how to add SCSI external disks to 11.11

[Bruno Arruda]

Hi all,

i'm new on UX, I need to know how to add external disks on HPUX 11.11.
I have SE external enclosure with 8 disks.
anybody can help me ?

tks Bruno

I already plugged the storage to the server, and i tried to run the SAM -> disks and file systems -> diagnose missing disks

but i found only the internal disks.

thanks for any help

hi,

providing you are connected to the correct interface and have no scsi id conflicts, then the easiest way would be to just reboot the box. this should pick up the new drives and create the required device files for you.

if you do not want to reboot the box then do a full ioscan first
#ioscan
then do and insf to insatll the device files
#insf -e
then a full ioscan again to rescan
#ioscan

and then you should be able to see the disks with
#ioscan -funC disk

once seen here you can then atart to get the disks ready for use with either SAM or command line

You also need to make sure of correct termination

Hi Andy,

the SCSI ID is

0/0/2/0 ext_bus SCSI C87x Fast Wide Single-Ended
0/0/2/0.7 target
0/0/2/0.7.0 ctl Initiator

I plugged the disk enclosure with scsi cable between 2 above connectors..
and plugged the server on the left bellow.
But i'm still can't see the external disks...

# ioscan -funC disk
Class I H/W Path Driver S/W State H/W Type Description
======================================================================
disk 1 0/0/1/1.15.0 sdisk CLAIMED DEVICE HP 18.2GMAN3184MC
/dev/dsk/c1t15d0 /dev/rdsk/c1t15d0
disk 2 0/0/2/1.15.0 sdisk CLAIMED DEVICE HP 18.2GMAN3184MC
/dev/dsk/c3t15d0 /dev/rdsk/c3t15d0


there are some commend like "format" (solaris) ??

thanks.

bruno,

what is the type of enclosure? is it HP if so then can you tell me the part number or name of it, and also the part number of the disks and I will try and see if its compatible.

Hp has in the past made enclosures like the M12H that takes se scsi disks but need to be connected to a FWD scsi bus, as they have convertors in them.

some idea of the server would help aswell.

there is no format command either in hpux. Once the drives are seen you will need to pvcreate the drives, to prepare them for use. SAM does this for you if you prefer.

This may be obvious but from the ioscan you included the system does not see the disks.

1) disk is not FW SCSI
2) disk is not powered on

As mentioned take a look at the specs for your new disk.

ioscan is the command to rescan the bus and show you the devices.
