How to Manually Configure multipathed fcp/scsi devices for use with Oracle ASM 11.2 on IBM: Linux on System z under SLES 11 SP 2 and later (Doc ID 1584934.1)

Last updated on APRIL 24, 2017

Applies to:

Oracle Database - Enterprise Edition - Version 11.2.0.3 and later
IBM: Linux on System z

Goal

This article is applicable to SLES 11 SP2 (and later)   This is an addendum to <Document 1350008.1> as configuration has changed between SLES11 SP1 and SLES 11 SP2 to set up alias names and permissions for fcp/scsi multipath devices.

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 multi-path scsi/fcp/LUNS via udev rules and multipathing which provides the same functionality, flexibility and device persistence as oracleasm and ASMLib.

 

NOTE: If using an Oracle single instance database without ASM, with SLES 11 SP2 then an ext3 filesystem is the recommended file system type.
