On ia64 hp Integrity BL860c i4 blade I can not see second internal disk

Hi!

I am running HP-ux 11.31 OS on my integrity. I tried running "ioscan -fNnkC disk" I can not see both internal disk. SMH does not show them either.

 

I wanted to DRD / clone the OS loaded disk to the other internal disk but I can not see it.

 

 # ioscan -fNnkC disk
Class     I  H/W Path  Driver S/W State   H/W Type     Description
===================================================================
disk      1  64000/0xfa00/0x1  esdisk   CLAIMED     DEVICE       HP      LOGICAL VOLUME
                      /dev/disk/disk1      /dev/disk/disk1_p2   /dev/rdisk/disk1     /dev/rdisk/disk1_p2
                      /dev/disk/disk1_p1   /dev/disk/disk1_p3   /dev/rdisk/disk1_p1  /dev/rdisk/disk1_p3

 

How to I activate / see disk 2?

 

Can someone please shed some light on my issue?

 

Thanks

Re: On ia64 hp Integrity BL860c i4 blade I can not see second internal disk

What you are seeing is a logical volume that, likely, consists of both disks.  This volume is managed by the onboard SAS/SA controller.

 

I am not sure on the i4 models, but the i2 models utilize the Smart Array P410i as the built in controller.  To view your current configuration do the following:

 

# ioscan -fnkN

 

  > look for the controller with the /dev/cissX driver that the disk volume is attached to.  Likely you will see /dev/ciss0 and /dev/ciss1

 

# saconfig /dev/ciss0  (and/or /dev/ciss1)

 

 > you will then see all of the physical drives.

Re: On ia64 hp Integrity BL860c i4 blade I can not see second internal disk

Hi Bob!

with ioscan, I only see  /dev/ciss0.

 

Do I have to initialize the second disk at EFI level?

 

I have not used EFI so I could check it out before asking this question.

 

Please suggest if you have more info on this issue.

 

Thanks

This is not a disk.  It is your RAID controller.

Re: On ia64 hp Integrity BL860c i4 blade I can not see second internal disk

Hi,

 

as you can see, your two disk (Enc 1 Bay 1 and Enc 1 Bay 2) are part of a RAID 1+0 logical volume.
So you cannot access the individual disks, but just the logical volume (/dev/disk/disk1... or /dev/dsk/c0t0d0).

 

The internal disk of an HP Integrity BL8x0c i4 Server are attached to the internal PCIe SAS SmartArray P410i RAID Controller.
This RAID controller can be set to either RAID MODE or HBA MODE.
In your case it is set to RAID MODE, so the individual disks are not seen by the OS, but you have configured a RAID volume with these two disks being in a RAID 1+0.
If you want to see the individual disks at the OS level, you have to switch to HBA MODE using the saupdate command at EFI. Note that you would lose all data, if you switch between the modes.
So normally it should first be planned which mode wants to be used and then install the OS.

 

See also the HP Integrity BL860c i4, BL870c i4 & BL890c i4 Server Blade User Service Guide for further information.
You can download the manual at HP Support Center:
http://www.hp.com/go/hpsc
 -> search for BL860c i4
  -> choose "Manuals" at the left

 

 

Kind Regards

Hi holger!

 

My EFI shell could not find saupdate comand in fs**:   

 

Any ideas?

You need to download the SAS IO Firmware Update package to get the utility.  The firmware and utility is placed on an EFI partition and then you can use it.  Might as well update your IO firmware if applicable while you are at it.

 

Try this link:

 

http://h20000.www2.hp.com/bizsupport/TechSupport/SoftwareDescription.jsp?lang=en&cc=us&prodTypeId=3709945&prodSeriesId=5330436&prodNameId=5330437&swEnvOID=54&swLang=8&mode=2&taskId=135&swItem=MTX-300ff32f7a8f49c79b842aa234

 

or go to www.hp.com/go/bizsupport

 - select Drivers and Downloads

 - Navigate to your server model

 - Select Cross Operating System, BIOS...

 - look for the firmware package.

 

 

The usage of saupdate is explained fairly well by the commands help/usage syntax.

 

Remember, by using saupdate to change your controller mode, you are going to lose the data/OS you have on your disks now.
