SDD : vgimport does not import vpath disk

Hi folks,

I'm getting a trouble in try to import a vg map file from one system to another that are using the same luns acress the storage, the vgimport command does not set the vpath devices afterwards, what the command is actually doing is to import the pvlnks instead.

does anyone know why I'm getting this weird behavior?

the OS version is a 11v1 and the SDD version is 1.8.0.2

command used:

[root@servera] vgexport -pvs -m /tmp/vgprod.map /dev/vgprod
[root@servera]

[root@serverx] vgimport -s -m /tmp/vgprod.map /dev/vgprod
[root@serverx]

Result:

[root@servera] /> swlist -l product | grep -i sdd
IBMsdd_tag 1.8.0.2 IBMsdd Driver 64-bit Version: 1.8.0.2 Sep-25-2008 09:29
[root@servera] />

[root@servera] /> vgdisplay -v /dev/vgprod | grep "PV N"
PV Name /dev/dsk/vpath1
PV Name /dev/dsk/vpath2
PV Name /dev/dsk/vpath3

[root@serverx] / > swlist -l product | grep -i sdd
IBMsdd_tag 1.8.0.2 IBMsdd Driver 64-bit Version: 1.8.0.2 Sep-25-2008 09:29

Shalom,

One of your alternate links might not be working.

I'd start out with some simple dd reads and make sure the alternate links are working on this system.

Hi Steven,

I just found a way to convert these sdisks to vpath devices through the hd2vp after activate the vg

# hd2vp /dev/vgprod

this take some time what actually works
