"vgimport unable to read the physical volume"
At this point I get the error message "vgimport unable to read the physical volume" . I tried to vgexport the devices, and it reported that the lvmtab entries for the new disk do not exist. Something didn't work (vgchgid?) but I saw no indications of anything.
This should have worked, as I already have a set of filesystems mounted on other bcv's on this system. And I re-used the script which worked before, changing the device and vg info.
The system is an N-4000 running HP-UX 11.0.

Re: "vgimport unable to read the physical volume"
Most likely you might have not specified all the disks in the command line while doing vgchgid.
If that is not the case, then your LVM headers might have been lost
during the synchronization. You could verify it using vgscan -v command after backing up /etc/lvmtab. But most likely it may not help as vgimport itself does a scan on the disks specified.

Re: "vgimport unable to read the physical volume"
This is a rough outline on what I've done before
# vgchange -a n /dev/myvg
# vgexport /dev/myvg
Establish your link from your real volumes to your BCV's to get up to data data.
Split your BCV
# mkdir /dev/myvg
# mknod ....
# vgchgid .... /dev/rdsk/cxtydz(if no errors should be okay)
# vgimport .... /dev/dsk/cxtydz (with preview option, if no errors should work)
If your using a script, make sure that at each point in the script that there is deal of error checking otherwise you won't know exactly where the problem is.

Re: "vgimport unable to read the physical volume"
Are you sure about the list of PVs you are passing to the vgimport command? Do they show up in 'ioscan -fn' and your 'inq' commands? If your 'vgchgid' didn't work you should see complaints in your syslog file.
