how to make the disk bootable?

[praveen..]

Hi,
PV status of one disk under vg00 was unavailable.
so i replaced the disk.

and after booting the server,
1. vgcfgrestore -n /dev/vg00 /dev/rdsk/c3t6d0
2. vgchange -a y /dev/vg00
3. vgsync vg00
4. mkboot /dev/rdsk/c2t6d0 (makes it bootable)

then I am getting this error:

# mkboot /dev/rdsk/c3t6d0
There appear to be non-boot logical volumes on this device.
Overwriting them could destroy all the data on this device
Should the logical volumes be overwritten [y/n]? n

I typed "n" and made it exit?

should i proceed it using "y"?
will i losse the data, this is my production server and this disk is under vg00.

please suggest what to do?

Hi parveen

Your procedure was wrong.
First you should do pvcreate -B and then should vgcfgrestore.

1. pvcreate -B /dev/rdsk/cXtYdZ
2. mkboot -l /dev/rdsk/cXtYdZ
3. vgcfgrestore

Hi Praveen,

Your steps are correct according to the OLR (Online Disk Replacement). Check if you have next patches installed on your system.

The LVM OLR feature is enabled with the following patches:

HP-UX 11.11:
PHKL_31216 s700_800 11.11 LVM Cumulative Patch; LVM OLR; SLVM 16 Node
PHCO_30698 s700_800 11.11 LVM commands cumulative patch; LVM OLR

HP-UX 11.23:
PHKL_32095 s700_800 11.23 LVM Cumulative Patch; OLdR enablement
PHCO_31709 s700_800 11.23 LVM commands patch

Note: Apply these patches and any required dependencies. These patches, as with any patch, may be superseded. Please check for the latest patches at HP's IT Resource Center (ITRC) at the following web site:

please let me know what should i do now?
how to make it bootable?

Thanks

lvlnboot -r /dev/vg00/lvol3 # root fs /
lvlnboot -s /dev/vg00/lvol2 #swap

lvlnboot -b /dev/vg00/lvol1

Post the output of lvlnboot -v
Did you do pvcreate -B ??

Regrads
nanan

[praveen..]

No, I did not do pvcreate.

and after booting the server, i did only..
1. vgcfgrestore -n /dev/vg00 /dev/rdsk/c3t6d0
2. vgchange -a y /dev/vg00
3. vgsync vg00
4. mkboot /dev/rdsk/c2t6d0 (makes it bootable)

then I am getting this error:

# mkboot /dev/rdsk/c3t6d0
There appear to be non-boot logical volumes on this device.
Overwriting them could destroy all the data on this device
Should the logical volumes be overwritten [y/n]? n

I typed "n" and made it exit?

should i proceed it using "y"?
will i losse the data, this is my production server and this disk is under vg00.

please suggest what to do?
how to make this disk bootable?

[nanan]

You should do that command before do vgcfgrestore

You have to do again

The first Remove the pv from vg00

vgreduce vg00 /dev/dsk/c3t6d0

and then start from pvcreate -B


good luck

[nanan]

Praveen !
I missed one
before do vgreduce
do lvreduce -m 0

Sorry

[praveen..]

please check volume group vg00 configuration which i posted above.

so now should i give these commands:
1. vgreduce /dev/vg00 /dev/dsk/c3t6d0
2. pvcreate -B /dev/rdsk/c3t6d0
or #pvcreate -Bf /dev/rdsk/c3t6d0
3. vgcfgrestore -n /dev/vg00 /dev/rdsk/c3t6d0
4. vgchange -a y /dev/vg00
5. vgsync vg00
6. mkboot -l /dev/rdsk/c3t6d0
7. mkboot -a "hpux -lq (;0)/stand/vmunix" /dev/rdsk/c3t6d0
8. lvlnboot -Rv

or should i use these commands:

1. vgreduce /dev/vg00 /dev/dsk/c3t6d0
2. pvcreate -B /dev/rdsk/c3t6d0
or #pvcreate -Bf /dev/rdsk/c3t6d0
3. vgcfgrestore -n /dev/vg00 /dev/rdsk/c3t6d0
4. vgchange -a y /dev/vg00
5. vgsync vg00
6. mkboot -l /dev/rdsk/c3t6d0
7. mkboot -a "hpux -lq (;0)/stand/vmunix" /dev/rdsk/c3t6d0
8. lvlnboot -r /dev/vg00/lvol3 /dev/vg00
9. lvlnboot -b /dev/vg00/lvol1 /dev/vg00
10. lvlnboot -s /dev/vg00/lvol2 /dev/vg00
11. lvlnboot -d /dev/vg00/lvol2 /dev/vg00
12. lvlnboot -R
13. lvlnboot -v

at present, my system is in multi user mode, should i give these commands in multi user mode

or should i boot the server into LVM Maintenance Mode, if yes, how can i ?

server is very far from physically.

Thanks

[nanan]

At the most you have to lvreduce as i stated
and then
choose secand one you posted above.

you can do this multi-mode don't worry

good luck!!

[nanan]

At the most you have to lvreduce as i stated
and then
choose second one you posted above.

you can do this multi-mode don't worry

good luck!!

[praveen..]

which logical volume should i reduce?

please tell me the full command.

these disks are mirrored to first disk, i think no need to reduce the LV.

[praveen..]

does it will effect on LV size/confoguration or not?

this is production and running server..

[nanan]

No, just split the mirror copy disk(c3t6d0)

[praveen..]

I gave these commands:

lvreduce -m 0 /dev/vg00/lvol1 /dev/dsk/c3t6d0

and when i give this command:
# vgcfgrestore -n /dev/vg00 /dev/rdsk/c3t6d0
Configuration info for Physical Volume "/dev/rdsk/c3t6d0" not found
in "/etc/lvmconf/vg00.conf" :
Character-special file for PV not supplied on command line, OR
PV did not belong to Volume Group /dev/vg00 when configuration file was created.


what should i do?

[nanan]

Praveen!
Good job. until now
It is no wonder you got the mesages because you remove the device name from lvmtab and your vgcfgbackup file no more containing the device on vg00.
Now, Let's start mirror OS

1. pvcreate -Bf/dev/rdsk/c3t6d0
2. vgextend vg00 /dev/dsk/c3t6d0
3. lvextend
all of the lvols
lvreduce -m 1 /dev/vg00/lvol1 /dev/dsk/c3t6d0
lvreduce -m 1 /dev/vg00/lvol2 /dev/dsk/c3t6d0
lvreduce -m 1 /dev/vg00/lvol3 /dev/dsk/c3t6d0
lvreduce -m 1 /dev/vg00/lvol4 /dev/dsk/c3t6d0
lvreduce -m 1 /dev/vg00/lvol5 /dev/dsk/c3t6d0
lvreduce -m 1 /dev/vg00/lvol6 /dev/dsk/c3t6d0
lvreduce -m 1 /dev/vg00/lvol7 /dev/dsk/c3t6d0
lvreduce -m 1 /dev/vg00/lvol8 /dev/dsk/c3t6d0
lvreduce -m 1 /dev/vg00/lvol9 /dev/dsk/c3t6d0
lvreduce -m 1 /dev/vg00/oracle /dev/dsk/c3t6d0
lvreduce -m 1 /dev/vg00/ora /dev/dsk/c3t6d0
lvreduce -m 1 /dev/vg00/laoracle /dev/dsk/c3t6d0
lvreduce -m 1 /dev/vg00/home /dev/dsk/c3t6d0

As you know these command is syncing for mirror volume.
it will take so long time depend on the disk size.

You can confirm whether or not that is normal with lvdisplay -v /dev/vg00/lvol1

After finish this. do lvlnboot you stated
and mkboot -l

is this problem due to "first i extend lvol6 size" or not?

Never, lvol2 is swap insn't it?
