Question about Mirror/UX

[S-un-B-ix-S]

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.

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

[S-un-B-ix-S]

Yes, there are 2 physical disks in vg00.

--- Volume groups ---
VG Name /dev/vg00
VG Write Access read/write
VG Status available
Max LV 255
Cur LV 8
Open LV 8
Max PV 16
Cur PV 2
Act PV 2
Max PE per PV 4356
VGDA 4
PE Size (Mbytes) 32
Total PE 8694
Alloc PE 3962
Free PE 4732
Total PVG 0
Total Spare PVs 0
Total Spare PVs in use 0

....


--- Physical volumes ---
PV Name /dev/disk/disk616_p2
PV Status available
Total PE 4347
Free PE 385
Autoswitch On

PV Name /dev/dsk/c2t6d0s2

:root:/opt/uniq->lvextend -m 1 /dev/vg00/lvol1 /dev/dsk/c2t6d0s2

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

[Johnson Punniyalingam]

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

[johnsonpk]

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



rgds!

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

[Steven E. Protter]

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.

always follow official documents from HP as mentioned below

>>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.

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 \*

Hi,

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

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

[AVV]

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

[dictum9]

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
PHCO_34036.LVM-MIRROR-RUN 1.0 LVM.LVM-MIRROR-RUN

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,

[Prasanth Thomas]

HI,

Please let me know is this issue resolved???

If not please share me the o/p f below command

# ioscan -m dsf
# strings /etc/lvmtab
#ls -ltr /dev/disk/*


Regards,
Prasanth Thomas.

[Prasanth Thomas]

i am suspecting this issue with your second disk device file. You did not extend the VG properly for that please share the o/p which i have requested you earlier.

Regards,
PT.
