I am a Linux system admin. Need help in below ASM disk issue...

I have deleted few disks which were marked for data and redo. aftrer deleting those disks, the cluster devices (vote disks) also went off. what could be wrong here

after doing oracle asm delete disk < data disk1...8>

did oracleasm scandisks

then it shows the below

Reloading disk partitions: done
Cleaning any stale ASM disks...
Cleaning disk "GRID_NPRD_109_CL_A_1G_01"
Cleaning disk "GRID_NPRD_109_CL_A_1G_02"
Cleaning disk "GRID_NPRD_109_CL_B_1G_01"

The above 3 are vote disks, I have not deleted them!

when I do oracleasm querydisk -p on them, it shows the below

oracleasm querydisk -p GRID_NPRD_109_CL_A_1G_01
Disk "GRID_NPRD_109_CL_A_1G_01" defines a device with no label

please help me here.. the GRID installation is performed by DBAs and I need to bring back these devices without initializing them.

    Welcome to the forums.

    What could be wrong here is that you deleted some ASM disks. Why did you do it? We don't know.

    Other things we don't know from your inquiry.
    version number
    code you ran
    justification for what you did
    log file output
    information we could use to determine whether those disks were is use or required

    My read on your post is "I did something wrong on some system and have no idea what I did please help me keep my job."

    Fair enough: Open an SR with MyOracleSupport.
