Goal
The present document provides in detail the steps to shutdown/startup The CRS, OHAS, ASM & RDBMS Services on a RAC 11.2. Configuration:
Solution
1) Connect to node #1, then please check if the CRS/OHAS & services are enabled to autostart as follow (repeat this step on each node):
2) If not, then you can enable it as follow (repeat this step on each node):
3) Shutdown the services on each node as follow:
4) Verify the services were/are down (repeat this step on each node):
5) Then start the services on node #1 as follow (only on first node):
6) Wait 1 minute, then validate the services started & diskgroups were mounted (only on first node):
7) Then start the services on node #2 as follow:
8) Wait 1 minute, then validate the services started & diskgroups were mounted on node #2:
9) If there are more nodes in the RAC, then repeat the same steps (7-8).
10) Then check the status of the clusterware globally as follows:
# crsctl check cluster -all
Sample output:
**************************************************************
asmgrid1:
CRS-4537: Cluster Ready Services is online
CRS-4529: Cluster Synchronization Services is online
CRS-4533: Event Manager is online
**************************************************************
asmgrid2:
CRS-4537: Cluster Ready Services is online
CRS-4529: Cluster Synchronization Services is online
CRS-4533: Event Manager is online
**************************************************************

When attempting to shut down Oracle Clusterware, the Oracle Clusterware stack may report that it did not successfully stop on selected nodes (reference Bug 8651848). If the database home is on Oracle ACFS, then you may receive the following error:
CRS-5014: Agent orarootagent.bin timed out starting process acfsmount for action
This error can be ignored.
Alternatively, the Oracle Clusterware stack may report that it did not successfully stop on selected nodes due to the inability to shut down the Oracle ACFS resources. If this occurs, take the following steps:
-
Ensure that all file system activity to Oracle ACFS mount points is quiesced by shutting down programs or processes and retry the shutdown.
-
If the ora.registry.acfs resource check function times out, or the resource exhibits a state of UNKNOWN or INTERMEDIATE, then this may indicate an inability to access the Oracle Cluster Registry (OCR). The most common cause of this is a network failure. The commands "acfsutil registry" and "ocrcheck" may give you a better indicator of the specific error. Clear this error and attempt to stop Oracle Clusterware again.
Additional Steps Required When ACFS filesystem are involved:
You will need to perform the following additional steps instead:
A) Dismount all the ACFS filesystems running in the cluster as follows:
Where:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-d
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-n
If you do not specify this option, then the utility stops the volume resource on all active nodes in the cluster.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-f : This option stops the file system and also stops any databases or other resources that depend on this file system.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Example:
/dev/asm/volnew1-347 14680064 159700 14520364 2% /u01/app/grid/acfsmounts/acfsdgnew_volnew1
/dev/asm/vol_oh1-115 35651584 4590104 31061480 13% /u04acfs
$> srvctl stop filesystem -d /dev/asm/volnew1-347 -f
$> srvctl stop filesystem -d /dev/asm/vol_oh1-115 -f
B) Make sure the ACFS filesystem(s) was/were dismounted on all the nodes:
C) Then perform the steps described in the following document:
