Notice: Allocation PVG-strict !

What was your command? Does it match the PVG configuration?

[Kusado]

I'm trying ro mirror the volume whith
lvextend -m 1 /dev/vg00/lvol1 /dev/dsk/c1t2d0
Other LV's are not using PVG-strict policy, but aren't mirroring with same error message...

[Johnson Punniyalingam]

strings /etc/lvmtab -> output would you helpfull

and how did you extended the "vg00" ?

[Johnson Punniyalingam]

I just came acroos this link,

I hope you Orginal disk size and mirror disk size larger.

Check below link for more information

Hope this Helps.

[Kusado]

vg00 was extended with

pvcreate -B /dev/rdsk/c1t2d0
vgextend /dev/vg00 /dev/dsk/c1t2d0

[Johnson Punniyalingam]

strings /etc/lvmtab

can you post above output of the command

[Torsten.]

post

/etc/lvmpvg

too!

[Torsten. · Accepted solution]

You need to adjust this

/etc/lvmpvg:


VG /dev/vg00
PVG PVG1
/dev/dsk/c4t8d0
PVG PVG2
/dev/dsk/c1t2d0

Then do

lvextend -m 1 /dev/vg00/lvol1 PVG2

[Kusado]

root@gcu_its [/]#lvextend -m 1 /dev/vg00/lvol1 PVG2
The newly allocated mirrors are now being synchronized. This operation will
take some time. Please wait ....
Logical volume "/dev/vg00/lvol1" has been successfully extended.
Volume Group configuration for /dev/vg00 has been saved in /etc/lvmconf/vg00.conf

root@gcu_its [/]#vgdisplay -v /dev/vg00/lvol1
vgdisplay: Volume group "/dev/vg00/lvol1" does not exist in the "/etc/lvmtab" file.
vgdisplay: Cannot display volume group "/dev/vg00/lvol1".


I wonder if it's normal that i can't see lvol1 config...

[sujit kumar singh]

hi

use vgdisplay -v vg00
and .or
lvdisplay -v /dev/vg00/lvol1

regards
sujit

[Torsten.]

As said, wrong command:

vgdisplay -v /dev/vg00/lvol1

VG(display) vs. LVOL1

;-))

[Kusado]

sujit:
thx )
Didn't catch my mistake by my self )))

2all:
What steps do I have to take to be able boot/use this disk if c4t8d0 fails?

I'm mirroring other LVs to new disk now.
Then i'm gonna execute
"
mkboot /dev/rdsk/cxtydz
mkboot -a "hpux" /dev/rdsk/cxtydz
lvlnboot -R
"
as the HotSwapSoftwareProcedure says.

[Torsten.]

I hope you know

http://docs.hp.com/en/5991-1236/When_Good_Disks_Go_Bad_WP.pdf

see the appendix!

[sujit kumar singh]

Hi


As per the when_good_disks_go"_bad_APPENDIX as said by torsten,


please do not forget to update the /stand/bootconf with adding the line.
if that is already there, you can leave that as such.
l /


lvlnboot -R
lvlnboot -b
setboot -a

regards
sujit

[sujit kumar singh]

Hi


no points for duplicate post please


lvlnboot -b

in earlier posts should read as

lvlnboot -v


regards
sujit

[Kusado]

So, check me plz )
I'm finishing creating mirrors
(lvextend -m 1 /dev/lvolX PVG2)

then making disk bootable with
mkboot /dev/rdsk/c1t2d0
mkboot -a "hpux" /dev/rdsk/c1t2d0

then I should check /stand/bootconf

then running

lvlnboot -R

Am I right?

[Torsten.]

According to the manual (Appendix D) it is mkboot -l ... - please check this again. Don't forget to set the path in NVRAM!

[Kusado]

That's what I have now:

#How many disk have to be listed here? Just one of mirror holders or both?

[sujit kumar singh]

Hi

add both of them.

regards
sujit

[Torsten.]

Normally both.


"...
This file, /stand/bootfonf, contains the address and disk layout type of the system's boot devices or lif volumes. It is used by the Software Distributor and HP-UX kernel control scripts (fileset OS-Core.KERN-RUN) to determine how and where to update the initial boot loader. Normally the kernel's checkinstall script queries the system's hardware and creates the file. In rare cases when either the system configuration cannot be automatically determined or additional and/or alternate boot devices should be automatically updated, the administrator must edit the /stand/bootconf file manually.

..."


http://docs.hp.com/en/B3921-60631/bootconf.4.html

[Kusado]

So.
I've mirrored all volumes
I've mkboot â e â l /dev/rdsk/c1t2d0
I've added both disks to /stand/bootconf
I've lvlnboot -R

Anything else? Or I'm able to forget bout this nightmare for a while?

[sujit kumar singh]

hi


did you do setboot to set the alternate boot path as well as autoboot on?

setboot -a -b on
