for best storage efficiency and volume-level performance

– 20-drive RAID-DP groups adds to storage efficiency

– Flash Cache support improves performance for repeat

random reads

#1 – Large Datastores

#2 – New FAS or V-Series Systems

Customers buying or upgrading to FAS or V 6200 and

3200 systems

– FAS/V 6200 are only supported on Data ONTAP 8.0.1

– FAS/V 3200 are introduced first on Data ONTAP 8.0.1



Data ONTAP 8.0.1 7-Mode Use Cases

Performance-insensitive primary and secondary

storage where data compression can improve storage

efficiency – Data Compression

#3 – Compressible Datasets

#4 – FC and iSCSI SAN Storage

SAN deployments where non-disruptive data

movement is important – NetApp DataMotion

FCoE or Unified Target Adapter

#5 – New Datacenter Deployments

Customers planning new datacenter deployments may

want to consider an unified 10GbE network - UTA



Preparing for an upgrade



Choosing the version of Data ONTAP

Does the customer have a preference?

Some customers are only authorized to install

releases they have already validated.

What hardware components are installed?

New components, like Flash Cache or UTA cards,

often function better with the latest RC or P releases.

What functionality does the customer want?

New functionality may only be available in new

releases.



Choosing an RC or P release

1. RC releases have been tested internally but have not

reached the minimum number of installs on production

systems to be granted GA status. They are production

ready and supported by NetApp Global Services (NGS).

2. P releases contain patches added to RC or GA releases.

They may not have been as rigorously tested. NetApp

recommends P releases if a system has already

experienced a bug. These upgrades are free for

Premium Support customers. Troubleshooting P

releases can be more time-intensive for NGS.

When installing a P release, we suggest offering a free

upgrade to the next GA release. Make the offer time-limited

(e.g., within 2 weeks of GA availability).



Determine Feasibility and Potential

Issues

Compare current version with new version by reading the

Release Notes

Read the Upgrade Guide – it contains caveats for Non-

Disruptive Upgrades.

Verify free space in aggregates (<=96% full)

Verify free space in volumes with LUNs (>= 1MiB)

Run the HA Configuration Checker

(aka Cluster Configuration Checker)



Determine Feasibility and Potential

Issues

Identify SnapMirror/SnapVault source and destination

systems and record relationship information

Run the Upgrade Advisor tool – check for firmware

upgrades and include back out plans

SAN environments – verify components are still compatible

using the Interoperability Matrix Tool (IMT)

- verify all hosts are multipathed and the multipath

connections are working

Use the Knowledge Base, Communities, and TechNet

websites to search for tribal knowledge



Create a checklist

Checklists reduce errors and gives the customer confidence

in the process. Add these steps to your checklist:

- use the config dump command to backup the current

configuration

- Take Snapshots of the root volume and all

SnapMirror/SnapVault volumes

(create a „source‟ script to automate the work)

- Use the logger command to insert comments into the

system log

- Capture the options settings to a text file before and

after the upgrade



Verifying storage controller options using WinMerge to

compare text files



Prepare for the worst

- establish checkpoints and hard stop conditions

Set Customer Expectations

- NDU or disruptive upgrade?

Major release upgrades should always be disruptive

- Time required to perform upgrade and reversion

Plan for 20 – 60 minutes just for the download process

- Impact of reversion



13

Check to see if the card has been properly updated.

filer01> version -b

The primary kernel should be 6.4.5.

13.5

If step 13 fails, perform the following steps and repeat step 12:

filer01> priv set advanced

ljcds-filer*> bootfs help info

ljcds-filer*> bootfs fdisk <name> 1

14Terminate CIFS.

filer01> cifs terminate

15Disable the cluster.

filer01> cf disable

16Stop the iSCSI service:

iler01> iscsi stop

17Halt the filer.

filer01> halt

GO/NO-GO CHECKPOINT

18Restart the filer

CFE>bye

19Interrupt the reboot process. While POST is running, press CTRL-

BACKSPACE to abort the autoboot.

20Update the MB firmware

CFE>update_flash

21Reset the firmware.

CFE>set-defaults



Performing the upgrade

20© 2008 NetApp. All rights reserved. Limited Distribution


Performing the Upgrade

Perform intermediate upgrades from 7.2 and earlier to

7.3 first.

Download the correct install package

- one for upgrading from 7.3.x

- one for upgrading from 8.x

Resize root volume (250 GiB minimum)

Halt or abort SnapMirror, SnapVault and Dedupe

processes

Verify system configuration and cf functionality by

rebooting or performing a takeover/giveback



Performing the Upgrade

Upgrade using the software update command

- CIFS and NFS installs not supported (file copy still

acceptable)

Use HTTP server to transfer install package and

firmware

- easy to install a free standalone server on laptop

- eliminates need to connect to customer network

Install firmware packages that were released after the

latest GA version of Data ONTAP



Known Upgrade Issues

23© 2008 NetApp. All rights reserved. 23Limited Distribution


Upgrade Issues

New console messages to become familiar with

SnapLock remains unsupported until Data ONTAP 8.1

32-bit to 64-bit aggregate conversion still requires data

migration

- root volume can now be moved to 64-bit aggregate

SnapMirror/SnapVault restart checkpoints deleted during

upgrade

- The replication sessions will restart at the beginning



Upgrade Issues

NTP only supported time protocol

- rtc and rdate no longer supported

Dedupe volume limitations

- 100 or fewer dedupe volumes for NDU

(you must „rehydrate‟ excess volumes)

- DOT 8.0.1 will support 300 volumes for future NDUs

Manual editing of /etc/rc required

- process does not change „vif‟ to „ifgrp‟



Upgrade Issues

System firmware updates will add 5 – 10 minutes and

trigger a reboot

NVRAM firmware updates add 10 minutes to process

Flash Cache (PAM II) firmware upgrades

- During NDU, a node may reboot several times as the

firmware is updated prior to booting ONTAP

FAS/V3200 series may start flashing Fault LEDs

- see TSB 1101-02: Fault LED Flashing on FAS/V3200

for remediation process



Reversion Process



The Reversion Rules

Contact NetApp Technical Support first

- reversions have unique requirements

- the process is purposely not well-documented for yours

and the customer‟s protection

- newly installed systems without data and test systems are

only exceptions

Scenarios requiring NGS assistance:

- ONTAP upgrade process failed and did not finish

- ONTAP upgrade finished, but system is unusable

- System performance or behavior is noticeably worse



Reversion Concerns

Inode-to-Path (I2P) must complete before revertingfas> priv set advanced

fas> wafl scan status

Cannot revert with 64-bit aggregates

- must migrate data to 32-bit aggregates

Cannot revert to release prior to DOT 7.3

Delete all 8.x snapshots to revert to 7.3 or earlier

- this is why you took Snapshots of root vol and

SnapMirror/SnapVault volumes prior to the upgrade



Reversion Concerns

NFS volumes may need to be remounted

- File System Identifiers (FSIDs) are rewritten during the

reversion

Disable quotas or allow the quota upgrade process to

complete

- use quota status command to check

Edit /etc/rc to change ifgrp back to vif

Solid State Disk shelves must be removed

- only supported in DOT 8.0.1

- must migrate data, destroy aggregates, and remove shelf



Reversion Concerns

MultiStore vfilers must be online but all services turned

off

- The vfilers also get reverted. Turning them off can corrupt

them and make them unusable.

Deduplicated volumes must first have their metafiles

reverted.

- You will be instructed on how to use the sis revert_tocommand



Post Upgrade Steps



Post Upgrade

Test client access for every licensed protocol

– failure is often due to changes in ONTAP options

– Make the customer perform the testing

Test cluster failover functionality

- be certain you can prove failover worked when you left

If you experience something not documented then add

what you have learned to the tribal knowledge
