Oracle RAC on OVM & Netapp 8.1.2 7Mode

PNAGASUBRAMANYA — Thu, 05 Jun 2025 05:31:18 GMT

Does anyone have this combination setup. i cannot see a support on the IMT

We have this combination setup. The VM's are rebooting due to node eviction issue caused by missing heartbeat to disk (LUN from NetApp) for POOL FS

The heartbeat and other timeout values are setup based on NetApp Best Practices

Thank you

Thank you Karthik,

The issue did not re-occur after the below settings mentioned in the TR. However we are not sure if OVM clustering with FC disks is supported? in IMT it is not

Update /etc/sysconfig/o2cb with the following

O2CB_HEARTBEAT_THRESHOLD=96

O2CB_RECONNECT_DELAY_MS=4000

O2CB_KEEPALIVE_DELAY_MS=4000

O2CB_BOOTCLUSTER=34a289117ee06652

O2CB_IDLE_TIMEOUT_MS=190000

O2CB_ENABLED=true

O2CB_STACK=o2cb

You welcome.

Yes, it's supported with IMT. I just checked. Please send me a mail to nkarthik@netapp.com, if you want the IMT pdf file.
