SunOS 5.5 Devices pln(7D)

NAME pln − SPARCstorage Array SCSI Host Bus Adapter Driver

SYNOPSIS pln@SUNW,pln@a0000800,200611b9

DESCRIPTION The pln Host Bus Adapter (HBA) driver is a SCSA compliant nexus driver which supports

the SPARC Storage Array. TheSPARC Storage Array is a disk array device which supports

30 disk drives. The drives are located on six SCSI busses within the SPARC Storage Array.

A SPARC microprocessor controls the SPARC Storage Array. Non-volatile RAM is used as

a disk cache. The SPARC Storage Array interfaces to the host system using Fibre Channel.

An SBus card called theSOC card (see soc(7D)) connects the Fibre Channel to the host

system.

The pln driver interfaces with theSOC device driver, soc(7D), and theSPARC Storage

Array SCSI target driver, ssd(7D).

The pln driver supports the standard functions provided by theSCSA interface. The

driver supports tagged and untagged queuing and auto request sense.

DIAGNOSTICS The messages described below may appear on the system console and in the system log.

This following messages indicate the pln driver was unable to attach to the device. These

messages are preceded by "pln%d", where "%d" is the instance number of the pln con-

troller.

Failed to alloc soft state

Driver was unable to allocate space for the internal state structure. Driver did

not attach to device. SCSI devices will be inaccessible.

Bad soft state

Driver requested an invalid internal state structure. Driver did not attach to dev-

ice. SCSI devices will be inaccessible.

Unable to attach

Driver was unable to attach to the hardware for some reason that may be

printed. SCSI devices will be inaccessible.
