newfs: /dev/vg01/db is not a character device

[yassyboy]

Hi All,

I amm following the HP-UX System Admin 1 Training Manual to create new logical volume.

I have followed the following steps : -

1. dd if=/dev/zero of=/dev/rdsk/c3t5d0 bs=1024 count=1024

2. pvcreate -f /dev/rdsk/c3t5d0

3. mkdir /dev/vg01

4. mknod /dev/vg01/group c 64 0x010000

5. vgcreate vg01 /dev/dsk/c3t5d0

6. vgdisplay -v vg01
--- Volume groups ---
VG Name /dev/vg01
VG Write Access read/write
VG Status available
Max LV 255
Cur LV 10

Alloc PE 7821

7. lvcreate -L 12288 -n db vg01

# lvdisplay /dev/vg01/db

8. newfs -F vxfs /dev/vg01/db
vxfs newfs: /dev/vg01/db is not a character device


As per Sys Admin 1 I should be able to successfully create the vxfs.

Did I miss something?

[Torsten.]

Try

newfs -F vxfs /dev/vg01/rdb

(use "r"db!)

[melvyn burnard · Accepted solution]

well you have it all correct up to the newfs command, as you need to run this command against the character or raw device, hence the /dev/vg01/rdb device (note the r in rdb)

[Venkatesh BL]

Yes, and for mounting it, you need go back to using the block device (without 'r')

[yassyboy]

Thank you for all your guide.. POINTS Assigned...

Cant belive i missed "r"...LOL..

here is the result after mounting:
BDF -l


/dev/vg01/db 12582912 3686 12186134 0% /d/db

KR..Yxx

hi

Everything it has been corrected. In creating filesystem command also correct, but lats u should be add with r character. Example


/dev/dsk block device files for disk drives and cdrom

/dev/rdsk raw or character device files for disk drives
