I'm not familiar with Buffalo NAS specifically but there are two different architectures of RAID controller.

One stores the array configuration information on the disks, including type of array (Raid 0,1,3,5,6 or whatever) and the disk member number of that array. When this type of controller fails you can replace it with a new one which, at boot, will read the disk labels and run with the previous RAID array(s).

The second, and most common type, stores the array configuration in its own NVRAM and if the controller fails you have to find a way of resetting the correct configuration into NVRAM. Often this is by using some new disks to configure the same array and then swapping the disks back to the originals. The manufacturer would usually be referred to for advice.

It seems to me like the NTFS filesystem is not as it was so your recovery technique was flawed. Perhaps the disks are in the wrong order or something like that. Kali doesn't like what it's seeing. It might be quicker to initialise the array and restore from backup.

CISS(4) 						   BSD Kernel Interfaces Manual 						   CISS(4)

NAME

     ciss -- HP/Compaq Smart ARRAY 5/6 RAID controllers

SYNOPSIS

     ciss* at pci? function ?

DESCRIPTION

     The ciss driver provides support for the CISS interface implemented by fifth and later generations of the HP/Compaq Smart ARRAY family of
     controllers.

     The CISS interface is defined in the document entitled CISS Command Interface for SCSI-3 Support Open Specification, Version 1.04, Valence
     Number 1, Compaq Computer Corporation, 2000/11/27.

     This driver supports several Compaq and HP controllers implementing the CISS interface, including:

     o	 Compaq Smart Array 5300 version 1
     o	 Compaq Smart Array 5300 version 2
     o	 Compaq Smart Array 5i version 1
     o	 Compaq Smart Array 5i version 2
     o	 HP Smart Array 5312
     o	 HP Smart Array 6i
     o	 HP Smart Array 641
     o	 HP Smart Array 642
     o	 HP Smart Array 6400
     o	 HP Smart Array 6400 EM
     o	 HP Smart Array E200
     o	 HP Smart Array E200i
     o	 HP Smart Array P400
     o	 HP Smart Array P400i
     o	 HP Smart Array P600
     o	 HP Smart Array P800
     o	 HP Smart Array V100
     o	 HP Smart Array 1 through 13

     These controllers support RAID 0, RAID 1, RAID 5, JBOD, and superpositions of those configurations.

     Although the controllers are actual RAID controllers, the ciss driver makes them look just like SCSI controllers.	All RAID configuration
     must be done through the controllers' BIOSes.

     Hardware from previous generations of this product family may be supported by the cac(4) driver.
