Possible Device File Collision
(SR 8606459127) Executing the newfs or mkfs command for an EVFS volume can fail on systems
with components that call alloc_fake_device(), such as systems that are NFS clients. This
problem is caused by a defect in the alloc_fake_device() routine.
Symptoms
The newfs or mkfs command fails with a message similar to the following:
vxfs mkfs: /dev/evfs/vg01/relvol1 is mounted, cannot mkfs
The output from the lsdev command shows that the character major number used by the device
driver fake is the same as the block major number used by the device driver evfsevol. In the
example that follows, the common number is 2:
# lsdev
Character Block Driver Class
:
:
2 -1 fake pseudo
:
:
115 2 evfsevol pseudo
Workaround
The following workaround is only necessary and applicable to HP-UX 11i v2 Update 2.
