Hi Neo,

As further checking, I can see it is local disk with RAID 5 in "Change/Show PCI-X SCSI pdisk" in smitty. As shown below, it's a disk inside the hdisk5 scsi raid 5 disk array.

Code:
xxx@/#lsdev -Cc disk
hdisk0 Available 04-08-ff-0,0 SCSI RAID 10 Disk Array
hdisk2 Available 00-08-02     1814     DS4700 Disk Array Device
hdisk3 Available 00-08-02     1814     DS4700 Disk Array Device
hdisk4 Available 00-08-02     1814     DS4700 Disk Array Device
hdisk5 Available 04-08-ff-0,1 SCSI RAID 5 Disk Array

So I though, just take out the missing disk, insert the new disk and format it with "create an array candiate pdisk and format to 512 byte sectors". But I'm not sure about this.

Code:
 
                                              x                       Change/Show PCI-X SCSI pdisk                       x
                                              x                                                                          x

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.

HISTORY

     The ciss driver first appeared in NetBSD 3.1.

     The ciss driver was written by Michael Shalayeff <mickey@openbsd.org>, and ported to NetBSD by Tonnerre Lombard <tonnerre@netbsd.org>.
