VPAR : second vpar reboot causes first vpar rebooting.

[Arun B S Nair]

Hi Gurus,
I have a rp8420 server having one npar running two vpars. ( HPUX 11.11 , Vpar A.03.03.06 , PDC 23.1 , STM 47.15 )
This npar is having two single core cells and a total 8 cpus. Each vpar configured with 4 cpu each( one cell board each ). A reboot of Vpar1 is not causing any problem to Vpar2.But when I reboot vpar2 , it resets vpar1 also.
( no updates in shutdown log or syslog of vpar1 for this ). In VFP, during this reboot I can see the partition status as "halted" for a while. Any thoughts ... Many Thanks in advance

can you also post vparstatus output without -v options.

SO you are simply executing shutdown -r -y now on aded119p and nothing else ?

No , no RS ?

I have a couple similarly configured rp7420's with no issues during reboots from either server.

[IT_2007]

Looks good and no problem in output. Only thing is if you don't see any errors in syslog on both vpars, my suggestion is look at GSP chasis log. It may give you some idea. If you still stuck at that point, time to call HP.

[Arun B S Nair]

Yes I am issuing only shutdown -r -y 0

[IT_2007]

also would you please check size and permissions for /stand/vpdb and vpmon files on both servers? Please post results.

[Joël Techer]

Hi,

I suggest you to do vparextract -l command that will be very interesting for you => VPMON log
so you will be able to detect the pb

Has the vpars newly created?

Best regards

[Arun B S Nair]

both servers are having vpdb and vpmon of same size. vparextract -l is not giving anymore insight to the issue.

Another observation is that,
a shutdown -h -y 0 of any of these partitions funcions properly and doesn't reboot the other one ..

I would suggest you to check the firmware level, there have been issues if the firmware doesn't match the minimum vpar version criteria:

Please refer the following link for the same ( look at page 12):
