IOPSP(4) | Kernel Interfaces Manual | IOPSP(4) |
IOPs present each child peripheral attached to a bus adapter port as an individual device. In order to present the appearance of a bus, the iopsp driver groups child peripherals by controlling port.
On IOPs containing a SCSI port and block or tape driver modules, some SCSI devices may not be directly accessible. For each inaccessible device, a message will be displayed during configuration. For example:
iopsp0: target 0,0 (tid 70): in use by tid 47
Such devices will usually be indirectly accessible as block devices, either individually or as part of an array.
