Symptoms

Device Checks for ASM Failed:

Device Checks for ASM - This is a pre-check to verity if the specified devices meet the requirements for configuration through the Oracle Universal Storage Manager Configuration Assistant.

Verification result of failed node: racnode1

 List of errors:

  - PRVF-5150: Path ORCL:DISKCLU is not a valid path on all nodes

Operation Failed on Nodes: [racnode1]

 List of errors:

  -  Could not get the type of storage

     - Cause: Cause of Problem Not Available

     - Action: User Action Not Available

Cause

Unpublished bug 10026970

Solution

At the time of this writing, bug 10026970 is fixed in 11.2.0.3 which is not released yet. If ASM device passes manual verification, the warning can be ignored.

Manual Verification

To verify asmlib status:

/etc/init.d/oracleasm status

Checking if ASM is loaded:                                  [  OK  ]

Checking if /dev/oracleasm is mounted:                [  OK  ]

##  Both should be [OK]

To verify user setting in asmlib:
 

For environment without job role separation:
========
id <grid user>
uid=1001( grid) gid=1000( oinstall) groups=1000(oinstall)

/usr/sbin/oracleasm configure

ORACLEASM_ENABLED=true

ORACLEASM_UID= grid

ORACLEASM_GID= oinstall

ORACLEASM_SCANBOOT=true

ORACLEASM_SCANORDER=""

ORACLEASM_SCANEXCLUDE=""

For environment with job role separation:
========
id <grid user>
uid=1001( grid) gid=1000(oinstall) groups=1000(oinstall),1002(asmdba),1003(asmoper),1004( asmadmin)

/usr/sbin/oracleasm configure

ORACLEASM_ENABLED=true

ORACLEASM_UID= grid

ORACLEASM_GID= asmadmin

ORACLEASM_SCANBOOT=true

ORACLEASM_SCANORDER=""

ORACLEASM_SCANEXCLUDE=""

##  Note: Regardless job role separation, both ORACLEASM_UID and ORACLEASM_GID should match id output for grid user.

To verify disk

/etc/init.d/oracleasm listdisks

DISKCLU

ls -l /dev/oracleasm/disks

..

brw-rw----    1 grid oinstall        8,  33 Sep 16 09:41  DISKCLU

##  Note: In job role separation environment, group will be asmadmin instead of oinstall

dd if=/dev/oracleasm/disks/ DISKCLU of=/dev/null bs=1024k count=1

1+0 records in

1+0 records out

##  Note: Disk DISKCLU is available and readable from above output.
