Try
verify
and
inquiry
and
partition -> print -> quit

Usually you can just type the first letter of the command.
Do you get some reasonable results?

27 
format> verify
Current Disk Type is not set.
format> inquiry

That shows a Seagate ST973451SSUN72G ?
I thought it's a HP DG0146BALVN ?

Also try
type
Does it offer some types?

  • Yes Its Seagate drive. We put is just to check. Earlier we used HP disk. Both have same status. We put it for checking
  • I have shared the type response above. Let me share again

What is the history of these two disks? I assume that they are not new.

Try booting into single-user from the DVD installation media:

ok> boot cdrom -s

and at the root shell prompt (#) run format in expert mode:

# format -e

From the SCSI menu select option "set all mode pages to default" and then "label" the disk with a "SMI" type label. Then see if you can configure a partition.

31 
scsi> default all

Mode sense page 0x3f failed
scsi>
32

Do you get the same result with the other disk?

33

Yes

34

I think there is something wrong with the mpt_sas controller.
If it's not broken, maybe it's configured for RAID (instead of JBOD), and one may only query its failed logical drive? But then the show-volumes and show-children should have worked...
Is another (bad?) disk connected to this scsci bus?

35

This time No. I changed multiple drives while testing. All have shown same results. Any way we can check the Disk Controller/raid Controller are working fine thru command ?

36

Your RAID controller uses FCODE commands:

If there was no RAID arrays configured i.e. all drives on pass thru', then I would expect the 'show-volumes' command to say that no volumes exist.

If it does list a volume then delete that volume using 'delete-volume'.

37

I have already shared the response of show volume

{0} ok

**{0} ok select /pci@400/pci@1/pci@0/pci@4/scsi@0**
{0} ok show-volumes
No volumes to show```

I've just this whole topic through from the beginning to refresh my memory as to what has gone on.

You are getting this in response to SCSI enquiries after "auto-configure" fails. When auto-configure fails you should configure it manually using the 'type' command within 'format'.

As I can see, @MadeInGermany already suggested that but none of your posts state that you tried it.

See the 2nd menu option - 'type'

Try using that to manually set the drive type. If that works you still need to 'label' the disk afterwards.

REF: Read this from Oracle......

It does not offer any type. I discarded the machine
