABLE.

#

Pattern 1 = "2k Seq Read" io size 2KB sequential read;

Pattern 2 = "2k Random Read" io size 2KB random read;

Pattern 3 = "2k Seq Write" io size 2KB sequential write;

Pattern 4 = "2k Random Write" io size 2KB random write;



Pattern 7 = "8k Seq Write" io size 8KB sequential write;




Pattern 11 = "64k Seq Write" io size 64KB sequential

write;




Step Action

20 Examine the test file test_fast_wrt.ior # cat test_fast_wrt.ior

#IO test designed to run for 12 hours with 15 mins of idle time each hour

Test = "Mixed Pattern" for 45 min ignore 0 sec 50% Pattern 6, 50% Pattern

21 Examine the file iorate.cmd # cat iorate.cmd

iorate -f devices_for_fast.ior -t test_fast_wrt.ior -p

patterns_for_fast.ior

What this command does iorate is an I/O generator developed by EMC for all Unix platforms. It is periodically updated by EMC Performance Engineering and is available from the public ftp site: ftp://ftp.emc.com/pub/symm3000/iorate. The device file specifies the devices that will be exercised. The patterns specify the write patterns that are available. The test file specifies that pattern 8 (8K random writes) and pattern 6 (8K random reads) will be used on the specified devices. The I/O patterns will run all out for 45 minutes and slow down to 1 IO per second for 15 minutes. This combination will continue for 12 hours, which is why there are 24 lines in the test file. If you need more information on iorate read the iorate.man page in the same diredctory.

22 Start the I/O tests. Note that you must keep this terminal session running for

the rest of the day in order for the tests to continue.

# iorate.cmd

24 Start another terminal session on host1 and verify that I/O is being driven to

the devices by iorate

# symstat i 10 sid

Move to Lab Exercise 2. Come back to step 25 later



Step Action

25 Let at least an hour pass. After that time check the movement history from

the time class started. The times are based on the host time. If you are logged

into a host from a different time zone, make the appropriate adjustment

# symfast list history sid -start_date MMDDYYYY:hhmmss

Example using the time when the tests started in Step 23: # symfast list history sid 34 start_date 06102010:150321

Have any devices moved [Y/N] ____ If not wait a while and repeat the command If one or more devices have moved, is it one of your devices through [Y/N] ___ Do not be disappointed if your device has not moved. FAST works well over several days, not so predictably over a few hours. Also, there are relative differences between the hosts abilities to drive IO. A powerful host will see its devices move sooner than a slower host. Lastly, the FC/SATA cross tier algorithm is an algorithm that targets busy devices. So if host1 is driving a heavy IO load, its devices will get moved. If host 2 is driving a light IO load, its devices may not experience any moves even if it may be experiencing poor response times.

26 If one or more of your devices has moved, write down the device number(s)

Device number of first device that moved (e.g. B1) ____ More devices that may have moved ____ _____ ______ ______ _____ Using the editor, or using the echo command as shown below, create a file called Migrate.devs with a list of the moved devices. Example: # echo B4 > Migrate.devs

# echo B5 >> Migrate.devs

Sample contents of Migrate.devs B4

B5



Step Action

27 Check the storage group


Have the disks moved from RAID5_SATA to RAID1_FC [Y/N] ___ Based on the information gathered in step 11, which disk group does this tier occupy ____

28 Check the Symmetrix audit log for entries MM/DD/YYYY refers to todays date

# symaudit list sid -function_class FAST start MM/DD/YYYY

To view detailed information on one entry enter: # symaudit list sid -v n 1 record_num

29 Browse to the SMC Server and invoke SPA

From your desktop launch internet explorer and browse to http://:7071 Use the username and password provided in step 1



Step Action

30 Examine the performance snapshot of your storage group

1. Expand the Symmetrix Masking folder under your local Symmetrix 2. Expand the Storage Groups folder 3. Select Example

4. Expand each display by clicking on the magnifying glass. If you need help

understanding the statistics, consult the instructor 5. After you have finished, close down the SPA window by clicking the x in

the top right corner of the window.



Step Action

31 Stop the iorate process you started earlier. Using the file Migrate.devs move

the disks that were moved by FAST (see step 26) back to RAID5_SATA tier

which is in the disk group you identified in Step 11. Then delete the

Migrate.devs file

# symmigrate name -tgt_unconfig tgt_dsk_grp -tgt_raid5 tgt_prot 3+1 sid -f Migrate.devs est

Check on the status of migration periodically. Then terminate the migration after the status shows Migrated. # symmigrate name -sid query # symmigrate name -sid terminate # rm Migrate.devs

32 Delete the file devices_for_fast.ior from the IORATE subdirectory

# rm devices_for_fast.ior

Step Action

20 Check on the compliance of with the policy

1. Expand the Symmetrix Masking folder for the local array 2. Expand the Storage Groups folder 3. Select the storage group 4. In the Properties pane on the right youll see three tabs: General, Devices

and FAST Compliance 5. Select the FAST Compliance tab 6. The display should indicate that is in a Tier called

[OutOfPolicy] whereas the tier you created, should be empty.

Example



Step Action

21 Configure FAST Alerts

1. Click on the Tasks pane and select Enable/Disable Alerts 2. Check off User Approval required for Optimizer/FAST Config Change and

FAST Controller switched State if they are not already checked off Note that you will not see these alerts being triggered during class since the FAST controller has been set to work in Auto_approve mode. This exercise is to show you where the alerts can be set. There may be old alerts that may be visible in the Alerts list, if they have not been cleared.

22 Wait . at least an hour or longer. Check the compliance of the storage group with as in Step 20.

Did your storage group undergo a compliance move [Y/N] ____ Do not be disappointed if your devices do not move in the time available for class. FAST moves happen slowly. If there was a compliance move, right click the FAST folder under the local Symmetrix. Select FAST FAST Control Parameters Swap/Move History Enter a suitable time to filter out older moves. Have your devices moved [Y/N] _____ Example:

3 Check to see if the directory for SYMCLI executables is included in your

PATH variable and if not set, set it and export it # echo $PATH

Is the directory /usr/symcli/bin included in the PATH? _________

If not add /usr/symcli/bin to your PATH

For Unix C shell: set path = ($path /usr/symcli/bin)

For Unix Korn or Bourne shell: PATH=$PATH:/usr/symcli/bin export PATH


4 Note the Symmetrix device names and and physical device

names and of the first two regular devices (2-Way-Mir

only) that are accessible to this host. Exclude the ACLX device.

# symdev list pd sid -N 10

___________ ____________________________________ ___________ ____________________________________

Confirm that and make up the storage group defined in Lab 2 # symsg show -sid

Create a text file called Migrate.devs containing the names of the two devices: # echo > Migrate.devs

# echo >> Migrate.devs



Step Action

5 Confirm the Policy and Tier names associated with


The tier name should match from Lab Exercise 2 The policyname should match from Lab Exercise 2 Write down the Disk Group number to which the storage group belongs __ Example: DMX8HP2/> symfast show -association -sg hpFsg -sid 35

Step Action

6 Disassociate the storage group from the policy

# symfast sid -fp_name disassociate sg

Example # symfast -sid 35 -fp_name hp_policy disassociate -sg hpFsg

7 Disassociate the tier from the policy

# symfast sid -fp -fp_name remove tier_name

Example # symfast -sid 35 -fp -fp_name hp_policy remove -tier_name

hptier53

8 Delete the policy, tier and storage group

# symfast delete -fp -fp_name -sid

Example

# symfast delete -fp -fp_name hp_policy -sid 35

9 Delete the tier after removing the disk group

Identify the disk group associated with as you did in Lab 1 Step 11 # symtier show tier_name -sid # symtier remove tier_name -dsk_grp -sid

where DG# represents the disk group identified by the first command

# symtier delete -tier_name -sid

Example

# symtier remove -tier_name hptier53 -dsk_grp 1 -sid 35

# symtier delete -tier_name hptier53 -sid 35



Step Action

10 Delete the storage group

# symsg delete -force sid

11 Migrate the devices that used to be part of the storage group to RAID 1

protected devices using the device file Migrate.devs from step 4 and the disk

group number identified in step 5. In other words the devices stay in

the same disk group but they change RAID protection

# symmigrate name -tgt_unconfig tgt_dsk_grp -tgt_raid1 f Migrate.devs nop sid establish

Example # symmigrate name ss tgt_unconfig tgt_dsk_grp 1 tgt _raid1 f Migrate.devs nop sid 35 est

12 Check on the status of the migration periodically

# symmigrate name -sid query

13 Once the status shows Migrated, terminate the session

# symmigrate name -sid terminate

14 Delete the file Migrate.devs

# rm Migrate.devs
