netapp ontap UPGRADE

Affected: >= 9.16.1 and < 9.19.1

Fixed in: 9.19.1

Safe to downgrade to: a release before 9.16.1

1. Check installed version

apt-cache policy ontap || rpm -q ontap || ontap --version

2. UPGRADE to 9.19.1 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade ontap

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade ontap

Note

Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.

3. If no update is available yet, DOWNGRADE to a release before 9.16.1 (Debian / Ubuntu)

apt-cache madison ontap sudo apt install ontap=<VERSION_BEFORE_9.16.1> sudo apt-mark hold ontap

3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list ontap sudo dnf downgrade ontap-<VERSION_BEFORE_9.16.1> sudo dnf versionlock add ontap

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.
