Hardware migration from rp3410 to rp3440

Sunny Jaisinghani — Thu, 18 Jun 2009 05:18:17 GMT

Hello Gurus,

we had planned a migration of a production server from the rp3410 model to rp3440 model.

We had planned to connect the hard drives from the rp3410 model (supporting max 8GB memory) to the new rp3440 model (max memory 16GB) and boot the server.

While booting the boot process hung up. see logs below.

Initialization finished successfully... slot is 9
Logical volume 64, 0x3 configured as ROOT
Logical volume 64, 0x2 configured as SWAP
Logical volume 64, 0x2 configured as DUMP
Swap device table: (start & size given in 512-byte blocks)

Then process stops with no error and stays at this point for more than 30 minutes.
Since this was going nowhere we planned to revert to rp3410.

Has anyone accomplished such kind of task.
Is there a better way to do this.

1 other way which we havn't tried but have planned to do it on some weekend is to push the ignite of OS running on rp3410 to new rp3440. Both would be ignite clients.

Please let me know if this would be feasible and the way to go about it

Tha last option would be to install a fresh copy of OS on the new hardware

Thanks in advance

Sunny

Hi,

Are you able to login into rp3440 server if not then did you try to boot in single user then check the syslog.log file.
if yes then also check the syslog.log is there any error you have found ?

Hi Sunny,

Did you try to boot in different runlevels?
and did you try to TOC and analyz the log ?..
check MP logs as well ..

The only difference between these two systems is the number of slots and the number of processors - so I would think it should work without problems - unless there is a hardware problem. Inspect the MP logs or consider to try the ignite restore.

Make sure you put the disks in the same slots.

If you install all 3 disks, check if you have something connected to the external built-in SCSI port - this may cause trouble.

No. I did not try to boot in single user mode or any specific runlevels.

We would definately try these things when we ge the production down.

I would like to have as many options as possible before we start trying out these options.

Thanks

Will this option work for me.

Create a golden image of OS on rp3410 and store it on Ignite UX server.

Push the golden image from the ignite UX server to the rp3440 machine.

Is there a documentation which i can refer to?

Thanks

hi

on the running rp3410 make a note of the boot disks in the root VG vg00.

you can get that by vgdisplay -v vg00
note those down.
also

lvlnboot -v

note the O/P

setboot

note the settings.

shutdown that and removing the local disks put in the same slot positions identically in rp3440.

as i think you have an ignite tape backup ready , do have it ready , it is very helpful, but i shall before trying that ask you to give a try to boot the rp3440 putting the disks from rp3410 in the same order of the slots.

then boot in the LVM maint mode.

BCH> search
select path to boot
BCH> boot that is path that teh search O/P shows as the boot disk.

Interrupt by pressing any key to interact with IPL, abortibng autoboot. interact with IPL? (y/n)? y

ISL> hpux -lm

once booted export and reimport the root VG.

#vgexport vg00
#mkdir /dev/vg00
#mknod /dev/vg00/group c 64 0x000000
#ioscan -fnCdisk

note and compare the discovered disks.
#vgimport /dev/vg00 /dev/dsk/cxtydz /dev/dsk/cXtYdZ
#lvlnboot -b /dev/vg00/lvol1
#lvlnboot -s /dev/vg00/lvol2
#lvlnboot -r /dev/vg00/lvol3
#lvlnboot -d /dev/vg00/lvol2
#lvlnboot -v
#vgchange -a y vg00
#vgcfbackup vg00
#vgdisplay -v vg00
#setboot -p -a -b on -s on
if all is OK.
reboot normally,

#shutdown -ry 00
