crs_start

While Checking the status of database resources, ASM was shown as UNKNOWN on one node of a two node RAC.

$ crs_stat -t

Following error was coming while trying to start the +ASM2 instance with SRVCTL:

$srvctl start asm -n rac2

PRKS-1009 : Failed to start ASM instance "+ASM2" on node "rac2",
[CRS-0223: Resource 'ora.rac2.ASM2.asm' has placement error.]

While trying to start the same with crs_start :

$ crs_start -f ora.rac2.ASM2.asm

CRS-1028: Dependency analysis failed because of:
'Resource in UNKNOWN state: ora.rac2.ASM2.asm'
CRS-0223: Resource 'ora.rac2.ASM2.asm' has placement error

There are two ways to come out of this UNKNOWN state of resources:
1. Start the resource from sqlplus
2. Use crs_stop -f to clear the state of database resources.

$ export ORACLE_HOME=+ASM2
$ sqlplus "/ as sysdba"
SQL>startup 
Diskgroup mounted

It will go fine and the +ASM2 instnace will be started.

$ crs_stop -f ora.rac2.ASM2.asm

This will clear the UNKNOWN state and will make the resource as OFFLINE.

Now start the resource as:

$ srvctl start asm -n rac2

After using this check the status :

$ crs_stat -t

CRS-0215: Could not start resource 'ora.dev-101.LISTENER_DEV-101.lsnr'.

#crs_unregister ora.dev-101.LISTENER_DEV-101.lsnr
#crs_unregister ora.dev-102.LISTENER_DEV-102.lsnr

$netca /silent /responsefile $ORACLE_HOME/network/install/netca_typ.rsp /nodeinfo dev-101,dev-102
