Error during pvmove operation on HP-UX B.11.23
Hi all,

But I'm getting following error:
# pvmove /dev/dsk/c11t0d2:05430 /dev/dsk/c11t0d0
Incorrect format of Physical Extent.
Usage: pvmove
[-A Autobackup]
[-n LogicalVolumeName]
SourcePhysicalVolumePath [ DestinationPhysicalVolumePath... | DestinationPhysicalVolumeGroupName... ]
or
pvmove [-A Autobackup] SourcePhysicalVolumePath[:0] [ DestinationPhysicalVolumePath... | DestinationPhysicalVolumeGroupName... ]
I've tried in different ways but I'm not able to do this operation.
Thanks in advance for your help!

Re: Error during pvmove operation on HP-UX B.11.23
From the manual of LVM in 11.31:
pvmove Command Syntax
Beginning with the September 2008 Update, pvmove provides these options:
-p Provides a preview of the move but does not actually perform the move.
-e no_of_extents Moves the last number of physical extents, specified by
no_of_extents.
de Specifies the starting location of the destination physical extents within
a destination physical volume.
se1 [-se2] Defines the source physical extent range, provided along with source
physical volume.
Beginning with the September 2009 Update, pvmove additionally provides these options:
-a Moves data to achieve auto-rebalance of disk space usage within a volume
group. Supported for Version 2.x volume groups only. See “Moving Data for
Disk Space Balancing: Auto Re-balancing” (page 75).
-f pv_path Moves data from the specified physical path, pv_path, to remaining physical
volumes to achieve balance. Supported only with the -a option.
-s Provides a summary preview report of the data move, but does not actually move
data. Used only with the -aand -poptions for a preview of data auto-rebalance.
See the pvmove(1M) manpage for details on all its options.
Your version of pvmove either don't understand this command you gave or you just gave the wrong value.
I would try
/dev/dsk/c11t0d2:5430 instead of /dev/dsk/c11t0d2:05430
Hope this helps!
Regards
Torsten.

Of course I tried without the zero and it doesn't work neither.
Thanks!

Re: Error during pvmove operation on HP-UX B.11.23
Yes you may...
Is not about moving one extent but a lot of them (to be exact the 256 that would fit into destination disk) to reorganise one volume that was created in a wrong way (for mirroring reasons).
I'd like to verify that it works ok on one extent before trying to move them all.
(I have also tried to pvmove a range and it doesn't work neither)
