While installing Oracle 12c GI software...getting error

Verify that the cluster services are started properly on both nodes.

bash-4.1$ ./srvctl status nodeapps
VIP rac01-vip.localhost is enabled
VIP rac01-vip.localhost is running on node: rac01
VIP rac02-vip.localhost is enabled
VIP rac02-vip.localhost is running on node: rac02
Network is enabled
Network is running on node: rac01
Network is running on node: rac02
ONS is enabled

bash-4.1$

This concludes the 12c Grid infrastructure installation. Next step is an installation of database software and creating RAC database.

Oracleasm deletedisk diskname failed

[root@rac01 init.d]# oracleasm deletedisk ASMD1
Clearing disk header: failed
Unable to clear disk "ASMD1"
[root@rac01 init.d]# oracleasm deletedisk ASMD2
Clearing disk header: failed
Unable to clear disk "ASMD2"
[root@rac01 init.d]# oracleasm deletedisk ASMD2
Clearing disk header: failed
Unable to clear disk "ASMD2"

Solution Description

The issue is the disk header cannot be overwritten by the oracleasm command which is written by the previous commands. For this, you have to manually overwrite the header information by the OSdd command.

Step 1: find out the device information using blkid command.

[

[root@rac01 init.d]#
[root@rac01 init.d]# blkid | grep oracleasm
/dev/sdb1: LABEL="ASMD1" TYPE="oracleasm"
/dev/sdc1: LABEL="ASMD2" TYPE="oracleasm"
/dev/sdd1: LABEL="ASMD3" TYPE="oracleasm"
[root@rac01 init.d]#

Step 2: overwrite the header with null value using dd command. Or we can say clear the device header manually

[root@rac01 init.d]# dd if=dev/zero of=/dev/sdc1 bs=1024 count=100

100+0 records in

100+0 records out

102400 bytes (102 kB) copied, 0.0161951 s, 6.3 MB/s

[root@rac01 init.d]# dd if=dev/zero of=/dev/sdd1 bs=1024 count=100

[root@rac01 init.d]# dd if=dev/zero of=/dev/sdb1 bs=1024 count=100

Step 3: Sync the disk and delete the disk using oracleasm command

[dev]# /sbin/partprobe /dev/sdb1

[dev]# oracleasm deletedisk OCR_VOTE                           Disk "OCR_VOTE" defines an unmarked device

[root@rac01 init.d]# 

[root@rac01 init.d]# /etc/init.d/oracleasm deletedisk ASMD1

[root@rac01 init.d]# /etc/init.d/oracleasm deletedisk ASMD2

[root@rac01 init.d]# /etc/init.d/oracleasm deletedisk ASMD3

I checked the asm log

# cat /var/log/oracleasm

Unable to open device "/dev/sdb1": Device ot resource busy....

But when I create new ASM disk getting an error....so I restarted the virtual machine then ASM creation issue was resolved.

[root@localhost Desktop]# /etc/init.d/oracleasm createdisk Disk1 /dev/sda6

Marking disk "VOL1" as an ASM disk: [FAILED]

2017/11/05 16:06:32 CLSRSC-258: Failed to configure and start ASM

Died at /ora/oracle/app/grid/crs/install/crsinstall.pm line 1976.

Solution:

# export LD_BIND_NOW=1

Then I run root.sh script in each node...It was successfully done.

INS-40927 Interfaces with common subnets that have different names

Question:  How do I fix the INS-40927 error? I am getting the "INS-40927: Interfaces with common subnets have different names on different nodes." error when trying to install Oracle 11g r2 Grid control:

 

Answer: The oerr utility says this for the INS-40927 error:

INS-40927: Interfaces with common subnets have different names on different nodes.
Cause: The following nodes have interfaces in common subnets that have different interface names: string
Action: Ensure that the names of interfaces defined on common subnets are the same on all cluster member nodes

All interfaces have to use the same name. The interface (e.g. a public LAN), must have the same name on all nodes, same naming ruke for the interconnect. 

Solution:

First of all, stop all virtual machines. Goto virtual machine setting and remove network cards and add one by one in each virtual machine and startup machines.

PRVF-5410 check of common NTP Time Server failed

Do it on all cluster nodes

Either configure NTP, or make sure it is not configured so the Oracle Cluster Time Synchronization Service (ctssd) can synchronize the times of the RAC nodes. In this case we will deconfigure NTP.
