SolutionThere is no need of formatting the HDD. When you run pvcreate on this disk, new lvm headers will be put into the new disk.
If you still want to erase the content of the disk then run dd on the disk.
# dd if=/dev/null of=/dev/rdsk/c1t5d0 bs=1024k
There is a command "mediainit" which will be used for low level disk formatting.

Re: How to format HDD for using in HP-ux
If you want to use dd to replicate data from one HDD to the one you had used for IRIX, then no need to do a dd if=/dev/zero ...., prior to this replication, because the use of dd for doing the replication itself would have overwritten all the data.
Also, you need not add the disk in any VG, because when you do a dd for the whole disk, the header information etc would also be overwritten by the data from your source disk.

Ninad

NO, need for that,
by performing the "pvcreate" command will be enough " if still cannot pvcreate
pvcreate -f (option -f will force creating new pshyical volume)but you need to make sure to specify "current device files"
Thanks,
Johnson

# dd if=/dev/zero of=/dev/rdsk/cXtXdX bs=1024k ; replace 'cXtXdX' with the correct disk file name.
