scsi disk mount problem
 
I just take the admin right of one HP Server with MSA1000 storage from my colleague. OS on HP is RHEL4 and MSA1000 is recognized by /dev/sdb. I found the /dev/sdb has no valid partition table. But mount /dev/sdb can execute sucessfully. It is my first time to see that we can mount scsi disk to OS without valid partition table. I wonder if it is possible.

The raw device is /dev/sdb. The partitions are probably /dev/sdb1, etc. Try mounting them.

Yes, as you say. When I add one new disk, I always do as follows.

# fdisk /dev/sdb
> n => press "n" key to add one new partition.
> wq => sync disk.

# fdisk -l ==> we can see /dev/sdb1 created as the step above.
# mkfs -t ext3 /dev/sdb1 /mnt

However, in our HP server, fdisk -l shows /dev/sdb has no valid partition.
but mount /dev/sdb /mnt is OK. I wonder whether we can mount scsi disk without valid partition table.
