Device is not marked as an ASM disk on a second node after scandisks on both nodes

User_QN1COMay 26 2016 — edited May 26 2016

Hello,

We encountered errors after installing Oracle Clusterware, and we are trying to reattempt an installation.

Oracle 11g 10.2.0.4, VM, Linux 5 with ASMLib.


We ran the deinstall to uninstall the grid infrastructure.

We ran dd if=/dev/zero of=/dev/sdb1 bs=1024 count=100 to reset all the partitions' headers.

We ran oracleasm deletedisk to unmarked all the partitions.


We marked a disk as ASM disk on A node


#oracleasm createdisk OCR1 /dev/mapper/KAM1ODDBS08AB_OCR1p1

Writing disk header: done

Instantiating disk: done

#oracleasm listdisks

OCR1

#oracleasm querydisk /dev/mapper/KAM1ODDBS08AB_OCR1p1

Device "/dev/mapper/KAM1ODDBS08AB_OCR1p1" is marked an ASM disk with the label "OCR1"

# oracleasm scandisks

Reloading disk partitions: done

Cleaning any stale ASM disks...

Scanning system for ASM disks...

ON B node, it is not able to see the disk marked being an ASM disk

# oracleasm scandisks

Reloading disk partitions: done

Cleaning any stale ASM disks...

Scanning system for ASM disks...

# oracleasm listdisks

# oracleasm querydisk /dev/mapper/KAM1ODDBS08AB_OCR1p1

Device "/dev/mapper/KAM1ODDBS08AB_OCR1p1" is not marked as an ASM disk

I have tried running # oracleasm init on both nodes, tried rebooting both nodes, tried # oracleasm configure on both nodes and they return the same configuration.

Please give me some ideas what could be the next thing I can check.
