Disk /dev/sdb doesn't contain a valid partition table
Before the above I’ve done a mkfs on the new virtual disk, i.e.
[root@11gr2-secondary ~]# mkfs -t ext3 /dev/sd
sda sda1 sda2 sda3 sda4 sda5 sda6 sda7 sdb
[root@11gr2-secondary ~]# mkfs -t ext3 /dev/sd
sda sda1 sda2 sda3 sda4 sda5 sda6 sda7 sdb
[root@11gr2-secondary ~]# mkfs -t ext3 /dev/sd
sda sda1 sda2 sda3 sda4 sda5 sda6 sda7 sdb
[root@11gr2-secondary ~]# mkfs -t ext3 /dev/sdb
mke2fs 1.39 (29-May-2006)
/dev/sdb is entire device, not just one partition!
Proceed anyway? (y,n) y
