All,

I have a 2-node RAC on HP hardware, Linux 4 and Clarion CX500 SAN with Oracle 10g R1 (10.1.0.4.0).

It was working fine till now, and all of a sudden, the node applications seem to have a problem.
I get the following error when I run srvctl:

$srvctl status nodeapps -n
VIP is running on node:
GSD is running on node:
Listener is running on node:
ONS daemon is not running on node:

Iam not sure how ONS did not start.
I rebooted the servers after graceful shutdowns and still the same status!

I did use crs_stat utility also just to double-check with the same result.

Iam at a loss now on how this could happen... Nothing was changed since I installed the RAC and it was working fine till now.

Any help in this matter will be highly helpful and I would be much obliged.

Thanks in advance!

Suhas
