NetApp step by step process of Data ONTAP 7.3.1 to 7.3.2 upgrade method for active/ active Configuration


Overview
This document explains the step by step process of Data ONTAP 7.3.1 to 7.3.2 upgrade method for active/ active Configuration.
  • This non-disruptive active/active upgrade procedure ensures high storage system availability
  • This process is very important in the present environment where we don’t have any downtime available.
1.2 Purpose
  • This document explains the step by step process of Data ONTAP 7.3.1 to 7.3.2 upgrade method for active/ active Configuration.
  • This non-disruptive active/active upgrade procedure ensures high storage system availability. 
2. PROCEDURE    
2.1               PREREQUISITE 
1. Check if the FAS series supports the DATA ONTAP version.

2. Use Upgrade Advisor to understand the requirements for the upgrade and to generate an
    upgrade plan.

3. Check compatibility in the NetApp Interoperability Matrix (IMT) tool.

4. If SnapMirror is being used, check the Data ONTAP version on destination storage system. The
    destination storage system should have the same or higher version of DATA ONTAP.

5. Check the system firmware
     >sysconfig –a
     > Version -b
Refer this link for more information:

6. Check the disk firmware
     >Sysconfig -A
     >rdfile /etc/disk_fw/
Refer this link for more information:
                     http://support.netapp.com/NOW/download/tools/diskfw/

7. Check the disk shelves’ firmware 
     > /etc/shelf_fw /
     >Sysconfig -v
Refer this link for more information:
                   http://support.netapp.com/NOW/download/tools/diskshelf/

8. Check if the volumes have at least 1 MB of free space to accommodate the changes.

9. Check for any failed disk and replace them before the activity.

10. Make sure you have connectivity to RLM/BMC/direct serial connection while planning the activity.

11. If you use de-duplication technology, ensure that your system includes no more than 100 deduplicated
volumes and that no de-duplication operations are active during the Data ONTAP
Upgrade.

12. Make sure that there is no SnapMirror sessions running/active or scheduled to run during the
activity.

13. To disable automatic giveback for activity in active/active (if enabled)
     > options cf.giveback.auto.enableoffcedure to Upgrade ONTAP 7.3.1 to 7.3.2 
2.1 ProEnsure that you have checked the following before you perform the upgrade:
 
 Step 1: Make a back up /etc/rc and /etc/hosts
Backup /etc/rc and /etc/hosts files on both nodes.
Capture output of fcadmin config command. 

Step 2: Software Download

  • Select the Data ONTAP 7.3.2 and Download it desktop or laptop
  • If you don’t find the Specific version 7.3.2 in the list of software’s.
  • In the below software list we have options to Select To access a specific software

Step 3: Copy Software onto the filer
  • Get access to share vol0 in cifs.
  • Open the share in windows and copy the Data ONTAP 7.3.2.exe in /etc/software directory.
  • Unzip the software file in the share.
Step 4: Install 7.3.2 system file on both the filers.
Filer1> software install 732_setup_q.exe
Filer2> software install 732_setup_q.exe
Step 5: Run download command.
Filer1> download
Filer2> download 
Step 6: Verify primary kernel is at 7.3.2
Filer1> version -b
Filer2> version -b  
  • Once download is completed you need to reboot the filers to use the new ONTAP.
  • But as we are in active / active configuration and performing non disruptive,   
Step 7: Takeover Process by Filer 1
From filer1, enter the following commands:

 Filer1>cf takeover
  • Now filer2 goes reboot.
  • While booting press Ctrl+c to LOADER prompt and update the motherboard firmware.
 LOADER>update_flash
LOADER> bye
Step 8: Giveback Process 
Filer1> Partner
filer1\filer2>cifs terminate -t nn
  • while upgrade we need downtime for cifs only 
  • nn is a notification period in minutes for your clients
Step 9: Giveback to Filer 2
Filer 1\ Filer 2>ndmpdkillall
Filer 1\ Filer 2> partner
Filer 1>cf giveback
After giveback is completed, verify Filer 2 is at ONTAP 7.3.2
Step 10: Complete maintenance checklist on Filer 2
  • Maintenance Checklist
  • Verify all Aggregates online
Filer 2> aggr status

Verify all volumes online

Filer 2> vol status
  • Verify CIFS is operational
Filer 2>cifsdomaininfo

Filer 2>cifs sessions –t

Filer 2>cifs stat
Follow the same to upgrade filer1 from STEP:7
