Isilon OneFS upgrade to 7.2.1.0






It's the time.. Time to UPGRADE

I recently performed a OneFS upgrade to 7.2.1. The entire process is categorized in three phase and below are the steps:

Pre-upgrade tasks:


Use the below commands and do the overall health check of the cluster

• isi status -D
•  isi_for_array -s 'isi devices | grep -v HEALTHY'
•  isi_for_array -s 'gmirror status'
•  In the OneFS web administration interface, click Dashboard > Cluster Overview > Cluster Status.In the Status area, click the ID of a node.In the Chassis and drive status area, click Platform
•  isi_for_array -s 'df -h'  - Check the utilization of all file system and confirm that it is below 90%
•  isi events list

Back up data.
• Backup all important data like corn jobs, etc.
• Ensure synciq jobs completed sucessfully

Collect cluster status.
isi status -D -w

Complete system jobs.
• isi services -a isi_job_d disable

Pause or cancel SyncIQ jobs.
• isi sync policy list -v
• isi sync jobs list"
• isi sync jobs pause --all

Cancel all running jobs:  
Use command (isi job jobs list) to view any running jobs, use command ( isi job jobs cancel JobIDNumber) to cancel by ID number

Implementation plan

Check the upgrade image:


# isi update --check-only
when asked to specify  the image to update then provide the path where the OneFS image is stored.

Check if you have any job running

# isi job jobs list

Flush the cache 

# isi_for_array isi_flush

Perform the upgrade

# isi update

when asked to specify  the image to update then provide the path where the OneFS image is stored.

Are you sure you wish to upgrade (yes/no)? yes

Reboot to complete the process? (Yes/No) Yes

Now system run the upgrade process and you may need to reconnect to the cluster

Check the version

# isi version

Check the events

# isi event list -w

Install the patch if required/needed

Change to the directory where the patch image is stored

# cd <path>

# isi pkg install <file name>

Some times few drives may need firmware upgarde, run below command to do the same

# isi_disk_firmware_reboot -p

Check the services and enable if you have disabled it before performing the upgrade

# isi services -a supportiq enable
# isi services -a nfs enable
# isi services -a smb enable

Cancel all the events

#isi events cancel all

Gather the info and gave it to EMC for review

# isi_gather_info


Happy Learning!
