Issue

On an RSA Identity Governance & Lifecycle hard appliance, the database resides on an Oracle ASM partition.This article explains how to determine which set of disks comprise the Oracle ASM partition on an RSA Identity Governance & Lifecycle appliance.
 

Resolution

To determine which set of disks comprise the ASM partition, follow the steps below. Perform all commands as the root user.
 

1. Get the list of partitions using the fdisk -l command.  

# fdisk -l 

Disk /dev/sda: 53.6 GB, 53687091200 bytes 
255 heads, 63 sectors/track, 6527 cylinders 
Units = cylinders of 16065 * 512 = 8225280 bytes 

Device Boot Start End Blocks Id System 
/dev/sda1 * 1 13 104391 83 Linux 
/dev/sda2 14 2244 17920507+ 8e Linux LVM 
/dev/sda3 2245 6527 34403197+ 83 Linux

 

2. Run the querydisk command for each device listed in the output of the fdisk command

1. Format of the command:

/etc/init.d/oracleasm querydisk /dev/XXX

2. For example:

# /etc/init.d/oracleasm querydisk /dev/sda1
# /etc/init.d/oracleasm querydisk /dev/sda2
# /etc/init.d/oracleasm querydisk /dev/sda3

3. If the device is in the ASM partition, the output will look like:

Disk "/dev/sda1" is marked as an ASM disk with the label "VOL1"

4. For non-ASM volumes, the output will look like:

Disk "/dev/sda2" is not marked as an ASM disk
