Linux on IBM Z
This article is applicable to RHEL 6.2 and later This is an addendum to <Document 1351746.1> as configuration has changed between Redhat 5 and Redhat 6 to set up alias names, permissions for fcp/scsi multipath devices.
ASMLib cannot be used in 11.2 or 12.1 and above with fcp/scsi devices due to a 512 block compatibility issue <Bug:12346221> on Linux for System z. In addition, ASMLib may be desupported in RHEL 6 releases going forward. 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.
