Installation,LVM issue in R-class-HP UX 10.x

[Abdul Ahad.H]

Dear All,

I am facing the following problem.Hope I can get some good inputs to sort this out.




Currently the m/c is a R-Class server with 128 MB
RAM and HP-UX 10.20 loaded the following is the
lvlnboot output
# lvlnboot -v
Boot Definitions for Volume Group /dev/vg00:
Physical Volumes belonging in Root Volume Group:
/dev/dsk/c0t6d0 (8/16/5.6.0) -- Boot Disk
/dev/dsk/c0t5d0 (8/16/5.5.0) -- Boot Disk
Boot: lvol1 on: /dev/dsk/c0t6d0
/dev/dsk/c0t5d0
Root: lvol3 on: /dev/dsk/c0t6d0
/dev/dsk/c0t5d0
Swap: lvol2 on: /dev/dsk/c0t6d0
Dump: lvol2 on: /dev/dsk/c0t5d0, 0

the swap size what i configured is 512 MB in
/dev/dsk/c0t6d0 this is a 18GB disk.

I am putting here what I did in this server

Loaded Os in the 18 gb disk /dev/dsk/c0t6d0
then mirror ux is loaded and then the second disk is
configured as a boot disk /dev/dsk/c0t5d0 this is a
9 gb disk.after mirroring the disks root partitions

1-lvlnboot -b /dev/vg00/lvol1 for stand volume
2-lvlnboot -s /dev/vg00/lvol2 for swap volume
it gave the following error

# lvlnboot -s /dev/vg00/lvol2
lvlnboot: Unable to configure swap logical volume.
Swap logical volume size beyond the IODC max
address.
then i tried for the same error in net i didnt get any
output so i forwaded for the root volume lvln updation
it went smoothly.


I tried reducing the swap space to 256 MB and tried
the same once again i got the same error .


Now I booted the M/C with the second disk it is
using the swap space of the first disk so it means if
the primary disk fails the m/c is not going to boot.

Earlier this M/c was loaded with 11.0 will the
version change will give any problem.


Waiting for reply

You must have primary swap on *all* disks you intend to use to boot from, no exceptions. The system needs swap to actually boot the system properly and then allow programs to start. Without swap no programs can actually start much less the system starting itself. Suggest you boot from your primary disk, trash the mirroring and redo it and include lvol2 which has the swap.

hi,
pls check that the patch PHCO_24809 is installed on your system.due to this patch this problem can occure.
the patches for solving this problem & the problem which it will solve is given below.

PHCO_25390:
( SR:8606220106 CR:JAGad89247 )
PHCO_24809 introduced behavior that will cause the
lvlnboot(1M) command to fail when executed in recovery
mode. Executing 'lvlnboot -R' will fail to configure swap
and dump volumes and messages similar to the following will
be reported:
lvlnboot: Unable to configure swap logical volume.
Swap logical volume size beyond the IODC max address.
lvlnboot: Unable to configure dump logical volume.
Dump logical volume size beyond the IODC max address

hi,

for 10.20 hpux in the site it is showing one more patch.but it is for series 700.


PHKL_15492:
The command: lvlnboot -d returns with the
message:
Unable to configure dump logical volume.
Dump logical volume file beyond the IODC max address
whenever any part of the given lies beyond 2G bytes
from the start of a PCI-SCSI disk.

and the superceded patch is PHKL_16750

check any part of the given lies beyond 2G bytes.

Dear all,


First of all thanks everyone who immediately posted replies.

My problem is still not solved.


Today we remirrored the second disk once again from
scratch.in the said order
lvol1
lvol2
lvol3
lvol4
lvol5
lvol6
lvol7

But issue is when we updated the lvlnboot for the
second lvol it gave the same old error and it didn't
passed out.

we have a test server over here so we have loaded
Os and followed same steps to mirror the root
partitions this is a D-Class server.

We didnt faced any problem on this and regarding
the patch the patch ios missing on both the servers
and OS is same.

Is it possible that the root disk of my R-class
server got some problem.

Dear all

I didn't see more assistance after the initial response when I posted again the results.
anyway.......

Thanks for the valuable input for my query.
Today we replaced the 18 gb Primary disk and then
mirrored the 9 gb scsi disk.It got mirrored without
any problem and we havent used any patches as per the
technical discussions with one of my friends in HP
First they requested us to upgrade the firmware
version of both the disks.Which didnt worked.
Latter they say the 18 gb in which primary disk
swap space of 512 MB what we created might be having
some unusable area so it may give this kind of problem

Once after replaceing the disk and loaded OS we
mirrored the second disk as earlier it got mirrored
without any problem.

Now there is no problem in the mirroring i tried
boting with the second disk indivudually it works
fine.


Thanks again for all those who tried their best to guide me.
