Oracle 19c SEHA - Oracle ASM Disks are not available after Servers are restarted.

in Storage Management (ASM ACFS DNFS ODM) (MOSC) 17 commentsAnswered

Hi,

We implemented Oracle Standard Edition High Availability with Oracle 19c RAC (19.9) on Oracle Linux 7.9 (This for the Production DB System)

We are using Oracle ASM with ASMLIB and the Disks are using iSCSI and multipathing is configured.

Everything is working fine.

But when I restart the Linux Servers the ASM disks are not available in both nodes. I have to explicitly give

#oracleasm scandisks command in both nodes to scan the disks and then the ASM disks are available.

In both the nodes /etc/sysconfig/oracleasm has the following:

# ORACLEASM_SCANORDER: Matching patterns to order disk scanning

ORACLEASM_SCANORDER="dm"

Howdy, Stranger!
