    Hi all,
    I'm having a strange problem with vdump. I'm on TU64 V5.1 PK4.
    I recently changed the hostname and ip address of my machine
    as part of a move to private ip space and am now running
    with an ip alias temporarily set to the old address, but
    now find that when trying to backup the root partition (a UFS one)
    vdump complains:

    'NFS2 server alf1.lmb.int not responding still trying'

    This is the hostname of the machine on which I am trying to do the
    backup, and I dont know why vdump thinks it is serving disks to
    itself, let alone whi it thinks its own host is not responding.
    I have always had vdump problems trying to back up /
    if ever there are other NFS servers whose filesystems I have
    mounted on my machine, and which happen to be offline at the
    time I do the vdump, but I've never seen this where vdump thinks
    its own host is offline. Ordinary dump operates satisfactorily.

    % ifconfig -a

    Name: alf1.lmb.int

    Any ideas anyone?

    Cheers,
