Hi,

If the cluster is configured properly,
#> cmruncl
and
#> cmhaltcl -f

do exactly what you need. Could you please be more precse ?

I wanted the sequence of shutdown of VA & Cluster including command.Because before this I have never done this.This is first time I am shuting down the cluster & VA.
thanks.

The first, System shutdown for this
you have to follow these steps

1. Application shutdown
If yr system appliction is using cluster volumes

2. cluster halt
- cmhaltpakg
- cmhaltnode
both of above commands colud be canceled
depand on your system environments
- cmhaltcl -f

3. After finish cluster halt normally,
shutdown system

4. Finally, you can shutdown VA array
Just moving the power/stand by switch to standby position.

that's it

Shalom,

Shut the software in the cluster as Victor directed.

Shut the system down next if needed.

Then shut the VA7410.

You always shut storage last, because the system may have a process open trying to write to it.

On the way back up you turn on the storage first, give it enough time to get to a normal running state and only then start the systems. Depending on cluster configuration it is normally irrelavent which node you start first.

thanks nanan & steven.
My procedure is ,

Stop the application
do cmhaltcl -f (which will down packages)
on node1- shutdown -h 0
on node 2-shutdown -h 0
power off bothe nodes

Now for va7410 Can I dirctly switch off the power of both controllers (because I can't use armmgr since system is down

Sowith off JBOD directly.

For Restart
Jbod,VA controller,Node1 & Node 2 then cmruncl
thanks

[Steven E. Protter]

Yes, note that cmhaltcl -f shuts down both nodes from one command.

We HP-UX geeks like that.

Glad it all worked out with you.

Hi,

If you want to start up/stop the cluster automatically, edit /etc/rc.config.d/cmcluster file and set AUTOSTART_CMCLD=1 .

BTW, why do you need to stop cluster and switch off the HW ? It must work 7x24, 365 days.

Good Luck

Dear all
My question was is this sequence OK.
Also one more thing,After swithching off Cluster node1 & node 2, Can I directly swith off Va7410 & Jbod or Before shutting nodes I have to shutdown Va using armcfg -s
thanks in advance.

sorry the command for Va shutdown armmgr

No you better shutdown servers then switch off VA.

[V.Manoharan]

Hi ,
First shudown the servers and then VA. Dont do otherway which will result in file/database curruption.

one more important thing ensure that no other server is using the VA storage. if so un mount the VA volumes mounted in othere servers as well.

May I know what is the activity planned?
If any activity need to be done on VA side you can do it in online itself.

Thanks and regards

We are doing some maintenance of room.
Also How much max. time I can Put VA & FC60 Without Power because I heard that If it is kept longtime in Off Condition LUN Configuration information may be lost.
thanks.
