11gR2 RAC 独占模式replace votedisk遭遇PROC-26，restore ocr遭遇CRS-4000、PROT-35
原文链接：http://blog.itpub.net/23135684/viewspace-748816/
11gR2 RAC系统的存储数据全然丢失，全部节点的软件都安装在本地磁盘中。本地磁盘保留了OCR的备份，以下讨论通过replace
votedisk和restore ocr的方式恢复Clusterware的正常执行：
依据上面创建的磁盘组，运行下面的replace votedisk和restore ocr操作，收到例如以下报错：
[root@rac1 bin]#./crsctl replace votedisk +OCR
[root@rac1 bin]#./ocrconfig -restore /u01/app/grid/11.2.0/cdata/backup00.ocr
注意以上加红加粗两点。votedisk和ocr就能够得到顺利的恢复。
完毕以上操作之后，asm spfile并没有被创建。
[root@rac2 bin]# ./crsctl stop has -f
CRS-4133: Oracle High Availability Services has been stopped.
运行下面的步骤手动创建ASM SPFILE文件：
1).创建ASM PFILE文件：
2).创建SPFILE文件：
3).重新启动HAS服务，验证SPFILE參数：
SPFILE被成功配置。

Applies to:
Oracle Server - Enterprise Edition - Version: 11.2.0.1 to 11.2.0.2 [Release: 11.2 to 11.2]
Microsoft Windows (32-bit)
Microsoft Windows x64 (64-bit)
Goal
The goal of this document is to provide the steps necessary to restore the OCR after the 1st ASM diskgroup, which contains the OCR, Voting Disks, and ASM SPFILE is lost.
The general process of restoring the OCR from backup is documented here: Restoring
Oracle Cluster Repository.
Solution
When using an ASM disk group for CRS there are typically 3 different types of files located in the disk group that potentially need to be restored/recreated:
- The Oracle Cluster Registry file (OCR)
- The Voting file(s)
- The shared SPFILE for the ASM instance(s)
1. Locate the latest automatic OCR backup
When using a non-shared CRS home, automatic OCR backups can be located on any node of the cluster, consequently all nodes need to be checked for the most recent backup:
PROT-26: Oracle Cluster Registry backup locations were retrieved from a local copy
RACNODE01 2010/08/20 12:25:00 C:\app\11.2.0\grid\cdata\cluster_name\backup00.ocr
RACNODE01 2010/08/20 08:24:58 C:\app\11.2.0\grid\cdata\cluster_name\backup01.ocr
RACNODE01 2010/08/20 04:24:55 C:\app\11.2.0\grid\cdata\cluster_name\backup02.ocr
RACNODE01 2010/08/19 04:24:41 C:\app\11.2.0\grid\cdata\cluster_name\day.ocr
RACNODE01 2010/08/09 04:22:07 C:\app\11.2.0\grid\cdata\cluster_name\week.ocr
2. Clear the partitions of the disks that were used in the 1st diskgroup:
/q \\.\ORCLDISKOCRVOTE0
$CRS_HOME\bin\logpartformat /q \\.\ORCLDISKOCRVOTE1
$CRS_HOME\bin\logpartformat /q \\.\ORCLDISKOCRVOTE2
3. Re-Stamp the 1st diskgroup's (+OCRVOTE) disks using ASMTOOLG:
4. Open the server services console: Start --> Run --> services.msc
5. Manually stop the OracleOHService service
p_id=BLOG_V1_OxnNhKpXNIUSEVzkmRYb96933864" alt="" style="word-wrap:break-word; border:0px">
6. Start the CRS stack in exclusive mode:
$CRS_HOME\bin\crsctl start crs -excl
...
CRS-2672: Attempting to start 'ora.asm' on 'racnode1'
CRS-2676: Start of 'ora.asm' on 'racnode1' succeeded
CRS-2672: Attempting to start 'ora.crsd' on 'racnode1'
CRS-2676: Start of 'ora.crsd' on 'racnode1' succeeded
$CRS_HOME\bin\crsctl start crs -excl -nocrs
...
CRS-2672: Attempting to start 'ora.cluster_interconnect.haip' on 'racnode1'
CRS-2672: Attempting to start 'ora.ctssd' on 'racnode1'
CRS-2676: Start of 'ora.drivers.acfs' on 'racnode1' succeeded
CRS-2676: Start of 'ora.ctssd' on 'racnode1' succeeded
CRS-2676: Start of 'ora.cluster_interconnect.haip' on 'racnode1' succeeded
CRS-2672: Attempting to start 'ora.asm' on 'racnode1'
CRS-2676: Start of 'ora.asm' on 'racnode1' succeeded
A new option '-nocrs' has been introduced with 11.2.0.2, which prevents the start of the ora.crsd resource. It is vital that this option is specified, otherwise the failure to start the ora.crsd resource will tear down ora.cluster_interconnect.haip, which
in turn will cause ASM to crash.
7. Re-create the OCRVOTE diskgroup via sqlplus
The disk group can now be (re-)created via sqlplus from the grid user. The compatible.asm attribute must be set to 11.2 in order for the disk group to be used by CRS:
SQL*Plus: Release 11.2.0.1.0 Production on Thu Sep 2 08:39:18 2010
Copyright (c) 1982, 2010, Oracle. All rights reserved.
Connected to:
Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production
With the Real Application Clusters and Automatic Storage Management options
SQL> CREATE DISKGROUP OCRVOTE NORMAL REDUNDANCY
DISK '\\.\ORCLDISKOCRVOTE0','\\.\ORCLDISKOCRVOTE1','\\.\ORCLDISKOCRVOTE2'
ATTRIBUTE 'compatible.asm'='11.2.0.0.0';
Diskgroup created.
SQL> exit
8. Restore the latest OCR backup
Now that the CRS disk group is created & mounted the OCR can be restored:
9. Start the CRS daemon on the current node (11.2.0.1 only !)
Now that the OCR has been restored the CRS daemon can be started, this is needed to recreate the Voting file. Skip this step for 11.2.0.2.0.
CRS-2672: Attempting to start 'ora.crsd' on 'racnode1'
CRS-2676: Start of 'ora.crsd' on 'racnode1' succeeded
10. Recreate the Voting file
The Voting file needs to be initialized in the CRS disk group:
Successful addition of voting disk 401738d9d75e4f7abf60d6bac7f9119c.
Successful addition of voting disk 7449ffaed19b4f22bf643553ea396683.
Successful addition of voting disk 5be68de758a74fbbbf9b8a4240d5e32d.
Successfully replaced voting disk group with +OCRVOTE.
CRS-4266: Voting file(s) successfully replaced
11. Recreate the SPFILE for ASM
Prepare a pfile (e.g. c:\tmp\asm_pfile.ora) with the ASM startup parameters - these may vary from the example below. If in doubt consult the ASM alert log as the ASM instance startup should
list all non-default parameter values. Please note the last startup of ASM (in step 2 via CRS start) will not have used an SPFILE, so a startup prior to the loss of the CRS disk group would need to be located.
*.diagnostic_dest='C:\app\11.2.0\grid'
*.instance_type='asm'
*.large_pool_size=12M
*.remote_login_passwordfile='EXCLUSIVE'
Now the SPFILE can be created using this PFILE:
SQL*Plus: Release 11.2.0.1.0 Production on Tue Mar 30 11:52:39 2010
Copyright (c) 1982, 2009, Oracle. All rights reserved.
Connected to:
Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - Production
With the Real Application Clusters and Automatic Storage Management options
SQL> create spfile='+OCRVOTE' from pfile='c:\tmp\asm_pfile.ora';
File created.
SQL> exit
12. shutdown CRS
Since CRS is running in exclusive mode, it needs to be shutdown to allow CRS to run on all nodes again. Use of the force (-f) option may be required:
...
CRS-2793: Shutdown of Oracle High Availability Services-managed resources on 'auw2k3' has completed
CRS-4133: Oracle High Availability Services has been stopped.
13. start CRS
As the root user submit the CRS startup on all cluster nodes:
CRS-4123: Oracle High Availability Services has been started.
14. Verify CRS
$CRS_HOME\bin\crsctl status resource -t
Errors:
PROT-602: Failed to retrieve data from the cluster registry
PROC-26: Error while accessing the physical storage ASM error [SLOS: cat=8, pn=kgfolclcpi1, dep=210, loc=kgfokge
AMDU-00210: No disks found in diskgroup OCRVOTE
AMDU-00210: No disks found in diskgroup OCRVOTE
