Disks aren't showing up in Solaris/OBP
(Disclaimer: I put this in the "dummies" section because I am a UNIX noob and I'm not really sure what I'm doing so I felt like it belonged here. If it belongs in the Solaris section I can delete this and post it thereSmilie)

I was handed over an Oracle SPARC T3-1 machine at work, with 8 physical disks installed. I installed Solaris 11 on one of the disks, but when I boot the OS up, only two disks appear:

Code:
AVAILABLE DISK SELECTIONS:
       0. c3t0d0 <LSI-MR9261-8i-2.12 cyl 65533 alt 2 hd 287 sec 31>
          /pci@400/pci@2/pci@0/pci@c/LSI,mrsas@0/sd@0,0
       1. c3t1d0 <LSI-MR9261-8i-2.12 cyl 65533 alt 2 hd 287 sec 31>
          /pci@400/pci@2/pci@0/pci@c/LSI,mrsas@0/sd@1,0

I don't think there is a RAID configuration set up on this machine (is this the proper way to check?):


Code:
{0} ok select scsi0
{0} ok show-volumes
No volumes to show
{0} ok show-children
FCode Version 1.00.54, MPT Version 2.00, Firmware Version 5.05.00.00
{0} ok

{0} ok select scsi1
{0} ok show-volumes
No volumes to show
{0} ok show-children
FCode Version 1.00.54, MPT Version 2.00, Firmware Version 5.05.00.00
Target 9
  Unit 0   Removable Read Only device   TEAC     DV-W28SS-V       1.0B
  SATA device  PhyNum 6
{0} ok

I looked these commands up online (select scsi0, show-volumes) so I'm not sure if this is the correct way to check for RAID configuration. However, the results do look different from our other T3-1 machine, which shows all 8 disks properly:


Code:
{0} ok select scsi0
{0} ok show-volumes
No volumes to show
{0} ok show-children

{0} ok

I'm not very familiar with the OK prompt, sorry if this is an obvious question. I also have the output of "show-disks" and "devalias" from both systems, if that helps.

Any ideas why my disks aren't all showing up in Solaris?

Thank you in advance!

What does the output of:

probe-scsi-all
say?

Be careful if there's data on the disks that you need!!!

It might just be that the disks aren't "labelled" with a Sun label. When labelled properly a Sun box can read the label and identify the drive.

You can write new labels to the drive(s) by launching the format command with the -e switch (expert mode) which will give you access to a "scsi" menu. Again be careful if there's data on the drives that you need.

Hope that helps.

You always have to consider that there might be a hardware or connection problem that prevents the machine from seeing the disks.

Can u share below outputs ?

On Solaris

Code:

raidctl -l c3t1d0

On ok prompt

I'm guessing that doesn't look good... Smilie

Luckily there's no important data on the disks, so I'm okay with losing everything as long as I can get all of the disks recognized. I tried running 'format -e' and it looks like it still only sees two disks, unless I misunderstood and I was supposed to run this from the OK prompt:
Code:
root@solaris11:~# format -e
Searching for disks...done


AVAILABLE DISK SELECTIONS:
       0. c3t0d0 <LSI-MR9261-8i-2.12 cyl 65533 alt 2 hd 287 sec 31>

       1. c3t1d0 <LSI-MR9261-8i-2.12 cyl 65533 alt 2 hd 287 sec 31>
          /pci@400/pci@2/pci@0/pci@c/LSI,mrsas@0/sd@1,0

Hm I hadn't thought of that, maybe I should take out and reseat the disks. Thank you for your help!

Needs to be

Code:
 
probe-scsi-all

at the ok prompt; including the hyphens.

---------- Post updated at 06:57 PM ---------- Previous update was at 06:56 PM ----------

Try using:

Code:
 
format -e

from Solaris (#). Get into the scsi menu. Nothing to lose if you don't need the data on the disks.

Sure:
Code:
root@solaris11:~# raidctl -l c3t0d0
Controller device can not be found.

root@solaris11:~# raidctl -l c3t1d0
Controller device can not be found.

I believe 'raidctl' might not be supported on the T3-1 hardware. At least that's according to a couple forum posts I've read. (cant post URLs because I don't have 5 posts yet)
