Error:
Connecting to multiple shares on a single server with multiple credentials results in a “System Error 1219” error message.

Multiple connections to a server or shared resource by the same user, using more
than one user name, are not allowed. Disconnect all previous connections to the
server or shared resource and try again..

This error is by design. You may create an additional connection by using the hostname for one, and then the IP Address for the other.

How to Find ASM Disk to Physical Device Mapping

1. List Oracle ASM Disks

# /etc/init.d/oracleasm listdisks
DV242ASM00
DV242ASM01
DV242ASM02
EMCPPA1
EMCPPB1

2. Query Disk

# /etc/init.d/oracleasm querydisk -d EMCPPB1
Disk “EMCPPB1” is a valid ASM disk on device [8, 33]

3. Match Major/Minor Numbers to Physical Disk

# ls -l /dev | grep 8|grep 33
