Relocate Voting disk to +DATA1 to different disks

Step1: Verify voting disk location using below command 

[root@rac1 bin]#
[root@rac1 bin]#
[root@rac1 bin]# ./crsctl   query css votedisk
##  STATE    File Universal Id                File Name Disk group
--  -----    -----------------                --------- ---------
 1. ONLINE   10ee09a0a8a44fe5bf6184e1f3abdc06 (ORCL:DISK1) [DATA1]
Located 1 voting disk(s).
[root@rac1 bin]#
[root@rac1 bin]#


Step2:-  Now move voting disk  to +DATA2 using below command 

[root@rac1 bin]# ./crsctl  replace votedisk +DATA2
Successful addition of voting disk 2edb42aeb93d4fa7bfd06327ae391776.
Successful deletion of voting disk 10ee09a0a8a44fe5bf6184e1f3abdc06.
Successfully replaced voting disk group with +DATA2.
CRS-4266: Voting file(s) successfully replaced
[root@rac1 bin]#
[root@rac1 bin]#

Step3:- verify voting disk location

[root@rac1 bin]# ./crsctl   query css votedisk
##  STATE    File Universal Id                File Name Disk group
--  -----    -----------------                --------- ---------
 1. ONLINE   2edb42aeb93d4fa7bfd06327ae391776 (ORCL:DISK2) [DATA2]
Located 1 voting disk(s).
[root@rac1 bin]#


Note : make sure asm_diskstring configure properly  before relocation

Relocate OCR from +DATA1 to different disks

Task:-
 Relocate OCR from +DATA1 to +DATA2

Requirement:-

Need +DATA2 disk group 


Step 1: Check current OCR location 


[root@rac1 bin]# ./ocrcheck

         Cluster registry integrity check succeeded

         Logical corruption check succeeded

Step 2: Verify asm diskgroup for relocate 

[root@rac1 bin]# oracleasm listdisks
DISK1
DISK2
DISK3

Step 3:-  Now add +DATA2 as new OCR location and verify using below command  
[root@rac1 bin]#
[root@rac1 bin]# ./ocrconfig -add +DATA2
[root@rac1 bin]#
[root@rac1 bin]#
[root@rac1 bin]# ./ocrcheck
Status of Oracle Cluster Registry is as follows :

         Device/File Name         :     +DATA1
                                    Device/File integrity check succeeded
         Device/File Name         :     +DATA2
                                    Device/File integrity check succeeded

                                    Device/File not configured

                                    Device/File not configured

                                    Device/File not configured

         Cluster registry integrity check succeeded

         Logical corruption check succeeded

Step4:- Now delete old location +DATA1 using below command  and verify

[root@rac1 bin]# ./ocrconfig -delete +DATA1
[root@rac1 bin]#
[root@rac1 bin]#
[root@rac1 bin]# ./ocrcheck
Status of Oracle Cluster Registry is as follows :

         ID                       :  918475055
         Device/File Name         :     +DATA2
                                    Device/File integrity check succeeded

                                    Device/File not configured

                                    Device/File not configured

                                    Device/File not configured

                                    Device/File not configured

         Cluster registry integrity check succeeded

         Logical corruption check succeeded

ORA-00845: MEMORY_TARGET not supported on this system

Cause:

Memory Target  error come due to lack of tmp space on server .

Solution :

Need to increase temp space on server

# umount tmpfs
