MO Drive

Hi all...

I am having a problem mounting a SCSI MO Drive in SunOS / HPUX, I can see the drive from a scsi probe, but can't get itr working...

My Unix knowledge is sketchy...

can anyone give me a step by step guide ?

As soon as you plug the device in (on "id5" usually) and powered up the Sparc (Sun OS)

the following came up....
Code:
 
     scsi0 : Sparc ESP100A-FAST
     scsi : 1 host.
     Vendor: SAMSUNG   Model: WN32162U          Rev: 0100
     Type:   Direct-Access                      ANSI SCSI revision: 02
     
     Detected scsi disk sda at scsi0, channel 0, id 3, lun 0
     Vendor: MATSHITA  Model: LF-7010  (00:06)  Rev: 1.42
     Type:   Optical Device                     ANSI SCSI revision: 02
     Detected scsi removable disk sdb at scsi0, channel 0, id 5, lun 0 scsi 
     : detected 2 SCSI disks total.
     esp0: target 3 [period 100ns offset 15 10.00MHz FAST SCSI-II]
     SCSI device sda: hdwr sector= 512 bytes. Sectors= 4236661 [2068 MB] 
     [2.1 GB]
     esp0: target 5 [period 248ns offset 4 4.03MHz synchronous SCSI] sdb : 
     READ CAPACITY failed.
     sdb : status = 0, message = 00, host = 0, driver = 28 sdb : extended 
     sense code = 2 
     sdb : block size assumed to be 512 bytes, disk size 1GB.  
     sunlance.c:v1.9 21/Aug/96 Miguel de Icaza (miguel@nuclecu.unam.mx) 
     eth0: LANCE 08:00:20:04:3d:cf 
     eth0: using auto-carrier-detection.
     Partition check:
     sda: sda1 sda2 sda3 sda4 sda5 sda6 sda7 sda8
     sdb:scsidisk I/O error: dev 08:10, sector 0, absolute sector 0   unable to read partition table

edit fstab, and add the highlited entry for the drive (on sdb)
Code:
     ==========
     /etc/fstab
     ==========
     /dev/sda1          /                       ext2    defaults        1 1 
     /dev/sda2          swap                    swap    defaults        0 0 
     /dev/fd0           /mnt/floppy             msdos   noauto,user     0 0 
     /dev/sr0           /mnt/cdrom              iso9660 noauto,ro,user  0 0 
     /dev/sdb           /mnt/optical            ext2    noauto,rw,user  0 0 
     none               /proc                   proc    defaults        0 0

Then mkfs'ed a blank disc as follows...

[root@localhost root]# /sbin/mkfs -t ext2 /dev/sdb

You will recieve something similar like this..

Code:
     mke2fs 1.10, 24-Apr-97 for EXT2 FS 0.5b, 95/08/09 /dev/sdb is entire 
     device, not just one partition! Proceed anyway? (y,n) y

     Writing inode tables: done     
     Writing superblocks and filesystem accounting information: done

reboot..
mounted the drive...
since you edited the fstab, add the following mount-point...

Code:
     /dev/sdb           /mnt/dostical          msdos   noauto,rw,user 0 0

you can now mount ext2 or dos formatted optical carts by mounting either optical or dostical.
Post back if that doesnt help.
