pvdisplay: Couldn't find the volume group to which
physical volume "/dev/dsk/c0t10d0" belongs.

please advise

thanks

You can only do a pvdisplay on a pv that is part of a VG.

When you do a pvcreate and get that error, you need to add the '-f' flag to force the pvcreate.

# pvcreate -f -B /dev/rdsk/c0t10d0

Thanks for that.

I am trying to mirror the boot disk.

I did the pvcreate, vgextedn, mkboot and the commands ran fine.

Now I am trying to use the lvextend command
10.200.210.55:0-visadr-root $ lvextend -m 1 /dev/vg00/lvol1 /dev/dsk/c1t4d0
Usage: lvextend
[-A Autobackup]
{-l LogicalExtentsNumber |
-L LogicalVolumeSize}
LogicalVolumePath [ PhysicalVolumePath... | PhysicalVolumeGroupName... ]
"m": Illegal option.

Why is m illegal??? I cant understand.

Also right now

10.200.210.55:0-visadr-root $ lvlnboot -v /dev/vg00
Boot Definitions for Volume Group /dev/vg00:
Physical Volumes belonging in Root Volume Group:
/dev/dsk/c1t4d0 (56/52.4.0) -- Boot Disk
/dev/dsk/c1t6d0 (56/52.6.0) -- Boot Disk
Boot: lvol1 on: /dev/dsk/c1t4d0
Root: lvol3 on: /dev/dsk/c1t4d0
Swap: lvol2 on: /dev/dsk/c1t4d0
Dump: lvol2 on: /dev/dsk/c1t4d0, 0


/dev/dsk/c1t4d0 is the newly added disk and /dev/dsk/c1t6d0 is the existing boot disk.


why is it showing /dev/dsk/c1t4d0 when I have yet to mirror the logical volumes.

thanks for your response.

swlist | grep Mirror

does not return anything. I guess thats where the problem is.

Now this is a test system and I am trying to test the disk mirroring process. We do have Mirroring in the production server.

Can i install the mirror module on the test box and get it to work for testing purposes.?
thanks

[Patrick Wallek]

MirrorDisk/UX must be licensed in order to install it. Without MirrorDisk the '-m' option to lvextend will not be available to you.

Your new disk is showing up in lvlnboot because you have done the pvcreate -B and the mkboot commands on the disk.

[golfnut]

Thanks for your input.

I do have the HP-UX 11.0 Application Software CD's 1 through 5. Its dated dec 2000. I also have the codeword.

Can i use this?

If so, how? which CD will have the mirroring module?

thanks

[Patrick Wallek]

MirrorDisk is on Applications CD #1.

You invoke swinstall, point it to the CD, go to one of the menu's in swinstall (I forget which one) and enter the codeword information. After that the MirrorDisk software will be displayed.

You can then mark it and install. Note that the installation will REQUIRE a reboot as it rebuilds the kernel.

[Albert Smith_1]

Are you running 10.20 or 11.0 or 11i.

You need to install the version applicable for your versioin of the OS. And it does require a kernel change and a reboot. If you have OnLine JFS I would add that as well.

10.200.210.55:0-visadr-root $ uname -a
HP-UX visadr B.11.00 A 9000/816 906338271 two-user license


The CD is dated dec 2000. Will that be fine.

thanks

please advise.

Check the output of

# nslookup hostname

# nslookup ipaddress_hostname

[Kent Ostby]

On your original question, when re-using a disk, I'll dd a file over the front of the rdsk so that the old data wont be looked at then redo the pvcreate etc. I know you're past that now, but just to note that.

On the latest error,

check "ifconfig lan0" versus what is in /etc/hosts.

Sometimes a mismatch here causes that problem.

[golfnut]

thanks guys.
that worked
