Multiple Adapters
The disk array drivers and firmware will support up to six adapters, but your
particular model of HP NetServer may have fewer PCI slots available. Be sure to
check your system's PCI I/O slot availability and any slot restrictions before
purchasing another adapter.
If you will be configuring more than one adapter, make one photocopy of
Worksheets A and B for each adapter.
Slot Selection and Boot Order
If you purchased an HP NetServer array model, then the adapter is already
installed in the PCI slot recommended for your system.
The table below lists the slots recommended for your HP NetServer. Using other
slots may cause IRQ conflicts and other problems.
