Hi,

I got the right answer (from Casper.Dik@holland.sun.com) within two hours
after my mail (original question below).

A quick search on sunsolve showed, that this patch is not publicly available.
But fortunately we were under contract and I found the patch on out
Sunsolve CD.

I tested it on one machine (cavallo) so far and even witout -e the
disks was recognized fine, and I could write a label without problems.
A mkfs'ed a big filesystem and now everything seems running fine.
Thanks Casper!

Andreas

BTW Beside Casper's answer I received 7 "Out of Office AutoReply" and one
message that XXXX is not working for MasterCard anymore.
I remember the good old times, when people using vacancy programs bothered
about (non-)replies to mailing lists. I feel these times have gone ......

--------------------------------------------------------------------------
Original message:

I have an RAID array with one of those Zero-D controllers
(SCSI, disks are cheap IDE).
It is recognized with a probe-scsi:

ok probe-scsi
[...]
Target 0
  Unit 0 Disk Zero-D 460

I boot -r and get the following on two different machines:

On the first machine (pal) format dumps core:

# uname -a
SunOS pal 5.6 Generic_105181-11 sun4u sparc SUNW,UltraSPARC-IIi-Engine
# format
Searching for disks...WARNING: /pci@1f,0/pci@1/scsi@1,1/sd@0,0 (sd15):
        corrupt label - wrong magic number

Assertion failed: *dim2 >= *dim3, file auto_sense.c, line 1619
Abort - core dumped
#

On the ssecond machine format starts but fails to autoconfigure:

# uname -a
SunOS cavallo 5.6 Generic_105181-03 sun4u sparc SUNW,UltraSPARC-IIi-Engine
# format
Searching for disks...done

AVAILABLE DISK SELECTIONS:
       0. c0t0d0 <IBM-DNES-318350W-SA30 cyl 11199 alt 2 hd 10 sec 320>
          /pci@1f,0/pci@1/scsi@1/sd@0,0
       1. c0t1d0 <IBM-DNES-318350W-SA30 cyl 11199 alt 2 hd 10 sec 320>
          /pci@1f,0/pci@1/scsi@1/sd@1,0
       2. c0t3d0 <IBM-DRHS36V-0110 cyl 10021 alt 2 hd 20 sec 360>
          /pci@1f,0/pci@1/scsi@1/sd@3,0
       3. c1t0d0 <drive type unknown>
          /pci@1f,0/pci@1/scsi@1,1/sd@0,0
Specify disk (enter its number):

[ The list of vailable disk drives appears, among them: ]
AVAILABLE DRIVE TYPES:
        0. Auto configure
[...]
        18. other

Specify disk type (enter its number): 0
Must reformat device to 512-byte blocksize. Continue? y
Auto configure failed

So nothing can be done with the array in both cases.

Any ideas or reports of successful use of such a beast?

TIA

Andreas
