Coexistence of IBMMultipath Subsystem Device Driver (SDD) and PVLinks on HP 9000 and HP Integrity servers

If you want to use physical volume links (PVLinks) for multipathing a volume while the IBMMultipath Subsystem Device Driver (SDD) is installed, you must ensure that SDD does not configure a vpath for that volume.

To do this, add the serial number of any volumes that you want SDD to ignore to the /etc/vpathmanualexcl.cfg file.

Note: If you are using the SAN boot function, SDD automatically ignores the boot volume.
