SSSRAID - 3SNIC SCSI RAID Controller driver

==============================================



This file describes the SSSRAID SCSI driver for 3SNIC

(http://www.3snic.com) RAID controllers. The SSSRAID

driver is the first generation RAID driver for 3SNIC Corp.



For 3SNIC SSSRAID controller support, enable the SSSRAID driver

when configuring the kernel.



SSSRAID specific entries in /sys

=================================



SSSRAID host attributes

------------------------

  - /sys/class/scsi_host/host*/csts_pp

  - /sys/class/scsi_host/host*/csts_shst

  - /sys/class/scsi_host/host*/csts_cfs

  - /sys/class/scsi_host/host*/csts_rdy

  - /sys/class/scsi_host/host*/fw_version



  The host csts_pp attribute is a read only attribute. This attribute

  indicates whether the controller is processing commands. If this attribute

  is set to ‘1’, then the controller is processing commands normally. If

  this attribute is cleared to ‘0’, then the controller has temporarily stopped

  processing commands in order to handle an event (e.g., firmware activation).



  The host csts_shst attribute is a read only attribute. This attribute

  indicates status of shutdown processing.The shutdown status values are defined

  as:

        ======     ==============================

        Value      Definition

        ======     ==============================

        00b        Normal operation

	01b        Shutdown processing occurring

	10b        Shutdown processing complete

	11b        Reserved

        ======     ==============================

  The host csts_cfs attribute is a read only attribute. This attribute is set to

  ’1’ when a fatal controller error occurred that could not be communicated in the

  appropriate Completion Queue. This bit is cleared to ‘0’ when a fatal controller

  error has not occurred.



  The host csts_rdy attribute is a read only attribute. This attribute is set to

  ‘1’ when the controller is ready to process submission queue entries.



  The fw_version attribute is read-only and will return the driver version and the

  controller firmware version.



SSSRAID scsi device attributes

------------------------------

  - /sys/class/scsi_device/X\:X\:X\:X/device/raid_level

  - /sys/class/scsi_device/X\:X\:X\:X/device/raid_state

  - /sys/class/scsi_device/X\:X\:X\:X/device/raid_resync



  The device raid_level attribute is a read only attribute. This attribute indicates

  RAID level of scsi device(will dispaly "NA" if scsi device is not virtual disk type).



  The device raid_state attribute is read-only and indicates RAID status of scsi

  device(will dispaly "NA" if scsi device is not virtual disk type).



  The device raid_resync attribute is read-only and indicates RAID rebuild processing

  of scsi device(will dispaly "NA" if scsi device is not virtual disk type).
