lvextend -m 1 failing

[Venkat_11]

When i am trying to mirror the root disk by using the following commands i am getting the following errors.

# lvextend -m 1 /dev/vg00/lvol3 /dev/dsk/c2t1d0
Usage: lvextend
[-A Autobackup]
{-l LogicalExtentsNumber |
-L LogicalVolumeSize}
LogicalVolumePath [ PhysicalVolumePath... | PhysicalVolumeGroupName... ]
"m": Illegal option.
Can any body advice me why its ending like this.
Thanks

Hi Venkat:

I suspect that you do not have a MirrorDisk/UX licence. Check with:

# swlist -l fileset|grep -i mirror

It sounds like you don't have the MirrorDisk/UX product installed. Check with "swlist -l product |grep -i mirror". You should see something like:
# swlist -l fileset |grep -i mirror
LVM.LVM-MIRROR-RUN B.11.11 LVM-MIRROR-RUN

Are you sure you have mirrordisk-UX software? Please, check from

swlist -l fileset |grep -i mirror

to confirm if this is in your system.

If it is then, what o/s are we talking about so that we could have a better discussion.

Venkat,

You need to have the Mirror Disk UX product installed on your system. You need to purchase this product.

Hi

You need to have mirror-ux installed, you check like this

#swlist -l fileset|grep -i mirror
LVM.LVM-MIRROR-RUN B.11.11 LVM-MIRROR-RUN
PHCO_30698.LVM-MIRROR-RUN 1.0 LVM.LVM-MIRROR-RUN

I am sure that Mirror Disk UX product is not installed on your system.
You need to purchase this product then install it on your server

If i installed Mirror Disk UX product does the system required reboot?? and can any one send the installation procedure for Mirror Disk UX product. I am running HPUX 11i.

Thanks a lot for all people who ever responced.

Yes, installing MirrorDisk causes a reboot.

[melvyn burnard]

use swinstall to install MirrorDisk/UX

Hi;

Please check if mirror package is installed.

#swlist -l product |grep -i mirror

if is installed.. check the following command before u perform any mirror operation.

#lvdisplay -v /dev/vg00/lvol3

see the output carefully. also check the physical disk used by the file system.

#vgdisplay -v vg00

check if u have enough free space available in target disk(/dev/dsk/c2t1d0)

Hope this will help u to resolve ur issue..

cheers

Hi,

If you are able to issue a lvchange â s g /dev/vg00/lvol1 to set the strict allocation policy but are unable to lvextend â m 1 /dev/vg00/lvol1 /dev/dsk/c1t2d0 this would point to me you do not have Mirror UX installed.
