SUSE Linux Enterprise Server 9
In SUSE Linux Enterprise Server 9, it is not possible to partition multipath I/O devices themselves.
If the underlying physical device is already partitioned, the multipath I/O device reflects those
partitions and the layer provides
the partitions through the multipath I/O layer. As a consequence, the devices need to be partitioned
prior to enabling multipath I/O. If you change the partitioning in the running system, DM-MP does
not automatically detect and reflect these changes. The device must be reinitialized, which usually
requires a reboot.
5.2.7 Supported Architectures for Multipath I/O
The multipathing drivers and tools in SUSE
supported processor architectures: IA32, AMD64/EM64T, IPF/IA64, p-Series (32-bit/64-bit), z-
Series (31-bit and 64-bit).
5.2.8 Supported Storage Arrays for Multipathing
The multipathing drivers and tools in SUSE Linux Enterprise Server 10 support most storage arrays.
The storage array that houses the multipathed device must support multipathing in order to use the
multipathing drivers and tools. Some storage array vendors provide their own multipathing
management tools. Consult the vendor's hardware documentation to determine what settings are
required.
