Change lvols with mirror in Cluster

[Jose Juan]

Hi,
I need make a change in my system:
I???ve 4 lvols with mirror in the cluster???s disk and I want to put every lvol in a different disk.
I need the steps to do this correctly.
My system is HP-UX 11.0 with MirrorDisk/UX and ServiceGuard.

Thanks in advance.

I recommend you take a read of the Managing MC/ServiceGuard manual at:
http://docs.hp.com/hpux/ha
This has explanations of what and where, and hten you can also take a look at Managing Systems and Workgroups available at:
http://docs.hp.com/hpux/os/11.0/index.html#System%20Administration

if the disks are in the same logical volume

lvcreate -n [lvname] /dev/vg[vgname]

lvextend -L [MB] /dev/vg[vgname]/[lvname] /dev/dsk/[diskname].

Easy really!

Share and Enjoy! Ian

Hi,

I think you can use simply pvmove.

as long as your PV's are in same VG you can use pvmove to move your lvols from one PV to another .

See more details with man pvmove .

Hi,
I think that the steps could be:

1.- vgextend /VG /new disks
2.- lvsplit /lvols
3.- pvmove -n /lvol /new disk
4.- lvextend -m 1 /lvol /other new disk
5.- vgexport ...
ftp primary node -> alternative node
vgimport ...

is this correct?

Thanks

hi

remembet that lvsplit doesn't work with share mode so you can't use with cluster!!!!
