Description
Error Message
# vxdisksetup -i c0t0d0 format=sliced
VxVM vxdisk ERROR V-5-1-16528 The device is in use. This device may be a boot disk. Device has a UFS FS on it.
If you still want to initialize this device for VxVM use, ensure that there is no root FS on it.
Then remove the FS signature from each of the slice(s) as follows:
dd if=/dev/zero of=/dev/vx/rdmp/c0t0d0s[n] oseek=18 bs=512 count=1
n] is the slice number.
Or alternatively you can rerun the same command with -r option
Cause
New feature introduced in version 6.0 to prevent overwriting root filesystem on a boot disk by mistake
Resolution
From the help page we have
# vxdisksetup -h (sample)
VxVM vxdisksetup INFO V-5-2-5958
vxdisksetup - setup a disk for use with the volume manager
Usage: vxdisksetup [-iefr] disk-device-address [ attribute ... ]
Options:
-i Initialize the private region
-e Allocate the private region at the end of the disk
-f Force
-r Force init if the disk has UFS FS on it
man page we have
# man vxdisksetup (sample)
-r Must be specified with the -f option to remove the UFS file system signature from a disk.
solution:
# vxdisksetup -ir c0t0d0 format=sliced ( test first without -f first, if it fails repeat with -f )
or
# vxdisksetup -fir c0t0d0 format=sliced
Applies To
VXVM 6.0 and above
