hpvmcreate on san disk fails

[Medavie]

While trying to create a new vm on a complete san disk on the host. I get the message "hpvmcreate: WARNING (bchp901): Device file '/dev/rdsk/c9t0d2' in use by server". Initialy this drive was used to test creating vm's on logical volumes, but I have removed the volume group and the lvm info (pvremove) from the drive. I even re-booted the host to free up any allocations but still it seems to think that the drive is allocated. I have another san drive which is VirtualLVdisk and I shutdown the guest vm's as well to ensure that nothing on those vm's were holding the drive I am trying to install on.
Here is my hpvmcreate statement
hpvmcreate -P bchp901 -O hpux -c 2 -e 30 -r 4g -a disk:scsi::disk:/dev/rdsk/c9t0d2 -a network:lan::vswitch:HPswch2 -a dvd:scsi::disk:/dev/rdsk/c33t2d0

Any help appreciated.

try doing a dd to the device to ensure any header info is blown away:
dd if=/stand/vmunix of=/dev/rdsk/c9t0d2 bs=1024k

I tried the suggestion and still getting the same result.

Found the problem, there was an entry in the vm database for that drive. We assume it was put there when the drive was used with LVM. We used hpvmdevmgmt to remove the rdev and then attempted to do the create once again. This time it worked. I little gotcha, that I hope others will not have.

Fixed as stated above
