rp2470 ignite restore problem

Mikikiki — Thu, 17 Nov 2011 16:05:36 GMT

Hi all,

We have hp rp2470 server running hp-ux 11.00, with LVM mirroring. As for redundancy we have second rp2470 same hw (same two processors, same ram, same two hdd’s, same number of lan cards).

I want to clone first one to the second. For that purpose I am making ignite tape with the following command: make_tape_recovery -x inc_entire=vg00

Ignite tape finishes without problems. When I boot second server from this ignate tape, server is starting to boot, and ignite restore finishes without any errors, only few notes, which are normal.

However vmunix is not booting and when restore finishes, it boot to ISL> prompt.

From this I cannot boot /stand/vmunix.

I tried to run recovery shell but no success. When recovery shell ask to do frecover to restore critical files, then I receive error: frecover(5405): unable to open /dev/rmt/0m

I will appreciate any help.

Regards,

Attempt to create another make_tape_recovery archive with -I (interactive) option:

# make_tape_recovery -I -x inc_entire=vg00

This will force you to interact when you do the recovery on the other system.

Modify hostname, IP address, LVM filesystem size per your needs.

Although you mentioned everything is identical, when you do the recovery, go in to the "Basic" tab, and under "Additional", select "cloning to different HW?" (Set it to true). The system will generate a new kernel from the /stand/system file that was created from the archive, and not simply use what was on /stand/vmunix.

Hello Henry,

Thank you for your reply.

Can you be more specific when you mention: "go in to the "Basic" tab, and under "Additional", select "cloning to different HW?" (Set it to true). "

Where I can find this basic and additional tabs? Will I have that option after when using "I" option when creating the archive tape?

Did you start "hpux" from there?

Re: rp2470 ignite restore problem

Mikikiki — Fri, 18 Nov 2011 09:01:52 GMT

I tried but no success.

All the time when I put hpux it wait for a few seconds and again goes to ISL> prompt.

I also tried hpux with -q and -lq because production server uses lvm mirroring but again same isl prompt.

Please do

ISL> hpux ls -l

to list the files in /stand.

Hi Torsten,

I tried with command you suggested, but again nothing to display.

This is output:

ISL> hpux ls -l

ISL>

Do you have anything in mind why this is happening?

Hmmm, I would try with a newer firmware: http://h20000.www2.hp.com/bizsupport/TechSupport/SoftwareDescription.jsp?lang=en&cc=us&prodTypeId=15351&prodSeriesId=2511789&swItem=PF-CHAW4350&prodNameId=86730&swEnvOID=7&swLang=13&taskId=135&mode=4&idx=0

Hi,

Newer firmware on the production server is not an option. It is business critical server so I can not play so much with it.

Is it maybe possible to start recovery shell to try to rebuild kernel or critical files?

If so, I will need help to do this, because as I mentioned I already tried but couldn't find helpful manual for this.

What is the firmware of the other server? Well, this "new" version is from 2006 - so there is no risk!

There are many boot related fixes between your version and the current version.

Hi Torsten,

I can't do any restarts on the production server.

Firmware Revision C.02.14 Apr 14 2003, this is on production server.

This is the revision of the GSP, not the server. Run STM to get the PDC version, e.g.:

# echo "sel dev all;info;wait;il"|cstm|grep -i pdc

Not even on the broken server, the one you are trying to restore?

Hello,

On the second server ofcourse I can do firmware upgrade because it is not usable at this moment. But I think it has newer fw version. From boot log I could see this: Firmware Version 42.19.

Re: rp2470 ignite restore problem

Mikikiki — Fri, 18 Nov 2011 15:25:11 GMT

Hi Torsten,

fw version of production server is: Firmware Version 43.50

and fw version of backup server is: Firmware Version 42.19

so probably my production server has newer firmware. I can do fw upgrade on backup. I will see if I can do it from this point from gsp or from isl and come back then.

Br,
Yes, after you create the archive with the -I option, and then when you boot from the tape, you will see the Menu with all the tabs I was referring to.

Henry,

thank you for your reply.

I will try first fw upgrade because there is fw difference between those two servers and after that try restore with -I flag.

After that I will send you feedback.

Best regards,

Dear All

I did fw upgrade so now both servers have fw version 43.50. After this I tried recovery but again cant boot the system.

Next I did archive tape with -I flag as Henry suggested, and tried recovery with it, again no good.

I cannot find any error or warnings on ignite log, but cannot boot hpux. I am only on ISL> prompt.

However on gsp log I noticed this:

************* SYSTEM ALERT **************
SYSTEM NAME: mcnfwim1

Can this be the root of a problem?

Any help is appreciated.
