IBM: Linux on System z
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.
