• The “Maximum VCs per Adapter” also depends on the HP-UX systems available RAM at
system boot time—the driver checks the amount and limits the number of available VCs
accordingly. The table below shows, for each affected adapter, the amount of available
RAM and the corresponding VC limit. Note that discontinued adapters are not shown.
You also can use the atmmgr show -c command to display the maximum number of VCs
(called “VCCs” in the command’s output) for an adapter.
