VXDMP on RHEL with Oracle RAC + ASM

Level 3

Hello Friends,


We are running ORACLE RAC + ASM on RHEL.

we are using VXDMP for RAW disk.

we have an issue with ASM disk access for Oracle RAC. On startup, ASM auto-discovers its disks. Due to the way multipathing is setup on these servers (relying on Veritas DMP) it finds the first active device path instead of finding a multipath instance for it.  

The problem we are trying to resolve here is that if the in-use path goes down (such as from a SAN online maintenance) then oracle panics and crashes due to the loss of disk access with ASM.

can you guys suggest me the solution to this?

Can you please paste below commands ?

# oracleasm listdisks

# vxdisk -e list

# vxdisk path


Thank & Regads,
