Steps To Shutdown/Startup The Exadata & RDBMS Services and Cell/Compute Nodes On An Exadata Configuration. [ID 1093890.1]
The note is describing a graceful power down and manual power up of Exadata.
But how about an unplanned power outage?
Would there be any reason for Exadata not to startup automatically after power is restored?
Can you give some more information on what didn't start up? Did all of the servers power on? Did CRS not start on some nodes? In my experience, components all power back on after an unplanned power outage.1 person found this helpful
Can you give some more information on what didn't start up?The 4 db nodes didn't boot up on this half rack Exadata but the 7 cells did.
Support pointed me to 1470536.1 about the issue.
It could be in firmware (Active image version: 188.8.131.52.0.120304) or ACS changed the standards for the policy in the ILOM.
I have a second half rack (Active image version: 184.108.40.206.2.111221) which is configured to do a full autoboot (eg HOST_LAST_POWER_STATE = enabled) after a power outage. For now I have changed the ILOM setting to enabled and I will wait for a final answer from support.
I got it confirmed, the standard should be to enable the "HOST_LAST_POWER_STATE" setting on all components.
From different sources I have information some machines are configured not to auto boot the db nodes and some are configured as the standard.
This setting will definitely be on my post ACS check list from now on.
