ASM 磁盘组的的scrip

之前经常用如下方式进行查询：
步骤 1 以oracle用户登录系统。
步骤 2 执行如下命令改变ORACLE_SID环境变量。
$ export ORACLE_SID=+ASM1【1或者2】
需要通过ps -ef|grep ASM 确认实例名称
步骤 3 执行如下命令进入ASM管理状态。
$ asmcmd -p
步骤 4 执行如下命令查看存储空间。
$ ASMCMD> lsdg

[@more@]
最近发现如下的简易方式：

export ORACLE_SID=+ASM【1或者2】


需要通过ps -ef|grep ASM 确认实例名称

sqlplus "/as sysdba"

select name,TYPE,total_mb,free_mb,((total_mb-free_mb)/total_mb)*100 as usage from v$asm_diskgroup;


how to add asm_disk in aix:

SELECT SUBSTR(D.NAME,1,16) AS ASMDISK, D.MOUNT_STATUS, D.STATE,D.PATH,
DG.NAME AS DISKGROUP FROM V$ASM_DISKGROUP DG, V$ASM_DISK D
WHERE DG.GROUP_NUMBER = D.GROUP_NUMBER;

sample 1:

1) As Oracle or Grid OS user, run the next commands on each node (if ASMLIB API is used): 


# /etc/init.d/oracleasm  scandisks  #(only this command needs to be executed as root user)
$> id 
$> /etc/init.d/oracleasm  listdisks 
$> /etc/init.d/oracleasm  querydisk <each disk from previous output>

Note: All the disks must be visible from each node. 

2) Confirm the disks are visible (I/O) at OS level (as oracle or grid OS user) from each node:

$> id 
$> ls -l  <disk name> 
$> dd if=<raw/character or block partition device in  question> of=/dev/null count=100 bs=8192

Example: 

$> dd if=/dev/raw/raw1 of=/dev/null count=100 bs=8192  # raw device 
$> dd if=/dev/oracleasm/disks/PRODA07 of=/dev/null count=100 bs=8192  # ASMLIB device 
$> dd if=/dev/rdsk/c1t3d0s6 of=/dev/null count=100 bs=8192 # raw device

3) Verify that kfed can read on the candidate disk(s) at OS level (as oracle or grid OS user) from each node:

$> kfed read  <raw/character or block partition device in question>



Example:

$> kfed read /dev/raw/raw1

$> kfed read /dev/oracleasm/disks/PRODA07

$> kfed read /dev/rdsk/c1t3d0s6
Note: If the disk is not a FORMER disk, then kfed on new disks will return:    kfbh.type: 0 ; 0x002: KFBTYP_INVALID and that is expected.

 4) Create a new temporary diskgroup:

SQL> CREATE DISKGROUP TEST EXTERNAL REDUNDANCY DISK '<YOUR CANDIDATE DISK>';

5) Check if the diskgroup is created and mounted:

SQL> SELECT STATE, NAME FROM V$ASM_DISKGROUP;

6) If so, then manually mount it on the other ASM instance(s):

SQL> ALTER DISKGROUP TEST MOUNT; 
SQL> SELECT STATE, NAME FROM V$ASM_DISKGROUP;

7) If the previous steps had success and the TEST diskgroup can be successfully mounted (on each ASM instance), then drop the TEST diskgroup as follow:

SQL> alter diskgroup test dismount; --(from all the ASM instances, except from one). 

SQL> DROP DISKGROUP TEST; --(from the ASM instance, which the diskgroup is still mounted).

8) Then the candidate disk is ready to be added to the desired diskgroup: 

SQL> ALTER DISKGROUP <my production diskgroup> ADD DISK '<your candidate disk>';





Note: The same disks validation steps are also required for ASM Standalone configura

How To Gather & Backup ASM/ACFS Metadata In A Formatted Manner version 10.1, 10.2, 11.1, 11.2, 12.1 and 12.2? (文档 ID 470211.1)

Solution
Script #1 (Generic ASM metadata):
Script #2 (ASM Files & ASM Alias):
Script #3 (ASM Full Path Alias Directory):
Script #4 (ASMCMD commands to gather complementary metadata information):
Example Output (Script #1):
Example Output (Script #3):
Example Output (Script #4):
References
APPLIES TO:
Oracle Database - Enterprise Edition - Version 10.1.0.2 to 12.2.0.1 [Release 10.1 to 12.2]
Exadata Database Machine X2-2 Hardware - Version All Versions to All Versions [Release All Releases]
Information in this document applies to any platform.
***Checked for relevance on 30-Apr-2010***

GOAL
You can use the SQLPLUS “SET MARKUP HTML ON” to generate a formatted report from the existing ASM metadata and also using ASMCMD commands to gather complementary metadata information, which can be used as well as an ASM metadata backup or as a report for Oracle Support to troubleshot ASM issues.

SOLUTION
1) Connect to your ASM instance(s) and execute the first 3 scripts below (on each node if this is RAC configuration).

2) Also, execute the script #4 (located below) through ASMCMD to gather complementary metadata information (on each node if this is RAC configuration).

Note 1: Scripts #1, #2 & #3 could report the <<< ORA-01219: database not open: queries allowed on fixed tables/views only >>> error on some specific queries, due to some V$ASM_* performance views are only present on early ASM releases, therefore this errors can be ignored depending the ASM release.

Note: 2: This is the same case with the Script # 4 (ASMCMD commands), which could not interpret some ASMCMD commands, due to the some commands/options are not present on early releases.

######kfed issue 

KFED – ERROR!!! could not initialize the diag context

$ kfed read /u02/oradata/asm_disk0
ERROR!!! could not initialize the diag context




$ id
uid=503(grid) gid=501(oinstall) groups=501(oinstall),504(asmadmin),505(asmoper),506(asmdba)



$ ls -l /u02/oradata/asm_disk0
-rwxrwxrwx 1 grid oinstall 2097152000 Jul 5 22:14 /u02/oradata/asm_disk0

CAUSE

kfed executable will need create a directory for its own trace files under <GridHome>/log/diag/asmtool and/or  <GridBase>/diag/asmtool. If kfed firstly was used as root user, this directory - <GridHome>/log/diag/asmtool and/or  <GridBase>/diag/asmtoolis created as root. The following kfed run by other than root user will not be able to create a directory under <GridHome>/log/diag/asmtool. 


$ ls -l $ORACLE_HOME/log/diag

drwxrwxrwx 2 grid oinstall 4096 Jul 5 15:29 asm
drwxr-xr-x 3 root root 4096 Jul 6 11:17 asmtool << This directory is owned by root and there is no write permissin for other users.
drwxr-xr-x 5 oracle asmadmin 4096 Jun 20 09:16 rdbms
drwxrwxrwx 3 grid oinstall 4096 Jun 15 18:04 tnslsnr

或者: 

in grid:

truss kfed

statx("/c/igfs/oracleapp/diag", 0x0FFFFFFFFFFFD070, 176, 0) Err#2 ENOENT
mkdir("/c/igfs/oracleapp/diag", 0775) Err#13 EACCES
kioctl(1, 22528, 0x0000000000000000, 0x0000000000000000) = 0
ERROR!!! could not initialize the diag context
kwrite(1, " E R R O R ! ! ! c o u".., 48) = 48

SOLUTION

Change the owner for <GridHome>/log/diag/asmtool and/or  <GridBase>/diag/asmtool ( based on your GridHome version ) directory as grid user.

# chown grid:oinstall $ORACLE_HOME/log/diag/asmtool

And as grid user, the following command will show the correct kfed output.

$kfed read /u02/oradata/asm_disk0 | more
kfbh.endian: 1 ; 0x000: 0x01
kfbh.hard: 130 ; 0x001: 0x82

################

ASMLIB可能带来的缺点:

  1. 对于多路径设备(multipathing)需要在/etc/sysconfig/oracleasm-_dev_oracleasm配置文件中设置ORACLEASM_SCANORDER及ORACLEASM_SCANEXCLUDE，以便ASMLIB能找到正确的设备文件，具体可以参考Metalink Note<How To Setup ASM & ASMLIB On Native Linux Multipath Mapper disks? [ID 602952.1]>
  2. 因为ASM INSTANCE使用ASMLIB提供的asm disk，所以增加了额外的层面
  3. 每次Linux Kernel更新，都需要替换新的ASMLIB包
  4. 增加了因人为错误造成宕机downtime的可能
  5. 使用ASMLIB意味着要花费更多时间去创建和维护
  6. 因为ASMLIB的存在，可能引入更多的bug，这是我们最不想看到的
  7. 使用ASMLIB创建的disk，其disk header并不会和普通的asm disk header有什么不同，仅仅是在头部多出了ASMLIB的属性空间。

结论:
我个人的观点是尽可能不要使用ASMLIB，当然这不是DBA个人所能决定的事情。另一方面这取决于个人习惯，在rhel 4的早期发行版本中没有提供udev这样的设备管理服务，这导致在rhel 4中大量的ASM+RAC组合的系统使用ASMLIB , 经网友指出udev 作为kernel 2.6的新特性被引入，在rhel4的初始版本中就已经加入了udev绑定服务，但是在rhel4时代实际udev的使用并不广泛(In Linux 2.6, a new feature was introduced to simplify device management and hot plug capabilities. This feature is called udev and is a standard package in RHEL4 or Oracle
Enterprise Linux 4 (OEL4) as well as Novell’s SLES9 and SLES10.)。如果是在RHEL/OEL 5中那么你已经有充分的理由利用udev而放弃ASMLIB。

ASM Specific
    • Use ASMLib for ease of management and for increased performance provided by the ASMLib Async I/O driver.
      Note:  For RedHat Enterprise Linux 6 (beginning with 6.4) the kernel driver package 'kmod-oracleasm' is available directly from RedHat, and can be installed from the "RHEL Server Supplementary (v. 6 64-bit x86_64)" channel on RedHat Network (RHN).  Updates to this module will be provided by RedHat.  Additional information may be found in Document 1089399.1.
    • When using ASMLib in a multipath environment ensure that ASMLib has been configured properly such that the multipath device is used for access to the devices.  This is achieved by editing the /etc/sysconfig/oracleasm configuration file and modifying the ORACLEASM_SCANORDER to include a valid prefix entry from /proc/partitions (e.g. "dm","emcpower").  A common misconfiguration is to have ORACLEASM_SCANORDER" set to "/dev/mapper/".  "/dev/mapper: are aliases which will NOT exist in /proc/partitions.  See Document 602952.1 for details.
    • If you are NOT or are unable to use ASMLib please refer to Document 357472.1 for guidance on how to configure UDEV and/or Device Mapper to manage Clusterware and ASM devices.
    • On Linux 7 systems using FCOE and ASMLib, ensure FCOE service starts before ASMLib.  See Document 2065945.1 and Document 2043733.1 for additional details.

      3. Add the following ifcfg-* files in /etc/sysconfig/network-scripts/

      #cat /etc/sysconfig/network-scripts/ifcfg-bond0
      DEVICE=bond0
      IPADDR=xx.xx.xx.xx.
      NETMASK=x.x.x.x
      BROADCAST=x.x.x.x
      ONBOOT=YES
      BOOTPROTO=none
      USERCTL=no
      MTU=65520
      #cat /etc/sysconfig/network-scripts/ifcfg-ib0
      DEVICE=ib0
      USERCTL=no
      ONBOOT=yes
      MASTER=bond0
      BOOTPROTO=none
      SLAVE=yes
      HOTPLUG=no
      CONNECTED_MODE=yes
      MTU=65520
      #cat /etc/sysconfig/network-scripts/ifcfg-ib2
      DEVICE=ib2
      USERCTL=no
      ONBOOT=yes
      MASTER=bond0
      BOOTPROTO=none
      SLAVE=yes
      PRIMARY=yes
      HOTPLUG=no
      CONNECTED_MODE=yes
      MTU=65520
