[SunHELP] problems with SCSI Disc partition

[joaquim at cnpq.br]

Hi all!!

I had installed Ubuntu 6.2 in SunBlade 150 Workstation connected to a
one D1000 with 12 SCSI discs with 18Gb each one.

This discs are:

Vendor: SEAGATE   Model: ST318404LSUN18G   Rev: 8590
Vendor: FUJITSU   Model: MAJ3182M SUN18G   Rev: 0804
Vendor: FUJITSU   Model: MAN3184M SUN18G   Rev: 1804

I4m using RAID 5 with mdadm to make this 12 discs in a big one, and
formated with raiserfs filesystem.

Everething working fine until a powerless saturday morning. System
crashed, and the operator run a wrong fsck in this metadevice.

I re-install system boot in another disc, but when I started this
D1000 10 of 12 discs return to me a information of

     "sdc: unknown partition table"

FDISK -L  return the same information.

Based in information of 2 discs that working fine, I tried to restore
partition table.

----->
Disk /dev/sda (Sun disk label): 19 heads, 248 sectors, 7506 cylinders
Units = cylinders of 4712 * 512 bytes

    Device Flag    Start       End    Blocks   Id  System
/dev/sda1             0      7506  17684136   83  Linux native
/dev/sda3             0      7506  17684136    5  Whole disk

But when I use fdisk I received a menu to choice a disk label. None of
them are 18Gb, I need to put all information in a custom type.

Building a new sun disklabel. Changes will remain in memory only,
until you decide to write them. After that, of course, the previous
content won't be recoverable.

New problem .. I duno what put in some variables.

----->
Alternate cylinders (0-65535, default 2):
Physical cylinders (0-65535, default 17274):
Extra sectors per cylinder (0-32, default 0):

Somebody have this information about the right partitions variable? I
coudnt find in any place like Fujitsu site.

More information about this disc follow above.

Thanks for any clue (sorry my "poor" english).
