can not add disks

I attached a disk array (HDS 5700 Disk Series)to our HP-UX Model E45 machine.After I boot the server, I cannot see the array but the local disks only by issue the command "ioscan -fnC disk" see following details of the output:

# ioscan -fnC disk
Class I H/W Path Driver S/W State H/W Type Description
===============================================================
disk 0 56/52.2.0 disc3 CLAIMED DEVICE TOSHIBA CD-ROM XM-3401TA
/dev/dsk/c2t2d0 /dev/rdsk/c2t2d0
/dev/floppy/c2t2d0 /dev/rfloppy/c2t2d0
disk 1 56/52.5.0 disc3 CLAIMED DEVICE HP C2247M1
/dev/dsk/c2t5d0 /dev/rdsk/c2t5d0
/dev/floppy/c2t5d0 /dev/rfloppy/c2t5d0
disk 2 56/52.6.0 disc3 CLAIMED DEVICE HP C2247M1
/dev/dsk/c2t6d0 /dev/rdsk/c2t6d0
/dev/floppy/c2t6d0 /dev/rfloppy/c2t6d0

But when I check the device files in /dev/rdsk, I can see the following:

# ll /dev/rdsk
total 0
crw-r----- 1 bin sys 177 0x005000 Mar 17 12:02 c0t5d0

crw-r----- 1 bin sys 177 0x026000 Aug 30 2001 c2t6d0

it seems that I have more disks on this system after I attached the disk.But if I check any of the disks other than the local ones, it shows that no such disks. see following:

# diskinfo /dev/rdsk/c0t5d1
diskinfo: can't open /dev/rdsk/c0t5d1: No such device or address

Anyone can tell me what the problems were and how to get it fixed? Thanks in advance.

Re: can not add disks

Check to see that the SCSI termination is correct. Has the unit got correct power?
Anyone for a Mutiny ?
