Question about Mirror/UX

I have Mirror/UX installed on a rx8640 with 11.31. However, when I attempt to use -m option on lvextend, it tells me illegal option.

:root:/root->lvextend -m 1 /dev/vg00/lvol1
Usage: lvextend
[-A Autobackup]
{-l LogicalExtentsNumber |
-L LogicalVolumeSize}
LogicalVolumePath [ PhysicalVolumePath... | PhysicalVolumeGroupName... ]
"m": Illegal option.


Checked that it installed.
root:/tmp->swlist -l product | grep -i mirror
LVM-MirrorDisk B.11.31 MirrorDisk/UX

Checked that is available in kernel.

root:/tmp->strings /stand/vmunix | grep -i mirror RAID 1+0 - Disk Mirroring RAID 5+1 - Mirrored RAID 5 MirrorDisk no fresh mirror

Any help would be appreciated.

Re: Question about Mirror/UX

Do you have two disks in vg00? You should specify the PV with the lvextend command to indicate where to mirror lvol1.

vgdisplay -v /dev/vg00

Re: Question about Mirror/UX

Hi

If you do a plain "swlist", do you see the following bundles (or something like these):


B2491BA B.11.31 MirrorDisk/UX (Server)

Base-VXFS B.11.31 Base VxFS File System 4.1 Bundle

for HP-UX

BaseLVM B.11.31.0909 Logical Volume Manager

All the best

Re: Question about Mirror/UX

How about trying using "smh" or SAM to mirror you logical volume

SMH -> f - Disks and File Systems-> l - Logical Volumes View or Manage Logical Volumes

Re: Question about Mirror/UX

I doubt , you have mirror ux installed?

Check mirror ux

# swlist -l fileset |grep -i mir

LVM.LVM-MIRROR-RUN B.11.23 LVM Mirror

Re: Question about Mirror/UX

I am pretty sure that you dont have mirror software installed on it . on 11.31 output should be like as follows


LVM-MirrorDisk.LVM-MIRROR B.11.31 HP-UX sup
port for the MirrorDisk/UX

and also -m will disable if you dont have mirror software installed on the system and this is only error what you are getting

Re: Question about Mirror/UX

Shalom,

Mirror-UX needs the Physical volum path you wish to mirror to. Always do your homework and set that path. Letting it decide, will lead to bad results.

This is a simple matter of not following basic command syntax.

lvextend -m 1 /dev/vg01/lvol1 /dev/dsk/c1t0d0

That is good syntax.

>>basic command syntax.

No, it isn't. It is a matter of 'lvextend' not being aware of the '-m' option. It plainly says '"m": Illegal option.' If you notice the 'usage' statement it says nothing about the '-m' option.

It appears, as others have basically said, that Mirror/UX is not installed. Or maybe more accurately not COMPLETELY installed for some reason.

I would reinstall Mirror/UX at your first opportunity. I don't recall if it requires a reboot or not.

>>lvextend -m 1 /dev/vg01/lvol1 /dev/dsk/c1t0d0
>>That is good syntax.

That is true.

Re: Question about Mirror/UX

Hi:

I'm in agreement with Patrick. You might try running a full 'swverify' to make sure that everything is in the state you think it is;

# swverify \*

swlist -l fileset -a state |grep -v -e "#" -e "configured"

please run the above command & provide the output. Mirror disk may not installed properly.

Re: Question about Mirror/UX

Hello,

Please check whether you had the Mirror UX software installed in your system. I assumes it is not there.

#swlist | grep -i mirror

and check with that.

If there is no Mirror UX , you have to install and reboot the server for building the new kernel and the mirroring.

Best of Luck

Re: Question about Mirror/UX

If I run:

swlist -l product | grep -i mirr

Nothing shows up.

But look at this. Does that mean I have mirror-ux installed? This is 11.23.


#: swlist -l fileset |grep -i mir
LVM.LVM-MIRROR-RUN B.11.23 LVM Mirror

Re: Question about Mirror/UX

hi S-un-B-ix-S ,

Like all i am also doubtou full that you are installed Mirror/UX properly,
Jest check it by
#swlist -l bundle
Mirror UX will come in the top. If it is installed properly then you can mirrored it by using #lvextend -m 1 (option), with out installing Mirror ux properly then you will not get -m option from lvextend,

Please confirm your first disk device file..


thanks,
