How to Manually Configure Disk Storage devices for use with Oracle ASM 11.2 on IBM: Linux on System z under RedHat 5 (Doc ID 1351746.1)

Last updated on FEBRUARY 13, 2019

Applies to:

Oracle Database - Enterprise Edition - Version 11.2.0.2 to 11.2.0.2 [Release 11.2]
Oracle Database Cloud Schema Service - Version N/A and later
Oracle Database Exadata Cloud Machine - Version N/A and later
Oracle Cloud Infrastructure - Database Service - Version N/A and later
Oracle Database Backup Service - Version N/A and later
IBM: Linux on System z

Goal

This article is applicable to RHEL 5.


ASMLib cannot be used in 11.2 and above with fcp/scsi devices due to a 512 block compatibility issue <Bug:12346221> on Linux for System z. In addition, ASMLib will be desupported in RHEL 6 releases going forward per <Document 1089399.1> This article provides platform specific examples for manually configuring eckd/dasd devices, single path scsi/fcp, and multi-path scsi/fcp/LUNS via udev rules and multipathing which provides the same functionality, flexibility and device persistence as oracleasm and ASMLib.
