参考原文:
Oracle Linux and External Storage Systems (Doc ID 753050.1)

Linux x86-64
Linux x86
Linux Itanium

目的:
本文展示了oracle linux 配置中与 外部存储系统相关的信息。
注意:这个列表可能不完整 或者不是最新的。对于细节,请参考下面提供的连接

范围:
本文可以被系统工程师和管理员用来作为 创建一个新oracle linux 系统的参考。

细节:

DM-MPIO
DM-MPIO 表示 Device Mapper Multipathing I/O
oracle linux 和 rhel 都包括DM-MPIO技术,该技术在各个厂商(比如emc)的紧密配合中被开发出来。
DM-MPIO 有包括但是限于下面的优势:

第一:User and kernel space tools for management and support
第二:当升级kernel时,有更大的灵活性。因为DM-MPIO已经被上游的 Linux kernel development team 所接受
换句话说:更新后的driver(驱动)会被传递给各个更新后的kernel中
而另一方面,若是使用第三方厂商的驱动,在新的kernel 版本,有新的驱动包(driver package)对应。
第三:Boot-from-SAN support is much easier to setup with DM-MPIO
第四:Multipathing support available during installation of OS
第五:Hardware vendors are starting to recommend/support DM-MPIO in certain storage configurations


For more information on DM-MPIO and also for various cases / implementations see

http://wiki.oracle.com/page/multipathd.conf+configuration+for+Data+ONTAP+7.2.x+with+ALUA?t=anon

Oracle Validated Configurations
For specific external storage (HP, EMC, NEC, Sun, Compellent, Dell, NetApp, Inspur, Pillar and more) configurations with Oracle Linux please:

Browse to http://linux.oracle.com/validated-configurations
Enter "OEL" in the search box. Click "Go" - that will provide you older validations but still applicable
Enter "Linux" in the search box. Click "Go"
See also the Oracle Technology Network Validated Configurations page

推荐:

第一:
第二:用 'cat /proc/partitions' and 'dmesg' 命令来验证 lun
第三:在可能的环境中,使用与linux kernel集成的driver,不要使用第三方的驱动
第四:OCFS2 1.2 does not support online filesystem resize.
Use OCFS2 1.4 or later to have resize enabled with OCFS2.
第五:对于各个cluster nodes 之间的共享文件系统,使用ocfs2、gfs,别使用nfs
