access a storage system. Another is providing redundant paths from the host to the switch. To
determine if your multipathing software is supported, see the support matrix for your edition, which

• SANtricity Manager Utilities must be installed on the host running RDAC for the management
server to obtain RDAC information.
• HDLM on Sun Solaris requires the storage array to be included in discovery to report the correct
information back to the bindings page. See ” Known Device Issues ” on page 722 for more

multipathing.
• Microsoft Windows 2003 hosts with Service Pack 1 and IBM TotalStorage DS6800 arrays do
not stitch properly as a result of the Subsystem Device Driver (SDD) appearing on the same disk.
The multipathing page returns the Windows SDD path as something similar to
600507630efe01a80000000000001104:c0t0d0p3
. This makes it difficult to match it up to
your SDD path names.
• Elements managed by the QLogic F/O software display a blank value for Type of MP when you
view multipathing information.
The following figure shows how the software detects multipathing for a server running VERITAS
Volume Manager. MP is displayed on the path of the redundant volumes:
