VPAR start/stop

[Shakeer_1]

I have a SD3200 server, partitioning is as follows
1) nPar 0
a. vpar 0
b. vpar 1
2) nPar 1
a. vpar 0
b. vpar 1
All these VPARS are connected to the SAN. We have a SAN upgrade activity. I need to bring down (shutdown)all the VPARS to perform the SAN activity, once the SAN acvity is over i need to start the VPARS again. Can anybody provide me with the detail procedure to start/stop the VPARS within the nPars. Also are there any considerations like start/stop sequence?
Thanks in advance

On each Vpar, simply shutdown -h 0

On your Console for each Npar you should then be left with the MON> prompt.
You can then restart the Vpars by doing
vparload -all

or reset the Npar and provided all the autobot strings are set correctgly they should autoboot

[IT_2007]

run parstatus -Vp 0 and parstatus -Vp 1 which will show primary, alternate and high available boot paths. Make sure that those are poing to your boot disk.

Primary Boot Path : 0/0/0/2/0.6.0
Alternate Boot Path : 0/0/0/3/0.6.0
HA Alternate Boot Path : 1/0/0/3/0.6.0

Because if you reset Npar then it may boot as Npar instead of Vpar if boot strings are not correct. You can check boot strings on boot disks for all Vpars.

lifcp /dev/dsk/cXtYdZ:AUTO -

should show like

hpux -lq /stand/vpmon -a

otherwise you can run this command

mkboot -a "hpux -lq /stand/vpmon -a" /dev/dsk/cXtYdZ

Hi ,
Simply login to the each Vpar as root as do normal shutdown as if your doing in non vpar servers. Ensure your applications are properly shutdowned.

For bring up the server,
1. login to the GSP console.
2. Go to cm prompt. run rs for npar 0 and npar 1.
3. both the npar will comes up with default primary vpar.
4. start the other vapr using vparboot command by Login to the both npars one by one by using GSP co command from GSP main menu.
GSP>cm
CM>rs --> nPar0
CM>rs --> nPar1
CM>ma --> to bring to main menu
GSP>VFP ->check both npar till cells comes to hearbeat.
GSP> co ->login to console of both npar and boot the other partition

if you are in VPMON prompt you can boot all vpars by " vparload -all" command

Thanks and regards

vparstatus on on vPar in each nPar to sync vPar database

shutdown -h -y now on each vPar

to boot from vpmon
vparboot -all
